Hello hackers!
I was reviewing the specsheet for the NExT’s T5577 and it shows that the lock bits (stored at bit 0 of each block) are fully intact and functional. There is also no mention of T5577 lock protection on the NExT product page like there is for the NTAG216.
So my question is, are the lock bits actually functional on the T5577 chip inside an NExT?
And a follow-up question, what is the mechanism for disabling the lock bits for the NTAG216? Is it a modified chip or is it a password protection on the lock bit pages? Just a curiosity, as I saw the lock bits were fully functional in the NTAG specsheet too.
