for internet transactions. It consists of requiring a card holder to enter the CVV2 number in at transaction time
to verify that the card is on hand.
Visa or MasterCard:
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.
This number is printed on your MasterCard or Visa cards in the signature area of the back of the card. (it is the
last 3 digits AFTER the credit card number in the signature area of the card).
American Express:
American Express cards show the cvv2 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.
