*Note: This app is meant for entertainment purposes only. The thumb print scan is only a simulation, and it does not actually have the ability to tell how lucky you are! This is only a game! Fingerprint Luck Scanner is a novelty prank thumb print scanner app that pretends to determine how lucky you are based on a mock fingerprint scan. Simply place your thumb on the scanner and the app will give you a random horoscope! Great gag for parties or for impressing the ladies at the club! Luck Scann
