Usually only track1 and track2 are needed to exploit the ATM card. The first thing on track to is the PRIMARY ACCOUNT NUMBER (PAN). Track 2 is the main operational track for online use.

The ATM itself could have the ability to rewrite this track to update information. (And usually anything I describe in track 2). It contains security information as your daily limit, limit left, last access, account number, and expiration date. This track is also used with the new airline auto check in (PSA, American, etc) There are some glitches in how things are ordered so occasionally you do get "Greetings Bill Smith Dr." but such is life. This is the track that is used when the ATM greets you by name. It contains your name and usually your account number. There are actually up to three tracks on a card.
