Description

The present invention relates to a data carrier with the features of claim 1, a method for producing a data carrier with the features of claim 15 and a value or security document with a data carrier according to the invention with the features of claim 18.

It is known from practice to equip data carriers with security elements to identify persons or to prove authorization in order to protect the data carrier against forgery or copying. A distinction can be made between security elements that can be checked with the naked eye and security elements that require additional tools for checking.
Some of the security features are also personalized and thus assigned to the person to be identified by the data carrier. In particular, these personalized security features are often the subject of counterfeiting.
To protect value or security documents against counterfeiting, a wide variety of security features are therefore proposed in a known manner, including, for example, guilloches, watermarks, printed images, security features produced by laser marking, holograms, angle-dependent images or luminescent images.
Nevertheless, counterfeiters manage time and again to create a counterfeit copy of data carriers or to falsify individual security features on genuine data carriers.

The invention is therefore based on the object of specifying a data carrier of the type mentioned at the outset, which has improved protection against counterfeiting compared to previously known solutions, and of specifying a method for its production.

According to the teaching of the independent claims, this object is achieved by a data carrier according to claim 1 and a corresponding method for producing a data carrier according to claim 15. Various embodiments and advantageous developments of the invention are the subject matter of the dependent claims.

A first aspect of the invention accordingly relates to a data carrier with a base body, a first security element and a lacquer layer consisting of lacquer material arranged on a partial area of a first outer side of the base body, the first security element consisting of a first partial image and a second partial image arranged in the base body Partial image formed overall image shows, in which case in the base body by means of laser radiation from a variety of in each case at least partially perforation pattern formed over a total thickness of the base body extending through holes is introduced, wherein the lacquer layer with the first security element and at least a subset of the plurality of through holes seen from a direction of an observer forms an overlapping area.

With the invention it is achieved that in the event of an attempt to forge the first security element of the data carrier according to the invention, both a manipulation of the first partial image and a manipulation of the second partial image is required. In addition, the perforation pattern means that the data carrier can be checked from two different directions in a very simple manner without tools. If the first or second partial image is manipulated, the base body is to be separated into parts, with subsequent renewed assembly being prevented by the through-holes of the perforation pattern, without manipulation being evident.

The data carrier can be a card-shaped data carrier. The data carrier can have an ID1 format and can be an ID card, a credential or a bank card. For example, the data carrier can be an identity card, a driver's license, a membership card, a debit card or a credit card. The data carrier can comply with the ISO 7810 standard. The data carrier can also have an ID-3 format, i.e. be a data page, and be connected to other components of a value or security document, for example a passport, by means of a hinge element protruding from a side edge of the data carrier.

The base body of the data carrier can have a multi-layer structure and the individual layers can be connected to one another over a large area, in particular laminated, by the action of heat and under pressure. An exemplary structure of the base body can have a first layer structure made up of at least one first and one second layer and a second layer structure made up of at least one first and one second layer. A core layer having a filler can be arranged between the first layer structure and the second layer structure. Some or all of the layers of the first and second layer constructions can be transparent. The layers mentioned can be connected to one another, in particular laminated. The core layer can have one layer or be formed from several layers, preferably from two, three or four layers. A filler for the core layer or at least one of the core layers can be a metal oxide, titanium dioxide or a white pigment and the selected filler can be between 5 and 15% by weight of the layer containing the filler. In another embodiment it can be provided that the core layer consists of a Fiber material layer, for example made of paper or synthetic paper, is formed. In some embodiments, at least one layer of the core layer can be opaque.

An electronic assembly, which can be set up for data and/or energy transmission in an RFID or NFC system, can be embedded between the layers of the core layer made of plastic. For this purpose, the electronic assembly can have one or more of the following components: a chip module, a microprocessor, an electronic memory and an antenna. For example, communication with an external device is contactless at 13.56 MHz.

