EP3291996B1 - Data carrier for inserting into a notebook- or book-shaped object and method for producing the same - Google Patents

Description

The present invention relates to a data carrier for insertion into a book or book-shaped object, and to a method for producing a data carrier. Such data carriers are known in the security document field and are typically used as part of passports or other book or book-shaped security documents.

In the area of passport books, the trend in recent years has been that important personal data of the bearer of the passport is on a data page, such as a plastic card, which is inserted into the otherwise made of paper passport book. So that the rigid plastic card can be turned over like a normal paper page in the passport book, it requires a hinge or a link that connects the plastic card with the passport book. For this purpose, there are various solutions that are based, for example, to provide a passport card on the inside of the passport with a textile or flexible strip, by means of which the card can be sewn into the passport book.

Various solutions are known from the prior art for this purpose:
Out DE 10 2012 019 308 A1 An inlay for a data page for a passport is shown. The inlay has a fabric layer intimately bonded to a plastic layer which fills the meshes of the fabric so that the inlay has a closed profiled surface. This surface is formed on the one hand by the raised tissue structure of the tissue layer and on the other by intermediate intermediate surfaces of plastic material. The surface dimensions of the inlay correspond to the outer dimensions specified for a data page plus a fastening area with which the data page can be fixed in the passport book and which for this protrudes beyond the main part of the data page. In one embodiment, the inlay may also form a stripe in the data page that survives at an edge of the data page.

In DE 10 2010 053 640 A1 a multilayer data carrier is proposed which has at least one integrally coextruded strip film and at least one further film associated therewith. The coextruded strip film has a strip of soft material and a strip of stiff material. The further film is formed by a stack of layers which covers only a part of the strip film and a marginal zone over the strip made of soft material uncovered. The layer stack area forms the data area of a data page. The soft tab area serves to sew the data carrier into a passport book.

From the EP 2 479 038 A1 the preamble of claim 1 or a security document is known, in which a tab is connected to a data page via a formed by laser welding thermal connection.

From the US 2014/0265301 A1 is the preamble of claim 1 or a product with a flexible joint and a data page known. A first optical feature is formed in the flexible joint and a second optical feature is formed in the data side, wherein the first optical feature and the second optical feature are intended to produce a common optical effect. From the DE 10 2005 034 134 A1 there is known a book-type document, in particular an identification document, with a book cover or a book cover comprising at least one personalization data page and a plurality of inner pages sewn with a header and connected to the book cover or book cover, the personalization data page having a seam-facing tab, wherein at least one security feature or at least a part of the at least one security feature of the personalization data page, the inside, the book cover or the book cover is incorporated in the tab.

Furthermore, it turns out DE 10 2012 213 913 A1 a passbook card which has a connection tab for connecting a book or stapling page with a passport document. The connecting strap is formed of a textile material. For this purpose, the connecting tab with the booklet or book page are arranged overlapping and both welded together in the overlap region, in particular by means of ultrasound. It is stated that a printed image in the form of alphanumeric characters present in the booklet or book page is made visible by the welding through the connecting tab.

A key objective of all ID documents is the protection against counterfeiting. To this end, the highest possible barriers to counterfeiting and falsification of the documents are set up.

In the many types of falsification and falsification of passbooks, the complete exchange of data pages in the passbooks is a commonly used forgery method For this purpose, the data page is separated from the tab and replaced by another, possibly manipulated, data page.

Therefore, a problem underlying the present invention is that conventional passport booklet constructions are not sufficiently secure against the data page exchange, and in particular that it is difficult to visualize manipulation.

It is thus desirable to provide a data carrier for insertion into a book or book-shaped article, in particular a passport book, and a corresponding method in which the security against counterfeiting is increased.

The invention is therefore based on the problem to provide a data carrier and a manufacturing method, which ensure increased security against counterfeiting of the data page.

The technical problem is solved by a data carrier with the features of claim 1 and a method having the features of claim 14. Advantageous embodiments of the invention will become apparent from the dependent claims.

