Disable Verification Requirement command

The Disable Requirement command deactivates the protection by password of the NDEF

file. When this command is successful, the read or write access to the NDEF file is granted

without security requirements. It can be performed only if the security status satisfies the

security attributes for this command.

Before sending this command, the verify command with the correct NDEF write password

shall be issued. Thus, this command changes the access right of the NDEF file.

This command can update the right access of the NDEF file by writing into the EEPROM. In

this case, the response timing will be around 6 ms.
