The financial landscape is evolving rapidly. With this evolution comes an increase in financial crimes, particularly fraud.

Financial institutions are constantly seeking ways to enhance their fraud detection and prevention mechanisms. Traditional methods, while effective to some extent, often fall short in the face of sophisticated fraudulent schemes.

Enter machine learning. This technology has emerged as a game-changer in the banking sector, particularly in fraud detection.

Machine learning algorithms can sift through vast volumes of transaction data, identifying patterns and anomalies indicative of fraudulent activities. This ability to learn from historical data and predict future frauds is revolutionising the way financial institutions approach fraud detection.

However, the implementation of machine learning in fraud detection is not without its challenges. Distinguishing between legitimate transactions and suspicious activity, ensuring data privacy, and maintaining regulatory compliance are just a few of the hurdles to overcome.

This article aims to provide a comprehensive overview of fraud detection using machine learning in banking. It will delve into the evolution of fraud detection, the role of machine learning, its implementation, and the challenges faced.

By the end, financial crime investigators and other professionals in the banking sector will gain valuable insights into this cutting-edge technology and its potential in enhancing their fraud detection strategies.

The Evolution of Fraud Detection in Banking

The banking sector has always been a prime target for fraudsters. Over the years, the methods used to commit fraud have evolved, becoming more complex and sophisticated.

In response, financial institutions have had to adapt their fraud detection systems. Traditional fraud detection methods relied heavily on rule-based systems and manual investigations. These systems were designed to flag transactions that met certain predefined criteria indicative of fraud.

However, as the volume of transactions increased with the advent of digital banking, these traditional systems began to show their limitations. They struggled to process the vast amounts of transaction data, leading to delays in fraud detection and prevention.

Moreover, rule-based systems were often unable to detect new types of fraud that did not fit into their predefined rules. This led to a high number of false negatives, where fraudulent transactions went undetected.

The need for a more effective solution led to the exploration of machine learning for fraud detection.

Traditional Fraud Detection vs. Machine Learning Approaches

Traditional fraud detection systems, while useful, often lacked the ability to adapt to new fraud patterns. They were rigid, relying on predefined rules that could not capture the complexity of evolving fraudulent activities.

Machine learning, on the other hand, offers a more dynamic approach. It uses algorithms that learn from historical transaction data, identifying patterns and anomalies that may indicate fraud. This ability to learn and adapt makes machine learning a powerful tool in detecting and predicting future frauds.

Moreover, machine learning can handle large volumes of data, making it ideal for the digital banking environment where millions of transactions occur daily.

Limitations of Conventional Systems in the Digital Age

In the digital age, the volume, velocity, and variety of transaction data have increased exponentially. Traditional fraud detection systems, designed for a less complex era, struggle to keep up.

These systems often generate a high number of false positives, flagging legitimate transactions as suspicious. This not only leads to unnecessary investigations but can also result in a poor customer experience.

Furthermore, conventional systems are reactive, often detecting fraud after it has occurred. In contrast, machine learning allows for proactive fraud detection, identifying potential fraud before it happens. This shift from a reactive to a proactive approach is crucial in minimising financial loss and protecting customer trust.

Machine Learning: A Game Changer in Fraud Detection

Machine learning has emerged as a game changer in the field of fraud detection. Its ability to learn from data and adapt to new patterns makes it a powerful tool in the fight against financial fraud.

Machine learning algorithms can analyze vast amounts of transaction data in real-time. They can identify complex patterns and subtle correlations that may indicate fraudulent activity. This level of analysis is beyond the capabilities of traditional rule-based systems.

Moreover, machine learning can predict future frauds based on historical data. This predictive capability allows financial institutions to take proactive measures to prevent fraud, rather than reacting after the fact.

Machine learning also reduces the number of false positives. It can distinguish between legitimate transactions and suspicious activity with a high degree of accuracy. This not only saves resources but also improves the customer experience.

However, implementing machine learning in fraud detection is not without its challenges. It requires high-quality data, continuous model training, and a deep understanding of the underlying algorithms.

Understanding Machine Learning Algorithms in Banking

Machine learning algorithms can be broadly classified into supervised and unsupervised learning models. Supervised learning models are trained on labeled data, where the outcome of each transaction (fraudulent or legitimate) is known. These models learn to predict the outcome of new transactions based on this training.

Unsupervised learning models, on the other hand, do not require labeled data. They identify patterns and anomalies in the data, which can indicate potential fraud. These models are particularly useful in detecting new types of fraud that do not fit into known patterns.

Both supervised and unsupervised learning models have their strengths and weaknesses. The choice of model depends on the specific requirements of the financial institution and the nature of the data available.

Regardless of the type of model used, the effectiveness of machine learning in fraud detection depends largely on the quality of the data and the accuracy of the model training.

Real-Time Transaction Monitoring with Machine Learning

One of the key advantages of machine learning is its ability to process and analyse large volumes of data in real-time. This is particularly important in the context of digital banking, where transactions occur around the clock and across different channels.

