8.5.12 Command: Set tag password
NOTE
The command code for fast processing with the loop counter is 0x2102 (hex.) or
8450 (dec.).
The Set tag password command sets a password in the tag. When sending the command only
one tag can be located in the detection range of the read/write head. After the password is
sent, other commands (e.g.
Set tag protection ) can be sent to the tag. The Set tag password
command prevents a Kill password from being set in the tag.
