Hello Kumar,

M24SR can be protected by password in read or writes by following the following steps:

Locking an NDEF file :

The RF or IÂ²C host executes this procedure to protect an NDEF file.

1.Select the NDEF Tag Application

2. Check the right access provided by the CC file

3. Select the NDEF file

4. Transmit the NDEF file Write password by using the Verify command

5. Lock the NDEF file by sending the Enable verification command.
