Dynamic elements as copy protection
Visual tickets are issued and secured as dynamic barcodes or as VDV barcode mobile+. Today, standard-compliant barcodes are signed by security certificates. In the course of further development, the VDV barcode now receives copy protection through a dynamic security element. This is, for example, a time stamp that is renewed at intervals of a few seconds. If the ticket is then copied and sent, the dynamic element stops and no longer updates. When a copy is checked, it then immediately shows that it is an invalid ticket.
However, because of the dynamic element, Motics - unlike the existing barcode - can only be used on digital media that have an optical output, i.e., a display. A dynamic element on a paper ticket - that's not possible.
