Nobody has to wave across the hall. A guest taps a button and the staff phone shows which table needs help.
Once switched on, every table QR shows Call waiter and Ask for bill on the menu. A tap sends an alert to the staff screen and the Android app with the table's name, and the guest sees that the request was sent.
Requests only come from table QR codes, so the plain menu link you share online cannot ring your staff.
Starter and above.
No, the dashboard works in a browser, and the Android app adds alerts when the screen is locked.
Calls only work from a table QR, so they are tied to a table you set up.
