Start sentinel ó one character (generally ';')

number printed on the front of the card.
Separator ó one char (generally '=')
Expiration date ó four characters in the form YYMM.
Service code ó three digits. The first digit specifies the interchange rules, the second specifies
authorisation processing and the third specifies the range of services
Discretionary data ó as in track one
End sentinel ó one character (generally '?')
Longitudinal redundancy check (LRC) ó it is one character and a validity character calculated from
other data on the track.
Most reader devices do not return this value when the card is swiped to the presentation layer, and
use it only to verify the input internally to the reader.