The invention is based on the idea to provide a data carrier in which a data page via a textile or flexible connecting element, such as a textile or flexible tab, in a book or book-shaped object, in particular a passport book is inserted. In this case, an overlap region between the data page and the connecting element can be processed with a laser and laser-engraved according to the invention, so that this overlapping region can be provided with at least one security feature. In this case, the information components of the security feature are located both partially on and / or in the data page as well as partially on and / or in the connection element. When exchanging the data page, the security feature whose detectable information components are partly stored in the data page and partly in the connection element is destroyed and thus a forgery is visible. A fake of the disk is made difficult or even impossible. Furthermore, it is provided that the security feature extends beyond the overlapping area and is introduced integrally in a transition region between the data page and the connecting element by means of the laser processing, wherein the security feature is partially formed in the overlapping area and partially outside the overlapping area

definitions

A data carrier is a physically trained carrier of information, in particular of personalized data for identification purposes, in particular for passports or other book or stapled objects. The data carrier may include both optically detectable by humans characteristics, in particular security features, as well as machine-readable features, in particular security features. The data carrier comprises at least one data page.

The book or book-shaped object with the data carrier inserted therein according to the invention is in particular a passport book. Alternatively, it can also be another security document into which a data page is inserted. This article preferably has a stiff and sturdy booklet or cover on the outsides from two parts on, a front part and a back part, which are connected by a book or book spine. Furthermore, in addition to the data page, the article may also have booklets or book pages, which are typically made of paper and serve to receive subsequently inserted information, in the case of a passport (passport) of registered visas, etc.

For the purposes of the present invention, a data page means a flat, preferably rectangular, carrier, for example for information to be displayed about an entity, such as a person or a thing, the information being either in plain text or in coded form, either in the Eye recognizable form or only in recognizable with an optical aid form or in electronically stored form, for example in an electronic semiconductor chip to which an external electrical contact and / or contactless by means of an associated antenna (RFID) can be communicated. The data page, preferably a data card, is inserted via the connecting element in the book or book-shaped object, for example by sewing. The data page comprises individualizing data of the person or thing to which the security document is associated, in plain text or in encrypted or suitably designed form, which is hardly or hardly imitable, such as data reproduced with specific luminescent colors in, for example, alphanumeric Presentation. The data page may further include common security features, such as electromagnetic radiation diffractive elements, such as volume or surface holograms, tilts, special print patterns, such as guilloches (especially in pastel colors), and variable colors, surface embossing, and the like. Further, the data page may also include electronic components such as electronic displays, sensors such as touch sensors, and the like.

The format of the data page depends on the book or book-shaped object in which the data page is to be inserted. For example, it may have one of the formats ID 1, ID 2 or ID 3 according to ISO / IEC 7810. In general, the data page is a plastic body which is formed, for example, by a laminate of a plurality of laminate layers, which are bonded to one another in a dimensionally accurate manner under the influence of heat and under increased pressure. For example, the laminate layers are made of a material suitable for lamination. The data page may be formed from a polymer selected from a group comprising polycarbonate (PC), in particular bisphenol A polycarbonate or a polycarbonate formed with a geminally disubstituted bis (hydroxyphenyl) cycloalkane, polyethylene terephthalate (PET), the Derivatives such as glycol-modified PET (PETG), polyethylene naphthalate (PEN), polyvinyl chloride (PVC), polyvinyl butyral (PVB), polymethyl methacrylate (PMMA), polyimide (PI), polyvinyl alcohol (PVA), polystyrene (PS), polyvinylphenol (PVP), polypropylene (PP), polyethylene (PE), thermoplastic elastomers (TPE), in particular thermoplastic polyurethane (TPU), acrylonitrile-butadiene-styrene copolymer (ABS) and their derivatives, polyamide (PA) and / or paper (cellulose) and / or Cardboard and / or a glass and / or metal and / or a ceramic. In addition, the data page can also be made from several of these materials be, especially if it is formed of several layers and the individual layers are made of different materials. Preferably, it consists of PC or PC / TPU / PC. The polymers may be either filled or unfilled. In the latter case they are preferably transparent or translucent. If the polymers are filled, they are opaque. The filler may therefore be, for example, a pigment. The layers can be colored or colorless. The outer layers of the data page can be particularly colorless transparent and have a high abrasion resistance. The above information relates both to films to be joined together and to liquid formulations applied to a precursor, such as a protective or topcoat. A laminate formed in this way can finally be coated on one or both sides with the protective or topcoat or with a film. In particular, the film may be a scratch-resistant film. Overlay layers formed in this way protect a security feature arranged underneath and / or give the document the required abrasion resistance. In principle, the data card can also be produced by (co) extrusion. The thickness of the data card is preferably 250 to 950 μm.

