  • Label having an electronic circuit
    Patent number: 6911911
    Abstract: A label comprises an electronic circuit at its underside. The electronic circuit is adapted to be at least partially adhered directly to an object, such as a commodity. If the label is removed from the commodity the electronic circuit remains at least partially sticking to the commodity, so that the label has no longer a functional electronic circuit. Product counterfeiting by exchanging of labels can thus be detected.

    Date of Patent: June 28, 2005
    Assignee: Schreiner GmbH & Co., KG
    Inventors: Reinhard Surkau, Klaus Dargahi, Karin Hentsch, Markus Rubekeil
