I am not even sure whether this can be done or not!
Searched for it but couldn't find much help on the subject So here I am. Is RFID programming for reading tags possible for Android OS? Can I have RFID enabled on my phone instead of a keycard?
Thanks in advance, any help on the subject is appreciated.
RFID in Android phone is achieved by NFC.
You can write & read tags of various kinds.
