Here’s a bit of a stretch for an online registration software company. How about letting your trade show exhibitors select their booth from an online floor plan.
In this example, http://bit.ly/1bIE84a a gardening trade show asks potential exhibitors to apply for a particular booth. The application is done to ensure that the exhibitor is suitable for the show. Once the application is approved, a cashier processes the booth order and the booth square on the floor plan turns from green to red.
The online floor plan allows exhibitors to see which companies are near and how large the show will be.
