Security element structure for documents, devices for checking documents with such security elements, method for the use thereof

The invention relates to bill anti-counterfeiting factor's key, an and a anti-counterfeiting element device, and according to method for use of DE19718916.4. The head of the present invention improving is anti-counterfeiting element for bill a anti-counterfeiting, and providing detecting centre of the anti-fake element device, wherein claims a new method of using anti-counterfeiting element and device; the method can not is made of false layer is hard, and is impossible made of sham, wherein a closed is the original part, the impossible measuring to the connecting preventing to the manner of with the detecting device for testing method and detecting work. The paper anti-counterfeiting element structure design method when mounting seat of the test method with emphasis, and a wireless of the observing of vision. The designs, compromised of the is a function, design is a conductance and a insulating or similar different-face size and a or similar to different plane, same or different conductivity the combination of structure. The inventive structure design of the metallic structure and/or conductive ink or the colour printing ink production.
