Drivers can work in teams (or solo) by sharing links to OpenSesame Library files with each other from their google drive, icloud, or dropbox. Your codes are kept safe, local and can be exported at any time! Quit fumbling with screenshots and old paper notes, and watch the gates open to faster deliveries today with OpenSesame!
