Biometric verification is a security process that uses unique physical characteristics to confirm a person's identity. Common traits used in this method include fingerprints, facial recognition, and iris patterns. This technology is often employed in devices like smartphones and security systems to ensure that only authorized users can access certain information or areas. The main advantage of biometric verification is its accuracy and convenience. Unlike passwords or PINs, which can be forgotten or stolen, biometric traits are inherently unique to each individual. This makes it a reliable way to enhance security in various applications, from banking to personal devices.
