An important new security feature for card-not-present transactions now appears on the back of most credit cards. This new feature is a three-digit value which provides a cryptographic check of the information embossed on the card.
The CVV2 three-digit value for Visa/MasterCard, four-digit for Amex, is printed on the signature panel on the back of credit cards immediately following the card account number.
The CVV2 value helps validate two things:
The customer has their credit card in his/her possession. The card account is legitimate.
CVV2 is not contained in the magnetic stripe information, nor does it appear on sales receipts.
If a CVV2 code is entered for a transaction, the CVV2 Response Code will be displayed in the Transaction Center.
CVV2 (Card Verification Value) Response Codes
CVV2 is optional by default. You can set CVV2 to mandatory in the Global Options section of your management console.Edit
