There is a European sports store called decathlon that uses RFID. Put a tennis racket, running shoes, football, horse bridle, socks, ski goggles, bike tyre etc (they sell everything you can think of) in your basket, go to the till, place the basket in a blue outline at the till and it reads everything in your basket immediately. No scanning! I was really impressed. I did some prototyping with RFID a few years back and reading multiple cards in unpredictable positions (e.g. overlapping, side-on) was quite challenging but looks like decathlon have worked it out.
