Credit cards have a printed or embossed bank card number complying with the ISO/IEC 7812 numbering standard. The prefix of the card number, called the bank identification number (known in the industry as BIN ), is the sequence of digits at the beginning of the number that determines the bank to which the credit card number belongs. These is the first six digits for MasterCard and Visa cards. The next nine digits are the personal account number, and the last digit is a validity check code.

If the billed amount is not paid in full, the credit issuer charges interest on the unpaid balance (usually at a much higher rate than most other forms of credit). In addition, if the cardholder fails to make at least the minimum payment by the due date, the issuer may levy a late fee or other penalties.
