The credit card swipers send the entire transaction in for both approval and reporting. I'd imagine that the account number, merchant number, and transaction amount are all there, since that's all needed. Whether or not they encrypt the data I don't know.
I believe modern card readers for at least MC/Visa use some form of encryption, but for backwards compatibility the central offices also work unencrypted. In the hotel I used to work in, the card reader certainly didn't encrypt. -j -- "Blah Blah Blah" ___________________________________________________________________ Jamie Lawrence <jamiel@sybase.com>
