\develop Simple SW to write on the IC Card/Server

I have IC cards or integrated chip cards that i needed to write on them. So, i am looking for simple SW and support for successful testing of this beta version design. My design and solution is almost the same as access control however it has its own different use cases. So, let’s assume that I need to create SW solution for access control within a hotel or company using IC card instead of normal RF or magnetic cards. How can a SW developer support me to develop SW to write on the Card and develop as well the back end server SW for verification and acknowledgment? No encryption required at this stage.