The number of layers of the first and of the second layer structure is not to be understood as being final. In another structure, the first and the second layer structure can also each comprise three, four or five layers. In one embodiment, the first layer structure can comprise a greater number of layers than the second layer structure.

At least one of the layers of the first and/or the second layer structure can have a laser-sensitive additive, such as carbon black. The layer of the first or second layer structure that is furthest away from the core layer can have a UV light-absorbing substance and/or a lower proportion of laser-sensitive additives than a remaining layer of the first or second layer structure. Such a UV light-absorbing substance is available, for example, under the name Chimassorb ^™ 81, Chimassorb ^™ 90 or Tinuvin ^™ from BASF.

The layers of the first and second layer structure as well as the layer(s) of the core layer can be made from a polymer material from the group consisting of polycarbonate (PC), polyethylene glycol terephthalate (PET), polyethylene glycol terephthalate glycol (PETG), polyethylene (PE), polyurethane (PU) or polyvinyl chloride (PVC).

Provision is preferably made for the first partial image and the second partial image to be spaced apart from one another in a direction perpendicular to the first outer side of the base body. In other words, the first partial image and the second partial image are in different planes.

The first partial image can be a printed image. The first partial image can be arranged on an inner layer of the first layer structure. In one embodiment, the first partial image can be arranged on the first outside of the base body and can correspond to a printed image extending in two main directions. The first partial image or the printed image can be made from a UV-curing ink material and applied using a printing device.

The first partial image and/or the second partial image can each represent individualized or personalized information, such as a person's facial image.

Furthermore, it can preferably be provided that the first partial image and the second partial image show the same individual or personalized information and differ only with regard to their respective color impression. In daylight, the first partial image can correspond to a colored printed image and can have different ink material for the colors cyan, magenta and yellow or different ink material for the colors red, green, blue. In one embodiment, the printed image can also have cyan, magenta, yellow and black ink material.

In an advantageous embodiment, the printed image is at least partially transparent to infrared light. It can thereby be achieved that the integrity of the second partial image can be checked when the first security element is irradiated with infrared light. Information in the second field that differs from the information in the first field would indicate a forgery.

An example of an ink material is in the reference EP 1 789 505 B1 or EP 1 789 506 B1 disclosed.

The second partial image can be a grayscale image generated by means of laser radiation. A pulsed Nd:YAG marking laser with a wavelength of 1064 nm can be used to generate the greyscale image. The first partial image and the second partial image can complement each other visually to form an overall image when the data carrier is viewed in a top view of the first outside. For this purpose, the first partial image and the second partial image are arranged and formed congruently with one another. In one embodiment, image parts of the first partial image can also be arranged in register with image parts of the second partial image.

To further increase protection against forgery, the printed image can be formed from at least one set of pixels with a first color impression, for example cyan, a second color impression, for example magenta, and a third color impression, for example yellow, with the pixels of an identical color impression along at least one main direction of the Print image can be arranged overlapping. Additionally or alternatively, the pixel density of the print image along a first main direction of the print image can differ from a pixel density along a second main direction of the print image.

The perforation pattern is formed from a multiplicity of through-holes, each of which extends at least partially over the entire thickness of the base body and which Lacquer layer can form an overlapping area with a subset of the plurality of through-holes of the perforation pattern when looking at the first outer side of the base body. In other words, the perforation pattern can at least partially overlap the lacquer layer.

Light can pass through the through holes. When viewing the data carrier in transmitted light, the perforation pattern is dominant. The effect is enhanced when the disk is viewed against a bright background. The perforation pattern is not visible or essentially not visible when the data carrier is viewed from above. The through-holes are preferably made in the base body perpendicular to the first outer side of the base body.

It goes without saying that the through holes of the perforation pattern can have different diameters. Also, the through-holes can have a circular or elliptical diameter. In partial areas of the perforation pattern, the through holes per cm ² can be arranged with different frequencies.

