Abstract

PURPOSE:To make it difficult to alter or falsify a card, by making it impossible to discriminate the contents of the data on the card from the card external appearance by providing plural data holes plus a false data hole to fit the optical elements having different selection properties of wavelength to those data holes respectively. CONSTITUTION:A false data hole having the same shape as a data hole is provided in addition to plural data holes drilled at the desired positions, and optical elements having different selection properties of wavelength are fitted to these holes 11 respectively. For instance, an optical filter 12 is fitted at the middle part among the holes 11 drilled at the positions for data on an optical card 10. Then an infrared ray absorbing filter 12A which transmits the visible light but absorbs the infrared ray is used along with an infrared ray transmitting filter 12B which transmits both the visible light and infrared ray. Thus the filter 12A is fitted into the hole 11 at the position where no application is required for the input data. while the filter 12B is fitted only into the hole 11 at the position that is used as an input data.
