After generating a PIN, it will need to be activated (used to unlock) before it expires.
The status "To Be Activated" means that PIN is still within the activation period. This status may still show even after you have activated the PIN, as the status needs to be updated via Update Logs function.
The status "To Be Updated" means that the PIN's activation period is over. If the PIN was not activated before this status appeared, the PIN is expired. In order to view the updated status of the PIN, you will need to Update Logs.
If you have successfully used the PIN and updated the logs, you will see either "In Use" or "Expired", depending on the PIN type.
