Project Overview
About Lokr
LOKR is a Smart IoT-enabled Parcel Locker System designed to modernize last-mile delivery by enabling secure, automated parcel drop-off and pickup through connected locker stations.
The platform integrates IoT-enabled locker hardware, web applications, and administrative dashboards to create a complete parcel management ecosystem. It allows couriers to securely deposit packages in smart lockers while customers can retrieve them at their convenience using secure authentication methods.
By automating locker allocation, enabling real-time parcel tracking, and providing centralized monitoring, LOKR improves operational efficiency for delivery companies while offering customers a secure and flexible pickup experience.
