Problems solved by technology

[0006] However, it has been found that the measurement sensitivity of these known systems is low, especially if the characteristic substances with low luminous intensity incorporated into the document of value are not concentrated locally but are distributed over a large surface

Embodiment Construction

[0017] Although the verification device according to the present invention can be used in all banknote processing machines, such as deposit machines, vending machines or hand-held verification devices, by way of example and with reference to figure 1 Describe the application in banknote sorting machine 1, figure 1 Shown in schematic side view.

[0018] The bank note sorting machine 1 comprises, in a manner known in the art, an input container 3 into which bank notes BN to be checked are inserted in stacks. The bank notes are individually removed from the stack by means of a picker 4 and transported past the checking device 2 along a transport path 5 . The testing device 2 has an EDP auxiliary evaluation unit 6, which is connected to an illumination device 7 for exciting the luminescent characteristic substance 15 on the banknote paper and a sensor device 8 for detecting the luminescence, as well as a light barrier 10. For luminescence radiation, the light barrier 10 is locat...

Abstract

The invention relates to a device and a method for authenticating a value document with a luminescent characteristic substance. An evaluation of the detected luminescence radiation based on an integrated luminescence measurement obtained by integrating the measured luminescence radiation over a track extending transversely to the value document makes it particularly easy to detect and distinguish weakly luminescent characteristic substances.

Description

technical field [0001] The invention relates to a device and a method for verifying the authenticity and / or face value of a value document bearing a luminescent characteristic substance, wherein the value document is illuminated with light and the luminescent radiation emitted by the value document is captured to determine the Whether the desired luminescent characteristic substance is actually present in the value document being checked. Background technique [0002] Within the scope of the present invention, a luminescent characteristic substance is a substance consisting of a single component or a mixture of components which exhibit luminescent properties. These characteristic substances, for example in the form of pigments, are contained in the value document itself and / or are applied to the value document. Such documents of value may be banknotes, cheques, chip cards, identity documents, passports and the like. [0003] There are many known systems for verifying such ...
