Re: GP Card Manager Failed - PyAPDU Tool

perhapse, the card don't install the card manager. so you select the card manager failed and the other command(eg: init update ) will be failure,too.
You should study some specification. eg: GP special and the SCP(secure channel protocol) in the GP special.
