Understanding CVV Validation
CVV validation is a crucial step in ensuring the security of online transactions. It's a three or four-digit code found on the back of your credit card. This code serves as an additional layer of security to verify that the cardholder is in possession of the physical card.
How CVV Validation Works
During the transaction process, the CVV code is sent along with the card number, expiration date, and other details. The payment processor then uses the CVV to verify that the transaction is being made by the actual cardholder. If the CVV does not match the one on file with the card issuer, the transaction is likely to be flagged as fraudulent.
