8.5.13 Command: Set read/write head password
The Set read/write head password command directly sets a password for write access, read
access or a kill command in the tag. The password is stored temporarily in the memory of the
read/write head. After the voltage of the read/write head is reset, the password must be set
again in the read/write head. With UHF applications, the password is stored in the memory of
the interface.
