Radio Frequency ID, or RFID, payment terminals recently started being tested at Disney's Contemporary Resort.
Under this new system, guests staying at a resort will be issued a "Key to the World" resort card. The card will let the guest "pay" for an item, say, at the gift shop with the purchase being added to the guest resort bill. In addition to being a new means to pay for items throughout a resort, the RFID cards will also be equipped to open a guest's room.
