you're looking for PCI (Payment Card Industry) information? I don't know of any single location that will walk through it. I know people who've worked for a processor and it's a huge, complicated, heavily regulated, expensive to get into, but lucrative industry.

Possibly research through the PCI standards (and wikipedia for PCI and following the references) will get you enough cross-references to put together what you're looking for, or at least tell you if what you're looking for exists out in the normal world. (as opposed to being behind consultant paywalls)

Yes, exactly this. OK, so I will start with doing the research through the PCI standards. Thanks!
