And what does a chip or a magnetic stripe do for you without a pin number?

My point is that the increased security is due to making people enter a four digit number. And to the best of my knowledge, ALL of the chips are RFIDS. They are claimed to be reduced sensitivity RFIDs so that supposedly they can't be read from a distance. But if they weren't "RADIO FREQUENCY identification devices", there would have to be contacts on the outside of your card.

That's exactly it. Mine is not RFID, it is a chip, with metal contacts on the face of the card.
