A SIM reader/writercan be removably loaded with a SIM. The SIM reader/writerhas a case, a controlling IC chipplaced in the case, a USB/ISO7816 conversion IC chip, and an coil antennafor noncontact communication placed in the case. The caseis provided with a liquid crystal display, a fingerprint sensorand a short-distance communication means

A sheet-framed IC carrier has a sheet frame having an aperature, and a backing film with a pressure-sensitive adhesive layer on one surface thereof which is adhered to the back surface of the sheet frame. An IC carrier having an IC module is secured in the aperature of the sheet frame with the adhesive layer on the backing film. When the IC carrier is removed from the sheet-framed IC carrier, no excessive load is exerted on the IC module and no projection remains on the peripheral edge of the carrier base.

The present invention relates to an optical recording medium which has excellent scratch resistance and resistance to cracking derived from warpage and bending. It comprises a card substrate; and, laminated on the card substrate, an optical recording member comprising a laminate of a transparent protective layer and an optical recording material layer, wherein a specific surface hard layer is provided on the transparent protective layer.

A magnetic recording structure comprises (1) a substrate having an outer surface, and (2) a laminar magnetic recording piece disposed adjacent to at least one part of the outer surface of the substrate, the recording piece comprising a magnetic layer, a color layer and a non-magnetic metal deposition layer interposed between the magnetic layer and the color layer, the magnetic layer being closer to the substrate than the color layer. The non-magnetic metal deposition layer disposed on the magnetic layer has high hiding power and, even in the form of an extremely thin layer, can effectively hide the color of the magnetic material. Accordingly, this magnetic recording structure can be produced with a surface of a beautiful color without impairing its magnetic characteristics.
