Patent

CA 2532787

This publication discloses a method for identifying items, such as sheets of paper, or packages, a resistance mark arrangement, and reading apparatus. According to the method a mark made of electrically conductive material on the item is read contactlessly, in order to identify the item (7), or determine its properties. According to the invention, the precise absolute or relative resistance value of at least one electrically conductive mark (6) is determined and the measured resistance value is converted, for example, with the aid of a coding table or calculation formula, into information depicting the identity or properties of the item.

L'invention concerne un procédé pour identifier des articles, tels que des feuilles de papier ou des paquets, un ensemble marque résistante, et un appareil de lecture. Selon l'invention, une marque constituée d'un matériau électroconducteur et formée sur un article est lue sans contact, pour identifier l'article (7) ou déterminer ses propriétés. La valeur de résistance précise absolue ou relative d'au moins une marque électroconductrice (6) est déterminée, et la valeur de résistance mesurée est convertie, par exemple, au moyen d'un tableau de codage ou d'une formule de calcul, en informations sur l'identité ou les propriétés de l'article.
