When I started reading the description, I thought: "someone finally delivered on that RFID pitch of just walking out of the store". Was surprised that it's actually computer vision.
Same. I remember predictions of RFID-based shopping becoming the norm 10 years ago, but it never happened. Does anyone know why the tech didn't pan out that way?
RFID tags are still to expensive in the supermarket context. The margins are usually razor thin (at least in Germany) and the products are quite cheap. Even when buying RFID tags in bulk they are too expensive.
