There are other blockchain technologies that are being used for day-to-day operations.
VIDT - they are using blockchain to keep things authenticated and to protect them from being counterfeited
LTO - using the blockchain to verify things fast and efficient, eliminating fakes from the original
Simbachain - I am not familiar with their services but I remember them being used by USAF, Boeing, and other big organization in their operations.
cool concept on the timestamp from VIDT
there is this Layer 1 blockchain called 3DPass which does something similar by scanning. I even did a video on how accurately it could detect a fake/copycat with a small adaption to the 3D shape and it did very well

If you loose the password you can always literally recover it by scanning the item. Just make sure it's not stolen or your partners throws it in the garbage

DYOR but if you want more details check out the ANN thread
