Not commenting directly on your assessment of the state of PoS systems, but how does a software vendor (not OS or sys admin) protect against targeted malware that is able to get access rights to your RAM space from scanning for well known track signatures?

Personally I believe that the current credit card system is broken and needs a significant change, but this is a very difficult process.
