<p>PURPOSE:To give a value judging data other than the size and the weight inside a coin, so as to prevent to forge by an outsider, as well as to make the judgement of the coin easier and securer, by including a built-in IC in a disk-form substance in appearance. CONSTITUTION:In a disk-form substance in appearance, an IC 12 is built in. Therefore, since a coin is made into an IC furnishing a cell to generate a power by radiating the light to a disk-form substance in appearance and an electric circuit to output a predefined data to the outside through a luminous element, not only the judgement by the scope of the size and the weight used in the conventional coin judgement method can be carried out but also the confirmation of the coincidence with the coin by the communication data can be carried out additionally. Consequently, a forged coin of the same size and weight can be detected easily, and an unjust use of the coin can be prevented.</p> |
