Our fortknox® had scared us to the end of 2017 and took us quite a sweat, he did not want to perform the liveness detection sporadically.

At first we only suspected a software problem, but unfortunately it turned out that the hardware caused the error – CPU too small.
Thus, we are now working on hardware revision 3.
Not nice, because it throws us back in time and we probably will not be on “light + building”, but now we have the chance to integrate a few things that were previously solved externally.
