Digital locks are security devices that use electronic mechanisms instead of traditional keys to secure doors and other entry points. They often require a code, key fob, or biometric data, such as a fingerprint, to unlock. This technology provides convenience and can enhance security by allowing users to change access codes easily and track entry logs. These locks can be found in various settings, including homes, offices, and hotels. Many digital locks are compatible with smart home systems, allowing users to control access remotely through their smartphones. Popular brands include August, Yale, and Schlage, each offering different features and levels of security.
