Behind the Scenes

Several different games were tested, for example a card game. Ultimately, it was decided to implement a wheel of fortune because it is self explanatory.

Coupons can be printed via a mobile bluetooth label printer. The implementation of the printer was a special technical challenge.

For business reasons its necessary to track the generation of coupons. Generated coupons are saved in a database where they can be imported into the inventory control system. This has to work even when there is no connectivity at the current event. In that case, data has to be saved offline and synched as soon as an internet connection is available again.
