Speed up and improve fraud detection for card payments

Target Audience

Banks and financial institutions, insurances, merchants

Challenge

Fraudsters steal millions of payment card numbers through malware, spyware, and card skimming, then sell partial card data on illegal websites. Traditional detection methods struggled to identify compromised cards quickly enough, and banks had limited ability to predict which cards were at risk before fraud occurred.

Solution Approach

Mastercard built Decision Intelligence Pro, trained on data from 125 billion annual transactions. The system scans transaction data to identify fraud patterns, then uses generative AI to predict full 16-digit card numbers from partial information provided in dark-market-auctions, enabling preemptive blocking.

Value Add

The technology doubled the detection rate of compromised cards, reduced false positives by up to 200%, and increased the speed of identifying at-risk merchants by 300%. The system processes decisions in just 50 milliseconds. Mastercard's Consumer Fraud Risk solution reduced UK APP fraud value by 12% since launch in 2023.
