A few months ago my team was challenged to digitize the work of the General Services Department in our offices. To improve the process we created a Google App Maker web-app designed to be used on Chromebooks in tablet mode. To track usage and movements, Cloud SQL stores data in tables: packages, movements/history and anomalies declared by teams. In order to retrieve the hexadecimal code of the badge, it’s really easy. A card reader behaves like a keyboard !
