When you open the fairpark 3 mobile application for the first time, you will be asked to access the camera on your phone. This access will be necessary for the mobile application to scan the QR Code displayed on your fairpark web interface (on computer or tablet) to authenticate you.
When you enter your entity code, the application opens your phone's camera. The QR Code can be found on your profile on the fairpark web application:
Do not share the QR code with others as this will give them access to your personal fairpark account !
