  • Patent number: 12384190
    Abstract: A value document with a carrier element and a foil element arranged in a partial region of the carrier element. The carrier element has, at least in the partial region, a luminescence marker which is adapted to give off luminescence radiation which has at least a first wavelength and a second wavelength in each case in the infrared spectral region. The foil element has a reflection layer and a spectral selection layer. The selection layer is arranged between the carrier element and the reflection layer. The reflection layer is configured to reflect infrared radiation and the selection layer is configured to spectrally selectively inhibit transmission of infrared radiation. The inhibition of the transmission of the first wavelength and the inhibition of the transmission of the second wavelength differ by at least 10%.

  • Patent number: 12159504
    Abstract: A method for checking value documents involves the steps of: irradiating, by an excitation device, a first side of the value document with excitation radiation for exciting luminescence of a luminescent substance on the value document, such that the first side is a back side of the value document, capturing luminescence radiation which was excited by excitation of the luminescent substance at a front side of the value document by at least a part of the excitation radiation after transmission through the substrate of the value document and exits the value document at least partly at the back side of the value document after transmission through the value document, by a capture device, and checking the value document in dependence on at least one property of the captured luminescence radiation by means of an evaluation device.

  • Patent number: 10144242
    Abstract: A method for checking the authenticity and/or the nominal value of a value document having luminescent feature substances, comprises: a1) the step of carrying out a location-specific measurement of first luminescence intensities (L1) at a first emission wavelength at different locations of the value document that have the location coordinates (O), to thereby obtain (O/L1) measurement value pairs; b1) the step of statistically analyzing the first luminescence intensities (L1) measured in dependence on the individual location coordinates (O), by determining at least one statistical parameter using a statistical method; and c1) the step of comparing the statistical parameter determined in the step b1) with one or more threshold values.

  • Patent number: 10109133
    Abstract: An apparatus, a corresponding method, and value-document processing system for checking value documents that has at least two radiation sources for giving off electromagnetic radiation with which a value document is irradiated, at least one sensor for capturing the electromagnetic radiation emanating from the value document, and generating corresponding sensor signals. The apparatus has an evaluation device configured to derive from the sensor signals corrected sensor signals taking into account at least one spectral property of the electromagnetic radiation of the at least two radiation sources. The sensor signals corrected in this way reproduce the actual reflection or transmission behavior of the value document substantially more precisely than the uncorrected sensor signals. Disturbing remission or transmission artifacts may be attributed to so-called auxiliary emissions of the radiation sources are eliminated or at least reduced.
