According to WDW News Today, Disney’s Animal Kingdom is testing added ticket security and it is expected to go into full roll out next week. Currently, guests scan their theme park tickets or Disney MagicBands, then give a thumb print using the bio-metric scanners at each turnstile. With the new security, if a guest’s bio-metric scan should fail multiple times, they will be escorted to guest relations where they will have to answer a series of simple questions. (IE What is the name on the ticket?, How many days is this ticket good for?) Once the guest has answered the questions, and it’s been verified that the ticket belongs to the guest, guest relations will then take a picture of the guest. This will allow Cast Members to verify the guest’s ticket should the bio-metric system fail again.
There is already a similar security measure in place at Disneyland Resort. Each guest that enters Disneyland Park or Disney’s California Adventure Park gets their picture taken at the turnstiles on the first day of use, with each entry Cast Members scan the guest’s ticket and verifies that the picture in the system matches the guest.
