Biometric locks are security devices that use unique physical characteristics of individuals to grant access. Common biometric features include fingerprints, facial recognition, and iris patterns. These locks provide a higher level of security compared to traditional keys or passwords, as they rely on traits that are difficult to replicate. These locks are often used in various settings, including homes, offices, and secure facilities. They can be integrated with smart technology, allowing users to control access remotely. Biometric locks are becoming increasingly popular due to their convenience and enhanced security measures, making them a reliable choice for protecting valuable assets.
