A school bus app aims to help monitor students’ exposure to others. App developer CalAmp’s Bus Guardian uses the same technology from its Here Comes the Bus app with an added layer of contact tracing. With Bus Guardian, parents can opt-in and invite their student to check on and off the bus. It uses telematics to convert a school bus into a contact tracing solution. Schools can deliver instant and actionable reports of ridership based on contact tracing — important if a student or driver becomes ill.
