Tachographs: new opportunities to work with DDD files

Tachograph data on driving and rest periods are to be provided to regulatory bodies from time to time. Usually DDD files can be downloaded from a driver card through a digital tachograph. But it’s not always possible.

Wialon offers ample opportunities to work with DDD files and online data on driver activity including remote downloading of DDD files from a driver card. Now we move on and release a new handy app for reading the driver card data through a USB card reader.


To work with the app you need a PC with Java installed, a USB card reader and a driver card.

After you insert a driver card to a USB card reader and then connect it to a PC, go to the main menu click Card -> Save DDD File.


The app will ask for a path to save a DDD file. Choose it and click SAVE. You don’t need to name a file – it’ll be generated automatically in VDO format.




The application works with any driver card data type. Hope it will be helpful for you to work with tachograph data.

Have a nice day!
