    RW420 - Smart Card Reader Protocol

    Javier Linan



      I need to change the protocol to T1 in the smart card reader of printer.

      Is it possible to change the protocol from T0 to T1?


      I am trying to do it the following way :


      Command PPS :

      byte[] PST_SELECT_PROTOCOL = { (byte)0xFF, (byte)0x01 , (byte)0xFE };

      Response of printer : 1521 where 21 is Too short APDU


      can anybody help me? , by the way i'm working Android application.


      Thank you!