Real-time transaction monitoring allows financial institutions to detect and prevent fraud as it happens. Machine learning algorithms can analyse each transaction as it occurs, flagging any suspicious activity for immediate investigation.

This real-time analysis is not limited to the transaction itself. Machine learning models can also analyze the context of the transaction, such as the customer's typical behavior, the time and location of the transaction, and other relevant factors.

This comprehensive analysis allows for more accurate fraud detection, reducing both false positives and false negatives. It also enables financial institutions to respond quickly to potential fraud, minimising financial loss and protecting customer trust.

Implementing Machine Learning Models for Fraud Detection

Implementing machine learning models for fraud detection requires a strategic approach. It's not just about choosing the right algorithms, but also about understanding the data and the business context.

The first step is to define the problem clearly. What type of fraud are you trying to detect? What are the characteristics of fraudulent transactions? What data is available for analysis? These questions will guide the choice of machine learning model and the design of the training process.

Next, the data needs to be prepared for analysis. This involves cleaning the data, handling missing values, and transforming variables as needed. The quality of the data is crucial for the performance of the machine learning model.

Once the data is ready, the machine learning model can be trained. This involves feeding the model with the training data and allowing it to learn from it. The model's performance should be evaluated and fine-tuned as necessary.

Finally, the model needs to be integrated into the existing fraud detection system. This requires careful planning and testing to ensure that the model works as expected and does not disrupt the existing processes.

Supervised vs. Unsupervised Learning in Fraud Detection

In the context of fraud detection, both supervised and unsupervised learning models have their uses. The choice between the two depends on the nature of the problem and the data available.

Supervised learning models are useful when there is a large amount of labeled data available. These models can learn from past examples of fraud and apply this knowledge to detect future frauds. However, they may not be as effective in detecting new types of fraud that do not fit into known patterns.

Unsupervised learning models, on the other hand, do not require labeled data. They can identify patterns and anomalies in the data, which can indicate potential fraud. These models are particularly useful in detecting new types of fraud that do not fit into known patterns.

Regardless of the type of model used, the effectiveness of machine learning in fraud detection depends largely on the quality of the data and the accuracy of the model training.

The Role of Data Quality and Model Training

Data quality plays a crucial role in the effectiveness of machine learning models for fraud detection. High-quality data allows the model to learn accurately and make reliable predictions.

Data quality involves several aspects, including accuracy, completeness, consistency, and timeliness. The data should accurately represent the transactions, be complete with no missing values, be consistent across different sources, and be up-to-date.

Model training is another critical factor in the success of machine learning for fraud detection. The model needs to be trained on a representative sample of the data, with a good balance between fraudulent and legitimate transactions.

The model's performance should be evaluated and fine-tuned as necessary. This involves adjusting the model's parameters, retraining the model, and validating its performance on a separate test set.

Continuous monitoring and updating of the model is also essential to ensure that it remains effective as new patterns of fraud emerge.

Challenges in Machine Learning-Based Fraud Detection

Despite the potential of machine learning in fraud detection, there are several challenges that financial institutions need to address. One of the main challenges is the complexity of financial transactions.

Financial transactions involve numerous variables and can follow complex patterns. This complexity can make it difficult for machine learning models to accurately identify fraudulent transactions.

Another challenge is the imbalance in the data. Fraudulent transactions are relatively rare compared to legitimate transactions. This imbalance can lead to models that are biased towards predicting transactions as legitimate, resulting in a high number of false negatives.

The dynamic nature of fraud is another challenge. Fraudsters continuously adapt their tactics to evade detection. This means that machine learning models need to be regularly updated to keep up with new patterns of fraud.

Finally, there are challenges related to data privacy and security. Financial transactions involve sensitive personal information. Financial institutions need to ensure that this data is handled securely and that privacy is maintained.

Distinguishing Legitimate Transactions from Fraudulent Activity

Distinguishing between legitimate transactions and fraudulent activity such as credit card fraud is a key challenge in fraud detection. This is particularly difficult because fraudulent transactions often mimic legitimate ones.

Machine learning models can help to address this challenge by identifying patterns and anomalies in the data. However, these models need to be trained on high-quality data and need to be regularly updated to keep up with changing patterns of fraud.

False positives are another concern. These occur when legitimate transactions are incorrectly flagged as fraudulent. This can lead to unnecessary investigations and can disrupt the customer experience. Strategies to minimise false positives include refining the model's parameters and incorporating feedback from fraud investigators.

Ethical and Privacy Considerations in Data Usage

The use of machine learning in fraud detection raises several ethical and privacy considerations. One of the main concerns is the use of personal transaction data.

Financial institutions need to ensure that they are complying with data protection regulations. This includes obtaining the necessary consents for data usage and ensuring that data is stored securely.

There is also a need for transparency in the use of machine learning. Customers should be informed about how their data is being used and how decisions are being made. This can help to build trust and can also provide customers with the opportunity to correct any inaccuracies in their data.

Finally, there are ethical considerations related to the potential for bias in machine learning models. Financial institutions need to ensure that their models are fair and do not discriminate against certain groups of customers. This requires careful design and testing of the models, as well as ongoing monitoring of their performance.

