Smart lockers are secure storage units that use technology to manage access and deliveries. They are often found in places like offices, schools, and apartment complexes, allowing users to send and receive packages without needing to be present. Each locker is equipped with a digital keypad or app interface, enabling users to unlock their designated locker with a unique code or mobile notification. These lockers enhance convenience and security by reducing the risk of package theft and ensuring that deliveries are safely stored until the recipient can retrieve them. Smart lockers can also streamline operations for businesses, making it easier to handle incoming and outgoing items efficiently.
