Lock
This area is not displayed if you have selected the modulation scheme "65 - ISO 18000-6B".
In the "Lock" area, you can protect or unlock the memory areas (banks) as well as the
access and kill password of the selected transponder. Select the "Permanent" check box to
make the setting irreversible. Click the "Apply" button to transfer the settings to the
transponder. To enable/disable protection, you need to enter the access password in the
"Password" input box.
NOTICE
Read/write protection of the passwords
Note that passwords that are read/write protected can no longer be read out. We
recommend that you note down the password.
Kill
This area is not displayed if you have selected the modulation scheme "65 - ISO 18000-6B".
In the "Kill" area, you can 'destroy' the entire memory of the transponder. Following a
successful "kill", the transponder can no longer be identified by any RFID reader and is
therefore no longer usable. To "destroy" the transponder, click the "Execute" button. To
destroy the transponder, you need to enter the kill password in the "Password" input box.
Explanation of the Lock command
In the factory setting, UHF transponders are not protected by passwords in other words they
are in the "open status". The memory banks "0" (kill / access password), "1" (EPC) and "3"
(USER) can be modified with a write command. Memory bank "2" (TID) can normally not be
changed since this is already locked by the manufacturer.
Some use cases, however require that writing is checked or completely prevented. The
"Lock" command is used for this purpose. With this, you can lock individual or multiple
memory areas. To be able to lock memory areas, you need to change the transponder to the
"protected status" (access password ≠ 00000000). You create the access password using
the predefined tag fields and can edit this using the "Read/write" area in this menu.
After you have changed the access password, you can still access the memory areas with
the default password. To access the memory areas only with the access password, enable
the read/write protection of the relevant memory area.
