<p>PURPOSE:To realize safe and certain exact calculation even when magnetic recording is erased by performing printing under the other pressure of magnetic recording. CONSTITUTION:A magnetic recording strip 12 recording data is provided to the rear of a card 10 and self-contained paper 16 constituted of a coupler layer 15 and a colorant layer 14 is provided to the surface of a card base 13. The colorant layer 14 of the self-contained paper 16 is formed by applying microcapsules including a colorant and the coupler constituting the coupler layer 15 forms a color by chemical reaction generated by the mixing with the colorant. Therefore, when printing or typing is performed on the card 10 by a printer, the microcapsules of the colorant are broken by the printing pressure thereof and the colorant is immediately absorbed in the coupler and forms a color by chemical reaction to display printing data on the card. Therefore, even when a tape is bonded to the card to perform printing, printing is certainly performed.</p> |