Financial Institutions Winning the Fight Against Fraud

Financial institutions are increasingly turning to machine learning to combat fraud. This is not just limited to large multinational banks. Smaller banks and credit unions are also adopting these technologies, often in partnership with fintech companies.

One example is the Royal Bank of Scotland, which uses machine learning to analyze customer behaviour and identify unusual patterns. This has helped the bank to detect and prevent fraud, improving customer trust and reducing financial loss.

Another example is Danske Bank, which uses machine learning to detect money laundering. The bank's machine learning model analyses transaction data and flags suspicious activity for further investigation. This has helped the bank to comply with anti-money laundering regulations and has also reduced the cost of investigations.

These examples show that machine learning is not just a tool for the future. It is already being used today, helping financial institutions to win the fight against fraud.

{{cta-ebook}}

The Future of Fraud Detection in Banking

The future of fraud detection in banking is promising, with machine learning playing a central role. As technology continues to evolve, so too will the methods used to detect and prevent fraud.

Machine learning models will become more sophisticated, capable of analysing larger volumes of data and identifying more complex patterns of fraudulent activity. This will enable financial institutions to detect fraud more quickly and accurately, reducing financial loss and improving customer trust.

At the same time, the integration of machine learning with other technologies, such as artificial intelligence and blockchain, will enhance fraud detection capabilities. These technologies will provide additional layers of security, making it even harder for fraudsters to succeed.

The future will also see greater collaboration between financial institutions, fintech companies, and law enforcement agencies. By sharing data and insights, these organizations can work together to combat financial fraud more effectively.

Emerging Trends and Technologies

Several emerging trends and technologies are set to shape the future of fraud detection in banking. One of these is deep learning, a subset of machine learning that uses neural networks to analyse data. Deep learning can identify complex patterns and correlations in data, making it a powerful tool for detecting fraud.

Another trend is the use of behavioural biometrics, which analyses the unique ways in which individuals interact with their devices. This can help to identify fraudulent activity, as fraudsters will interact with devices in different ways to legitimate users.

Finally, the use of consortium data and shared intelligence will become more common. By pooling data from multiple sources, financial institutions can build more accurate and robust machine learning models for fraud detection.

Preparing for the Next Wave of Financial Crimes

As technology evolves, so too do the methods used by fraudsters. Financial institutions must therefore be proactive in preparing for the next wave of financial crimes. This involves staying up-to-date with the latest trends and technologies in fraud detection, and continuously updating and refining machine learning models.

Financial crime investigators will also need to develop new skills and expertise. This includes understanding how machine learning works, and how it can be applied to detect and prevent fraud. Training and professional development will therefore be crucial.

Finally, financial institutions will need to adopt a multi-layered security approach. This involves using a range of technologies and methods to detect and prevent fraud, with machine learning being just one part of the solution. By doing so, they can ensure that they are well-prepared to combat the ever-evolving threat of financial fraud.

MAS Notice 626 Transaction Monitoring Requirements: A Compliance Guide for Singapore Banks

For banks in Singapore, MAS Notice 626 remains one of the most important foundations of AML compliance. Issued by the Monetary Authority of Singapore, the Notice sets out clear expectations around customer due diligence, transaction monitoring, suspicious transaction reporting, and record-keeping.

This guide focuses on MAS transaction monitoring obligations under MAS Notice 626 and explains what they mean in practice for compliance teams navigating evolving Singapore AML requirements in 2026.

Talk to an Expert

What Is MAS Notice 626?

MAS Notice 626 applies to banks licensed under Singapore’s Banking Act. It forms a core part of the country’s AML/CFT framework and reflects broader international standards, including the FATF Recommendations. It is also supported by MAS Guidelines on AML/CFT, which help banks interpret the rules in practice.

At a high level, MAS Notice 626 covers four key areas:

  • customer due diligence
  • ongoing monitoring
  • suspicious transaction reporting
  • record-keeping

For most compliance teams, the most operationally demanding areas are ongoing monitoring and transaction monitoring.

Why MAS Notice 626 Matters for Singapore Banks

Regulators in Singapore have made it clear that AML controls must be more than procedural. MAS has taken enforcement action against banks where weaknesses in monitoring, customer oversight, or investigation processes created gaps in AML/CFT controls.

That is why MAS AML compliance is not simply about maintaining policies. Banks must be able to show that their controls work in practice, especially when it comes to identifying unusual or suspicious activity. In this context, MAS transaction monitoring is one of the most important operational pillars of a bank’s AML framework.

Ongoing Monitoring Requirements Under MAS Notice 626

Paragraph 11 of MAS Notice 626 requires banks to perform ongoing monitoring of customer relationships. In practice, this includes two connected obligations: monitoring transactions and keeping customer information current.

Transaction Monitoring Under MAS Notice 626

Banks must monitor transactions to ensure they are consistent with what the bank knows about the customer, the customer’s business, and the customer’s risk profile.

