On a check card having a mini chip card disposed detachably in an adapted recess the mini chip card is fixed in position by at least one fastening element provided on the card surface. After a first punching operation in which the mini chip card is still connected with the card body by bridges the fastening element is preferably placed on the card in such a way that it bridges the areas between the mini chip card and the card body. In a second punching operation the bridges are removed, after which the mini chip card is held in its original position on the card body only by the fastening element.

A security element for use in a security document such as a bank note, identity card or the like includes at least a partial metallic coating on a substrate and wherein the metallic coating includes recesses in the forms of characters or patterns that are visually recognizable at least in transmitted light and a magnetic coating of soft-magnetic pigments disposed in overlying relationship with the metallic coating. A security document containing the security element is also described. Various arrangements of metallic and magnetic coatings and a method of producing the security element are also described,

The invention relates to an optical sensor system, in particular for detecting diffuse low-intensity radiation as occurs in testing bank notes provided with luminescent features. In a preferred embodiment the sensor system comprises a flared optical fiber pipe and a processing optical system, whereby the narrow cross-sectional end of the fiber pipe can be used to detect the radiation from the test object at a large solid angle. Due to the change in cross section this radiation emerges from the fiber pipe at a much smaller angle that is coordinated with the aperture angle of the succeeding optical system.

The invention relates to a security document, in particular a bank note, identity card or the like having a security element which is provided with characters, patterns, etc., visually readable at least in transmitted light and which is electrically conductive and bears additional substances for machine testing, and to a method for producing such a security element. The security element comprises a transparent film strip that bears negative writing readily capable of visual checking and is additionally provided with electrically conductive and magnetic substances.

A recording medium is provided with picture information in a tamper-resistant and high-resolution form. The picture information is broken down into a light/dark portion and a color portion. The light/dark portion needed for the visual impression is incorporated in the recording medium in a high-resolution form. The colored picture information is congruently superimposed on this portion so as to produce an integral ensemble. Protection from falsification is ensured by incorporating one of the portions of the picture information in the card structure in largely tamper-resistant fashion.

A security element that can be embedded in the form of a thread or strip in a security document, in particular a paper of value, is composed of two carrier sheets, each of which bears each of the marking substances allowing for detection of authenticity. The two carrier sheets are put together in such a way that the marking substances to be protected from mechanical abrasion and other external influences come to lie on the inside.The thread not only offers special protection for the marking substances, but can also be embedded in the paper substance easily due to its symmetrical structure and without showing any tendency to curl.
摘要:
In a security document having an embedded security element in the form of a transparent thread with electrically conductive material in at least two layers, at least one layer is transparent or partly transparent at least in certain areas. The partly transparent layer interacts with marks located on the thread in such a way that the marks are largely concealed in incident light but are recognizable visually in transmitted light.

A carrier element is described that has one or more ICs to be incorporated into an identity card or credit card. The carrier element comprises a substrate having on its surface a plurality of contact areas which are connected via connector paths to corresponding terminals of the IC disposed on the substrate. The IC, including the connections to the conductor paths, is protected from mechanical stresses by a cured casting compound. In order to prevent the casting compound from flowing off uncontrollably during its application, an opening is provided in the heat-set adhesive layer applied to one side of the substrate, said opening holding back the liquid resin during its application and acting as a limiting frame. The opening in the adhesive layer is located at least where the IC is to be disposed.

A security document such as a credit card or the like carries an automatically, machine-sensed material adapted to generate reproducible signals unique to such document. The material is arranged randomly along a line-like track and sensed by a scanning head having a transverse sensing slot of much greater length than the track width, whereby reproducibility of the scanning signals is assured. A system for testing the authenticity of such documents includes sensing means for detecting the material of the line-like track and converting it into a corresponding electric signal and a comparator means in which the electric signal is tested as to its identify relative to a signal generated in the same manner during the previous sensing. The electric signal is derived from a verification characteristic of the card which may be intrinsic property of the card material.
