Card Security Code (CSC)

What is my Card Security Code?
The CSC (otherwise know as CVV2) is a authentication scheme established by credit card companies to further efforts towards reducing fraud for internet transactions. It consists of requiring a card holder to enter the CSC number in at transaction time to verify that the card is on hand.

If you are using a Visa or Mastercard, please provide the 3-digit verification number found on the back of your card. This is a non-embossed number printed on the signature panel on the back, immediately following the account number

American Express:
American Express cards show the CSC printed above and to the right of the imprinted card number on the front of the card. If you are using an American Express card, please provide the 4-digit verification number found on the front of your card. This is non-embossed.
