My supermarket implemented these barcode scanner you can carry in the store so that you can scan and put your stuff in your grocery bags in your cart as you go, as well as some scales so that you can also scan those items paid by weight, which you can then scan at the self-checkout terminal. They also spot-check every 4th scanners and scan for random items in the cart to make sure you actually added them to your list as a theft-deterrent.
It’s way faster and less finicky than dealing with the scale that checks if you added the item you just scanned (and complains often that something’s wrong).
I hope this kind of system will stay, it’s really nice going to a self-checkout terminal and pay with your bags already filled.
when I worked at a grocery store for a bit (until a year go), we had that kind of system alongside the regular and self checkouts. It was interesting to see as I had never heard of it before, but it was very fast when it worked. That being said, almost nobody actually used it, and whenever the random checks happened it was almost always when someone had bought more items than usual (not sure if that actually triggers anything or if it was just coincidence) and the system for looking through everything was frustratingly slow for both me and the customers. I feel like the scanners are a great idea, but the theft-deterrent system for it could use a rethink, though Im not sure what exactly could best replace it
