When customers scan the QR code with their smart phones, they are directed to the Customer Portal. In this portal, they fill the request, wish and complaint form or the company's questionnaires if they wish.
This form data is stored in your company's data collection center and instant notification is sent to the relevant persons. Thus, the relevant persons can contact customers instantly if they wish. In addition, you always have the data obtained.
You can see which customer has written to you from which location and from which branch. Customers can subscribe via social media and thus join your network.
