Description

CARD-TYPE DATA CARRIER
[0001] The present invention relates to a card-shaped data carrier having a planar card body of multilayer construction.

[0002] It is known to employ as a security feature for paper-like value documents, such as bank notes or the like, security threads from different materials which are not copyable and can be forged only with disproportionate effort. For example, holographic security threads are applied in the form of diffractive surface elements on suitable plastic foils or are incorporated into these and integrated into security paper upon the paper manufacture which is then further processed to bank notes.

[0003] While the employment of security threads has proved useful in particular in the bank-note sector, card-shaped data carriers and identity cards from plastic are as a rule not equipped with security threads, because the optical effects known from the bank-note sector cannot readily be brought about in plastic cards.

[0004] In this respect, it is the object of the present invention to increase the anti-forgery security of card-shaped data carriers with the help of security threads.

[0005] This object is achieved by a card-shaped data carrier having the features of the independent claim. In the claims dependent thereon there are stated advantageous embodiments and developments of the invention.

[0006] A data carrier according to the invention comprises a planar card body of multilayer construction having a planar upper side and a planar underside. The data carrier is card-shaped and preferably configured as a plastic card, for example as a bank card or credit card, smart card, identity document or travel document or the like. The card body comprises several layers lying over each other, preferably plastic layers, among others, the combination according to the invention of a hologram strip and a planarly configured strip foil layer which has alternating or alternately arranged, transparent and substantially opaque strip-shaped regions. Seen from the upper side of the card body, the strip foil layer is arranged in front of the hologram strip, so that the hologram strip when viewed from the upper side in incident light is visible only through the transparent regions of the strip foil layer, while the substantially opaque regions of the strip foil layer cover the hologram strips in certain portions.

[0007] Particulars about the relative location or position of the individual layers of the card body are as a rule stated starting out from the upper side or underside of the card body. A layer which upon viewing the upper side of the data carrier lies in front of another layer thus lies over or above this other layer with regard to a sectional view or side view of the card body. A layer which upon viewing the underside of the data carrier lies in front of another layer therefore lies under or below the other layer with regard to a sectional view or side view of the card body.

[0008] The substantially opaque regions of the strip foil layer are neither completely opaque, thus impervious to light, nor are they transparent. Rather they have a perceptible translucency which, however, can be low. The level of opacity of the substantially opaque strips thus is such that in incident light, structures of the card body lying behind or under the substantially opaque regions are not visible, while such structures in transmitted light are visible diffuse, shadowlike or clouded due to a light-scattering and, where applicable, also reflective effect of the substantially opaque regions. The transmission (T) of the substantially opaque regions in this connection is smaller than one (T <1), preferably distinctly smaller than one, for example, T <0.8 or T <0.5.

[0009] The alternating strip-shaped regions of the strip foil layer can extend in parallel running over the entire area of the strip foil layer, thus cover this completely. Likewise the strip-shaped regions can be present only in a certain planar section of the strip foil layer, while the remainder of the strip foil layer is transparent, translucent or opaque.
Important for the invention is merely that the strip-shaped regions of the strip foil layer stand in planar relation to the hologram strip, thus cover this, so that the optical effect according to the invention comes about that the transparent and the substantially opaque strip-shaped regions cover and uncover the hologram strip in incident light alternatingly in certain portions.

[0010] Preferably the strip foil layer is arranged in the card body relative to the hologram strip such that the parallel alignment of the alternating, strip-shaped regions and the alignment of the hologram strip form an angle large enough, so that the hologram strip is visible through several of the transparent regions of the strip foil layer and is covered therebetween by several of the substantially opaque regions, so that the hologram strip when viewed from the upper side of the card body in incident light is visible merely in certain portions.

[0011] In this manner, upon viewing the upper side of the card body, the impression of a hologram strip arises which passes to the surface of the data carrier multiple times in certain portions and thereupon again disappears in the card body. The user of an inventive data carrier, such as a plastic identity document in ID-1 or ID-3 format according to ISO/IEC7810, knows this optically complex impression as an important security feature from the bank-note sector, which increases his or her confidence in the authenticity of the identity document. The design of the hologram strips can follow those of hologram security threads in the bank-note sector and be configured in particular between 1 and 2 mm wide and as a diffraction structure, where applicable, supplemented by demetalizations, metallic or color imprints, or other applications which bring about optically variable tilt or color change effects.

