Upon request, you will receive personal login credentials from Order-Control Support, which you can enter into the "Order-Control | Android Connect" app.
The app runs continuously in the background. When a call comes in, the phone number is automatically transmitted to the Order-Control server.
There, the phone number is assigned to your Order-Control POS ID. Subsequently, either the new customer form opens automatically in your POS system, or the corresponding existing customer is selected directly.
