Case study
Patrols for a security company
A security company in St. Martin needed to prove to its clients that every patrol had been carried out. We built two tools: a mobile app for agents, who scan a QR code at each checkpoint and report incidents with a photo and GPS position, even offline; and a dashboard for managers, who follow patrols live and send each client a PDF report.
