That was always the dream of the big retailers: push a cart through a gateway and your order is tallied instantly.
However, you need RFID tags on each and every item in the store, including produce and things you scooped into bags yourself. And, at Walmart scale, adding $0.02 per item in packaging is probably a margin killer.
Uniqlo is able to do this because they produce and tag the items by themselves. I agree it's cool, but it's a very narrow case.
