What kind of systems are you talking about, meaning what kinds of clients and servers? Is this about security within one system, or about communication between them?

You need to be more specific. A lot more specific, its a huge area.

I wrote security and encryption software for CyberCash, we invented Internet commerce. Seriously. The security was fine, the business went boom in the dot.bomb.

What do you mean by payment system? If you are actually writing a payment system, like CyberCash, or PayPal, then this is not the place to ask.

If you mean you want to setup a webstore and accept credit cards, that is a well understood problem. And you start by using HTTPS to protect data in transit.
