Abstract
This invention relates to a process and device for avoiding fraud in a taxi equipped with a taximeter of extractable type, and consequently generally provided with a male/female coupling connector.It consists in providing, on each taxi receiving an extractable taximeter, a circuit memory which contains data for identifying the taximeter when it is connected to this taxi. This taximeter is prevented from functioning if such identification reveals that the taximeter is not the one which was calibrated for this taxi.
