In a shop in Italy if you are a member you can take at the entrance a scanner with you and then just pay in the automatic checkouts. Periodically (there is a statistical model behind I guess) you can be asked to be checked if the stuff you scanned are the same you have. So if you do mistakes, you will be checked more often. It seems to work pretty well, even with the old ladies.
