Bank Card Number
Payment card numbers are found on payment cards, such as credit cards and debit cards. They have a certain amount of internal structure and share a common numbering scheme. Bank card numbers are allocated in accordance with ISO/IEC 7812. The bank card number merely identifies the card, which is then electronically associated with a particular cardholder and also to the cardholder's designated bank account/s.
An ISO/IEC 7812 number is typically 16 digits in length. It consists of:
- a six-digit Issuer Identification Number (IIN), the first digit of which is the Major Industry Identifier (MII),
- a variable length (up to 12 digits) individual account identifier,
- a single check digit calculated using the Luhn algorithm.
The term "Issuer Identification Number" (IIN) replaces the previously used "Bank Identification Number" (BIN). See ISO/IEC 7812 for more information.

Famous quotes containing the words bank, card and/or number:
“A self is, by its very essence, a being with a past. One must look lengthwise backwards in the stream of time in order to see the self, or its shadow, now moving with the stream, now eddying in the currents from bank to bank of its channel, and now strenuously straining onwards in the pursuit of its chosen good.”
—Josiah Royce (1855–1916)
“The Card Catalogue: “See also” leads into the wilderness.”
—Mason Cooley (b. 1927)
“In the multitude of middle-aged men who go about their vocations in a daily course determined for them much in the same way as the tie of their cravats, there is always a good number who once meant to shape their own deeds and alter the world a little.”
—George Eliot [Mary Ann (or Marian)
