Before a person can download files from a digital tachograph, they need to prove to it that they are someone who is entitled to access the data. This process is called authentication and is usually performed by inserting a company card into the tachograph. Authentication can also be achieved by a company card and a tachograph communicating with each other when they are not in the same place.This process is known as remote authentication.

DigidownHost is a cross platform (Linux/Windows) application which allows remote authentication to take place by handling communication between a company card and a DigidownT/RDL or DigidownBlue device connected to a digital tachograph.

DigidownHost is capable of handling communication for one or more companies each with one or more company cards. Remote authentication can then take place between a vehicle’s tachograph and any company card associated with that vehicle’s company.
