Definitions

  • the invention relates to a method and devices for checking security documents according to the preambles of claims 1, 9 and 13.
  • a variety of methods, devices, methods and test systems for determining the authenticity of security documents, for monitoring usability, for determining the position in processing machines and for determining types and Counting is known.
  • DE-PS 1223594 describes a device for capacitive scanning of record carriers, in which the scanning capacitors consist of sensor electrodes arranged on both sides of the record carrier web. The scanning security of this device is not given with regard to inserted, pressed or applied electrically conductive strips, tapes or other particles.
  • DE-PS 1774290 describes a measuring arrangement for the automatic evaluation of a characteristic feature of a bank note in a device for checking the authenticity of bank notes by means of capacitive coupling of electrodes which are arranged in a grid.
  • This known measuring arrangement does not allow an exact determination of the relevant characteristic at the processing speeds required under today's conditions, and even with a slow test method, only the presence of such a characteristic is ascertained and thus does not do justice to the currently known counterfeits using electrically conductive components, for example in banknotes.
  • DE-OS 2619457 magnetic properties of a test strip located in a bank note are measured.
  • DE-PS 2834287 describes a genuineness test of ferromagnetic security threads in security prints with exposure to a magnetic field. These test methods are too slow and each require an exact positioning of the test object or the test strip.
  • DE-PS 2760165 describes a technically complex test device in which the authenticity of banknotes is determined in particular in the second test section by measuring differences in thickness and fluorescence properties. The examination of only these properties no longer corresponds to the status of the false certificates in circulation. Counterfeit money with watermarks and fluorescent paper or paint can no longer be recognized as false with this device.
  • DE 43 25 027 describes a method and an arrangement for checking the authenticity of banknotes, the field strength change occurring when a high-frequency field is bridged by a metallic security strip being evaluated. Due to the low sensitivity and the low interference suppression, the use in money counting machines is only suitable at low speeds. Furthermore, even conductive and moist test objects are recognized as real. Breaks in the metal strips of real banknotes are not recognized, so that the machine stops incorrectly. Due to the low sensitivity of the arrangement, the distance between the electrodes and the metallic security thread of the banknote must be very small, which prevents use, particularly in high-speed banknote processing machines. A series of such sensors is only possible with a relatively large distance between them so that the sensors do not influence each other.
  • WO 94/22114 describes a device for detecting metallic conductive security threads.

Since conventional copying machines can already be equipped with magnetically conductive ink, this type of test is very limited in its reliability with the quality of the counterfeits today.
  • a disadvantage of the Known measuring arrangements for testing the capacitive properties is that only in the provided low frequency ranges from 10 to 220 kHz and only in very small Distances between the electrodes and the metal thread a sufficiently small capacitive Resistance is reached.
  • the influence of the dielectric change is still very large, that is, a substance with a large Dielectric constant leads to an increase in capacitance and thus to a decrease in capacitive resistance between the antennas. For example, a damp one False certificate can be recognized as genuine.
  • these arrangements have, in particular in machine authenticity testing, not yet proven.
  • EP 589 195 A2 describes a method in which to check the authenticity of Test objects over a by scanning a scanning area with highly permeable Magnetic elements obtained detection signal using a device Excitation coil and sensor coil an assignment code is obtained and the authenticity Agreement of detection signal and assignment code is affirmed.
  • This test procedure is only limited for plastic cards with magnetic or magnetizable particles, Paper documents and only a few non-European banknotes can be used.
  • Test methods as described in EP 204 574 A2, 553 402 A1 and 560 023 A1 be in which geometric and / or physical properties of test objects in Comparative methods are classified only for one type of test Object can be used, very complex and have in practice for processing machines because of the required high speed as the only test method for authenticity in not enforced in a processing cycle.
  • the object of the invention is to eliminate the existing disadvantages of the known test arrangements and methods and to propose a method with which a reliable detection of a characteristic test feature is possible, for many types of banknotes and currencies, for example even when moist or deliberately moistened and / or dirty test objects can be used, can differentiate between them, requires little technical effort, the application of which is suitable for retrofitting in processing machines and corresponds to the rapid throughput of test objects in processing machines.

  • An example of such a security document are today's US banknotes, which carry electrically conductive but mutually insulated labels on their security thread. In today's practice, it is necessary to easily install such test systems in processing machines that not only recognize falsifications of high quality as such, but also real documents of inferior quality, since these occur quite frequently in practice and lead to false triggers that affect the operating sequence of processing machines significantly disrupt.

  • the output pulse of the evaluation electronics is independent of the throughput speed.
  • a selective amplifier is additionally coupled to the evaluation electronics. The selective amplifier converts the voltage arriving from the test sensor system into an easily comparable voltage, which depends on the amplitude profile of the incoming voltage.
