MR350MKII’s Smart Card reader can support T=0 and T=1 protocol. Users can directly use this 

system function call to develop their application. Actually, system function only provides 

primary command to access and control Smart Card reader. User should know detail control 

register and data structure level when they directly use system function call to write their 

application program.   

 

Although, there are variety of smart cards on the market to provide a design reference, Unitech 

develops an Smart Card library to provide all MPCOS-EMV command set, so user can directly 

use those function libraries to develop their application program without knowing detailed low 

level control register and data structure. Some of command sets (in our Smart Card function 

library) are following ISO 7816 standard, so they are not dedicated for GEMPLUS 

MPCOS-EMV. So, users can also use part of this Smart Card library to develop their application 

program for other format card. In chapter 3, we will mark every function library to tell user 

whether it is standard command or dedicated for GEMPLUS.
