BioMetricks is a multi-functional biometrics prank app that uses fingerprint scanning to determine results! You can either predetermine the result based on which area of the Start button you press, or set to random mode for random results.
Here are the built-in scanners, analyzers and detectors:
On top of these, you can also configure your own custom type, with its own name and results!
NOTE: This is a prank app that makes it appear like it is a fingerprint scanner. It does NOT actually scan fingerprints.
