A program of superlatives awaited the guests at the airfield in Interlaken: from the Chilbi and concerts to food stands and the eMobility Experience, where electric cars could be test-driven. The guests also had the chance to get a detailed insight into the company's range of services at various stands with Car Explainer, exchange ideas and enjoy the time together. We were responsible for the invitation and guest management, ticketing and virtual activities on both days of the event. We used the event web app we developed and expanded some features for the AMAG event platform. Before, during and after the event, all communication was provided both physically and digitally in the three national languages German, French and Italian. Ticketing was also expanded: managing your own profile and the associated family members, Print@Home and eTickets were available. Guests could also easily book test drives for the eMobility Experience via the platform. Fun and games were provided by the digital activation of a crossword puzzle and the scavenger hunt. Young and old alike searched for the hidden QR codes on the huge site. The virtual 3D map with information and clues to the secret locations served as support. Once found and scanned, the points were credited to the personal profile. The top scorers were able to win cool prizes after the event.
