Biometrics refers to the use of unique physical or behavioral traits such as fingerprints, facial features, voice patterns, or even iris scans to identify and authenticate individuals. These traits are nearly impossible to replicate, making biometrics a highly secure method for identity verification. But it’s not just about security. Biometrics are also enhancing convenience. No more remembering passwords or carrying ID cards your body becomes the key. In healthcare, biometrics are improving patient identification and reducing medical errors.
