Credit Card Glossary: Terms and Definitions
In fraud detection, a “false positive” occurs when something innocent is wrongly deemed suspicious. Credit card holders encounter false positives most often occurs when a cardholder accidentally trips the card issuer’s fraud detection system. Card issuers have developed sophisticated, automated fraud detection systems that work by detecting activities and patterns associated with fraud, but these systems don’t work perfectly. False positives can cause a cardholder’s transaction to be denied or an account locked down.
