Description

The invention relates to a security element containing a unit forming a transponder from one miniature electronic circuit and an electrical Winding that is electrically connected on or are arranged in a common carrier, the Transponder for its identification with an external one Reader can be coupled. The invention also relates to its use as a forgery-proof label or Seal.

Transponder elements of the known type are known (WO 87/04900). Due to the properties of the transponder can the object provided with the transponder element, for example a living being, like a fish, at the Passing an external reader identified become. Because of the variety of coding options of the transponder via the in the miniature circuit stored data code results in a high number of different identification options.

A transponder component as it is known from EP 0 573 469 is known, characterized in that the Miniature circuit and the winding just over the winding wire ends that are connected to each other metallic conductor tracks of the miniature circuit are welded or soldered. The so made  The unit consisting of circuit and winding then becomes housed on or in the carrier. Come as a carrier all types of non-conductive materials, in particular Glass or plastic, in question.

Transponder elements of the type mentioned are in practice due to the comparatively high so far Production costs only used where the Investment expenditure justifies this, for example in Connection with key facilities for cars, at a mutual one by means of the transponder element Authentication of keys and in the vehicle attached control unit takes place. Because of the essential larger number of different possible combinations such locking devices are conventional mechanical keys.

On the other hand, security elements are known that are or on the object to be secured or as real object to be occupied are firmly attached. Examples are security labels for clothing that only by an authorized person inside the department store are detachably attached to the garment and at unauthorized leaving one in the exit area of the Department store-trained electrical resonant circuit detune so that an alarm signal is triggered.

Also for authenticity documentation of banknotes or credit cards known holographic elements that due to their microscopic diffraction structures have high security against counterfeiting.  

DE 41 10 683 A1 is a securing element in the form known a transponder, which u. a. in the function is used as an anti-theft marker. The Transponder consists of one with a circuit connected sink with flat winding. The Transponder has predetermined breaking points, which at one Detach attempt to break apart in a mosaic, so that the Function is completely destroyed.

DE 37 32 297 A1 describes a monitoring system for Movable objects known, the detuning a resonant circuit contained in the transponder is achieved that as a result of a weakening of the Target weakness area the connection of two in parallel switched resonance circuits is canceled.

Based on this, the object of the invention is to create a security element which, on the one hand has the greatest possible level of security against counterfeiting and on the other hand is inexpensive to manufacture.

This task is done with a security element comprising a unit forming a transponder a coil with one on a core Winding and a miniature circuit that is conductive with the coil connected on or in a common carrier is arranged, solved in that the coil and Miniature circuit formed resonant circuit in a row through the weakening in the target weakening range caused breakage of the core is so detuned that this can be detected by an external reader.  

The invention is characterized in that at one Manipulation process the security element in this regard is charged that a break in the predetermined weakening range entry. The break causes a permanent change the resonant frequency of the through circuit and coil formed resonant circuit compared to the undeformed Status. A corresponding to the resonance frequency matched reader can thus Detect manipulation process. Preferred application finds this variant of the invention in such Transponder components where the coil is a solenoid is formed with the solenoid on a core is wound up. If the core of the solenoid in the area the predetermined weakening point is arranged, this breaks in the case of a load caused by manipulation due to its brittleness, which makes the Resonance frequency of the solenoid and circuit formed resonant circuit changed.

A particularly cost-effective construction results if the transponder is a READ ONLY transponder. Based on Each individual can store data stored in the transponder Security element to be identified. Because of the The variety of coding options is effective practically every single security element is unique

A security element with further increased intelligence results from the fact that the transponder is a WRITE / READ Is transponder. In addition to the readable Identification data can be added to the transponder Data are assigned, for example one external database. The data will with an external read / write device in the transponder saved.  

A preferred embodiment results from the fact that on or in the carrier another Identification element is arranged. The further Identification element acts independently of the Predetermined breaking area assigned first Identification element, so that the further Identification element even after destruction in the Predetermined breaking area remains functional. As a result the possibility that the damaged security element can still be identified.

The variety of possible uses continues thereby increased if the further transponder element too READ / WRITE transponder.

Preferred uses of the solution according to the invention are listed optionally in claim 1.

The invention is based on a Embodiment explained in more detail.

The single figure shows an embodiment according to the invention. For this purpose, the figure shows a carrier 1 , which has a surface area 1 a and an adjoining web-shaped area 1 b.

A ferrite core 4 is arranged within the web-shaped area 1 b and extends beyond the area of the desired weakening 1 c.

In the head region of the land region 1 b, a winding 2 in the form of a solenoid is arranged on the ferrite core, the ends of which are connected to a miniature circuit 3 . The connection between the solenoids 2 and the miniature circuit 3 takes place according to the method known from European patent specification 0 573 469.

The resonance frequency of the resonant circuit thus formed is determined, among other things, by the magnetic properties of the ferrite core 4 . If the object shown in the figure is now loaded, a deformation preferably occurs in the predetermined weakening area, as a result of which the ferrite core 4 breaks due to the brittleness of its material. This changes the resonance frequency of the transponder component.

On the one hand, this change is irreversible and, on the other hand, it occurs even if the unit consisting of coil 2 and miniature circuit 3 is retained as such, so that the function of the transponder element in principle is retained.

Is now using a tuned receiver the resonance frequency of the transponder component detected, the difference between the broken and unbroken ferrite core through the measured change in the resonance frequency is detected become.

In this way the manipulation process is discovered.
