It's possible with RFID. Just not cheap enough yet.

  They put RFID in one way underground ticket now. The time it is cheap enough to include everywhere is coming fast. However, I'm not quite sure that will be enough for shops to automate. The problem for shop is that an automated system most likely cause of failure is to miss items. That added to the likely need to remove some security features to simplify automation and the already existing shoplifting problem means shop owner will be more interested in more clever (read more obnoxious) self checkout system than automated ones.
