Our security checkpoint management system is an effective tool to manage daily operations and enables deep performance analyses within airport security checkpoints. It combines granular data gathered through our IR-UWB radars and in-depth knowledge on a complex process into a unique solution. We’re looking for someone to take our application to the next level and to new industries.
