This past December when I was driving back one night to the Boardwalk the Cast Member working at the guard shack took out an RFID scanner, scanned my KTTW card and said my name along with a welcome home. If you still don't know what I'm referring to I believe this is the same device that the restaurant servers use when you want to charge something to your room. So I'm wondering is this something all the other WDW Resorts are now using?
