In contrast, the CVC2 code for Mastercard and the CVV2 code for Visa are specific generations of this security code, while American Express utilizes a four-digit CID (Card Identification Number) located on the front of the card. While both serve as card-not-present authentication tools, their official definitions, locations, and usage scenarios differ in subtle but significant ways.
CVC CVV Technical Definitions Compared: Key Differences Explained
Usage in Payment Gateways In the context of payment gateways, the terms are often mapped to specific transaction fields. The purpose of this generation process is to create a unique, non-reversible value that cannot be easily decrypted or duplicated.
When you enter this code during a purchase, the payment processor performs a mathematical check against the issuer’s records to confirm validity without exposing the actual generation secret. They are derived from the card’s primary account number (PAN), a secret key known only to the card issuer, and a specific transaction counter or timestamp.
CVC CVV Technical Definitions Compared
Defining the Core Security Elements CVC, which stands for Card Verification Code, is a generic term used to describe the cryptographic security code associated with a payment card. For instance, a gateway configured for "CVV" validation will look for the three-digit code common to Visa and Mastercard, regardless of whether the industry standard term is CVC or CVV.
