CVV Definition.
Card security code (CVV2/CVC2): 3 digits on the back of the card (4 on the front for American Express), checked by the issuer on remote payments. It proves physical possession of the card at the time of entry. PCI DSS strictly prohibits storing it after authorization, even encrypted, and doing so is one of the most frequently penalized compliance failures.
