Make amazing pranks to your friends, be the partys master!!
Fill up the applications data with real data of the person who youre going to prank. Start the scanner so they can put the fingerprint against it.
The application will make them believe that the fingerprint has been sent to some database from some super-secret organization, showing on-screen personal data no one should know!!
IMPORTANT
Its just a joke, the application doesnt scan anything neither send any data to anywhere.
