Description Traditionally, chairs at event venues need to be manually equipped with seat numbers after each set-up; a procedure that requires a great deal of time and manpower. The innovative information system n° e allows quick grouped numbering of seating at the touch of a button.Thanks to an intuitively operated app, the e-paper colour displays can be individually controlled at any time from any location. But n° e is much more than a mere replacement of analogue seat numbers. With its numerous options for networking and customisation, the information system creates new possibilities for the interaction between organiser and guests, e.g. for a personal welcome message, for navigation, or for advertisements. Future plans such as the system’s connection with ticket agencies, the processing of payment transactions or the interactive involvement of guests at events are already envisioned.
