A "Biometric Clock-In App" is a dedicated mobile application designed specifically to facilitate the precise recording of employee work start and end times, as well as breaks, through biometric authentication. Its core function is to serve as an intuitive and secure digital time clock accessible directly from an employee's smartphone or tablet. The app streamlines the daily ritual of "punching in," making it faster, more accurate, and resistant to fraud by leveraging the unique biological characteristics of each individual.
