RFID self checkout was the best self checkout i witnessed. Just put all your items in this box at the self checkout and automagically all your items get listed on the screen, you pay and thats it. The User Experience is so good, but to have this every product needs an rfid tag and i don't think this will be achievable for every store. For example grocery shopping, imagine every little chocolate bar and chewing gum would need an rfid tag. Maybe it will get more and more to clothing stores, as most of them already have an rfid tag for theft detection.
