Honestly it scans, beep, next
It has a screen and you can click a product to remove it (you need to rescan it)
Other than a time where I could not rescan a product to delete it, it always worked
Also an important note: you can actual see your total on the PDA, and you can manually check prices one by one
You don’t have idea how many times they put a price and then you scan it and it’s different
(Once I brought home 4x 200g hamburgers for 4 cent )
In North Italy almost all groceries stores offer
Self checkout: where you do your groceries and at the end you scan the item one by one
Advanced self checkout (you are registered to the store): you get a PDA and you scan and bag all the groceries while you roam the store. Then you scan a qr, you get the total, pay and go. No Id checks for alcol or anything (sometimes you get a random partial re-reading where you get an sales person coming and scanning 3 items at random from your bag to check if you scanned them, or a total re-read)
Normal slow cashier point
Advanced self checkout is something I would never give back. Even if I buy a lot of things, the quick payment process is so quick that nothing compares.
I can enter and leave a store in under 10 minutes buying a lot of stuff (note that I go there walking multiple time per week)
Not bad not bad man
