NFC tags are passive, meaning they don't have any power source. Instead, they literally draw power from the device that reads them, thanks to .This is typically either. repeated deactivation and re-activation cycles, repeatedly reading a certain memory area, or. some other ping-pong command sequence. that allows the NFC stack to find out if the tag is still responsive. Only if the presence check fails, Android will switch off the HF .
Tag myTag = (Tag) intent.getParcelableExtra(NfcAdapter.EXTRA_TAG); Log.i("tag ID", myTag.getId().toString()); This gives me an ID like "[B@40521c40" but this ID changes every read.
