New Three-Digit Value
An important new security feature
for card-not-present transactions now appears on the back of
most Visa/Master 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 is printed on the signature panel on
the back of Visa/Master cards immediately following the Visa
card account number.
The CVV2 value helps validate
The customer has a Visa/Master card in his/her possession.
The card account is legitimate.
CVV2 is printed only on the back of Visa/Master cards — it is
not contained in the magnetic stripe information, nor does it
appear on sales receipts.
*American Express do not have a CVV2 Code.