In one embodiment of the invention, the through-holes of the perforation pattern can extend completely over the entire thickness of the base body and can be introduced at an angle of between 25 and 70 degrees, in particular between 30 and 55 degrees, to the first outer side of the base body. The consequence of this is that the perforation pattern is not visible when the viewing angle is perpendicular to the first outer side of the base body and is only visible by tilting the base body.

The perforation pattern represents individual or personalized information. Such information can be a unique number or a facial image of a person. Alternatively, the information can also represent a non-individual symbol, for example a coat of arms. For example, the perforation pattern can represent the information of the first or second sub-image.

Each of the through holes extends at least over 50% of the total thickness of the base body. The through-holes preferably extend over 75% of the total thickness of the base body and very particularly preferably the through-holes extend completely over the total thickness of the base body. In the case of through holes extending completely over the entire thickness of the base body, each through hole of the perforation pattern has a through opening arranged both on the first outer side of the base body and on the second outer side of the base body. With increasing extension of the through hole over the Overall thickness of the body increases the visibility of the through hole as part of the perforation pattern in transmitted light.

For a functional perforation pattern, it is irrelevant whether the through-holes are introduced into the base body from the direction of the first outside or from the direction of the second outside. If the through-holes extend completely over the entire thickness of the base body or are introduced into the base body from the direction of the first outside, at least some through-openings of the subset of the plurality of through-holes can be closed by the lacquer material of the lacquer layer. In one embodiment, the through-openings of the subset of the multiplicity of through-holes can be closed by the lacquer material of the lacquer layer.

The through-holes of the perforation pattern can have a diameter of between 75 and 150 μm, in particular between 75 and 120 μm.

In another advantageous embodiment of the invention, it can be provided that the perforation pattern with through holes introduced completely over the entire thickness of the base body at least partially overlaps with the first security element. Consequently, some of the through holes of the perforation pattern intersect the first and second partial images. The through-holes intersecting the first partial image are preferably free of ink material, so that the passage of light through the through-holes is not impaired.

Another embodiment comprises a data carrier with a base body, a first security element and a lacquer layer consisting of lacquer material arranged on a partial area of a first outer side of the base body, wherein the lacquer layer forms an overlapping area with the first security element when viewed from one direction of an observer, wherein in the A perforation pattern formed from a plurality of through-holes extending at least partially over the entire thickness of the base body is introduced into the base body by means of laser radiation, and at least a subset of the plurality of through-holes of the perforation pattern are additionally introduced into the lacquer layer. In other words, a subset of the plurality of through-holes of the perforation pattern intersects the lacquer layer, the perforation pattern being introduced into the base body from the direction of the first outside.

A CO ₂ laser device with a wavelength of 1064 nm can be used to create the perforation pattern. Such a laser device is available, for example, from Rofin-Sinar Laser GmbH.

Furthermore, it can be provided that a second security element is arranged in the base body or on an outside of the base body and forms an overlapping area with the perforation pattern, the second security feature being visible when viewing the first or the second outside of the base body. Thus, in one embodiment, some of the through holes of the perforation pattern may intersect the second security feature.

The second security feature can be visible when viewing the first outside and not visible when viewing the second outside. In particular, the second security element can be arranged on an inner layer of the first layer structure or on a side of the core layer facing the first layer structure.

In another embodiment, the second security feature may not be visible when viewing the first outside and visible when viewing the second outside. In particular, the second security element can be arranged on an inner layer of the second layer structure or on a side of the core layer facing the second layer structure. This has the effect that a security feature assigned to the second outside of the base body is reinforced in terms of its security against forgery.

The second security feature can be, for example, a watermark, a hologram, a laser image, a printed image, a negative image, a reverse image, a guilloche pattern, a metallic layer or a printed image that only shows a color impression when excited with UV light. The second security feature can represent individual or personalized information as a printed image or as a laser image. Personalized information can be, for example, a facial image of a person or of an owner of the data carrier. Individualized information can be, for example, a unique sequence of digits or a unique alphanumeric character. As a facial image, the second security feature can be identical to the information represented by the first and/or second partial image.

