Method for transferring of data within tachograph system used in motor vehicle, involves transferring data set stored in tachograph from tachograph to mobile data device as graphical code through cable-free optical data connection

摘要

The method involves transferring a data set stored in a tachograph (4) from the tachograph to a mobile data device as a graphical code through a cable-free optical data connection (8), where the graphical code comprises the data information of the data set. The mobile data device is designed as a mobile data processing device (6). The graphical code is initially set by the tachograph and then the set graphical code is detected by the mobile data processing device and is read in the mobile processing device.