In practice, this means banks should be able to:

  • understand the customer’s expected transaction behaviour
  • detect activity that does not align with that expected pattern
  • scrutinise the source and destination of unusual funds
  • apply enhanced monitoring to high-risk customers and PEPs

This is central to MAS transaction monitoring. The expectation is not only to detect unusual activity, but to assess it in the context of customer risk, expected behaviour, and potential financial crime exposure.

Keeping Customer Due Diligence Information Up to Date

Ongoing monitoring under MAS Notice 626 is not limited to transaction review. Banks must also ensure that customer due diligence information remains accurate and up to date, particularly for higher-risk customers.

If transaction monitoring reveals a meaningful shift in customer behaviour, that should trigger a CDD review. This is an important part of meeting broader Singapore AML requirements, where customer knowledge and transaction behaviour are expected to remain aligned.

What MAS Expects From Transaction Monitoring Systems

MAS has clarified over time what effective monitoring should look like in practice. Several expectations are particularly relevant for banks strengthening their MAS AML compliance frameworks.

1. A Risk-Based Monitoring Approach

A core principle of MAS Notice 626 is that monitoring should be risk-based. Not all customers present the same level of AML/CFT risk, and transaction monitoring should reflect that.

Higher-risk customers, including PEPs, customers linked to high-risk jurisdictions, and customers with complex ownership structures, should be subject to more intensive monitoring. A one-size-fits-all model is unlikely to meet regulatory expectations under modern Singapore AML requirements.

2. Typology Coverage That Reflects Real Risk

MAS expects banks to monitor for the money laundering typologies most relevant to Singapore’s financial system.

These include risks such as:

  • trade-based money laundering
  • misuse of shell companies and nominees
  • placement through casino-linked activity
  • abuse of digital payment channels

This means MAS transaction monitoring systems should reflect the real typologies facing Singapore banks, rather than relying on generic scenario libraries that may not match local risk.

3. Alert Quality Over Alert Volume

MAS has also emphasised that more alerts do not automatically mean better monitoring. A system generating high volumes of low-value alerts can create operational noise rather than real control strength.

Banks should be able to demonstrate that thresholds are producing alerts that are relevant, actionable, and properly investigated. Strong MAS AML compliance depends not just on detection, but on the quality of the monitoring outcomes.

4. Documentation and Audit Trail

All monitoring activity should be documented clearly. That includes how alerts are generated, how they are investigated, what decisions are made, and whether escalation to suspicious transaction reporting is necessary.

MAS examiners are likely to review:

  • alert workflows
  • investigation records
  • disposition decisions
  • STR-related documentation

For banks in Singapore, this is a critical part of meeting Singapore AML requirements and showing that the monitoring framework is working as intended.

MAS Notice 626 transaction monitoring overview

MAS Notice 626 and Correspondent Banking

Banks with correspondent banking relationships face additional monitoring expectations under MAS Notice 626.

MAS requires enhanced scrutiny of these relationships, including:

  • understanding the nature and expected volume of activity
  • monitoring for patterns inconsistent with the correspondent’s profile
  • applying payable-through account controls where relevant
  • periodically reviewing whether the relationship remains appropriate

This reflects the higher risks often associated with cross-border flows and nested financial relationships.

Suspicious Transaction Reporting Under MAS Notice 626

Transaction monitoring is often the first stage in identifying conduct that may require a suspicious transaction report. Under MAS Notice 626, banks are expected to file STRs with the Suspicious Transaction Reporting Office within a reasonable timeframe once suspicion is formed.

Key obligations include:

  • file an STR as soon as suspicion arises
  • do not wait for a minimum threshold, as none applies
  • avoid tipping off the subject of the report
  • retain the monitoring alert and investigation records that led to the STR
  • ensure the STR contains enough information for STRO to act on it

This is where MAS transaction monitoring connects directly with reporting obligations. A bank’s monitoring system must support not only detection, but also sound investigation and reporting processes.

Tipping Off Risk and MAS AML Compliance

One of the most sensitive legal areas within MAS AML compliance is the prohibition on tipping off. Under Singapore law, tipping off is a criminal offence.

That means transaction monitoring and case management systems must be designed carefully so staff do not inadvertently alert a customer whose account or activity is under review.

MAS Notice 626 in the Context of Singapore AML Requirements

MAS Notice 626 should also be viewed in the wider context of Singapore’s broader AML priorities. Singapore’s National Anti-Money Laundering Strategy, published in 2023, signals how the country is thinking about the future of financial crime prevention.

Several themes are especially relevant.

Digital Payment Monitoring

With PayNow and other digital payment channels widely used in Singapore, monitoring frameworks can no longer focus only on traditional wire transfers. Instant payment flows also need to be covered effectively.

This makes real-time monitoring increasingly important within MAS transaction monitoring programmes.

Data Collaboration and Shared Intelligence

The launch of initiatives such as COSMIC suggests that regulators increasingly expect financial institutions to benefit from intelligence sharing, not just internal monitoring signals.

This points to a more connected model of AML detection, where external intelligence can strengthen how banks respond to evolving risks under Singapore AML requirements.

