android unlock screen using nfc

Question

I want to unlock the andorid screen when a tag is detected - based on the tag ID.

something like how com.biwota.cerbero is done. someone here has any experience or knows how this can be done. ? could you please point to the right directions perhaps ?

thank you Domnic

Answer 1

This is not possible, unfortunately. NFC polling is turned off when the screen is off or locked, since Android 4.0 ICS. Only with a custom ROM you can modify this behaviour.
