The invention relates to a screw fastener comprising a threaded shank having a force application means for torque transmission and a screw fastener point. A computer is configured so that a secure boot function is set as enabled by default. A second die having electrical circuitry implemented on a top surface is attached to the top surface of the first die. The report definition file defines how the report is to appear and where the data used in the report is stored. The keeping circuitry comprises third and fourth switches serially connected between the logic node and the first potential and being controllable separately from each other, the third switch being adapted to be closed in case a potential on the logic node assumes the first potential and to be opened in case the potential on the logic node assumes the second potential.
