Abstract: A method for automatic processing of sheet material, e.g. bank notes, wherein the bank notes are singled, transferred to a transport system, tested, and stacked in units of a predetermined piece number in so-called stackers by predetermined categories in accordance with the testing. The transfer of bank note to the transport system is interrupted as soon as the sensor unit ascertains that the predetermined piece number of a category is reached in a stacker. The bank notes of the same category already singled at this time are stored temporarily in the sorting plant until the stacker has processed the deposited predetermined piece number.

Abstract: The invention relates to a data carrier comprising a one- or multilayer card body in which an electronic module is embedded. The layers of the card body consist of paper and/or cardboard and are interconnected for example by thermally activable adhesive or contact adhesive. The cards can be produced by continuous technology, the individual card layers being supplied from endless rolls, provided with the necessary windows for receiving the modules, and finally interconnected. The modules are inserted in the resulting gaps. The individual cards are punched out.

Abstract: The invention relates to a data carrier comprising a card body and an integrated circuit connected electroconductively via contact elements with at least one coil serving the purpose of power supply and/or data exchange of the integrated circuit with external devices. The invention is characterized in that the integrated circuit and the contact elements form a separate module known in the art and the coil is disposed on a card body constructed from one or more layers in known fashion. The coil is preferably formed as a flat coil.

Abstract: For testing the intactness of stored data, intact data corresponding to the data to be tested from a component of the processing facility in a certain operating state of the processing facility in the intact state are first stored in a test device. To check the intactness of the data to be tested in a component a key is produced in the test device for each test, said key being different from those of prior tests. Using this key and a cryptographic algorithm one prepares two cryptograms. One cryptogram is prepared from the data to be tested by the component of the processing facility in which the data to be tested are stored. The other cryptogram is prepared from the intact data by the test device. After that the two cryptograms are compared with each other. If the cryptograms match, the data to be tested match the intact data and thus have no undesirable changes.

Abstract: The invention relates to a coil element for a data carrier with an integrated circuit and noncontacting coupling and to a method for producing it. The coil element includes a carrier film or layer (6) and a wire-wound coil (2) fixed to the carrier layer (6). The carrier layer (6) serves to mechanically stabilize the wire-wound coil (2) and becomes part of the card body during production of the data carrier, for example an IC card. The coil (2) is fixed to the carrier film (6) during the winding process or directly following the winding process. The winding process and the apparatus used therefor are designed so that a plurality of coils (2) can be wound and fixed on a common carrier layer (6) simultaneously.

For filling the remaining cavity after installation of the module in the gap, one provides on a layer adjacent the gap or on the layer containing the gap or directly on the electronic module a material preferably applied by printing technology and having a softening point lower than the softening point of the layer.

Abstract: A method for testing the authenticity of a data carrier having at least an integrated circuit with memory units and logic units as well as a data line for data exchange with an external device. The invention is characterized in that the integrated circuit additionally has a separate hard-wired circuit for transmitting and/or receiving data during the power-up sequence, which is used for authenticity testing, the first transmission or reception of data being completed within a defined time domain of the power-up sequence in which the data line has no defined state.

Abstract: A lead frame module to be incorporated in data carriers is presented which is divided into two areas, namely a central area receiving the sensitive components of the module, and an outer area protruding beyond the edge of the central area and serving to glue the lead frame module to the data carrier. To prevent forces from being transmitted from the outer area of the electronic module to the central area upon bending loads of the data carrier, the outer area is decoupled mechanically from the central area. This can be done for example by providing partial discontinuities including relieving punchings in the transition between the central and outer area.

Abstract: A security document such as a bank note, identity card or the like, includes at least one multilayer security element made of at least two layers of reaction lacquer or adhesive between which diffraction structures, in particular holographic structures, exist in the form of a relief. A reflective layer is additionally disposed between the layers of lacquer. The reaction lacquer of adhesive is the type curable or cross-linkable under physical (e.g. radiation) and/or chemical activation.

Abstract: A method and apparatus for making a data carrier (1) such as a paper of value or the like having an optically variable element (5,6) such as a hologram, applied to the surface, and an additional printed pattern (2), applied for example by steel intaglio printing, wherein the surface of the data carrier (15,16,20,21) is made smoother in the area of the optically variable element than in the remaining surface and the optically variable element is applied to the smoother area.

Abstract: A method for singling loose sheet material, in particular bank notes, wherein the sheet material is supplied in an input pocket in the form of a stack in a defined position for vertical feed of the sheet material to a singler. The sheet material is moved within the input pocket vertically from the feed position to a singling position. While the preceding stack is still being singled in the singler, the next stack to be singled is already supplied in the input pocket of the singler in the defined feed position.

Abstract: An antifalsification paper is described having an embedded safeguarding thread which is embedded in the paper so as to be freely accessible in some areas. The safeguarding thread has a width greater than 2 mm. The antifalsification paper comprises at least two paper layers produced on separate paper machines. The safeguarding thread is embedded in the first paper layer which has openings or recesses in its surface through which the thread is partly accessible on both sides. This first paper layer is covered with at least one second paper layer and firmly connected therewith, the second paper layer having a thickness of 10 to 50%, preferably 20%, of the total thickness of the antifalsification paper. The use of particularly wide safeguarding threads and the resulting possibility of equipping the threads with certain optical effects can improve the resistance to forgery of the antifalsification paper provided therewith.
