Change Reference Data command
The Change Reference Data command replaces the read or write password related to the
NDEF files previously selected. 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 reference data of the NDEF file.
Table 36 defines the Change Reference Data command.