Technology and Innovation

MAS has consistently encouraged financial institutions to adopt RegTech and advanced analytics where these improve AML effectiveness. AI and machine learning-based systems that identify layered, fast-moving, or complex suspicious patterns are increasingly aligned with supervisory expectations.

How Tookitaki Supports MAS Notice 626 Compliance

Tookitaki’s FinCense platform is designed to support the practical demands of MAS Notice 626, especially in areas tied to MAS transaction monitoring and broader MAS AML compliance.

This includes:

  • a federated typology network covering Singapore-relevant risks such as trade-based money laundering and PEP monitoring
  • risk-based alert scoring that supports differentiated monitoring by customer risk
  • full audit trails across alert investigation workflows
  • real-time monitoring for PayNow and other digital payment activity
  • support for STRO reporting workflows
  • explainable AI outputs that help investigators understand and document alert rationale

For banks looking to modernise their AML stack, these capabilities align closely with current Singapore AML requirements and MAS’s technology-forward direction.

Why Effective MAS Transaction Monitoring Matters

The message from regulators is clear. Banks are expected not only to maintain transaction monitoring controls, but to prove that those controls are risk-based, well-calibrated, and effective in practice.

That means banks should be able to:

  • monitor customer behaviour against expected patterns
  • detect Singapore-relevant AML typologies
  • generate alerts that investigators can act on
  • maintain clear investigation and audit records
  • connect monitoring outcomes to STR and CDD review workflows

In short, MAS transaction monitoring is one of the clearest tests of whether a bank’s AML programme is truly working.

MAS Notice 626 Transaction Monitoring: Key Takeaways

For banks reviewing their transaction monitoring capabilities, the priorities are clear:

  • risk-based monitoring linked to customer risk ratings
  • typology coverage that reflects Singapore-specific ML/TF risks
  • stronger alert quality supported by documented investigations
  • real-time monitoring across digital payment channels
  • STR workflows that meet regulatory expectations and reduce tipping off risk
  • regular threshold review and calibration
  • documentation that supports supervisory review and audit readiness

MAS Notice 626 is not just a regulatory framework to reference. It is a practical benchmark for how banks should approach monitoring, investigation, and reporting.

For compliance teams working under evolving Singapore AML requirements, strong transaction monitoring is both a regulatory necessity and an operational advantage. It is what turns AML compliance from a static control framework into a working system that can detect risk in real time.

The QR Code Trap: Why a Simple Scan Is Becoming a Serious Fraud Risk in the Philippines

The most dangerous payment scams do not always look suspicious. Sometimes, they look efficient.

A customer scans a QR code at a shop counter, enters the amount, and completes the payment in seconds. There is no failed transaction, no login alert, no obvious red flag. Everything works exactly as it should. Except the money does not go to the merchant. It goes somewhere else. That is the core risk behind the BSP’s recent warning on “quishing,” including cases where a legitimate merchant QR code may be altered, tampered with, or placed over by another code so payments are redirected to a scammer’s account.

At one level, this sounds like a classic consumer-awareness issue. Check the code. Verify the source. Be careful what you scan. All of that is true. But stopping there misses the bigger point. In the Philippines, QR payments are no longer a novelty. They are part of a broader digital payments ecosystem that has scaled quickly, with digital retail payments accounting for 57.4 percent of monthly retail transaction volume, while QR Ph continues to serve as the national interoperable QR standard for participating banks and non-bank e-money issuers.

That changes the conversation.

Because once QR payments become normal, QR fraud stops being a side story. It becomes a payment-risk issue, a merchant-risk issue, and increasingly, a fraud-and-AML issue wrapped into one.

Talk to an Expert

Why this scam matters more than it first appears

What makes QR code scams so effective is not technical sophistication. It is behavioural precision.

Fraudsters do not need to break into a banking app or compromise a device. They simply exploit trust at the point of payment. A sticker placed over a legitimate merchant code can do what phishing links, fake websites, and spoofed calls often try much harder to achieve: redirect money through a transaction the customer willingly authorises. The BSP warning itself highlights the practical advice consumers should follow, including checking whether a QR code appears altered, tampered with, or placed over another code before scanning. That guidance is telling in itself. It signals that physical manipulation of QR payment points is now a live concern.

For professionals in compliance and fraud, that should immediately raise a harder question. If the payment is customer-authorised and the beneficiary account is valid, what exactly is the institution supposed to detect?

The answer is not always the payment instruction itself. It is the pattern surrounding it.

A scam built for a real-time world

The Philippines has spent years building a more interoperable and inclusive digital payments landscape. QR Ph was developed so a common QR code could be scanned and interpreted by any participating bank or non-bank EMI, making person-to-person and person-to-merchant payments easier across providers. That is good infrastructure. It reduces friction, supports adoption, and brings more merchants into the formal digital economy.

But reduced friction has a downside. It also reduces hesitation.

In older payment settings, there were often natural pauses. A card terminal, a manual account check, a branch interaction, a payment slip. QR payments compress that journey. The customer sees the code, scans it, and moves on. That is the whole point of the experience. It is also why this scam is so well suited to modern payment habits.