The connecting element, in particular a connecting lug, is preferably an elongate, in particular rectangular, sheet which is sufficiently wide in order to be able to be overlapped with the data side at the edge, so that a firm joining connection can be produced in this area, and around others to be able to form an area for incorporation in the book or book-shaped object. Preferably, the connecting element is as long in an extension direction as the data side, so that the connecting element extends over an entire edge length of the data page and not beyond. In the volume, the connector overlaps the data page in the overlap area so that another connector area of the connector projects laterally beyond the data page. This connection area is used for subsequent connection of the data carrier with the body of the book or book-shaped object. The connecting element can have at least one security feature, for example one or more security threads or additional printing.

Preferred embodiments

In particular, thus a data carrier is provided, suitable for insertion into a book or book-shaped object, wherein the data carrier comprises a data page and a connecting element and the data page and the connecting element are interconnected in an overlap region, wherein in the overlapping region Security feature is formed by laser processing and the information components of the security feature are partially formed in the data page and partially in the connecting element.

Furthermore, a method is advantageously provided for producing a data carrier suitable for insertion into a book or book-shaped object, comprising the following method steps: providing a data page and a connection element, arranging the data page and the connection element such that the data page and overlap the connector in an overlap area; and integrally bonding the data page to the connector in the overlap area so that the connector contacts and / or penetrates the data page in whole or in part; Forming a security feature by means of laser processing, wherein the information components of the security feature are formed in at least a region of the overlapping region both in the data side and in the connecting element.

In order to further increase the security against separation and replacement of a data page of the data carrier, security features extending beyond the overlapping area can be applied, which lie partly within the overlapping area as well as partly outside thereof. Therefore, the invention provides that a transition region between the data side and the connecting element is provided with a coherent laser-introduced security feature, wherein the security feature is partially formed in the overlapping region and partially outside the overlapping region in a boundary region of the data side. In this context, coherent means that the security feature extends, at least in part, in its graphic representation continuously, that is to say continuously, over a boundary line which marks the boundary between the overlapping area and the border area. In particular, a contiguous security feature includes lines that extend across the boundary line, for example, in alphanumeric characters that are formed partly in the overlap area and partly in the border area. The security feature may include, for example, personalized data such as a number, an alphanumeric string, a code, a seal, an image or other symbols, or machine-readable characters. If the data page is separated out, the described transition area is destroyed and a later-inserted, possibly changed data page would have to have exactly the same character string at exactly the same locations or interfaces as the original data page in order to be genuine to be recognized. A counterfeiting of the data carrier is made considerably more difficult or even impossible.

The advantage of the invention is that the laser processing carried out after connecting the data side to the connecting element is carried out both in the data side and in the connecting element, thereby forming a common security feature. This security feature, for example personalized information in the form of a number or an alphanumeric code, is then partly formed both in the data page and in the connection element, so that the overall visual impression of the security feature originates both from the data side and from the connection element. Disconnecting the data page from the connector would remove one of these pieces of information from the security feature, destroying the overall look. In a subsequent exchange of the data page, the exact replica of the missing information component to obtain the original overall impression is almost impossible, so that the data carrier with the exchanged data page is easily recognizable as a forgery. The proposed data carrier and the associated method thus lead to an increased security against forgery of security documents.

