After months of research and development, i was able to fully integrate mykad and mykid reader into my web application.
just for your information, as per my experience, only selected smartcard reader will be able to read MyKID. and these readers comes with another small card namely SAM license (like SIM card). Without this card the OS within MyKID will simply lock itself and will return "Invalid Command Class" despite any APDU sent to it.

In my experiment, i used the SCR21U reader and suceeded the test.
