Hi there,
I used to work as an epayment developer/consultant in an environment that every thing was domestic and local. Actually I had to develope epayment solutions from the scratch using ISO8583, ISO7816, EMV and smartcard standards and protocols. But all of those protocols and standards are talking to a server which I had developed and all of them were smart card transactions.
Now I am envolved in an international magnetic card system where I should authorize transactions requested from cards issued by different issuers and more over from different countries.
I would like to know more about the way credit/debit transactions are authorized and processed internationally as well as payment gateways procedures and standards.
I would appreciate any answer that pushes me forward.
Regards
