What is CVV Authentication?
CVV authentication is a security measure used by online merchants to verify the legitimacy of a credit card transaction. It involves checking the Card Verification Value (CVV) printed on the back of the card, which is a three or four-digit code.
How CVV Authentication Works
- The customer enters their credit card information, including the CVV, during the checkout process.
- The merchant's system sends the CVV to the card issuer's server for verification.
- The card issuer checks if the CVV matches the one on file for the card.
- If the CVV is correct, the transaction is authorized. If not, the transaction is declined.
Importance of CVV Authentication
CVV authentication plays a crucial role in preventing fraud and unauthorized transactions. It adds an extra layer of security, ensuring that the person making the purchase is in possession of the physical card.
