You can use as many devices as you need. Students may scan their QR card at any device and the data will sync to the database, when the Sync Now button is pressed.
However, if you want students to hear accurate lap counts as they scan on the course, they need to scan to the same device for the entire scan session.
Please remember, it is a good idea to press the Sync Now button before starting a scan session AND after completing a scan session.
Note: If you have multiple teachers or volunteers that only need to log into the app to scan QR cards, you can create one Shared User account that everyone can use. Please click on the link that follows for directions on using and creating a Shared User account.
