Best Practice for Writing a POS System

Question

Answer 1

From just a quick browse the MS point-of-sale system is based on Window Embedded which is really just a way to get a lower cost per unit and smaller Windows OS license. It seems there are some APIs specific to POS, but you seem to want to roll your own, you'll still probably want to use Windows Embedded in some way. Security will probably be job 1.
