Hello,

in case anyone is interested I am working on a magnetic card decoder
using a PIC.  I have a card reader that gives me raw data from track 2
of the card, and I am using ISO7811/2-1985 (BS 7106:Part 2:1989) as my
specification for decoding this data.  Since the PICLIST has a lot of
'Help, I'm stuck' messages I thought I would shine a little ray of hope
with a 'Hey, it's working just fine' message. So far I have spent about
2 hours on it and it looks good.  I can see the data on the card, and
can detect the start and end markers.  I think I might run into problems
with the amount of RAM for buffering the data (I am using an '84), but
I'll see.  I want to read the number off the card, and either display it
on an LCD, or send it serially to somewhere (!).  Alternatively I could
hook up a serial EEPROM, and store one or more card numbers in it and
use it as a simple access control system.

I am not sure what I shall actually use this for, so at the moment it is
just an exercise.  More news as it's made.

Andy
