Credit Card Validation Value
What is the CVV?
CVV stands for Credit card Validation (or Verification) Value. Visa, MasterCard, American Express and Discover all have a version of the CVV to reduce merchant risk in Card-Not-Present transactions (like Internet, telephone, or mail-order). The CVV code adds assurance that the consumer placing the order has access or physical possession of the credit card itself in order to use the CVV code.
The CVV is a 3 or 4 digit code embossed or imprinted on the reverse side of Visa, MasterCard and Discover cards and on the front of American Express cards. The CVV is an important layer of security to help you reduce your risks in accepting Card-Not-Present transactions and may be required or recommended by your payment processor or merchant bank.
CVV is currently supported only for Visa, MasterCard, American Express and Discover.
