Card Code (CVV2 - CVC2 - CID) is a three-digit security code that is printed on credit cards. The value appears in reverse italic at the top of the signature panel on the back of the card (Visa, MasterCard, Discover), or on the front of the card just above the end of the credit card number (American Express). These additional numbers provide an extra measure of security against unauthorized credit card transactions. The credit card would need to be present for the purchaser to know the Card Code number, as it is not stored on any system outside of the credit card issuer. The Payment Gateway allows you to customize your account so that the system rejects transactions where the Card Code provided by the cardholder is invalid. By using Card Code verification, you are able to make a more informed decision about whether to accept a particular credit card transaction.
