> It feels like almost all the issues with self-checkout technology come from the attempts to minimise shoplifting, which don't even seem that effective at doing that. In theory, a system that let you scan products the same way checkout staff do without any weight checks or bagging area rules or other interruptions would be incredibly efficient. Especially if you could do things like scan the same product multiple times if you were buying multiple copies of it.

Our local supermarket has this. A phone app you scan things as you go, and when leaving you scan a QR code, swipe to pay, then you get a code to open the gate out and you leave. It's incredibly smooth. Also, this means you can just put your bags in your cart and bag while you shop, so you just completely skip checkout, it's a breeze.

I don't understand your point about scanning multiple times though. If I'm buying 5 of something I scan one of them, and just increase the count to five.

Many self checkout systems check for the weight of scanned items, so if you scan an item you have to put it down (“please place item in the bagging area”) in order to continue.
