The tachograph and driver card are authenticated using the company card. Driver card and/or mass memory data is compiled and encrypted. The DLD® Short Range II transfers the encrypted data to a PC via the local wireless network (WiFi). Please note: A chip card reader is required to read the company card, for example the VDO Card Reader. For TIS- Web® customers, the data is transferred directly to the TIS-Web® server via a secure Internet connection (https), where it can be archived and evaluated.
