biometric security systems

Biometric security systems use unique physical characteristics of individuals, such as fingerprints, facial recognition, or iris patterns, to verify identity. Unlike traditional passwords or keys, biometrics rely on traits that are inherently linked to a person, making unauthorized access more difficult. These systems are commonly used in devices like smartphones and secure facilities, providing an extra layer of protection by ensuring that only authorized users gain access. The technology works by capturing the biometric data and comparing it to stored information to confirm identity.
