<P>PROBLEM TO BE SOLVED: To provide a glass plate which enables the ID of an automobile to be identified without hindering passengers' visibility or being easily removed. <P>SOLUTION: An identification code 11, which can be read with light of a wavelength outside the visible range, is applied onto a glass plate 10. The identification code is preferably a code patterned by an infrared reflecting film, an infrared absorbing film, an ultraviolet reflecting film, or an ultraviolet absorbing film and is preferably printed in the form of a bar code, a two-dimensional code, letters, English letters or symbols. The glass plate is preferably used as a windowpane for vehicles. The identification code, which can be read with light of a wavelength outside the visible range, is applied to a windowpane of a vehicle; the image of the windowpane by light is taken to extract the code from the image; and the ID of the automobile is identified based on the code. <P>COPYRIGHT: (C)2004,JPO |
