The present invention relates to a memory-card reader comprising a board (10) for introducing a memory card (12) and a detector fitted with means for measuring the capacitive coupling between an electrode (22) and a reference potential. According to the invention, the introduction board is conductive and coupled to the reference potential, and the detector comprises means for comparing with a predetermined threshold the difference between the measured value of the capacitive coupling and a comparison value (C3) corresponding to the coupling between the electrode and the reference potential in the absence of bogus conductors. <IMAGE> |
