biometric applications

Biometric applications use unique physical or behavioral traits—such as fingerprints, facial features, voice, or iris patterns—to identify or verify individuals. These methods enhance security by allowing access to devices, buildings, or accounts only when recognizing the authentic person. They are widely used in smartphones for unlocking, at airports for faster passport control, in banking for secure transactions, and in workplaces for attendance tracking. Biometrics offer a quick, convenient, and reliable way to ensure that only authorized individuals gain access, reducing fraud and improving safety across various sectors.
