My local shop around the corner doesn't even require scanning a card or anything like that. Just get the handscanner at the entrance by pressing the button on the screen. Scan your shit and put it in the bag, go to the self checkout, put the scanner in the machine, touch your phone to pay and it's done. I love it, I can be in and out in about 1 minute if I only need a couple of things. They've put in about 10 self checkout machines in the place of 3 old fashioned checkouts. Usually there is only one oldskool checkout open with a large line of old people.

Only irritating thing is people with like 100 items scanning all their shit at the checkout (if you don't want to use the handscanner), it takes forever. I don't get why people do that, but luckily there are enough self checkouts there is always one free.
