Pairing Devices

On the device (login screen) pick one of 3 modes:

• Cashier — sell, members
• Scanner — entry/exit
• Public Kiosk — public ticket status

Then tap Scan QR → point at the QR from the Host, or paste the token manually → confirm.

First visit? The app runs over HTTPS (https://<host-ip>:43118). Your phone will show an untrusted certificate warning — tap Advanced → Proceed (once per device). The cert is self-signed for your local network and is safe. On phones, open the HTTPS address from the QR; on the Host PC itself use http://127.0.0.1:43117.

Inventory devices aren't on the login picker — get an invitation from Owner → Devices (employee name + Staff role) and scan it.

Device lifecycle

Paired devices appear in Owner → Devices with employee name. The list updates live:

• Connect — device pairs/logs in → toast "A device connected" + appears in the list immediately.
• Disconnect — device app closes or loses network → toast "A device disconnected"; the list shows it as offline (no auto-removal).
• Logout — Cashier/Scanner/Kiosk taps Logout → device is removed from the list and must re-pair with a new QR to come back.
• Revoke / Delete — Owner-side actions kill the session; same as logout for the device.

Owner Dashboard is protected (cannot be removed).

After repair

If Host Overview shows Host IP changed banner, re-show QR and re-scan on each phone (once).
