    • The invention relates to a marking electromagnetically readable from a substrate, a method for producing such a marking, and a memory medium. The marking comprises first areas on a substrate at a distance to each, which comprise at least one electrically conductive material and the electrical conductivity of which is greater than a defined threshold value, and second areas arranged between the first areas, the electrical conductivity of which second areas is less than or equal to the said threshold value. According to the invention, at least two first areas differ substantially from each other in electrical conductivity. With the aid of the invention it is possible to create a marking, the amount of information contained in which is many times that contained in previous electrical markings.
    • 本发明涉及从基板电磁读取的标记,用于制造这种标记的方法和存储介质。 标记包括在每个距离上的衬底上的第一区域,其包括至少一个导电材料,并且其电导率大于限定的阈值,以及布置在第一区域之间的第二区域,其电导率 第二区域小于或等于所述阈值。 根据本发明,至少两个第一区域在导电性上基本上彼此不同。 借助于本发明,可以创建一个标记,其中包含的信息量是以前电子标记中包含的许多倍。