The data carrier can also have other security features beyond the first and second security feature. For example, a third security feature can be exclusively machine-readable and contain the information represented by the perforation pattern in machine-readable form.

Provision is preferably also made for the lacquer layer to be arranged only on a partial area of the first outer side of the multi-layer base body. The partial area thus has a smaller area than the first outside of the base body and an area covered by the lacquer layer can preferably be between 15 and 40% of the area be the first outside of the body. The first partial image preferably has a smaller surface area than the partial area.

The lacquer layer can form an overlapping area with the first security element when looking at the first outside of the base body. In other words, the lacquer layer at least partially covers the first security element, with the lacquer layer covering the first partial image in a touching manner. In one embodiment, the lacquer layer can also cover the entire surface of the first partial image.

In one embodiment of the invention, the lacquer layer can have an uneven surface structure on its side facing away from the base body. This can be achieved, for example, by varying the application height of the lacquer layer or by contacting it with an embossing stamp. In this way, further effects that increase the security against forgery can be imparted to the lacquer layer.

In a further embodiment of the invention, the lacquer layer can have interruptions, the first outer side of the base body being free of lacquer material in the area of the interruptions. In particular, the lacquer layer can have interruptions in the overlapping area with the first security element. Consequently, the paint layer can be formed from a plurality of paint elements with the same or different contours. The lacquer elements can be spaced apart from one another by the interruptions. The lacquer elements can have a variable application height, which intensifies a haptic impression.

The lacquer layer can consist of a UV-curing lacquer material. In particular, the lacquer material can consist of a polymer material containing photoinitiators and based on acrylate monomers or acrylate oligomers, and can be cured by a polymerisation reaction. Leveling agents, defoamers or curing accelerators can be contained in the coating material as auxiliaries.

Another example of a paint material may be a polyester paint resin, polyethylene terephthalate paint resin, a (meth)acrylate paint resin, or a mixture of (meth)acrylate paint resins. In one embodiment, a coating resin based on urethane acrylates can be provided for the coating material. Comparable lacquer material is available from Proell GmbH, Germany.

Furthermore, starting from the first outer surface of the base body, the lacquer layer can have an application height of 2-12 μm, preferably 4-8 μm. Light with a wavelength of 200-400nm is particularly suitable for curing.

The lacquer material can preferably be transparent or translucent in the visible spectral range. Optionally, the lacquer material can have an optical feature substance which shows an optical effect that is visible in daylight or which can only be checked when excited with ultraviolet light. This has the advantage that the presence or the integrity of the paint material can also only be checked with a technical aid. The feature substance that is visible in daylight can be checked with a microscopic device and can comprise, for example, metallic effect pigments of a mineral or metallic type. The feature substance that can be checked when excited with ultraviolet light can comprise a luminescent substance or a fluorescent substance. The amount of luminescent or fluorescent substance can preferably be less than 5% by weight of the lacquer material, particularly preferably less than 2% by weight.

In a further advantageous embodiment, it can be provided in connection with the second security feature that the second security feature shows a first color impression only when excited with UV light of a first wavelength, wherein the optical feature substance can be selected in such a way that the optical feature substance when excited with UV light of the first wavelength shows no recognizable color impression and, when excited with UV light of a second wavelength that differs from the first, shows a first color impression or a second color impression that differs from the first. In other words, the optical feature substance can only show a first or second color impression when excited with UV light of a second wavelength and the second security feature can only show a first color impression when excited with UV light of a first wavelength. The first wavelength can preferably be in a range from 300 nm to 400 nm, particularly preferably in a range from 310 nm to 370 nm. The second wavelength can preferably be in a range of less than 300 nm, particularly preferably in a range from 230 nm to 270 nm.

