Real Time Fraud Monitoring

Intelligence is our best defense. The instant a merchant processes your card, Visa goes to work preventing fraud. We use a detection system to scan thousands of transactions per second. We look for subtle changes in spending patterns that could indicate fraud. If something's amiss—a mismatched address, an unusually large purchase, or transaction far from home—we respond immediately.
