Contrary to popular urban legends, Disney does not share fingerprint data with the FBI or any other government agency. The "finger scan" required at park entrances is actually a biometric identifier used strictly for ticket fraud prevention. The system does not store an actual image of your fingerprint; instead, it scans several points on your finger and converts those measurements into a unique numerical code linked to your ticket. This ensures that multi-day tickets and Annual Passes are used by the same person throughout their validity. Disney explicitly states that these codes are stored in a private database and are typically purged 30 days after the ticket expires or is fully used. If you are uncomfortable with the scan, you can opt out by visiting Guest Relations and showing a valid photo ID for entry instead, though this may slow down your entry process.
