to be honest, NFC is solely a re-packaged version of contactless chips...nothing more than that, the only difference is that the readers are linked to the phone and is further processed from there...though in theory, any phone with USB OTG enabled should be able to install and use contactless readers, provided it has the drivers for it...

but as for, it being able to read the MyKad, i am somewhat skeptical about it, as I believe the MyKad is solely a contact chip..the MyKad has TnG on it, high chance it is reading that instead..

actually it is possible and the infrastructure is already there..just that users do not have access to the security chip only.

but i also suspecting it might be possible if we put the NFC tag into a read state and just wait for the incoming APDU and then process it. so if we write an "00 00 00 00 00", it should put the NFC reader into read and wait for a response APDU and then we hijack it from there on..plus since NFC is all about us sending our own APDU and processing it ourselves, it might be possible.

but you would need to write a lot of codes to enable it to emulate a tag.

that communication can be made through software also..not really complex in theory..
if we break it down, its all APDU commands..
