ATRs contain no useful client-application information.  In fact two cards with 
completely different applications from two diffferent card manufacturers can 
have identical ATRs.  Security through obscurity don't you know.

        Yeah, I know how to get ATR out of it, but does it tells me what size 
it has? 
        ATR of my card is: 
        iso7816.c:99:iso7816_check_sw: Instruction code not supported or 
invalid 
        card-gpk.c:1703:gpk_get_info: Card returned error: Unsupported INS byte 
in APDU 
        3b:fd:94:00:00:81:31:20:43:80:31:80:65:b0:83:02:04:7e:83:00:90:00:b6 

        It seems that it has gemsafe applet on it, so only choise for me is 
        opensc, since 
        muscle supports only muscle applet, right?
