Set RFID Tag Password and Lock Tag
Description Use this command to define a password for a tag during writing.
With Gen 2 tags, you can lock a tag’s memory bank with an access password or define a kill
password that can be used to permanently disable the tag. If you do not set access or kill
passwords for a tag, the tag ignores any read or write commands that try to use these functions.
