PROBLEM TO BE SOLVED: To provide a rewrite card capable of reducing a magnetic recording function of a card reader/writer, and capable of reducing parts, manufacturing cost and size of a card reader.SOLUTION: A magnetic PET cloudy type rewrite card is provided by using a core sheet 3 that includes a transparent PET provided by laminating aluminum vapor deposition layer 3a, as a card base material, on which a rewrite layer 2 and a protective layer 2a are laminated, and under which a magnetic layer 4 and a silver layer 5 are laminated. A coloring layer 2 is provided by applying a heat sensitive special coating material that repeats transparency and cloudiness by heating and typified by an organic low molecular substance. The card is partitioned into a first bar code printing area A1, an information display printing area A2, and a second bar code printing area A3 in order from the head side toward card insertion direction. In the printing area A1, one dimension bar code is printed and in the printing area A2, the Kanji and the Arabic numeral are printed. Then the card ID information corresponding to the first bar code data B1 is recorded in the magnetic layer 4 of the rear surface of the card 1 beforehand. |