In step d1), the paint layer can preferably also only be applied to a partial area of the first outer side of the multi-layer base body. In step c2), the perforation pattern can be generated in one embodiment in such a way that the perforation pattern at least partially overlaps the printed image.

The production includes in particular a personalization of the data carrier. The printed image and the grayscale image may each represent individualized or personalized information, such as a person's facial image. In particular, the printed image and the grayscale image can be generated in a congruent arrangement with respect to one another, that is to say they can be identical in terms of their dimensions.

In step c2), according to one embodiment, it can preferably be provided that the through holes are made in the base body, extending completely over the entire thickness of the base body, or are made in the base body from the direction of the first outer side, it being possible in step d1) to provide that Lacquer material is applied in such a way that at least some through-openings, arranged on the first outer side of the base body, of the subset of the plurality of through-holes are closed by the lacquer material of the lacquer layer.

Furthermore, it can be provided in step d1) that the lacquer layer is applied to cover the entire surface of the printed image and/or that the lacquer layer is applied with an uneven surface structure.

To produce the data carrier, a device can be used which has a printing device, in particular a drop-on-demand inkjet printer, a first curing module, at least one laser device, one for applying paint equipped printing device and a second curing module comprises. To produce the first security feature, the perforation pattern and to apply the layer of lacquer, the data carrier can be transported to the individual modules and the at least one laser device of the device.

A further embodiment of the method provides that the data carrier is moved along a conveying direction during the generation of the printed image and, in order to generate the printed image, at least one set of pixels with a first color impression, a second color impression and a third color impression is printed on the first outer side in such a way that that the number of pixels of an identical color impression overlap along at least one main direction of the printed image or, to generate the printed image, pixels are applied to the base body along a first main direction of the printed image with a different pixel density along a second main direction of the printed image. In this way, an improved image quality can be achieved in a particularly advantageous manner.

The first curing module can be used for irradiating the printed image with UV light using a first curing profile, and the first or the second curing module can be used for irradiating the lacquer layer with UV light. The curing modules can each comprise a lamp, for example one or more controllable light sources. The first curing profile can be different from the second curing profile and can differ in particular with regard to the light intensity and/or the duration of the irradiation.

An embodiment of a data carrier 10 according to the invention is in Figure 1a shown. The data carrier 10 has a base body 12 with an in Figure 1a first outer side 14 visible in plan view, ie a front side, and a second outer side 16 opposite the first outer side 14, ie a rear side. An overall thickness of the base body 12 is defined between the first outer side 14 and the second outer side 16 of the base body 12 . A total thickness of the base body 12 can be 0.7 mm to 0.9 mm. The base body 12 is formed from a plurality of layers which are connected to one another, preferably by hot or cold lamination. Using the example of Figure 1b , showing a section along the line II-II of Figure 1a shows, the base body 12 is formed from a first layer structure 12a, a second layer structure 12b and a core layer 12c arranged between the first layer structure 12a and the second layer structure 12b.

The data carrier 10 has a first security feature 18 . The first security feature 18 shows the viewer, when looking at the first outside 14, an overall image which is formed from a first partial image 18a and a second partial image 18b is. The two partial images 18a, 18b of the present invention can complement each other in terms of their respective color spectrum. The first partial image 18a can be arranged on the first outside 14 of the base body 12 or on an inner layer of the base body 12, in particular a surface of an inner layer of the first layer structure. The first partial image 18a can preferably be a printed image which extends in at least two main directions. The second partial image 18b is arranged on or in an inner layer of the base body 12, the second partial image 18b being further spaced from the first outer side 14 of the base body 12 than the first partial image 18a.

A perforation pattern 20 is introduced into the base body 12 by means of laser radiation. The perforation pattern 20 is formed from a multiplicity of through holes 22 which each extend at least partially over the entire thickness of the base body 12 . In the Figure 2b as well as in the following cross-sectional illustrations, the through holes 22 extend completely over the entire thickness of the base body 12. For a better understanding of the invention, the perforation pattern 20 is shown in plan view in the figures of the present invention. In fact, the perforation pattern 20 is not visible or only weakly visible in plan view and must be viewed in transparency or transmitted light in order to be able to check it.

