According to the present invention, a card-type electronic medium can be reused by using rewritable (rewrite) display means as a display means for the card-type electronic media, and the global environment can be improved by eliminating a large amount of paper. Can be. If a leuco-type thermosensitive recording rewrite material is used as the rewrite display means, rewriting can be repeated several hundred times, and if a liquid crystal display device is used, rewriting can be performed hundreds of thousands of times, Since the content of the display screen can be changed, much information can be displayed.

Further, according to the present invention, since the display information is stored in the semiconductor recording means and transmitted to the electronic medium reading device by the wireless communication means, the display information is compared with the case where the display information is stored in the conventional two-dimensional code. Therefore, since there is no reading error due to dirt or bending seen in the two-dimensional code, high reliability is obtained, and high-speed communication of 100 to 200 KBPS is possible, so that business efficiency can be improved.

Further, in the case of the present invention, even if a two-dimensional code is used, since it is displayed on the surface of the card or on the liquid crystal, there is no dirt or bending, and no reading error.

Further, by coexisting with visual recognition data (rewrite display) by eyes, a smooth transition from the conventional system is possible, and even if the semiconductor recording means or the wireless communication means breaks down, the operation is not fatally damaged. It is an advanced electronic media system that meets the needs of the age of reuse and reuse.

Further, since the electronic media of the present invention can be used in a wide range of applications, they are industrially extremely useful.
