Abstract
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.
