A digital lock is a type of locking mechanism that uses electronic components instead of traditional keys. It typically requires a code, keycard, or biometric input, such as a fingerprint, to unlock. Digital locks are commonly used in homes, offices, and secure facilities, providing enhanced security and convenience. These locks can be programmed to allow multiple users and can often be controlled remotely via a smartphone app. Some models even offer features like temporary access codes for guests. Overall, digital locks represent a modern solution for securing doors and other entry points, making them increasingly popular in today's technology-driven world.
