The entry method was previously reserved for adults.
Finger scanning has been a security measure at some Disney parks for over a decade. Now Disney World has rolled out an official finger-scanning entry method for all visitors to Walt Disney World over the age of three.
Previously, this entry method was only required for park-goers aged nine and up. The move is an effort to help reduce ticket fraud and ticket swapping.
If parents aren't comfortable with their children using the new system, they will be able to scan their own finger to account for the ticket instead.
The finger-scanning system is not meant to store data long-term: All of the prints are erased at the end of the day, according to a Disney spokesperson.
