This highlights how AI-powered data processing is crucial for identifying payment risks effectively.
Behavioral Pattern Analysis
Once data is collected, AI systems dive deeper by analyzing user behavior to uncover subtle signs of fraud. They evaluate factors like typing speed, swipe gestures, app usage patterns, and transaction timing to verify identities and identify anomalies. A core component of this process is anomaly detection, where AI flags unusual activities such as sudden spending spikes, irregular login times, or transactions from unexpected locations. Network analysis further helps identify connections between entities that might signal coordinated fraudulent behavior.
The results speak for themselves. For example, American Express used deep learning models to boost fraud detection accuracy by 6%, while PayPal improved real-time fraud detection by 10% using AI-powered behavioral insights. Additional strategies like device fingerprinting create unique profiles based on device-specific details, and AI systems monitor customer behavior in loyalty programs to spot potential fraud. They even analyze invoices and related documents to catch discrepancies. Importantly, these systems continually adapt to new fraud tactics by retraining on fresh data.
"Last year, we harnessed AI to protect over 125 billion payment transactions for our diverse user base. The ability to process and monitor such vast amounts of data on a global scale simply wouldn't be possible without AI." - Sandeep Malhotra, Mastercard's executive vice president for products and innovation in the Asia-Pacific region
Risk Scoring and Automated Decisions
Using insights from data and behavioral analysis, AI assigns risk scores to transactions. These scores are based on factors like transaction amounts, user behavior, device history, and merchant reputation. This enables automated decisions that swiftly approve legitimate transactions while flagging high-risk ones for further review. The scoring process evaluates variables such as spending patterns, transaction history, and real-time account balances, comparing each transaction to patterns learned from millions of others. High-risk transactions are subjected to extra verification, while fraudulent ones are blocked immediately.
Machine learning models continuously refine their understanding of transaction behaviors, outperforming traditional methods. For example, Aeropay's risk engine uses machine learning to adjust decisions based on user activity across its network, achieving approval rates above 90%. Similarly, in fiscal year 2024, the U.S. Department of the Treasury's Office of Payment Integrity used machine learning to prevent and recover over $4 billion in fraudulent and improper payments.
AI-powered risk scoring not only increases accuracy but also minimizes false positives, ensuring legitimate customer transactions proceed smoothly.

Credit and debit cards are the most common targets for fraud, accounting for 84.8% of all fraudulent transactions across industries, according to Sift's fraud benchmarking data. AI uses specific markers to predict and mitigate risks with great accuracy.
Key indicators include CVV mismatches, invalid BINs (Bank Identification Numbers), rapid transaction sequences, unexpected spending surges, and failures in billing address or timing verification during card-not-present transactions.
Major financial institutions like Chase and American Express rely on machine learning to review millions of transactions daily. This allows them to swiftly identify threats such as fraudulent wire transfers, account takeovers, and card skimming activities.
Digital Wallet and Alternative Payment Risks
While digital wallets have a fraud rate of about 1.2%, they still account for approximately 3% of fraudulent transactions. Electronic fund transfers, on the other hand, experience an average fraud rate of 2.1%, which can spike to 20.5% in high-risk sectors like iGaming. Meanwhile, Buy Now, Pay Later (BNPL) services depend on AI to evaluate creditworthiness in real time while also flagging potential identity fraud.
Cryptocurrency transactions, with a 2.7% fraud rate, are another area of focus. AI scrutinizes blockchain activity and wallet addresses to detect anomalies. PayPal has enhanced its real-time fraud detection by 10% through AI, effectively preventing illegal activities like credit card testing scenarios.
To complete the risk assessment, AI incorporates location and device data into its analysis.
Location and Device Verification
AI systems validate transactions by cross-referencing location and device data, ensuring consistency. Geographic or device discrepancies often signal fraudulent activity. In fact, over 60% of operational failures in payment systems result in losses exceeding $1 million.
Transactions are flagged when there are mismatches between IP and billing locations, VPN usage, or activity originating from high-risk regions.
Device fingerprinting further strengthens security by creating unique profiles based on device characteristics like models, operating systems, browser settings, and hardware configurations. AI systems monitor for suspicious signs such as app cloners, emulators, or VPN usage that could indicate fraud.
Additionally, behavioral biometrics - such as keystroke patterns, mouse movements, and mobile interaction habits - add a personalized layer of verification. AI learns these behaviors to detect when an account is being accessed by someone other than the legitimate user. For example, in March 2025, J.P. Morgan reported that AI-driven payment validation reduced account rejection rates by 15–20%, cutting fraud levels while improving the customer experience.
When multiple red flags align - like a new device, an unusual location, and deviations in user behavior - AI can take proactive measures, such as blocking transactions or requiring extra authentication before processing payments.