The invention provides that the data page comprises a laser doping. The laser doping ensures that an introduced laser power is absorbed mainly in the laser-doped area and leads there to a material blackening. As a result, it is possible to selectively edit a specific area in the data page. In addition, a much lower laser power
necessary to achieve a desired blackening of the data page material. If an absorption of the laser power in the area of the laser doping and a blackening is set in motion, in some cases adjacent areas are also heated to a greater extent and thus blackened.

In order to achieve targeted absorption of laser power in the connecting element, laser doping in the connecting element may also be desirable here. In a further embodiment of the data carrier is therefore provided that the connecting element comprises a laser doping.

In order to make the connecting element flexible and loadable, it is necessary to use a flexible and yet reliable material for heavy use. Therefore, an embodiment of the invention provides for the use of a textile material for the connecting element.

The textile material of the connecting element may be formed by filaments, in particular yarn, threads or fibers. It may in particular be formed by a textile fabric in the form of a woven, knitted fabric, knitted fabric, braid, stitchbonded fabric, a nonwoven fabric, felt or a felt-like fabric or even another textile material. In the case of a woven, knitted, knitted, braided or knitted fabric, the threads, fibers or yarn from which it is formed are regularly arranged. In the case of a nonwoven fabric, felt or felt-like fabric, the arrangement is irregular. Preferably, the textile material is formed by a fabric with warp and weft threads. Preferably, it is a tissue. In particular, the fabric may have a mesh size of at least 30 mesh, more preferably at least 60 mesh. The mesh size is at most 300 mesh.

The textile material of the connecting element may consist of or contain one or more fusible materials, for example to enable a welding process. However, this is not absolutely necessary, since a connection can also be made in other ways, in the case of a welding process in that the data page has a fusible material. The textile material is preferably made of plastic (polymer). It has been found to be particularly advantageous to use as plastic a polyester, for example polyethylene terephthalate (PET), polyamide (PA), or a thermoplastic polyurethane (TPU), because these materials can easily spin or extrude into yarns or the like, and then to process the textile material further. The textile material may preferably at least partially formed from polyester. Alternatively, other materials are conceivable, such as cotton or metal. The melting point or the softening temperature (Vicat softening temperature according to DIN EN ISO 306) of a fusible material is preferably to be adapted to the material properties of the data side. The melting or softening temperature of the textile material is preferably higher than the melting point or the softening temperature of at least one material on the data side. In particular, it is important that the textile material of the connecting element maintains its shape during joining, while at least one material of a layer region of the data side melts during joining, so that the connecting element can penetrate into this layer material. The layer area refers to that part of a data page that is made up of several joined layers. In the case of a connecting member to be joined by welding or laminating to the data side, the melting point of the textile material of the connecting member is higher than the laminating or welding temperature. Optionally, the textile material does not have a melting point or softening temperature, but decomposes at elevated temperature (for example in the case of a thermosetting polymer or a non-fusible natural product such as cotton or cellulose) and therefore retains its integrity.

The textile material may be formed from one or at least two materials (for example, a blended fabric). In the case of a textile material consisting of two materials, a first and a second material, the materials may be selected such that the first material melts or melts under the joining conditions and does not melt or melt the second material. For example, it may be provided that the second material is not a fusible material (in particular no thermoplastic material), for example a material other than a plastic. The other material may be a cellulosic material or a protein, for example a wool material, or a thermosetting plastic and / or carbon, fiberglass, inorganic fibers or metallic fibers (wires). For example, the textile material may be formed by a fusible plastic as a first material and cotton as a second material, for example by a cotton-polymer blend, in particular a cotton-polyester blend. For example, the warp threads of a blend fabric can remain unchanged during welding and press into the data page, while the weft threads on or melt and firmly connect with the material on the data side. The weft threads extend in this case from the free edge of the connecting element in the overlapping region, while the warp threads are parallel to the edge of the data side on which the connecting element is mounted.

The textile material and optionally a material layer of the connecting element are designed so that a printing under the connecting element remains clearly visible after the joining process. For this purpose, the textile material and optionally the material layer are transparent or at least translucent at least after the joining process. When using non-dyed textile materials, it has been found that the underlying printing is also visible through them because the optical scattering effects as a result of their embedding in the plastic on the data side as a whole are significantly reduced.