Criminals have understood something simple: if a system is built around speed and convenience, the easiest place to attack is the moment when people stop expecting to verify anything.

How the QR code scam typically unfolds

The mechanics are almost painfully straightforward.

A fraudster identifies a merchant that relies on a visible static QR code. That could be a stall, a café, a small retail counter, a delivery collection point, or any setup where the code is printed and left on display. The original code is then covered or replaced with another one linked to a scammer-controlled account or a mule account.

Customers continue paying as usual. They do not think they are sending money to an individual or a different beneficiary. They think they are paying the merchant. The merchant, meanwhile, may not realise anything is wrong until expected payments fail to reconcile.

At that point, the payment journey has already begun.

Funds start landing in the receiving account, often in the form of multiple low-value payments from unrelated senders. In isolation, these do not necessarily look suspicious. In fact, they may resemble ordinary merchant collections. That is what makes this scam harder than it sounds. It can create merchant-like inflows in an account that should not really be behaving like a merchant account at all.

Then comes the real risk. The funds are moved quickly. Split across other accounts. Sent to wallets. Withdrawn in cash. Layered through secondary recipients. The initial fraud is simple. The downstream movement can be much more organised.

That is where the scam begins to overlap with laundering behaviour.

Why fraud teams and AML teams should both care

It is easy to classify QR code payment scams as retail fraud and leave it there. That would be too narrow.

From a fraud perspective, the problem is payment diversion. A customer intends to pay a merchant but sends funds elsewhere.

From an AML perspective, the problem is what happens next. Once diverted funds begin flowing into accounts that collect, move, split, and exit value quickly, institutions are no longer looking at a single fraudulent payment. They are looking at a potential collection-and-layering mechanism hidden inside legitimate payment rails.

This matters because the scam does not need large values to become meaningful. A QR fraud ring does not need one massive transfer. It can rely on volume, repetition, and velocity. Small payments from many victims can create a steady stream of illicit funds that looks unremarkable at transaction level but far more suspicious in aggregate.

That is why the typology deserves more serious treatment. It lives in the overlap between fast payments, mule-account behaviour, and low-friction laundering.

The QR code scam warning

The detection challenge is not the scan. It is the behaviour after the scan.

Most legacy controls were not built for this.

Traditional monitoring logic often performs best when something is clearly out of character: an unusually large transaction, a high-risk jurisdiction, a sanctions hit, a known suspicious counterparty, or a classic account takeover pattern. QR scams may present none of those signals at the front end. The customer has not necessarily been hacked. The payment amount may be ordinary. The transfer rail is legitimate. The receiving account may not yet be watchlisted.

So the wrong question is: how do we detect every suspicious QR payment?

The better question is: how do we detect an account whose behaviour no longer matches its expected role?

That is a much more useful lens.

If a newly opened or low-activity account suddenly begins receiving merchant-like inbound payments from many unrelated individuals, that should matter. If those credits are followed by rapid outbound transfers or repeated cash-out behaviour, that should matter more. If the account sits inside a broader network of linked beneficiaries, shared devices, repeated onward transfers, or mule-like activity patterns, then the case becomes stronger still.

In other words, the problem is behavioural inconsistency, not just transactional abnormality.

Why this is becoming a real-time monitoring problem

This scam is particularly uncomfortable because it plays out at the speed of modern payments.

The BSP’s own digital payments reporting shows how mainstream digital retail payments have become in the Philippines. When money moves that quickly through interoperable rails, institutions lose the luxury of treating suspicious patterns as something to review after the fact. By the time a merchant notices missing collections, an operations team reviews exceptions, or a customer dispute is logged, the funds may already have been transferred onward.

That shifts the burden from retrospective review to timely pattern recognition.

This is not about flagging every small QR payment. That would be unworkable and noisy. It is about identifying where a stream of seemingly routine payments is being routed into an account that starts exhibiting the wrong kind of velocity, concentration, or onward movement.

The intervention window is narrow. That is what makes this a real-time problem, even when the scam itself is physically low-tech.

The merchant ecosystem is an exposed surface

There is also a more uncomfortable operational truth here.

QR-based payment growth often depends on simplicity. Merchants, especially smaller ones, benefit from static printed codes that are cheap, easy to display, and easy for customers to use. But static codes are also easier to tamper with. In some environments, a fraudster does not need cyber capability. A printed overlay is enough.

That does not mean QR adoption is flawed. It means the ecosystem carries a visible attack surface.

The BSP and related QR Ph materials have consistently framed QR Ph as a way to make digital payments interoperable and more convenient for merchants and consumers, including smaller businesses and users beyond traditional card acceptance footprints. That inclusion benefit is real. It is also why institutions need to think carefully about what fraud controls look like when convenience extends to low-cost, visible, physically accessible payment instruments.

In plain terms, if the front-end payment instrument can be tampered with in the real world, then the back-end monitoring has to be smarter.

What better monitoring looks like in practice

The right response to this typology is not a flood of rules. It is a better sense of account behaviour, role, and connected movement.