In particular from Figure 1b It can be seen that each of the through-holes 22 has a corresponding through-opening 24 on the first outer side 14 of the base body 12 and, if the through-holes 22 extend completely over the entire thickness of the base body 12, a corresponding through-opening 26 on the second outer side 16 of the base body 12. Deviating from the representation in Figure 1b it is possible that some or all of the through holes 22 extend only partially over the entire thickness of the base body 12 and are introduced into the base body 12 from the direction of the first outer side 14 or are introduced into the base body 12 from the direction of the second outer side 16. For illustration are in the figures 1b , 2 B and 3b seven through-holes 22 of the perforation pattern 20 are shown, the number and/or the shape of the through-holes 22 not being limiting, but to be understood purely as an example. The number and/or the shape of the through-holes 22 can also differ from the representation in FIGS figures 1b , 2 B and 3b vary.

Furthermore clarified Figure 1b that the first partial image 18a and the second partial image 18b are arranged congruently to one another and are arranged in different planes. For example, the partial image 18a and the partial image 18b each show a face image of a person.

A lacquer layer 30 consisting of lacquer material is arranged on a partial region 28 of the first outer side 14 of the base body 12 . The partial region 28 can have a smaller surface area than the first outer side 14 of the base body 12. The lacquer layer 30 can have a smaller surface area than the first outer side 14 of the base body 12. The lacquer layer 30 forms with the first security element 18 and at least a subset of the plurality an overlapping area at through holes 22 when looking at the first outer side 14 of the base body 12 . Subsequent manipulation of both the first partial image 18a and the perforation pattern 20 is thus made more difficult. Using the example of Figures 1a and 1b the lacquer layer 30 completely covers the first partial image 18a on its side facing away from the base body 12 . In addition, the lacquer layer 30 has a larger surface area than the first partial image 18a. However, it is also possible for the lacquer layer 30 to only partially cover the first partial image 18a.

As in Figure 1b shown, the lacquer layer 30 can be arranged with a constant application height on the first partial image 18a or on the first outer side 14 and the first partial image 18a. In a different embodiment, however, it can be provided that the lacquer layer 30 is arranged with a different application height in sections on the first partial image 18a or on the first outer side 14 and the first partial image 18a. In other words, the application level can vary between a maximum application level, for example 12 μm, and a minimum application level, for example 2 μm, without exceeding the maximum application level and falling below the minimum application level. This enables surface structures to be formed, for example in the form of information or optical effects.

The data carrier 10 also has a second security feature 34 which can be arranged in the base body 12 or on an outside of the base body 12 . The second security feature 34 is arranged in an overlapping manner with the perforation pattern 20 and/or with markings 36 arranged in the base body 12 . The second security feature 34 is visible when looking at the first outside 14 and is not visible when looking at the second outside 16 . The identifiers 36, such as individual or personal data, can be introduced into the first layer structure 12a of the base body 12 by means of a laser beam.

the Figures 2a and 2b show a second embodiment of a data carrier 10 according to the invention Figures 2a and 2b Disk 10 shown can in connection with the Figures 1a and 1b have the characteristics described. However, the data carrier 10 differs from the data carrier Figure 1a and 1b in that the lacquer layer 30 arranged on the partial area 28 has interruptions 32 . in the In the area of the interruptions 32, the first outside 14 of the base body 12 and/or the first partial image 18a are free of paint material. The lacquer layer 30 can consequently be formed from a plurality of lacquer elements spaced apart from one another. For illustration are in the Figure 2a Nine paint elements shown, the number and / or the shape of the paint elements is not limiting, but is to be understood purely as an example. The number and/or the shape of the lacquer elements can also differ from the illustration in Figure 2a vary. Some lacquer elements of the lacquer layer 30 can only cover the first partial image 18a and some lacquer elements of the lacquer layer 30 can exclusively cover one or more through-openings 24 of the perforation pattern 20 .

