the funny part is that while i worked at trintech i actually learned
more about credit card validation at itg. then again i had a working

eek! almost, but no. you emulate the terminal in software. all you have
to do is speak the protocol over the wire to the bank (or via a third
party which is really just a router - converting your stream carried
over ip to the same stream carried over x25 or whatever banks like).

it's what the terminal speaks to the bank. and i haven't a clue if
it's public (and therefore won't post it), but it's delightfully simple.
some fixed length fields followed by variable length fields (which are
seperated by field separators - man ascii).
then we have the protocol nortel's intelligent network uses (coupled
with a previous engineers convoluted use of classes[0]). whimper.
but that's for talking to some telco thing, it's not bank related.

yes, though i've only seen it being used to talk to uk banks. well,
i'm making some assumptions about ccvs[1], but yes i assume so.

it's really better to go with a company that has a relationship
with a bank. getting all this set up with the bank is an exercise
in frustration. of course i was doing it between late december 1999
and march 2000 which had the scary dates of 1/1/2000 and 29/2/2000 in
the period...
btw if anyone is still excited at this point i still have two dev
positions open. you can wallow in this stuff 40 hours a week.
imagine the sheer joy...

pointers after making your classes, chances are you have a design
flaw.
[1] am i the only one or does ccvs seem like a russion version
control system?
