> The original pitch for the RFIDs was that they'd just be able to scan your whole cart. I'm sure the limiting factor at the moment is the incremental cost to the product. If an RFID tag costs 25¢ would you be willing to spend $1 instead of 50¢ for a can of corn, just for the privilege of not interacting with anyone? You might, but the average customer won't.

RFID is primarily used in application where the tag can be reused. I haven't seen many disposable RFID tags.
