While I agree with you totally, you would be surprised the extent to which RFID has permeated almost every market. It's often not consumer facing, or simply invisible (there's a very good chance your shoes have a chip embedded in their sole...) but there are wide scale, functional examples in retail of exactly what you describe today. Decathlon, for example, a very large EU sporting goods store has this technology: RFID tags are baked into every product. You fetch your products, throw them all into a basket at checkout, and it instantly "scans" them all.
