POS Subsystem is split into reader, kernel and entry point. Download from EMVCo website the complete specification and understant what is expected from entrypoint and kernel perspectices. There are 9 in total

  • architecture(1)
  • Entry Point specification(1)
  • Kernel specification for each( 7, one for each payment scheme ).

Go through 1, 2 and the relavant kernel spec from third.
