Stopping Fraud in Its Tracks: The Future of Transaction Fraud Detection in Singapore
Fraud doesn’t knock—it slips through unnoticed until it’s too late.
As digital payments accelerate across Singapore, financial institutions face a mounting challenge: detecting fraudulent transactions in real time, without slowing down legitimate users. From phishing scams and mule accounts to synthetic identities and account takeovers, transaction fraud has become smarter, faster, and harder to catch.
This blog explores how transaction fraud detection is evolving in Singapore, the gaps still present in legacy systems, and how AI-driven tools are helping financial institutions fight back.

Why Transaction Fraud Detection Is Critical in Singapore
Singapore’s position as a fintech hub comes with exposure to increasingly sophisticated fraud schemes. According to the Singapore Police Force, scam-related crimes in 2024 accounted for over 70% of all crimes reported, with transaction fraud and unauthorised transfers making up a large portion of the losses.
The government’s drive for real-time payments — from PayNow to FAST — adds pressure on banks and fintechs to detect fraud instantly, without delaying genuine transactions.
Missed fraud isn’t just a financial risk — it erodes trust. And in Singapore’s tightly regulated environment, trust is everything.
Types of Transaction Fraud Facing Financial Institutions
Understanding the tactics fraudsters use is the first step toward stopping them. In Singapore, common forms of transaction fraud include:
1. Account Takeover (ATO)
Fraudsters use stolen credentials to gain control over an account and initiate transfers, bill payments, or cash withdrawals — often within minutes.
2. Social Engineering Scams
Victims are tricked into authorising payments themselves under false pretences — for example, investment scams, job scams, or fake relationships.
3. Money Muling
Fraudsters use mule accounts — often belonging to unsuspecting individuals — to route stolen or laundered funds through multiple hops.
4. Real-Time Payment Exploits
With instant transfer systems, once funds are sent, they’re often impossible to recover. Fraudsters exploit this urgency and invisibility.
5. Business Email Compromise (BEC)
Corporate payments are manipulated through phishing or spoofing attacks, redirecting funds to illicit accounts under false vendor names.

Challenges in Transaction Fraud Detection
Despite investment in fraud controls, many Singaporean financial institutions still face persistent roadblocks:
1. High False Positives
Basic rules-based systems raise alerts for normal user behaviour, overwhelming fraud teams and increasing friction for genuine customers.
2. Lack of Real-Time Detection
Many systems rely on batch processing or delayed scoring, leaving gaps for fraudsters to exploit instant payment rails.
3. Inability to Detect Novel Patterns
Fraudsters constantly change tactics. Systems that only recognise known fraud signatures are easily bypassed.
4. Poor Cross-Border Visibility
Singapore is deeply integrated into global financial flows. A lack of insight into transaction trails beyond borders makes it harder to detect layered laundering and syndicated fraud.
What Effective Transaction Fraud Detection Looks Like Today
Modern fraud detection is about being predictive, not just reactive. Here's what best-in-class solutions offer:
AI + Machine Learning
Rather than using only static rules, intelligent systems learn from historical patterns, adapt to new behaviours, and improve accuracy over time.
Behavioural Profiling
These systems build user profiles based on login patterns, spending habits, device data, and more — flagging anything outside the norm in real time.
Network Analysis
Sophisticated fraud often involves mule networks or linked entities. Graph analysis helps identify suspicious linkages between accounts.
Federated Intelligence Sharing
Platforms like Tookitaki’s AFC Ecosystem allow institutions to benefit from typologies and red flags contributed by others — without sharing sensitive data.
Explainable AI
Regulators require transparency. Solutions must explain why a transaction was flagged, not just that it was.
How Tookitaki Is Powering Smarter Fraud Detection
Tookitaki’s FinCense platform is purpose-built to detect transaction fraud in real time. Here’s how it helps Singapore-based institutions stay ahead:
- Agentic AI Framework: Modular AI agents continuously scan transactions, user behaviour, and risk context to identify fraud patterns — even emerging ones.
- Scenario-Based Detection: Leverages real-world fraud scenarios from the AFC Ecosystem, including scams unique to Southeast Asia like fake job recruitment and QR-enabled mule layering.
- Real-Time Simulation & Threshold Optimisation: Before deploying rules, institutions can simulate detection impact to reduce false positives.
- Smart Disposition Engine: AI-generated summaries assist investigators by surfacing key risk insights for flagged transactions.
- Federated Learning: Combines privacy-preserving AI with community-sourced intelligence for faster, more adaptive detection.
Whether you’re a digital bank, a payment gateway, or a traditional financial institution, FinCense provides the flexibility, speed, and accuracy needed for the Singaporean fraud landscape.
Key Strategies for Singaporean Firms to Strengthen Fraud Defences
1. Upgrade From Rule-Based to Hybrid Systems
A combination of dynamic rules and machine learning provides greater precision and adaptability.
2. Focus on Early Detection
Identify mule accounts, layered transfers, and behaviour anomalies before the fraud is completed.
3. Enable Seamless Analyst Workflows
Reduce alert fatigue with AI-driven prioritisation and investigation summaries.
4. Join Intelligence-Sharing Networks
Collaborate with platforms like the AFC Ecosystem to keep up with evolving fraud typologies.
5. Design for Real-Time Action
Ensure that fraud decisions can be made in milliseconds — and tie detection systems directly to block/hold actions.
Conclusion: Fraudsters Are Getting Smarter. Are You?
In Singapore’s fast-moving financial ecosystem, transaction fraud detection is no longer just a compliance function — it’s a competitive advantage.
Banks and fintechs that invest in modern, intelligent fraud prevention are not only protecting their bottom line — they’re protecting their brand and customer relationships.
📌 The future of fraud detection is proactive, predictive, and powered by community-led intelligence. Don’t just keep up — get ahead.
