Track data is the information encoded and stored on two tracks located within the magnetic stripe on the back of a credit card (debit card, gift card, etc). There are three tracks on the magstripe (magnetic strip on the back of a credit card).

Each track is .110-inch wide. The ISO/IEC standard 7811, which is used by banks, specifies:

Track one is 210 bits per inch (bpi), and holds 79 six-bit plus parity bit read-only characters.

Track two is 75 bpi, and holds 40 four-bit plus parity bit characters.

Track three is 210 bpi, and holds 107 four-bit plus parity bit characters.

Your credit card typically uses only tracks one and two. Track three is a read/write track (that includes an encrypted PIN, country code, currency units, amount authorized), but its usage is not standardized among banks.
