8.8.32 Command: Kill UHF tag
NOTE
The command is only available for UHF applications.
NOTE
The command code for rapid processing with the loop counter is 0x2200 (hex.) or
8704 (dec.).
The Kill UHF tag command makes the tag memory unusable. After a kill command, the tag can
neither be read nor written. A kill command cannot be reversed. A Kill password must be set
beforehand in order to execute a Kill command (see [}229]).
See description of the output data, p. [}105].

Length UID/EPC Enter UID or EPC size in bytes if a particular tag is to be
deleted. The UID or EPC must be defined in the write data
(start byte: 0). The function of the UID/EPC length is
dependent on the command used.
0: No entry of a UID/EPC for executing the command. Only
one tag can be located in the detection range of the read/
write device.
> 0: EPC length of the tag to be deleted if an EPC is present
in the write data
-1: NEXT mode: A tag is always only deleted if the UID/EPC is
different to the UID/EPC of the last read or written tag.
