In an effort to combat fraud, children between the ages of 3 and 9 should now be prepared to have their fingers scanned when they enter the Walt Disney World theme parks.
The Orlando Sentinel reports that the new requirement is in place to help block the use of stolen and shared tickets. Older children and adult visitors have already been having their fingers scanned for years.
Previously, younger children's tickets were more easily transferable because they had no finger images attached to them.
Disney introduced scanners more than a decade ago that used "finger geometry" - pictures of several points on people's fingers.
Parents who feel uncomfortable with having their children get their fingers scanned can use their own instead.
