To help reduce fraud in the card-not-present environment, credit card companies have introduced a card code program. Visa calls this code Card Verification Value (CVV); MasterCard calls it Card Validation Code (CVC); Discover calls it Card ID (CID). The card code is a three- or four- digit security code that is printed on the back of cards. The number typically appears at the end of the signature panel.
The 4- digit Commonwealth Bank American ExpressÂ® Card code is located on the front of the card, above the card number on the right hand side. With a MasterCardÂ® or Visa card, the 3- digit number is located in the signature panel on the back of the card. The 3 or 4 digit code uniquely identifies that a card number quoted to a merchant was obtained from a genuine credit card therefore providing merchants with an increased level of protection against fraud.
