Abstract
A sensor and a method for checking documents of value are provided with a radiation source for applying electromagnetic radiation to a document of value and a detector for position-resolved recording of the electromagnetic radiation emerging from the document of value in at least two different spectral ranges. A first feature of the document of value is checked with the aid of the detector signals generated for at least one first spectral range, and a second feature is checked while taking into account the detector signals generated for at least one second spectral range. The electromagnetic radiation recorded by the detector, or the detector signals of the detector, are attenuated color channel-specifically, an attenuation being performed in the first spectral range relative to the second spectral range. A sensor system and a document of value processing device are provided employing the sensor and/or method.