Institutions should be asking whether they can tell the difference between a genuine merchant collection profile and a personal or mule account trying to imitate one. They should be able to examine how quickly inbound funds are moved onward, whether those patterns are sudden or sustained, whether counterparties are unusually diverse, and whether linked accounts show signs of coordinated activity.

They should also be able to connect fraud signals and AML signals instead of treating them as separate universes. In a QR diversion case, the initial trigger may sit with payment fraud, but the onward flow often sits closer to mule detection and suspicious movement analysis. If those two views are not connected, the institution sees only fragments of the story.

That is where stronger case management, behavioural scoring, and scenario-led monitoring become important.

And this is exactly why Tookitaki’s positioning matters in a case like this. A typology such as QR payment diversion does not demand more noise. It demands better signal. It demands the ability to recognise when an account is behaving outside its expected role, when transaction velocity starts to look inconsistent with ordinary retail activity, and when scattered data points across fraud and AML should really be read as one emerging pattern. For banks and fintechs dealing with increasingly adaptive scams, that shift from isolated alerting to connected intelligence is not a nice-to-have. It is the difference between seeing the payment and seeing the scheme.

A small scam can still reveal a much bigger shift

There is a tendency in financial crime writing to chase the dramatic case. The million-dollar fraud. The cross-border syndicate. The major arrest. Those stories matter, but smaller scams often tell you more about where the system is becoming vulnerable.

This one does exactly that.

A QR code replacement scam is not flashy. It is not technically grand. It may even look mundane compared with deepfakes, synthetic identities, or complex APP fraud chains. But it tells us something important about the current payments environment: fraudsters are increasingly happy to exploit trust, convenience, and physical access instead of sophisticated intrusion. That is not backward. It is efficient.

And for institutions, efficiency is exactly what makes it dangerous.

Because if a criminal can redirect funds without stealing credentials, without breaching an app, and without triggering an obvious failure in the payment experience, then the burden of defence shifts downstream. It shifts to monitoring, behavioural intelligence, and the institution’s ability to recognise when a legitimate payment journey has produced an illegitimate result.

Conclusion: the payment worked, but the control failed

That is the real sting in this typology.

The payment works. The rails work. The customer experience works. What fails is the assumption underneath it.

The BSP’s recent warning on quishing should be read as more than a consumer caution. It is a signal that as digital payments deepen in the Philippines, some of the next fraud risks will come not from breaking the payment system, but from quietly misdirecting trust within it.

For compliance teams, fraud leaders, and risk professionals, the lesson is clear. The problem is no longer limited to whether a transaction was authorised. The harder question is whether the institution can recognise, early enough, when a transaction that looks routine is actually the first step in a scam-and-laundering chain.

That is what makes this worth paying attention to.

Not because it is dramatic.

Because it is plausible, scalable, and built for the exact kind of payment environment the industry has worked so hard to create.

The 3 Stages of Money Laundering: Placement, Layering, and Integration Explained

Dirty money does not become clean overnight. It moves through a process. Funds are introduced into the financial system, shuffled across accounts and jurisdictions, and eventually reappear as seemingly legitimate income or investment. By the time the cycle is complete, the link to the original crime is often buried beneath layers of transactions.

This is why most money laundering schemes, no matter how sophisticated, follow a familiar pattern. Criminal proceeds typically move through three stages: placement, layering, and integration. Each stage serves a different purpose. Placement gets the money into the system. Layering obscures the trail. Integration makes the funds appear legitimate.

For compliance teams, these stages are more than theoretical concepts. They shape how suspicious activity is detected, how alerts are generated, and how investigations are prioritised. Missing one stage can allow illicit funds to slip through even the most advanced monitoring systems.

This is particularly relevant across APAC. Large remittance flows, cross-border trade, digital payment growth, and high-value asset markets create multiple entry points for laundering activity. Understanding how money moves across placement, layering, and integration helps institutions detect risks earlier and connect seemingly unrelated transactions.

What Is Money Laundering?

Money laundering is the process of disguising the origin of illicit funds so they can be used without attracting attention. The proceeds may come from fraud, corruption, organised crime, cybercrime, or other predicate offences. Regardless of the source, the challenge for criminals is the same: they must make illegal money appear legitimate.

Holding large amounts of cash is risky. Spending it directly can trigger scrutiny. Moving funds through the financial system without explanation raises red flags. Laundering solves this problem by gradually distancing the money from its criminal origin.

Regulatory frameworks are designed to disrupt this process. Transaction monitoring, customer due diligence, sanctions screening, and ongoing monitoring all aim to identify activity that fits the laundering lifecycle. Understanding the three stages helps explain why these controls exist and how they work together.

Stage 1: Placement — Getting Dirty Money into the Financial System

Placement is the entry point. Illicit funds must first be introduced into the financial system before they can be moved or disguised. This is often the riskiest stage for criminals because the money is closest to its source.

Large cash deposits, sudden inflows, or unexplained funds are more likely to attract attention. As a result, criminals try to minimise visibility when placing funds.

