Abstract
The invention relates to an application and a method for checking documents. Hitherto, documents with optical diffraction security layers, specially holograms, were checked by costly optical monitoring technology. The entire monitoring process was so time-consuming that the monitoring process could not be applied to fast operating processing machines. Rapid monitoring (as an authentication characteristic) constitutes a further security step in evaluating effective optical diffraction security layers. The effective optical diffraction layer has a discontinuous metallizing layer and/or partially metal layers and/or areas of metal layers on various planes. Several methods of measurement exist to detect electrical conductivity. In practice, the contactless capacitive method of measurement has proven to be more practical.

This invention relates to a use of and a method for testing of documents.
ro date, documents with diffraction-optically effective safety layers, in particular holograms, have been tested with costly optical testing equipment. In these procedures, the test object has to be positioned very exactly. The entire testing process takes so long that these test procedures cannot be used in. high-speed processing machines.
Testing of, for example, banknotes with a hologram authenticity feature in a banknote counting. machine is impossible, as it runs at high speeds between 500 and banknotes per minute and above. A method and device of forge testing holographically protected identity cards is disclosed in Di= 27 47 156. The hologram is reproduced and a visual check is carried out. This method is not suited to high-speed, efficient, person-independent testing. A device for generating scanning patterns which are tested by means of laser, mirror and lens system as well as a photodetector is described in EP 0 042 946. The economic expenditure is also in this case very high. It would increase further if the test objects are to be tested without prior sorting, To avoid presorting, the forge test system would have to be arranged several times_ It is the object of the invention to eliminate the disadvantages of the prior art and to propose a use, and a method of testing, of documents with diffraction-optically effective safety layers, in particular holograms, which can be tested rapidly, person~independently and inexpensively.

This problem is solved by the futures given in the characterizing clause of claim 1.
Holograms and other diffraction-optically effective safety layers for the protection of certificates and other securities as well as banknotes against forging are now used more and more widely- Rapid testability is another safety stage in the valuation of diffraction-optically effective safety layers as a fEature of authenticity. Diffraction-optically effective layers are composed of a metallized layer, among other things. This metallization IayEr is electrically conductive. The electrical conductivity changes with the thickness of the layer. The diffraction-optically effective layer has a discontinuous metallization layer andlor partially metallic layers andlor zones of metallic layers in different planes. Various measuring methods to determine an electrical conductivity are known. In practice, the non-contacting, capacitive measuring method has proved useful. This method of testing safety documents utilizes the capacitive coupling between transmitter and receiver and ....
the transfer of energy between transmitter and receiver by bridging an electromagnetic field by electrically conductive safety materials. A downstream electronic evaluatibn system compares the signal picture of the test object with relevant reference signals.
The comparison provides a classifying signal for reprocessing. Therefore, a document detected as a forgery, for example, could be sorted out by stopping the test device. The signal picture depends on the structure of the metallized layer of the diffraction-optically effective layer. If the diffraction-optically effective layers have a discontinuous metallization layer, several segments of the metallization layer have different electrical conductivities. Practice has shown that these different conductivities have an effect on the signal picture.

The application of additional authenticity features into demetallized segments within discontinuous metallization layers andlor partially metallic layers andlor between zones of metallic layers in different planes allows the simultaneous testing of these features with the electrical conductivity.

Therefore, an optical or magnetic sensor is used. To reduce detecting and measuring errors, a sensor carrier is used preferably.
