There is an older article that talked about calling the RFID chips a
"super barcode" so people would be more receptive to the idea of
having the chips in everything.
One idea is to eliminate the checkers. You have an RFID tag on a card
issued by either the merchant or the credit card company. You just pile
your shopping cart and head for the door. Your cart is scanned and your
card dinged as you walk out the door. Mobil does that now with SpeedPass.
