Example Magnetic Card Number:

;1444000024003?

Generally the first 4 digits mean something like the location and then the rest is the identification number. You have to have all this data (Excluding the sentinels) on the account. Login Cards would generally look something like:

%4467?

TRACK_1_START_SENTINEL = '%';

TRACK_1_END_SENTINEL = '?';

TRACK_2_START_SENTINEL = ';';

TRACK_2_END_SENTINEL = '?';

TRACK_3_START_SENTINEL = '+';

TRACK_3_END_SENTINEL = '?'