For the connection of the connecting element with the data page, the textile material should be such that it penetrates as far as possible in the joining process in the material of the data page. For this purpose, it may in particular be particularly open-pored. The material of the data side melts on and penetrates into these pores or spaces of the textile material of the connecting element.

In a further embodiment, a portion of the fibers of the textile material is provided with a laser doping. As a result, the absorption of the laser power during laser processing can be specifically increased and / or adjusted.

In one embodiment of the invention, the fibers of the textile material comprise laser-doped polycarbonate fibers.

For the design of the printed image in the laser processing and to increase the security against forgery of the security feature, it may be desirable to define the depth of the laser processing in the overlap area exactly. For this purpose, it is provided in a further embodiment of the invention that the textile material is transparent and / or open-mesh and thereby at least one underlying laser-doped film on the data side through the connecting element can be described by means of laser processing. Since both the data page and the connecting element are described by means of laser processing, a sharp and uniform print image, which makes a subsequent exchange of the data page, for example by a separation and replacement, makes visible, since the print image can not be restored to its original quality.

Another way to create a flexible but stable and durable even in heavy use connection, provide slides. A further embodiment of the invention therefore provides that the connecting element is a flexible, transparent as well as translucent, laser doped film comprises. For example, films made of PET, PC, ABS, PVC, polyamides, polyolefins, styrene polymers or the like can be used here. Also films based on elastomers can be used advantageously as a hinge material because of their flexibility. Likewise, textile surfaces can be used which are laser engravable. In addition to transparent and translucent films and transparent and translucent textile surfaces, opaque laser-markable films or opaque laser-markable textile surfaces can also be used.

In another embodiment, it is provided to connect the connecting element by means of a laser-doped adhesive to the data side. In this way, the layer of the adhesive can be provided with a print by laser processing. This increases the quality of the printed image and the security against counterfeiting or imitation is increased due to higher demands on the security feature in the overlap area. As adhesives, for example, physically setting adhesives, all types of reactive adhesives, as well as thermoplastic can be used.

When using materials that were originally not laser-doped for the connecting element, it may be advantageous to increase the absorption of the laser radiation used for processing to provide these materials with a doping prior to bonding. For this purpose, additional substances must be introduced. A further embodiment therefore provides that the connecting element is impregnated or filled or laminated with laser-doped materials. This increases the choice of materials that can be used as part of the fastener. The applied and / or introduced laser-doped materials may be, for example, doped adhesives, thermoplastics, elastomers or thermoplastic elastomers.

The Figures 1a, 1b and 1c schematically show the prior art for connecting a data page with a connecting element, which may be in particular a flexible connecting strap. In this case, all common joining techniques can be used, for example gluing, welding, riveting, etc. This always results in an externally visible overlapping area.

Fig. 1a shows a data carrier 1, which comprises a data page 2 and a connecting element 3, which overlap in an overlapping area 4. The data page 2 and the connecting element 3 are materially interconnected, for example in the method of ultrasonic welding.

Fig. 1b shows a data carrier 1, in which in the region of the overlap region 4, a cutout 11 is formed, in which the connecting element 3 is lowered, so that the finished connected data carrier 1 in the overlapping region 4 has a flush surface 12. The connecting element 3 is then firmly bonded to the data side 2, for example by lamination.

In Fig. 1c a variant is shown in which on the narrow side of the data page 2, a groove 13 is milled, in which the connecting element 3 is inserted. After pasting the data page 2 is connected to the connecting element 3 to a tongue and groove connection 4 '.

In the following, only one of the above-described connection variants will be shown by way of example for explaining the invention. The invention can be realized by the skilled person but also in the other connection variants.

