We upgraded the existing smart student locker system with 800 full-core lockers (wear-, scratch- and moisture-resistant) for students and university teachers. All locker doors are fitted with a unique hinge made of stainless steel, allowing the doors to open 180 degrees, the best option for students with hands full of books. Students can easily choose, reserve and pay for a locker rental online. Metra lockers system is seamlessly integrated with the central locker management software and the online locker rental payment service. There are over 2.500 smart lockers at different college buildings.
