I am the creator of https://www.closient.com/ - a GS1 Digital Link Resolver (still building it, be gentle).
I have been deep into this space for a fair bit of time now. The real power is in Recalls and Return Fraud. There a ton of other nice things that this will empower of course. AMA - I will do my best to answer.
Not advertising - just trying to get the word out on 2D codes and RFID and what they provide consumers.
For those saying "Why not something else?" - it comes down to adoption - QR was just the more popular winner. While the register/till is where most of the scanning is happening the QR is just a normal URL and consumer can scan them.
At a fundamental level, if the website isn't the product, the product has been public-facing and/or created post-2025, and it's not coming from a multi-million funded tech business, I wouldn't dock points for a slopped website — let the team focus on maintaining and using skills related to the actual product, while still having a working website. Even if the visual and textual tone may be off-putting, a decent-looking slopped website is better than no website, I prefer being able to discover and interact with them at all than not.
Just don't bury the core concept of your product in marketing-slop on your website (this site is certainly pushing that limit for me).
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.
As I understand it, The key bits of data are in the QR code, they are just encoded as a URL - a highly structured URL that point of sale systems can decode without visiting the URL.
Doing it this way means the QR code is directly usable by consumers to get to a product info / marketing page, and directly usable by the POS systems.
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.
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.
Merchandise point-of-sales tags isn't the only use of barcode or QR codes. Hospitals aren't going to start putting RFID for all equipment, files, and patients.
I think this is great! i've long wanted a future where i can stock my fridge and cupboards with goods and scan the barcodes in and be tracking what their expirations are to better manage when i need to restock or throw things out

Interesting, but your website looks completely AI-slopped.

They aren't. Sage.
JAB Code (color bar code) can fit more data into the same space: https://jabcode.org/
I love how the website shows examples and comparisons with the codes it claims to be better than.
where?
It's not easy to print in color on some products (e.g. products that use thermal printer labels).

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

Edit: I looked it up. An example URL:
https://example.com/01/09521207311511/21/1234ABDE1235
01 is a marker before the traditional barcode.
21 is a marker before the serial number.
There seems to be many other codes like 17 (expiry date) and 10 (batch number).

Putting a chip on everything sounds wasteful and worse for the environment than a printed piece of paper. Not the right direction to go in.
Decathlon does it in every country, not just France. Same with Uniqlo and a few others, but it's still only very large chains that can afford it
Uniqlo does it in the states now. It’s the first time I encountered it though (well, except for Uniqlo in Japan, even Muji is still using bar codes).
Merchandise point-of-sales tags isn't the only use of barcode or QR codes. Hospitals aren't going to start putting RFID for all equipment, files, and patients.
I thought that was exactly one of things RFID was used for?
Perhaps not for files, but definitely for equipment.
I am quite sure they still use optical on the German shops.
Nope, at least the Berlin shop is on RFID on all products.
Yeah, unless they changed on NRW shop on my area since August.
My diving mask and backpack certainly went through optical.
Too pricey for food, it’s cheaper to print.
Printed Chipless RFID Will solve that problem if the tech really works.

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.
An infinitely wide but infinitely short world should suffice.
consider digimarc barcode too. qr code is nice, but nicer is it if you even not see it.
How to i keep my thumb off it during scanning?
