biometric identification systems

Biometric identification systems use unique physical or behavioral traits—such as fingerprints, facial features, iris patterns, or voice—to verify or identify individuals. These systems capture these traits with specialized sensors, create digital templates, and compare them against existing data to confirm identity. They are widely used for security, access control, and authentication because biometric traits are difficult to duplicate or forge, providing a reliable way to distinguish individuals quickly and accurately without needing passwords or ID cards.
