read only tag
Asked by

How to change permission from read/write to read only tag. I use tags type 2.
I found this at "Type 2 tag Operation Specification":
Transitions from READ/WRITE to READ-ONLY
[RQ_T2T_NDA_026] To perform the transition from READ/WRITE to READ-ONLY, the
NFC Forum Device SHALL set Byte 3 of the CC to 0Fh and all lock bits to 1b (including static
and possible dynamic lock bits). To set bits and bytes, the NFC Forum Device MAY use one or
more WRITE commands.
But i can't understand what exactly do to perform this transition. Please help me through an example...
Thanks
