Qflow will run as expected with or without an internet connection. The only difference will be that your check-in data will be held in a queue on the check-in app until such time as your device reconnects to the internet.
Once reconnected all queued check-in data will be automatically pushed to your web dashboard and any other smart device connected and logged into your event on the Qflow check-in app.
You will see the check-in numbers in the bottom right hand side of the app build up when your device is off line.
PLEASE NOTE: You need to be connected to the internet to perform your initial event data download. Once all your event data is stored on your device an internet connection is not required to continue checking in and guests.
