Card number (PAN)

Every payment card (be it a debit, credit, gift, or a similar card) has a unique number associated with it. This number is usually printed on the card and required to uniquely identify this card and to refer to it in every transaction.

The whole card number is called Primary Account Number (PAN), and the first six digits of it are also called as the Bank Identification Number (BIN).

Also, a card may contain a card security code, which, along with the card number, can be used in card-not-present transactions.
