PAYMENT ACCOUNT TOKENIZATION METHOD

摘要

A method includes receiving a bank identification number (BIN) that defines a range of indicator numbers, and generating a plurality of primary account numbers (PANs) that start with that BIN. The method further includes generating a plurality of tokens that start with the same BIN. The PANs may have a prescribed length in digits that differs from the prescribed length in digits for the tokens. Thus tokens can be distinguished from PANs based on length in digits, even though the PANs and tokens may be formed with the same BIN.
