Here in France the larger Carrefour stores have another system in addition to the usual self-checkouts. You can grab a scanner at the entrance and scan each item as you take it from the shelf. At the checkout they check a few random items and you pay. It's fast when you buy a lot of items. You do have to get used to scanning stuff yourself, which takes some practice.
