Abstract:
1. A method for checking authenticity and/or nominal value of documents of value with luminescent feature substances, comprising the steps: illuminating the document of value to be checked along a plurality of measuring tracks extending across the document of value thereby exciting the luminescent feature substance to emit luminescence radiation; measuring the luminescent radiation emitted by the luminescent feature substance of the illuminated document of value along the plurality of tracks; determining a plurality of measured values of the luminescence radiation emitted by the luminescent feature substance of the illuminated document of value along each of the plurality of measuring tracks; integrating the measured values for each of the plurality of tracks; and checking the authenticity and/or the nominal value of the document of value on the basis of the integrated measured values for each of the plurality of tracks, wherein the luminescent feature substances are checked and are incorporated in and/or applied onto the document of value in random distribution.
