Interesting, i've read about these Store Concepts for years as Test Projects from Rewe in Germany, but they never rolled them out widely. Probably sticking RFID on everything was too expensive. This camera based solution might be better suited for a wide rollout.

I remember having a discussion with a developer doing these RFID based solutions. He said one tag was back in those days about 10-15 cents each, which is way too much for supermarkets.

Talking about Rewe and German supermarkets, it's unbelievable how horrible the whole experience of doing grocery shopping is here in Germany. You almost always need to queue a lot, there is no space to pack your groceries and the cashier don't give you any time to pack until pushing the next customer's groceries to the small space.

They try to be efficient here, but the reality is quite chaotic.

If you're talking about discount supermarkets (Aldi, Lidl, etc), then note you're not supposed to pack your groceries at the cashier, but rather put them back into your shopping cart and pack up by the packing tables behind the cashiers. This way, checkout proceeds much faster compared to almost all other countries.
