    • PROBLEM TO BE SOLVED: To provide a non-contact type IC card reader/writer with a simple circuit configuration, allowing enlargement of a communication distance while suppressing heat generation without supplying excessive power to an IC card. SOLUTION: This non-contact type IC card reader/writer has a load impedance detector 12 for detecting load impedance of a coil antenna 11 in the reader/writer 10, and has a drive circuit 13 increasing or reducing transmission output from the reader/writer 10 side on the basis of fluctuation of the load impedance to perform output control.

    • PROBLEM TO BE SOLVED: To prevent forgery by comparing and collating an authenticater within a host computer prepared by a ciphering function obtained by ciphering frequency information and card characteristic information with card characteristic perforated information as a key and an authenticater within the magnetic card read into in advance. SOLUTION: At the time of authenticating a card, the authenticater within the magnetic card 16 recorded on the magnetic card 1 is read by a magnetic head for reading and writing magnetic information. Next, characteristic perforated information obtained by reading a perforated part 12 by means of an optically reading head 7' and characteristic perforated information obtained by reading the perforated part 12 by means of a magnetically reading head 7 are compared and collated with each other within the host computer 3 to confirm the authenticity of characteristic perforated information. If being correct, an authenticater is prepared within the host computer 3 by setting frequency information read by the head 5, a lot number 11 read by a lot number reading system 6 and characteristic perforated information 12 read by the head 7' to be keys to compare and collate with the authenticater within the magnetic card 16 read in advance.

    • PURPOSE: To provide a method for manufacturing a plastic card which can be safely used in the field of a prepaid card. CONSTITUTION: In the step of laminating a sheet of a method for manufacturing a plastic card, an oversheet 5 made of a transparent rigid polyvinyl chloride previously attached with a magnetic stripe by a heat transfer is prepared to a core sheet 3 made of opaque white rigid polyvinyl chloride from its rear side, an oversheet 4 not attached with a magnetic stripe is provided to the sheet 3 from its front side, and laminated to obtain a card base. In the subsequent step of forming a recess, the front surfaces of the oversheets 4, 5 of the base are thermally press-bonded in the state held between mirror metal plates 1 and 2 provided with protrusions to obtain a plastic arc laminate having a predetermined thickness. In the step of punching the laminate, when it is punched in a predetermined size, the card in which a recess is formed as for perforating a punched hole for exhibiting the criterion of the number of using degree on the surface is obtained.