[0012] Preferably the card body above the strip foil layer and/or below the hologram strip comprises one, where applicable, also several transparent cover foil layers which form the upper side or underside of the card body. The hologram strip when viewed from the upper side of the card body in transmitted light is then distinctly visible through the transparent regions of the strip foil layer and is visible merely shadowlike through substantially opaque regions of the strip foil layer. As a result of this, the anti-forgery security of the data carrier is further increased because the different optical impressions in incident light and transmitted light no longer depend solely on the strip foil layer and the hologram strip alone, but additionally also on the further foil layers of the planar card body.

[0013] Such transparent cover layers on the upper side and/or the underside of the card body, which can be provided in all embodiments of the present invention, protect the arrangement of strip foil layer and hologram strip from wear and improve, where applicable, also the effect of the optical effects brought about. These cover foil layers are preferably made of a transparent plastic and can additionally be printed where the hologram strip is not visible, for example, with names, identification numbers, biometric or other security imprinting or the like.

[0014] In all embodiments of the present invention, the hologram strip is integrated preferably into a hologram foil layer, so that the data carrier according to the invention has a uniform thickness. The hologram foil layer is in this connection preferably a transparent plastic foil which comprises the hologram strip as a diffractive surface element. The hologram foil layer can also comprise several hologram strips which form a provided geometrical arrangement or have a mutual relation in another way, for example by mutually coordinated, optically variable images. The hologram foil layer can also comprise further security features which can then likewise be visible in certain portions through the strip foil layer, for example text or graphic elements, or also security features which become visible only under certain illumination conditions, for example under UV
or polarized light.

[0015] In a preferred embodiment of the present invention, the card body comprises a further strip foil layer below the hologram strip in addition to the hitherto described strip foil layer arranged above the hologram strip. In this embodiment, the hologram strip is enclosed by the two strip foil layers. Also the further strip foil layer has alternating, transparent and substantially opaque strip-shaped regions.

[0016] The two strip foil layers are aligned to each other in the card body preferably such that, on the one hand, their strip-shaped regions point in the identical direction and that, on the other hand, the transparent strip-shaped regions of the one strip foil layer, for instance the strip foil layer arranged above the hologram strip, lie as nearly as possible exactly above or in the substantially opaque strip-shaped regions of the respectively other strip foil layer, for instance the strip foil layer arranged below the hologram strip.
Preferably the coordination of the transparent regions of the one of the two strip foil layers is in exact register with the substantially opaque regions of the respectively other of the two strip foil layers.

[0017] In this manner the hologram strip is visible in certain portions when viewed from the upper side as well as the underside of the card body in incident light, while the hologram strips is visible alternatingly distinctly and shadowlike when viewed from the upper side as well as the underside of the card body in transmitted light. The hologram strip is distinctly visible in transmitted light namely through the transparent strip-shaped regions of the respectively viewed strip foil layer, while through the opaque strip-shaped regions of the respectively viewed strip foil layer those portions of the hologram strip are visible merely shadowlike which are in turn distinctly visible when viewed from the respectively other side of the card body through the transparent strip-shaped regions of the other strip foil layer.

[0018] For the viewer thus the impression arises here of a hologram strip which changes alternatingly back and forth between the upper side and the underside of the card body, and when it is distinctly visible on the side facing away from the viewer, it shines through the card body and is nevertheless perceived shadowlike.

[0019] Starting out from the above-described embodiment with only one strip foil layer, in a modified embodiment of the invention a planar, substantially opaque layer is arranged below the hologram strip, so that the hologram strip when viewed from the upper side in incident light is visible alternatingly in certain portions and is not visible when viewed from the underside, because the substantially opaque layer hides the view from there of the hologram strip in any case in incident light. In transmitted light the hologram strip when viewed from the upper side is alternatingly in certain portions distinctly and in certain portions merely shadowlike visible, while the hologram strips when viewed from the underside is continuously visible as a shadowlike strip.

