The technology characterized by biometric access control includes systems that utilize unique biological traits, such as fingerprints, facial recognition, or iris scans, to authenticate users. These systems enhance security by offering a more reliable alternative to traditional passwords or PINs, which can be compromised. Biometric technologies ensure that access is granted only to authorized users, thereby reducing the risk of unauthorized entry. They are increasingly used in secure areas, mobile devices, and applications requiring high-security measures to safeguard sensitive information.
