I just got the xNT NFC Tag [NTAG216] implanted successfully. I can read the UID ok with the DT KBR1 just fine. I also ran the password set with the DT app. I can read it just fine with the NFC Tools app (
When i first got my implant, it was locked. The lock bytes were set to address 0 (meaning anything past that was password protected and couldn’t be written to).
The default password is ffffffff
I had to use the Dangerous NFC Android app to set the lock bytes to an address that allowed me to wrote to the chip.
