The invention relates to an information carrier comprising at least one information layer which optical properties depend on a potential difference applied between two electrodes (531,532). The information carrier is intended to be scanned by an optical scanning device comprising means for generating a signal comprising information about a selected information layer. The information carrier comprises means (51) for receiving this signal, means (521) for decoding this signal and means (522-524) for applying a potential difference between the electrodes corresponding to the selected information layer. |
