Definitions

  • the present invention relates to a device for counting smart cards, or also memory cards, contained in a batch, preferably even contained in a sealed box. It finds more particularly its application in the field of electronic payment. Its main advantage is to increase the security of the counting, during the manufacturing and distribution of cards, both in terms of the accuracy of the number of cards counted and the handling of cards in this batch.
  • the security constraints that must be observed for counting are, on the one hand to obtain an ideally zero counting error rate, and which in practice must be better than the millionth.
  • the metering must be reliable, that is to say that it must not reintroduce into itself the risk of error during handling which could depend on the metering operator. In fact, there is always a risk of fraud as soon as in a manufacturing system human stakeholders are required to handle the cards.
  • the counting must be rapid in order to be able to be carried out at the end of each of the different manufacturing stages and over the whole of the manufacturing, without affecting only a sampled part.
  • the number of cards manufactured in a manufacturing unit can be of the order of several million per month and it can be accepted that it is necessary to count them at least three times during the manufacturing cycle. We therefore imagine the problem represented by this operation.
  • results are obtained that are better than ten millionths, that is to say that the errors can be considered as zero on a production of one month. It is interesting to note that the invention makes it possible to keep the batch of cards in its packaging at the time of counting: this considerably limits the risks of fraud. You just have to choose a package that is transparent to X-rays or to light. Any PVC box may for example be suitable.
  • Lots 3 are placed on strip 6 so that the plane of cards 1 or 2 is substantially parallel to the main direction of the 7 X radiation from the tube 5.
  • the vertical nature of the cards was important but that the device was relatively tolerant in this respect.
  • a hundred cards leads to a thickness of the batch of the order of 8 cm, that is to say of the order of 10% of the difference between the batch and the source X.
  • the device also comprises, below the conveyor belt 6 an X-ray detector.
  • This X-ray detector in one example, consists of a radiosensitive film 8, the photographic printing of which is carried out by an X-ray pulse emitted by the tube 5.
  • a set of lines such as 10 of opacification are observed on a photograph 9 which materialize by their presence the number of cards such as 1.
  • a source of ultraviolet radiation 11 (or of another type of visible optical radiation) illuminates the photograph 9 opposite which a camera 12 is placed.
  • the camera 12 is constituted by a bar 12 of CCD type cells .
  • This bar 12 is connected to a control circuit 13 essentially comprising a clock H capable of causing the transport of loads contained in each of the cells to neighboring cells.
  • the last cell is connected to a signal output of the device.
  • the bar 12 delivers a signal S 14 whose temporal representation, at the rate of the clock H, is in the form of a sequence d impulse 15. Depending on the nature of the image, positive or negative, we will count the peaks or the zero crossings of the signal S.
  • the signal S is introduced, possibly after fitness filtering, in a logic counter 16.
  • the counter 16 has a reset reset input.
  • the counter 16 can also include a display device 17 for the quantities counted.
  • a screen 18 intensifier of radiological images coupled to a television camera 19.
  • the pair screen 18-camera 19 is placed under the conveyor belt 6 at the place where the film was placed 8.
  • the slab 18 of the radiological image intensifier screen is capable of transforming the X-rays received into light radiation.
  • Such screens 18 have been known and used in the medical field for a very long time.
  • Such a slab essentially comprises crystals of cesium iodide capable of making this X-visible light transformation.
  • the television camera 19 reads the transformed image on the reverse side of the screen 18, and delivers a video signal comparable in all points to the signal 14 delivered by the bar 12. It is possible to carry out directly on the video signal. counting indicated previously.
  • the counter 16 is synchronized either with the camera 19 or with the bar control circuit 13.
  • a synchronization link 22 connects the circuit 13, or the camera 19, to the counter 16.
  • the camera 19 can be connected to an image memory. Reading the image memory then provides the signal S.
