Stop&Shop here in NJ has this and it's mostly convenient and faster than regular self-checkout. They occasionally stop you on checkout in order to scan some items to confirm you didn't "misplace" something. Unfortunately, this doesn't ease lines, as self-checkout lines are still long and you have to wait for your turn in these lines in order to pay. The only problem are missing shopping bags and scanners which are slow, still running some flavor of embedded windows, I believe made by motorola.
