8.5.15 Command: Set tag protection
NOTE
The command code for fast processing with the loop counter is 0x2103 (hex.) or
8451 (dec.).
The Set tag protection command defines password protection for the tag with a direct com-
mand. For this it has to be specified whether a write protection or a read protection should be
set and the area of the tag to which the password applies. Protection for all areas is defined
with one command. When sending the command only one tag can be located in the detection
range of the read/write head.
Write protection is always also contained in a read protection.
NOTE
A write protection for UHF tags cannot be undone.
