Disney have now placed RFID at the entrances at each of the four Walt Disney World theme parks.
Eventually the old turnstiles will be removed and replaced by RFID Readers. Guests will need to look for the new RFID logo of a Mickey head with a circle around it and simply touch their park ticket to the reader and place their finger on the biometric scanner. A green light will show that your ticket is valid, allowing you to enter the park. There will be Cast Members available to help if Guests have any problems.
At the moment the new entrances are accessible only by guests with RFID-enabled tickets, but eventually all tickets including annual passes will work with the system.
