Filed: 1980-11-27
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.
