Definitions

  • the present invention relates to a test device for checking the authenticity of a valuable medium, in particular a banknote, a bank card or a credit card, with a sensor having a test surface for checking physical or chemical properties of a valuable medium.
  • the valuable medium is a bank card
  • such devices are needed, for example, in ATM card readers in order to prevent a fake bank card from being used.
  • This is particularly important because criminals have recently been increasingly able to use so-called "skimming devices" to spy on data from third-party magnetic strips and use them on a counterfeit card in order to gain access, for example, to the third party's account , Therefore, there is a need for a device for verifying the authenticity of bank cards.
  • the stated physical or chemical properties which can be checked with the sensor include in particular optical, spectroscopic, electrical or magnetic properties of the valuable medium which can not readily be reproduced by a counterfeiter.
  • Such properties that can be checked by the sensor are generally referred to herein as a "safety feature" of the valuable medium.
  • they are security features that are present on the entire surface of the valuable medium.
  • the valuable medium is guided past the test surface of the sensor and the sensor checks the portion of the valuable medium opposite the test surface.
  • this results in a narrow, straight running track, in which the valuable medium is checked for authenticity.
  • FIG. 1 The area of the banknote 10 which is checked by the sensor is shown as sensor curve 12. Since in such a device according to the prior art only the narrow strip along the sensor track 12 is checked, criminal persons have come up with the idea to fake the bill 10 by only a narrow strip 14 (shaded area in Figure 2) from a genuine bill is used, which is supplemented with fake material to a fake bill. If the security feature is a feature that covers the whole area of a real one In this case, a true medium can be cut into a plurality of strips, from which counterfeit media can then be produced, all of which would be recognized as genuine by the prior art device.
  • the invention has for its object to provide a test device of the type mentioned above, which significantly increases the security of authenticity testing of valuable media such as banknotes in particular when using sensors with small area test area.
  • test device comprises a sensor which is arranged movably relative to the transport device for the transport of the valuable medium.
  • the movable arrangement of the sensor can be achieved with very little design effort, so that the cost of the device is not significantly increased.
  • the senor movement is a periodic movement, in particular a circular movement.
  • a circular motion can be relatively simple and inexpensive and thereby wear.
  • the deviation of the sensor tracks in the case of two valuable media to be checked one after the other can be generated in a simple manner by a phase difference in the periodic movement.
  • the device comprises a sensor arrangement 2 and a transport device 3 for the transport of the bill 1 past the sensor arrangement 2.
  • the transport device 3 is designed, for example, as a belt transport consisting of three transport belts or transport belt groups 18, 20 and 22, which are each tensioned between two rollers 24.
  • the leading end of the bill 1 is held between the belt 20 and the belt 22 and the trailing end of the bill 1 is held between the belt 18 and the belt 22.
  • the distances between the belts and between the bill and the belts are shown enlarged in the schematic of Figure 1 for the sake of clarity).
  • test surface refers in particular to a surface section of the valuable medium, which is opposite the sensor and can be checked by the sensor.
  • the sensor arrangement 2 comprises an electronic control unit 40 for activating the motor 30, which sets the horizontal disc 36 and thus the sensor 38 in a rotational movement.
  • the bill 1 is transported at a speed v in the direction of the arrow 26 until the leading end of the bill 1 faces the test surface of the sensor 38.
  • the sensor 38 can only check the portion of the bill 1 opposite the test surface. Since both the bill 1 and the sensor 38 moves, depending on the rotational speed of the disc 36 and the distance of the sensor 38 from the rotation axis sensor tracks 12 as shown in Figures 3 to 6 by thick black lines.
  • different sensor tracks 12 can be provided for each banknote. In the present embodiment, this results from a phase shift between the sensor tracks 12 in successive bills.
  • the phase track 12 is shown in a bill 1 which has been checked immediately after the bill 1 of Fig. 3, i. without the sensor 38 having continued to rotate between the two verification operations. Since the time duration of the checking operation (i.e., banknote length / v) in the embodiment shown is not an integer multiple of the period of the circular motion of the sensor 38, a different sensor track 12 results for the subsequent banknote 1 of FIG. 4 than in FIG.
  • sensor tracks 12 are shown in which the angular frequency ⁇ of the circular movement of the sensor 38 has been increased to 4 times or 2 times compared to the sensor tracks of FIGS. 3 and 4. It is clear from these figures that different areas of the bill 1 with the sensor 38 can already be checked by a suitable choice of the angular frequency ⁇ of the sensor movement.
  • the electronic control unit 40 controls the motor 30 in such a way that the sensor track 12 passes over predetermined sections of the banknote 10, on which isolated security features are formed.
  • the electronic control unit 40 can control the motor 30 such that the initial phase value ⁇ of the sensor relative movement is adjusted, the frequency ⁇ of the sensor movement is varied and / or the direction of movement of the motor 30 is reversed.
