Thus, this innovative technology has prevailed in particular in public passenger transport, buses and trains as well as in air traffic, stadium and museum funds and parking ticket machines nationwide. However, there are still numerous problems in the very important field of application of parking tickets, which up to the present day could not be solved convincingly in their entirety.
