Hi,

Does anybody have any information on the exact protocol & data format / sequence used by Credit Card terminals (like Verifone, Hypercom, etc.) to talk to the bank / verification server ?

I know that the link is set up on a low speed (V.22 or V.23) dial-up connection. I have also learnt that the basic method is a Synchronous protocol. I need to know the exact sequence used to establish the link, send the card number, amt, etc for verification.

Any help in this regard would be highly appreciated.

Regards,

Smokey
