An electronic lock is a modern locking system that uses electronic components instead of traditional keys. These locks can be opened using various methods, such as a keypad, a smartphone app, or even biometric features like fingerprints. This technology provides enhanced security and convenience, making it easier to manage access to homes or businesses. Many electronic locks are designed to integrate with smart home systems, allowing users to control them remotely. For example, a user can grant temporary access to a guest through their smartphone while keeping track of who enters and exits. This level of control and monitoring is a significant advantage over conventional locks.
