<p>A data card having a storage region for storing capacitive data, and a reader thereof. A card (5) has a magnetic storage region (10) for storing magnetic data and a capacitive storage region (12). The capacitive storage region (12) is provided with a plurality of electrodes connected through fuses, and bit data are stored depending upon whether the fuses are blown or not. The data are read by detecting current flowing in circuits that are connected to the external electrodes by capacitive coupling.</p> |
