the old card reader hardware read only track 2 (numeric only)

which contains a start char, the card number, a seperator, and then
other junk and a stop char.

the other junk tends to be stuff like expiry dates and isnt in 
any predicatable format that i could see.

so if you take only the stuff between the start char and the seperator
then you can cope with any card type.

i get the impression that the current card reader will read track 1 as well
and possibly track 3.  it must indicate somehow which is which, probably 
a control code, so youll need to investigate carefully.