In Fig. 2 Fig. 1 schematically shows an embodiment which facilitates the understanding of the invention. Shown is a data carrier 1, which comprises a data page 2 and a textile connecting element 6, for example made of thermoplastic material. The data page 2 comprises two films with laser doping 5. In an overlap region 4, the data page 2 and the textile connecting element 6 overlap. In the overlapping region 4, the textile connecting element 6 is connected to the two films with laser doping 5. In this case, the thermoplastic of the textile connecting element 6 has penetrated into the two films with laser doping 5, for example after applying pressure and temperature in a pressing operation. If the textile connecting element 6 is wide-meshed enough, then the material of the two films with laser doping 5 can completely surround the tissue or penetrate into the tissue, so that in the overlapping region 4 a cohesive connection and thus an area homogeneous area arises, in which there is a laser doping is. A security feature 14 can now be formed in this area by means of laser processing, in which certain areas in the overlapping area 4 are blackened by laser irradiation. In this case, both the data page 2 and the connecting element 3 are described, so that the information components 15 of the security feature 14 are formed both partially in the two films with laser doping 5 as well as partially in the textile connecting element 6. As a result, increased security against counterfeiting of the data carrier 1 or the data page 2 is achieved. For the at least partial marking of the tissue of the connecting element 3, it is not absolutely necessary for the material of the tissue to be laser-doped. If laser-doped material borders the tissue, blackening occurs via an energy input that begins initally at the boundary layer between the tissue and the laser-doped material.

The FIGS. 3 to 6 schematically show a section of the overlap region of a data carrier 1, both as a top view and as an elevation along a cross section 16. The data carrier 1 comprises a data page 2, consisting of a laser-doped film 5 and another layer 17, and a textile connecting element 6. Die Data page 2 and the textile connecting element 6 are in Overlap area bonded together materially. In the figures, the data page 2 and the textile connecting element 6 are shown separately for better illustration in the explanation of the invention. After joining, the data page 2 and the textile connecting element 6 are generally optically inseparable from the observer.

Fig. 3 shows the section of the overlapping area of the data carrier 2 before a security feature has been formed.

In Fig. 4 the section of the overlapping area of the data carrier 1 is shown schematically. By laser processing, a security feature 14, here for example the letter "A", is now formed in the overlapping area. The visual impression of the security feature 14 results from a local blackening 18 of parts of both the laser-doped layer 5 and the textile connecting element 6. Seen from above, the security feature 14 appears sharply and uniformly formed.

In order to falsify the data carrier 2, for example, the data page 2 must be separated from the textile connecting element 6 and exchanged for another data page. In order to gain the impression of authenticity, however, the security feature 14 must then be precisely reproduced. This is made more difficult because the security feature 14 is formed both in the data page, here in the laser-doped layer 5, and in the textile connecting element 6.

The result of a separation of data page 2 and textile connecting element 6 is shown schematically in FIGS Figures 5 and 6 shown. Fig. 5 shows the separated textile connecting element 6 and lying on this information component of the security element 14. It can be clearly seen that it is only a part of the security feature 14. The data page 2 after the separation is in Fig. 6 shown. Again, it can be seen clearly that only a part of the security feature 14 has remained on the laser-doped film 5. If a new data page is now to be connected to the original textile connecting element 6, the new data page would either have to have exactly the same local blackening 18 as the original data page 2, or laser processing would have to be performed again after connecting the new data page to the textile connecting element 6 be performed to blacken very precisely only the flaws 19 where there is no local blackening 18 more. This is possible only with a very great effort, so that a forgery of the data carrier 1 is made difficult or impossible.

Fig. 7 shows a further embodiment. The illustrated data carrier 1 comprises a data page 2 and a connecting element 3, which overlap in an overlapping area 4. The data page 2 comprises two laser-doped layers 5 and a further layer 17. The connecting element 3 is formed as an elastic, transparent film 7 with laser doping. If a security feature is to be formed in the overlapping area, a laser processing of the laser-doped films 5 and the elastic, transparent film 7 with laser doping is carried out analogously to the explanations given in the preceding figures. Local blackening creates the print image of the security feature. Just as for the textile fastener in the FIGS. 3 to 6 shown, the information components of the security feature are partially both in the laser-doped films 5 and partially in the elastic, transparent film 7. Since the data page 2 and the connecting element 3 are materially interconnected and the laser-doped films 5 and the elastic, transparent film 7 of the connecting element 3 can no longer be flat and just detached from each other, a separation of the data card destruction of the printed image of the security feature result. A forgery of the data carrier 1 by exchanging the data page 2 is therefore made much more difficult or impossible.

