<p>PROBLEM TO BE SOLVED: To recycle one sheet of an ID card for a plurality of temporary employees by rewritably displaying information regarding a card holder, and also, rewritably recording the information regarding the card holder. SOLUTION: As the material for center core sheets 3a and 3b, a vinyl chloride-vinyl acetate copolymer is formed into a sheet of a thickness of 0.3 mm. In the meantime, for oversheets 4a and 4b, an antibacterial agent 5 is mixed with the vinyl chloride-vinyl acetate copolymer, and a roll of a thickness of 0.1 mm is formed. Then, a magnetic recording section 6 of a magnetic stripe is transferred, and the roll is cut into the same size as the center core sheets 3a and 3b. Then, they are press-laminated. Then, they are punched into the size of a card. Next, a recess is formed at two locations of the card base material, and a magnetic display section 13 wherein the surface is covered with an IC module 9 and a protective layer 18, is embedded and bonded, and thus, this ID card is produced.</p> |
