This is the number published on credit cards which is used to verify you are actually holding the card.
VISA / MasterCard / Maestro / Switch
On the signature strip there will be SEVEN digits. The first FOUR digits are the LAST FOUR on the front of the card. The next THREE are the Security Code.
American Express
On the front of the card, just above the card number is a FOUR digit number. This is the Security code on an AMEX. Out of interest, the back of the card has the full card number on the security strip but no security digits.
