During 2012 and 2013, Walt Disney World on property resorts will be switching to a wireless door lock system. The new locks will work with Radio Frequency Identification (RFID) technology. Guests' Key to the World Cards will allow access to the rooms like before, but instead of inserting the cards into the locks, guests will just need to tap the lock for the door to open. The cards look the same, but the placement of the clouds and castle will be different. The new technology is already in place at the Art of Animation Resort, Contemporary Resort, BoardWalk Resort and Yacht & Beach Club Resorts. Guests will be seeing much more RFID technology in the future, as Disney will be implementing this in their upcoming "NextGen" program.
