Tinder uses Apple’s technology, Touch ID.
People could only access Tinder through its new feature, TinderTouch.
All information on sex criminals is provided by the FBI.
The FBI has a huge fingerprint database, so Tinder can team up with the FBI to prevent criminals from joining Tinder.
Tinder checks new users based on the FBI’s fingerprint supply.
When creating a new Tinder account, the user must give their fingerprint, so users cannot hide their real identities or criminal records.
If the user’s fingerprint matches one of a sex offender, Tinder will not allow the user to join. As a result, Tinder users don’t need to worry about meeting potentially dangerous sex criminals.
