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.
We have the technology to encode a short, plain human-readable description of an item into a 2D barcode, with born-on and/or sell-by dates, and/or things like serialization and/or lot codes, or other useful things.
Brevity is important; fields can have a standardized-but-flexible format that fits the particular item's needs.
A single-quantity small Fuji apple, picked today (October 3, 2026), with a PLU of 4129, and a magic-number lot code of b29sF, distributed by Stemilt Growers might present as such:
Apple Fuji Sm,B0261003,P4129,Lb29sF,MStemilt
A single 1.5 liter bottle of Crystal Geyser spring water with a UPC of 07514000500, a best-by date of January 12 of 2028, and a lot code of kek67:
Water Spring 1.5l,D0280112,U07514000500,Lkek67,MCG
We can even add more real information and still have less data to encode than:
...but, I mean: A coded URL for a website that might be designed to avoid being forthcoming with information isn't necessarily any better for consumers, long-term, than the UPC we've had for over 50 years. It's still just a pointer that relates to someone else's database. It has no informational value on its own.
Absolutely - I 100% expect the links to lead to feel-good marketing fluff at best and end up being useless for consumers, but the stated goals are at least good.
It's just that, sadly, we can no longer have nice things.

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

Edit: I looked it up. An example URL:
<a href="https://example.com/01/09521207311511/21/1234ABDE1235" rel="nofollow">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).
