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

Good luck on that one, dude.

95% of the people on this board have never even touched e-commerce, never mind as a developer.

The only thing I know about is that there's a Base24 central banking network that processes them all and sends back responses. I don't know where the network is or who to contact, though.

Sounds like you're on your own on this one.
