Visa and MasterCard credit/debit cards have the three-digit value printed on the signature panel on the back of the card immediately following the card account number. The back panel of most Visa/MasterCard cards contain the full 16-digit account number, followed by the CVV/CVC code. Some banks, though, only show the last four digits of the account number followed by the code.
American Express cards have a four-digit non-embossed code located on the front of the card.
