Tokenization is a method for protecting card data by substituting a card's Primary Account Number (PAN) with a unique, randomly generated sequence of numbers, alphanumeric characters, or a combination of a truncated PAN and a random alphanumeric sequence.
Tokenization is currently in standards definition in ANSI X9 as X9.119 Part 2. X9 is responsible for the industry standards for financial cryptography and data protection including payment card PIN management, credit and debit card encryption and related technologies and processes.
