GLOSSARY
Card Fraud
Unauthorized card use or theft of credentials to initiate transactions.
Card fraud includes stolen PANs, cloned cards, or account takeover leading to unauthorized payments. Card-not-present channels are more exposed than card-present because no physical chip/PIN is read.
Mitigations: network tokenization, device-bound wallets (Apple Pay, Google Pay), strong authentication, velocity controls, and robust fraud detection models.
