Description

The The present invention relates to a card-shaped data carrier, in particular a chip or magnetic stripe card, with at least a security feature and a method and apparatus for its production.

A card-shaped Data carriers in the sense of the present invention for example, credit cards, debit cards, identity cards, ID cards, phone cards and other cards with security-related Functions are and are in particular cards in ID1 format. such Data carriers can be a card body consisting of a single layer (monolayer card) or one Card body consisting of several layers (multilayer card) have. While with a monolayer card usually the card body of a single plastic film or is made by injection molding of plastic is added a multilayer card usually the card body several plastic films which are laminated to each other, produced, but also the production of multi-layer cards by injection molding is possible.

It is known to provide such security-critical data carrier on its front and / or back with one or more security features to protect against counterfeiting. In particular, the security features can be printed on the front and back and / or embossed. Furthermore, the front or back of the kartenförmigen disk can be provided with a signature strip that allows a signature sample with commercial pens. In addition, magnetic strips and / or electronic chips, on which data, in particular safety information, are stored, are placed on or in the card-shaped data carrier or introduced. This security information can be read with readers, and it is also known to check the authenticity of the card-shaped data carrier by matching the data read with other applied on the disk security information. As a further security feature of the card-shaped disk can also z. B. be provided with a hologram. An overview of various types and formats of card-shaped data carriers as well as methods for producing card-shaped data carriers and methods for generating security features is disclosed in US Pat Yahya Haghiri, Thomas Tarantino (ed.), "From Plastic to Chip Card", Carl Hauser Verlag, Munich, Vienna, 1999 and in Wolfgang Rankl, Wolfgang Effing (ed.), "Handbuch der Chipkarten", 5th edition, Carl Hanser Verlag, Munich, Vienna, 2008 to find.

In spite of of these different security features is an absolute falsification or fake security of the card-shaped data carrier not given. In particular, there are counterfeiting attacks in which individual layers of multilayer cards separated and in fake ones Cards are reused.

task The present invention is therefore anti-counterfeiting security the aforementioned disk, preferably such with multilayer card body, increase.

to Solution of this task becomes a card-shaped Disk with at least one security feature provided at least one of its edge surfaces. In this In addition, a device for generating a such security feature on a card-shaped disk proposed.

The Imitating the at least one security feature on an edge of the disk requires additional devices, which differs from the known devices for generating and reproducing security features on the front or back of a card-shaped data carrier. Furthermore, additional knowledge is required to emulate the security feature of the invention. Thus, by the present invention, the forgery Card-shaped disk difficult.

There in a multilayer card body, the security feature preferably extends over several layers is also a forgery attempt, in which individual films or layers the volume body exchanged or reused become, more difficult, because several layers of the card body have at least one security feature and reuse must be aligned exactly to each other, not as Fake to attract attention.

Of Further allows the inventive Security feature mechanical personalization (eg embossing), without the surface of the card-shaped data carrier to destroy and thereby the mechanical stability of the card-shaped data carrier to reduce. Furthermore, by the at least one security feature on the Edge surface of the card-shaped data carrier may be a security feature on the front or back of the card-shaped data carrier eliminated, giving more space, for example, for design elements or promotional purposes.

For a machine check of the authenticity of the data carrier, the security feature preferably comprises at least one machine-readable mark, for. As a bar code, luminescent Feature substances or light-conducting fibers. Suitable luminescent feature substances are both phosphorescent feature substances and fluorescent feature substances.

The Security feature according to the invention preferably comprises Personalization data, such as serial numbers or in particular personalization data, So personal data of the owner of the card-shaped Disk (date of birth, name, etc.) and / or is available Personalization / personalization data of the data carrier in a testable relationship. This facilitates the test the authenticity of the data carrier. In addition, these data are for a counterfeiter not easily obtainable, and further It represents an increased effort, the cards with different Data or security features to provide, with which the counterfeit security is further increased.

The Security feature of the invention may preferably in a testable relationship with on the front and / or Back of the card-shaped data carrier applied data. In this case, the Check the authenticity of the data carrier by comparing these data. It is on the one hand possible that the inventive Security feature in a testable without special knowledge Relationship with those on the front or back of the disk applied data by, for example, direct Includes representation of identical characters or checksums, thereby checking the authenticity of the data carrier is relieved. Alternatively or additionally, the security feature in a relationship that can not be tested without special knowledge to the on the front and / or back or applied Data is available by this z. B. in encrypted form includes, whereby an imitation of the security feature in addition is difficult. By analogy, the security feature for a machine authenticity check also in a verifiable Relationship to data that exists in a chip or magnetic stripe of the data carrier are stored.

