What is CVV Fraud Detection?
CVV fraud detection systems analyze the CVV, expiration date, and other card details to confirm transactions authenticity. If discrepancies are found, the system flags the transaction for review.
Key CVV Fraud Detection Rules
- Check CVV match: The system compares the CVV entered with the one on the card. A mismatch raises red flags.
- Validate card expiration: Expired cards are more susceptible to fraud. Systems reject transactions on expired cards.
- Monitor transaction behavior: Unusual spending patterns, such as high-value purchases or purchases in different countries, trigger alerts.
