After placing an order in your restaurant, every client receives a unique QR code which can be used by you in order to quickly verify the order.
It may be especially useful when your client uses pickup delivery or delivery to the table.
You can scan this QR code directly from your app. In order to do that, you should click the scanner icon at the bottom right corner of the orders list.
After doing that, you get access to detailed information about an order and can check, for example, whether the order was paid or not.