According to one First embodiment, the at least one security feature a caption of the edge of the disk. Suitable for this purpose On the one hand the laser inscription by blackening or burning away (engraving) the card body material as well on the other hand, common printing techniques, such as ink-jet printing, Thermal printing, pad printing or laser printing. So can several card-shaped Disk with little effort with different Customization data, in particular personalization data provided become. In addition, the laser engraving enables the production a tactile security feature, preferably a has characteristic haptics.

Because this increases and depressions in the edge surface of the card body, This embodiment enables generation a tactile security feature, which in turn is preferred has a characteristic feel.

According to one Another embodiment, the security feature during the injection molding of the card body generated, preferably by using a mold that is in the areas that correspond to the side faces of the disk, Elevations and depressions, or by inserting of individual deposits in the mold, the volume-specific Openings in the edge areas of the data carrier produce. Due to the resulting increases and recesses in the edge surface of the card body this embodiment also allows the Generation of a tactile security feature, which in turn is preferred has a characteristic feel. The deposits can also be sprayed on the card body and a part form the edge surface.

A mechanical embossing of the edge surfaces takes place preferably in that the card by means of a transport device on one or more embossing rollers with letters and / or Digits and / or barcodes and / or other symbols along is, wherein the embossing rolls on a in the transport direction extending edge surface are pressed so that they over this edge surface scroll and the letters and / or numbers and / or emboss barcodes etc. in the edge surface. In this case, a variation of the security feature, for example depending on individualization / personalization data, thereby allowing one or more embossing rollers be provided, which are stored and controlled so that They each on both an edge surface of the card-shaped Disk pressed as well as lifted from this can, where by the embossing function of each embossing roll can be activated and deactivated individually or in combination. Instead of or in addition to the embossing rollers are also embossing stamp used.

In order to provide the security feature according to the invention with individualization data / personalization data, the device for generating the individual security feature can have a Input device for inputting the individualization data / personalization data or a read-in device for reading the customization data / personalization data from a data memory and a controller for controlling the device for applying or introducing the individual security feature taking into account the input or read data. The control can be effected, for example, by activating the marking device or by activating / deactivating the embossing function of one or more of the embossing rolls and / or embossing dies.

In order to The security feature in a multi-layer disk over extends several layers of the card body, the Security feature preferably in or on the edge surface applied or applied in such a way that it is perpendicular to the front and back of the disk extending direction over extends at least 50% of the thickness of the data carrier. This In the case of multi-layered cards, the security feature is over extends at least two layers.

Preferably are disks to use, their edge surface have a flat surface, such as disk with straight punched edges, the z. B. in the cutting punching of Fa. Blumer, Otelfingen, Switzerland. That's how it works Applying or introducing the safety feature on or into the edge surfaces, in particular embossing, engraving, printing or other Label, relieved.

The card-shaped data medium 1 is by means of a transport device 40 on several embossing rollers 31 . 33 . 35 . 37 passed by, the transport device 40 a lateral guide 41 which is intermittently interrupted to emboss symbols on the lateral edge surfaces 7 of the volume. The feed force for the data carrier 1 can by means of one or more transport belts, not shown here, the transport device 40 be generated.

The embossing roller 31 for embossing a bar code and the embossing roll 33 for embossing numbers are on the edge surfaces 7 of the disk 1 pressed them so that they have the barcode 21 or the numbers 22 in the edge areas 7 emboss the data carrier.

There is the possibility of the embossing rollers 31 . 33 and / or the disk 1 or its edge surfaces 7 to heat and thus the transformation of the edge surfaces 7 to facilitate (hot stamping). However, it is also possible to use characters etc. in the edge surfaces 7 to emboss without the embossing rollers 31 . 33 and / or the disk 1 or its edge surfaces 7 to heat (cold stamping).

The embossing roller 35 for embossing letters and the embossing roll 37 for embossing another bar code are in 3 moved away from the transport device and thus do not touch the edge surfaces 7 of the card-shaped data carrier 1 when it passes them. In the position shown emboss the rollers 35 . 37 thus no symbols on the data carrier. The provision of multiple embossing rolls 31 . 33 . 35 . 37 , each on both an edge surface 7 of the disk 1 pressed as well as can be lifted from this, allows a variation of the security feature. Thus, the volumes may be provided with different security feature features associated with particular groups of customization / personalization features.
