American Express Card Holders The Card Identification # is
the 4 digit, non-embossed number printed above your account number on the
face of your card. This number is recorded as an additional security
precaution.
Private Payment User? Please use the CID from your issued American
Express Card.
If your AMEX account number does not have a plastic card associated
with it, then you do not have a Card Identification #. In this case, you
should enter the last 4 digits of your AMEX account number in the Card
Identification # field in order for your transaction to be processed.

Visa, MasterCard and Discover Card Holders CVV2/CVC2: A new Three-Digit Value
An important new security feature for card-not present transactions now
appears on the back of most Visa cards. This new feature is a three-digit
value which provides a cryptographic check of the information embossed on
the card.
CVV2/CVC2 Location
The three-digit value is printed on the signature panel on the back of
Visa, MasterCard and Discover cards immediately following the card account number.
The CVV2/CVC2 value helps validate two things:
- The Customer has the credit card in his/her possession.
- The Card account is legitimate.
CVV2/CVC2 is printed only on the back of these cards--it is not contained in
the magnetic stripe information, nor does it appear on sales receipts. |
