How to reconfigure so that an NTAG213 chip cannot be read when password protected

[tomtyrrell]

Hi,

I wonder if someone could help on how to reconfigure pages within the NTAG213 chip so that the chip cannot be read when password protected? 

Is this even possible with this type of chip?

Any feedback will be highly appreciated.

Best Regards

Tom.

For setting also read protection you should set page 2A (PWD_AUTH) first byte to 1, so you will enable the read and write protection.

Anyway, after doing it, I have experienced a problem: my application set read/write protection by a password but I can't remove the password protection after that. If I just apply write protection I can remove it without any problem.

Hope it helps

Eli.
