Thanks for the reply.
This tells me the identifier part of a universal item identification system is already finished.
This new UPC has the advantage that it could be used to identify individual items in a series thereby actually being a Unique Item Identifier, not just a product line identifier as the UPC is. By using a Cardano address QR code or a QR code paired with some form of chip that makes the address available for reading via NFC or similar technology, a Unique Item Identifier could be “implanted” on every product made anywhere in the world.
Any item without a QR/chip pair corresponding to a Cardano address would simply be considered an undocumented product and that fact would become part of its history once a new address was assigned to it since we can now have both IDs for any item and short histories for any item. This would likely cause a significant drop in the value of the item and would be huge incentive toward not vandalizing the QR/chip pair.
I don’t think I have seen a serious effort at trying to get this implementation in motion on any crypto currency though the benefit seems very interesting. The ability to be certain that someone is the rightful owner of an item would be as simple as being able to read either part of the QR/chip pair.
The catch is that this system would be most useful and honored if implemented for the purpose of tracking the most expensive assets most people have but those assets are the ones people have the least incentive to track with a new and unknown protocol. Interesting problem.
Is there anyone working of anything of this nature?
