Visa Improves Fraud Detection With Deep Learning

Visa's head of predictive fraud intelligence John Munn told PYMNTS in a recent interview that fraudsters increasingly use AI to probe defenses, making static rules ineffective. He said Visa uses deep learning models trained on global payments data to detect subtle behavioral deviations, delivering 15%–20% higher authorization rates while reducing false positives. Continuous, pre-authorization monitoring and model updates are essential, he advised.
