There is a Kroger by my house that gives you the option of scanning and bagging as you shop.
How does this technology know that every item in the cart has been scanned? Or that the correct item has been canned (scan the barcode of a cheap product but then put an expensive product in your bag)? This seems like it would be very prone to shoplifting or open to legitimate mistakes (your little kid throws an item in the bag that you don't notice and it never gets scanned).