Another embodiment is in Fig. 8 shown. It is similar to the one in Fig. 7 shown embodiment. However, one of the laser-doped films 5 was replaced by a transparent film 8 without laser doping. Such a film may, for example, serve to protect the surface from abrasion or scratching. It is then possible in this embodiment to perform laser processing through the transparent film 8. The formation of a security feature in the overlap region 4 then takes place in such a way that the information components are again formed both partially in the laser-doped film 5 and in the elastic, transparent film 7.

An embodiment of the invention is in the FIGS. 9a as an outline and in Fig. 9b shown as a plan view of the disk 1. In a transition area 9, which comprises both at least part of the overlapping area 4 and a border area 20 of the data page 2, a security feature 14 is designed such that it overlies a border line 21 both partially in the overlapping area 4 and in the border area 20. The security feature 14 is also formed in this embodiment by means of laser processing. If the data page 2 is removed later, the security feature 14 is destroyed and an exchanged data page would have to replicate the partially destroyed security feature 14 at the borderline 21 and in the overlap area 4 with local blackouts. Since this is impossible or only with a very great effort is achievable, thus a forgery is made difficult or impossible.

Fig. 10 shows a schematic flow diagram of the method. In a first method step, a data page is provided 100. The data page may already include personalized information and / or security features. The parenthesized phrase "(personalized)" each indicates that this feature is optional. Furthermore, a connecting element 101 is provided, which may be, for example, textile connecting elements, foils or the like. Also, the connection element may already include personalized and / or other information, as well as security features. The data page and the connector are then arranged 102 so that they overlap in an overlap area. In the next method step, the data page and the connecting element are connected to each other 104. This can be done for example by a common method, such as gluing, welding, riveting, etc. For example, such a connection can be formed by means of ultrasonic welding. Subsequently, data for a security feature is provided or received 104. This may be, in particular, personalized data. Subsequently, the formation 105 of a security feature in the overlapping area is performed by laser processing, wherein the received or provided data are used. The information components of the security feature according to the invention are formed both partially in the data page and partly in the connection element.

Optionally alternatively or additionally, in one method step, the security feature or another security feature can be formed in a transition region. For this purpose, data is again provided or received 106, which may include in particular personalized data. Subsequently, on the basis of this data, a laser processing of the transition region between the overlapping region and an adjoining border region of the data side, so that the further security feature is formed there 107. Here, the security feature over a boundary line between the overlap region and the adjacent border region of the data side away both partially be formed in the border area as well as partially in the overlapping area.

If a ready-connected data carrier is already available, the method can alternatively also start only from method step 104, so that method steps 100 to 103 are dispensed with.

In the described embodiments, the connection element is often shown as "on" the data page. However, it is also possible for the connection element to be introduced in a recess or, in particular if it is designed as a fabric, to be "fused" into one or more layers or layers of the data side in the overlapping region. The various embodiments are also executable in such variants. Thus, the fabric, which itself may or may not be doped with laser, may be melted "from above" into a laser-doped layer, including a non-laser-doped layer and again including another laser-doped layer. In such an embodiment, it is possible to carry out laser markings both in the laser-doped layer and the tissue as well as in the further laser-doped layer. Even if the entire laser-doped layer is removed with the tissue in a counterfeiting attempt. Remains part of the laser mark in the overlap area. In the described embodiment it is assumed that the described layers are transparent, in particular clear.

In a modification, the melted fabric is laser doped, but the layer in which it is melted is not. However, a layer arranged thereunder is again laser-doped, with all these layers being transparent, preferably clear. The fabric is also formed at least partially transparent fibers and has a mesh size, so that a mark in the underlying laser-doped layer is possible between the fibers and is carried out. In order to verify a genuine security document, it is possible to check whether the markings are formed in two planes in the tissue and the laser doped layer underneath, preferably separated by a transparent, unmarked layer. With simple optical aids, such as a microscope, this can be tested.

It is understood that many more variations are possible.
