Every single instore item is tagged with an RFI chip, as small as a grain of sand. As you wheel your food trolley to the check out counter. Items are read, and tabulated into a receiver just ten feet away. The instant total and printout is handed to you as you pass go.
No more queuing. No stress. Utopia (for those that have?)
