2.3.1 Locking The NFC Tags

The NFC tags can be “locked” or set to a restricted mode once encoded / written after which they can never be overwritten or edited in any way again. The software has a lock-mode which can be enabled to lock the tags once written so those tags can not be reused, tampered with or overwritten by anyone after the first write. It is important to note that this lock-mode is permanent and a tag can not be unlocked or made writable again once locked so if you’re testing with the tags and reusing them to encode different URLs, you may want to keep the settings on “Normal Mode”. However, if you are encoding your tags for final production purposes and do not want anyone in future to be able to change the contents of the tag or overwrite them, then the “Lock Mode” is preferable. 

To set the configuration for locking NFC tags within the top menu options, select Settings->NFC Tag Locking Configuration.

This will bring up a pop up window with the Tag locking configuration. To enable the tags to be reused or overwritten after encoding / writing the tags, select the “Normal Mode” radio button option and click “Save”. To have the tags locked permanently so that they can not be overwritten once encoded / written, select the “Lock Mode” radio button option and click “Save”. If this option is selected, once the software writes to the tag, the tag lock settings will also be written to the tag and the NFC tag will no longer be writable or can not be edited by anyone going forward.
