The Expert Service of “Novatronic”, in cooperation with a team of engineers of “Appex Solutions”, managed to integrate our devices into” Bus Plus” ticketing system. In this manner, by integrating two independent systems into a single one, a maximum utilization of the system is reached, and thus, a significant costs reduction is achieved. For the time being, this has been performed at 200 vehicles and a plan for the near future is to integrate vehicles of all Belgrade carriers, as well.
