Measuring and visualizing visitor satisfaction at events and in stores.

Visitors are given the opportunity to give their opinion directly on site. This is possible either by interacting with one of our terminals, a tablet or their own smartphone - the visitor can simply scan a QR code or enter a web link. The focus is always on simple and intuitive use.
