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 are designed to enhance security by ensuring that only authorized users can enter a specific area. Unlike traditional locks that require keys or codes, biometric locks provide a more convenient and secure method of access. They are often used in homes, offices, and secure facilities, making them a popular choice for protecting valuable assets. With advancements in technology, biometric locks are becoming increasingly reliable and user-friendly.
