consider digimarc barcode too. qr code is nice, but nicer is it if you even not see it.

I'm glad to see this. Switching to a new standard barcode format that can hold more data and enable better tracking of physical consumer goods seems like the sort of thing that will have a large number of small benefits pervasively in the economy, one of the many small improvements of human technological civilization that in the aggregate results in a better world today than in the past.

I also like the aesthetics of QR codes better than traditional barcodes. They do kind of invoke the look of a Go board partway through a game, which is more visually interesting than the boring straight lines of the traditional barcode.

We must create a barcode reservation to preseve the last of the species before they go extinct!

Hopefully they can reproduce and ensure the survival of their species.

JAB Code (color bar code) can fit more data into the same space: https://jabcode.org/

What a bad piece. Optical is obsolete. Decathlon (here in France at least) has RFID on all their products, they're used as anti-theft, automatic tilling: you just put them in a box at the register and it knows what it is (also kills the chips once paid) and very likely they're used all along the logistic chain.

They mention QR code being a link and companies having to store data on their side.

Surely the actual data will be stored in the QR code and available offline

At family mart in China, some of the pastries are in bags with a QR code and a bar code. If it accidentally scans the QR code the self checkout (not in English) goes into a weird mode and I have to get help. So I just learned to cover the QR code for any packaging that had both it and a bar code on the same side.
