biometric system

A biometric system is a technology that identifies individuals based on unique physical or behavioral traits, such as fingerprints, facial recognition, iris patterns, or voice. These systems scan and analyze these traits to create a digital template that can be compared against stored data, ensuring secure access to resources like phones, computers, or secure facilities. Because biometric traits are difficult to replicate, they enhance security and reduce the reliance on passwords or PINs. Biometric systems are increasingly used in various areas, including smartphones, airports, and borders, to improve safety and convenience.
