Maybe you know how E-commerce works and How the EAN/GTIN or ASIN works. ASIN is the Amazon barcode. The others as far i know are global standards. Maybe there are others in china or south America. If there are big others, even better.
With thinking about it, I mean we could store that info on chain and make it also unique and worldwide accessible via QR code or even barcode. In case you don't know, you need to buy in 1000 packs or expensive single ones.
So it's a huge market.
The sense behind Barcode is make every item scalable around the globe with the system. So something like Blockchain in centralized and expensive.
How could it work?
The same way like buy a EAN. Copy and paste on blockchain with Code generation + unique QR code.
But wait, with the new updates from 
Important about Barcode is, that they need to be unique for each item. I think a Blockchain solution on hive could work really well, because web-based + possible visualization.
Code could be encrypted in numbers, to make it "unchangeable".
Will this bring hive to the moon? Nope.
But with more users and a standard implemented that could work in theory, it's likely some will use it and it scales with time.
Special if HBD becomes a useable currency. For international commerce, it could be a barrier-free information transfer that is pretty manipulation resistant.
In case you don't know, there are some shady things possible with product identifying.
Special it could be "free" on hive.
Maybe something someone wants to build and earn nothing out of it. Maybe it never gets used.
But in general, a useful thing if people would use it.
