I remember visiting a fully automated store already in the 90's in Tromsø, Norway. It was like an extended vendoring machine. It was quite fun watching the robot hand go up and down based on your order. I believe such stores were already common in Japan at the time. The shop didn't make it, though, and was discontinued after a year or two. Today automated checkouts are popping up in more and more shops in Norway, though they're not present in all stores yet. You simply do your shopping as normal, but instead of having a shop clerk beep them for you, you have to do it yourself. It's pretty straightforward, and no app is needed. Sometimes there will be a guard overseeing the terminals, but mostly you're left to your own devices. Otherwise there's usually a normal teller on hand for questions or for products that don't scan. Or if you simply want to pay with legal tender, which Norwegian shops are still obliged to accept per law.
