Abstract
An electronic device, placed in an impregnable envelope and electrically connected between an electronic sensor and a taximeter or chronotachograph, tests at least one of the internal characteristics of the active dipole present between two output wires of the sensor or electrical characteristics of a signal present at its terminals. The test values are then compared with one or several reference values. An electronic anti-fraud action is triggered in the event of non-conformity between the test values and the reference values. One anti-fraud action includes preventing the functioning of the taximeter or chronotachograph.
