The Magstripe is recorded with information for automation of transactions.

Track 1, developed by the International Air Transportation Association (IATA), contains alphanumeric information for automation of airline ticketing or other transactions where a reservation database is accessed.

Track 2, developed by the American Bankers Association (ABA), contains numeric information for automation of financial transactions. This track of information is also used by most systems that require an identification number and a minimum of other control information.

Track 3, developed by the Thrift Industry, contains information, some of which is intended to be updated (re-recorded) with each transaction (e.g. Cash Dispensers that operate "off-line").
