My experience with CC scanners is:
Stand alone, in which case you're SOL.
Keyboard integration, in which case, the card number is "scanned", and
appears on the screen as if it had been typed in - i.e.: it's just a
time saver. In this case it would just appear in an appropriate place
in an HTML form.
Notes:
It's a good/recommended/required practice to encrypt a CC in the DB -
if so - you won't get a hit unless you've used the same encryption key
for all CCs and the request, which is a bad idea.
So:
Encrypt the CC normally, using a good mechanism, with unique
encryption keys/customer algorithm.
additionally encode the CC with a one way hash and store that as
well, with a DB index on the attribute. Then you can encode the CC from
the terminal example above and look for a match, which would return a
customer record with an encrypted CC, and the DB would not contain
visible CC data, should it happen to fall into the wrong hands.

Hi all,
I've got a potential client who has both a physical store and web
site, and would like to be able to scan a credit card, and if it's
available in his database get the customer data presented on screen
based on the scan (if it's not available, the customer will be
asked...). I would like to do all my database interfacing using WO.
I've never interfaced with a physical card scanner or POS software
before, and am wondering what the options are -- are there particular
packages you all would recommend? Has anyone used WebObjects in this
context?
Thanks!
