Cashiers and station managers, the day before

1. Install the QRnow Android app (the organizer gives it to you).
2. With internet, open it, log in with your account or your personal link and follow the steps to set up the phone.
3. Let everything download (the catalog, the vouchers and your permission) until it says it's ready.
4. Test: put the phone in airplane mode and scan a test voucher. It should turn green.
5. Set up every phone for the event, spares included. At the end, with internet, tap “Update” on each one: that way they all recognize each other offline.
6. Charge the battery and turn up the brightness. At the end of the day, go online to upload what you did.

The web page doesn't work offline: with no signal you need the Android app. An iPhone uses the web page with internet.
