Truck Hacking

Truck drivers have a little device in their truck that logs driving and speed and time.

In the past truck drivers used a magnet to jam the signal so that they could drive longer that they were allowed to.
But nowadays the magnet trick doesn't work anymore.

Does anyone know a working method to tamper/jam the tachograph?

Compiling data from all tachographs can show a great deal about how often company policies are followed. They can also show work patterns and how well workers were able to meet goals.

give it an on/off switch =)

use cheat engine