In addition or as an alternative to the interruptions 32, the lacquer layer 30 can have an uneven surface structure on its side facing away from the base body 12. This further increases the security against counterfeiting.

Like noting the Figures 1a and 1b mentioned above, the lacquer layer 30 can also completely cover the first partial image 18a on its side facing away from the base body 12 .

the Figures 3a and 3b show a third embodiment of a data carrier 10 according to the invention Figures 3a and 3b Disk 10 shown can in connection with the Figures 1a to 2b have the characteristics described. However, the data carrier 10 differs from the data carrier from the Figures 1a to 2b in that the perforation pattern 20 additionally overlaps the first security element 18 at least partially. the Figure 3b 12 shows that the through holes 22 of the perforation pattern 20 overlapping with the first security element 18 intersect the first partial image 18a and the second partial image 18b.

By preferably producing the perforation pattern 20 after the first security feature 18 has been produced, the through holes 22 overlapping the first security feature 18 are free of ink material and the complete appearance of the perforation pattern 20 is not impaired. In contrast, the application of the lacquer layer 30 introduces lacquer material at least partially into the through-holes 22 overlapping the first security feature 18 if the through-holes 22 overlapping the first security feature 18 are introduced into the base body 12 from the direction of the first outer side 14.

Like noting the Figures 2a and 2b mentioned above, the lacquer layer 30 arranged on the partial area 28 can, however, also have interruptions 32 . In the field of Interruptions 32 are the first outside 14 of the base body 12 and/or the first partial image 18a free of lacquer material.

the figure 4 shows a rear side or a top view of the second outer side 16 of a data carrier 10 according to the invention according to a further embodiment. The data carrier 10 shown has a second security feature 35 which can be arranged in the base body 12 or on the second outer side 16 of the base body 12 . The second security feature 35 is arranged so that it overlaps the perforation pattern 20 . In addition, the second security feature 35 is not visible when the first outside 14 is viewed and is visible when the second outside 16 is viewed.

In the figure 5 a schematic side view of a value or security document 100 with a data carrier 10 according to the invention is shown. The value or security document 100 is shown in the half-opened state. The valuable or security document 100 is a passport, for example. The valuable or security document 100 comprises a cover 102 with a first cover half 102a and a second cover half 102b connected to the first cover half 102 in a fold area F. In the closed state, the two cover halves 102a, 102 are essentially congruent with one another. The cover 102 can be made of multiple layers. In addition, an electronic assembly for contactless communication with an external device can be accommodated in the first or second cover half 102a, 102b. At least the data carrier 10 and several document pages 104 are connected to one another via a seam (not shown). The seam runs along a flexible hinge element 106 connected to the data carrier 10 and protruding laterally opposite a side edge of the data carrier 10. The data carrier 10 and the document pages 104 together form an inner part which can be adhesively attached to the cover 102 in the fold area F. Alternatively, the cover 102, the data carrier and the document pages 104 can also be connected to one another via the seam. When the valuable or security document 100 is in the open state, the data carrier 10 and each document page 104 can be turned over or folded over.

In the open state of the value or security document 100, a document side 104 is also arranged opposite the data carrier 10 with respect to the seam. The document page 104 opposite the data page 10 can have a perforation pattern 120 . The perforation pattern 120 can represent information arranged in or on the data carrier 10 . For example, the perforation pattern 120 can be customized or personalized. The data page 10 is integrated into the value or security document 100 in such a way that an observer sees the first outer side 14 of the data carrier 10 with the document side 104 can compare without turning the data page 10 is required. This enables an optical comparison of the data carrier 10 and the document page 104 that can be carried out in a simple manner.
