Connect phones by QR code

Pair a phone

1. In the web admin create a listener (or pick an existing one) and press the button to connect a device.
2. In the Berth app tap “Scan QR code” and point the camera at the screen — or tap “Enter code” and type the server address and the code.
3. The admin page shows when the phone is connected.

The code is 8 characters without look-alike letters (no 0, O, 1, I or L), works once and expires after two minutes. If it expires, show a new one.

Home and internet addresses

In Settings the admin can enter a home network address (e.g. http://192.168.0.4:8080) and an internet address (e.g. https://books.example.com). The QR code carries both, and the app switches between them by itself. For the internet address you need HTTPS — see installation.

What each listener sees

• The whole library or only picked books, sections, groups or languages.
• Age ratings 0+, 6+, 12+, 16+ and 18+: enter a child's date of birth and they see only books for their age. The limit grows with the child.
• Books without a rating can be shown or hidden.

Revoking a device

On the Devices page the admin can revoke any phone. The app on it signs out and deletes its downloads and library; links it got through the server stop working at once.

Login and password, if needed

For a phone that cannot scan a QR code, the admin can give a listener an optional login and password.
