The present invention describes sheet material having an electrical circuit as well as apparatuses and methods for processing same, which reduce the effort required for processing the sheet material and/or facilitate processing and/or improve it and/or make it more reliable. For this purpose, the sheet material has at least one electrical circuit, with energy and/or data being transmitted from the apparatus to the electrical circuit and/or from the electrical circuit to the apparatus and at least part of the transmitted data being used for processing.

Abstract: The invention relates to a value document, such as a banknote (1), which includes one or more window zones (2A, 2B) with one for example optically active element each which rotates a polarization plane P0 of polarized light LA, LB, penetrating the window zone by a defined angle. If such value documents are stacked and polarized light penetrates the superimposed window zones, the number of stacked value documents can be determined by way of the overall rotation of the polarization plane PA, PB. The overall nominal value of a stack of banknotes can thus be determined. The window zones can have category-specific rotational characteristics for different categories or nominal values and/or can be disposed in category-specific positions in the valuable document.

Abstract: The invention relates to a document of value, such as a paper of value, ID card or the like, having at least one authenticity feature in the form of a luminescent substance. The luminescent substance has particles consisting of a dye-laden molecular sieve whose structure forms an optical resonator. In said resonator at least one dye can be excited to show stimulated emission, the dye being incorporated in the cavities of the molecular sieve or located in or on the internal and external surfaces of the molecular sieve, and the transition to stimulated emission being accompanied by a detectable change in the luminescent properties of the dye.

Abstract: An apparatus and corresponding method for examining document having at least one excitation device for exciting luminescence light in or on a document to be examined and at least two detector units for detecting at least part of the luminescence light emitted by the document. To increase the reliability of examination of the spectral characteristic of the luminescence light, it is provided that the detector units are disposed one behind the other with respect to the luminescence light emitted by the document. This causes the luminescence light to successively hit the detector units and be detected thereby. The apparatus and method permit any parallactic errors, which occur particularly with a laterally shifted arrangement of detector units, to be greatly reduced so that the detector units can detect the luminescence light emitted by a common partial spatial area of the document.

Abstract: The invention relates to an apparatus for examining documents, in particular documents of value, identification or security documents, having at least two detector units (1, 2, 3) for detecting light (16) emanating from a document (10) to be examined. To increase reliability when examining luminescence, reflection and/or transmission properties of documents, a scattering element (5) is provided on which the light (16) emanating from the document (10) is scattered, the scattering element (5) and detector units (1, 2, 3) being disposed such that the scattered light can be detected by the detector units (1, 2, 3). The scattering element (5) causes spatial mixture and homogenization of the light (16) emanating from the document (10) so as to greatly reduce any parallactic errors that occur in particular with detector units (1, 2, 3) disposed side by side.
