8.8.20 Command: Query HF tag protection status
NOTE
The command is only available for applications with HF tags and the HF tags
TW-R…-M-B146.
The Get HF tag protection status command queries with a direct command whether a specific
area of the tag is password protected. When sending the command only one tag can be loc-
ated in the detection range of the read/write head.
The password function is only available in HF applications in single-tag mode. An error message
is output with multitag applications. For troubleshooting set the
HF: multitag mode parameter
to 0 : Multitag mode off .