How Placement Works

One of the most common methods is structuring, sometimes referred to as smurfing. Instead of depositing a large amount at once, funds are broken into smaller transactions below reporting thresholds. These deposits may be spread across multiple branches, accounts, or individuals to avoid detection.

Cash-intensive businesses are another frequently used channel. Illicit funds are mixed with legitimate business revenue, making it difficult to distinguish between legal and illegal income. Restaurants, retail outlets, and service businesses are commonly used for this purpose.

Currency exchanges and monetary instruments also play a role. Cash may be converted into cashier’s cheques, money orders, or foreign currency before being deposited. This adds an additional step between the funds and their origin.

Digital wallets and prepaid instruments have introduced new placement avenues. Funds can be loaded into e-money platforms and then moved digitally, reducing reliance on traditional cash deposits. This is particularly relevant in markets with high adoption of digital payments.

AML Red Flags at the Placement Stage

Compliance teams typically look for patterns such as:

  • Multiple deposits just below reporting thresholds
  • Cash activity inconsistent with customer profile
  • Sudden increases in cash deposits for low-risk customers
  • Rapid conversion of cash into monetary instruments
  • High cash volume in accounts not expected to handle cash

Placement activity often appears fragmented. Individual transactions may look harmless, but the pattern across accounts reveals the risk.

Stage 2: Layering — Obscuring the Paper Trail

Once funds are inside the financial system, the focus shifts to layering. The goal is to make tracing the origin of money as difficult as possible. This is done by moving funds repeatedly, often across jurisdictions, entities, and financial products.

Layering is typically the most complex stage. It is also where criminals take advantage of the interconnected global financial system.

How Layering Works

International transfers are frequently used. Funds move between multiple accounts in different jurisdictions, sometimes within short timeframes. Each transfer adds distance between the money and its source.

Shell companies and nominee structures are another common tool. Funds are routed through corporate entities where beneficial ownership is difficult to determine. This creates the appearance of legitimate business transactions.

Real estate transactions can also serve layering purposes. Properties may be purchased, transferred, and resold, often through corporate structures. These movements obscure the original funding source.

Cryptocurrency transactions have introduced additional complexity. Mixing services and privacy-focused assets can break the traceability of funds, particularly when combined with traditional banking channels.

Loan-back schemes are also used. Funds are transferred to an entity and then returned as a loan or investment. This creates documentation that appears legitimate, even though the source remains illicit.

AML Red Flags at the Layering Stage

Typical indicators include:

  • Rapid movement of funds across multiple accounts
  • Transactions with no clear business purpose
  • Transfers involving multiple jurisdictions
  • Complex ownership structures with unclear beneficiaries
  • Circular transaction flows between related entities
  • Sudden spikes in cross-border activity

Layering activity often looks like normal financial movement when viewed in isolation. The risk becomes clearer when transactions are analysed as a network rather than individually.

Stage 3: Integration — Entering the Legitimate Economy

Integration is the final stage. By this point, funds have been sufficiently distanced from their origin. The money can now be used with reduced suspicion.

This is where illicit proceeds re-enter the economy as apparently legitimate wealth.

How Integration Works

High-value asset purchases are common. Luxury vehicles, art, jewellery, and other assets can be acquired and later sold, creating legitimate-looking proceeds.

Real estate investments also play a major role. Rental income, resale profits, or property-backed loans provide a credible explanation for funds.

Business investments offer another integration pathway. Laundered money is injected into legitimate businesses, generating revenue that appears lawful.

False invoicing schemes are also used. Payments to shell companies are recorded as business expenses, and the receiving entity reports the funds as legitimate income.

AML Red Flags at the Integration Stage

Compliance teams may observe:

  • Asset purchases inconsistent with customer income
  • Large investments without clear source of wealth
  • Transactions involving offshore entities
  • Sudden wealth accumulation without explanation
  • Unusual business income patterns

At this stage, the activity often appears legitimate on the surface. Detecting integration requires strong customer risk profiling and ongoing monitoring.

How AML Systems Detect the Three Stages

Modern transaction monitoring does not focus on individual transactions alone. It looks for patterns across the entire lifecycle of funds.

At the placement stage, systems identify structuring behaviour, unusual cash activity, and customer behaviour inconsistent with risk profiles.

At the layering stage, network analytics and behavioural models detect unusual fund flows, circular transactions, and cross-border patterns.

At the integration stage, monitoring shifts toward changes in customer wealth, asset purchases, and unexplained income streams.

When these capabilities are combined, institutions can detect laundering activity even when individual transactions appear normal.

Why All Three Stages Matter for APAC Compliance Teams

Each APAC market presents different exposure points. Large remittance corridors increase placement risk. Cross-border trade creates layering opportunities. High-value asset markets enable integration.

This means effective AML programmes cannot focus on just one stage. Detecting placement without analysing layering flows leaves gaps. Monitoring integration without understanding earlier activity limits context.

Understanding the full lifecycle helps compliance teams connect the dots. Transactions that appear unrelated may form part of a single laundering chain when viewed together.

Ultimately, placement introduces risk. Layering hides it. Integration legitimises it. Effective AML detection requires visibility across all three.