[0020] A further embodiment develops the above-described embodiment to the effect that below the substantially opaque layer a further hologram strips and therebelow a further strip foil layer are arranged. The sequence of these layers in the card body when viewed from the upper side is thus: strip foil layer, hologram strip, substantially opaque layer, further hologram strip, further strip foil layer.

[0021] In this embodiment, in incident light when viewed from the upper side as well as from the underside of the data carrier, one of the two hologram strips is visible alternatingly in certain portions, while the other hologram strip lying in viewing direction beyond the substantially opaque layer is not visible. In turn, in transmitted light when viewed from the upper side and the underside respectively one of the two hologram strips is distinctly visible through the transparent regions of the relevant strip foil layer, while it is visible merely shadowlike through the substantially opaque regions of the relevant strip foil layer.

[0022] Also in the described embodiments having two hologram strips, these are present preferably in a hologram foil layer, so that the card body or data carrier has a constant thickness. Besides one or several hologram strips, these hologram foil layers can additionally have suitable security features which can also superimpose the relevant hologram strips.

[0023] All described embodiments can have on the upper side and/or the underside of the card body respectively at least one transparent cover foil layer, possibly even several.
Likewise, instead of the one substantially opaque layer described above, two or more substantially opaque layers lying one over each other can also be used, for example to suitably control the opacity of the entire layer. It is also possible to arrange two or even several hologram foil layers directly over each other in the card body, if this has advantages compared with an single hologram foil layer having two or more hologram strips, for example because a certain geometrical arrangement of the hologram strips is easier to realized in this manner.

[0024] In all embodiments, the extents of the described foil layers are such that the optical effects according to the invention are achieved. That is, the described foil layers are at least so large that the overlaps required according to the invention are possible.
Preferably the foil layers have, however, the extents of the entire card body or the card-shaped data carrier.

[0025] Preferably the card-shaped data carriers according to the invention are configured according to ISO/IEC7810 as identity documents in the format ID-1, ID-2 or ID-3 and can in this respect supply all further security features and functions which are usual for such identity documents, for example magnetic strip, microchip, impressing, printing or the like. In case of an identity document in the format ID-3, the data carrier according to the invention can form a data page which is incorporated into the multi-page identity document.

[0026] Further features and advantages of the invention will result from the following description of embodiments according to the invention as well as further alternative embodiments in connection with the drawings, which show:
Figure 1 a first preferred embodiment of the invention in cross section;
Figure 2 a second preferred embodiment of the invention in cross section (Fig. 2a) as well as an illustration of individual foil layers (Fig. 2b);
Figure 3 a third preferred embodiment of the invention in cross section;
Figure 4 a fourth preferred embodiment of the invention in cross section;
and Figure 5 a variant of the embodiment according to Figure 4 in cross section.

[0027] Figure 1 shows the card body 1 of a card-shaped data carrier or identity document in sectional view, consisting of two transparent cover layers 4 as well as a strip foil layer 3 arranged therebetween having strip-shaped, transparent regions 3a and strip-shaped, substantially opaque regions 3b as well as a hologram strip 2.

[0028] The sectional view through the card body 1 of the data carrier shown in Figures 1, 2a as well as 3 to 5 runs along the hologram strip 2 which, as is evident with reference to Figure 2b, is integrated into a hologram foil layer 20 which is transparent outside of the hologram strip 2. The format of the hologram foil layer 20, thus its planar extent, corresponds in this connection to that of the card body 1 as well as the format of the further layers, in particular of the strip foil layer 3 according to Figures 1, 3 and 5 or to the strip foil layers 31, 32 according to Figures 2 and 4. The hologram foil layer 20 can in principle have several hologram strips 2 which also do not necessarily have to run in parallel, but can, for example, enclose acute angles to increase the security of the data carrier by further optical effects.

[0029] The hologram strip 2 forms a hologram security thread of the data carrier. It is applied on the hologram foil layer 20 in the form of diffractive surface elements or is incorporated into this and can furthermore also have demetalizations and further, where applicable, hidden security features, for example machine-readable features which utilize the different physical effects such as magnetism, electrical conductivity, fluorescence or luminescence, or absorption properties or reflecting properties under UV
light, polarized light or laser light. For the same reason the hologram foil layer 20 can also have further security features which can either be arranged in the transparent region of the hologram foil layer 20 or overlap or cross the hologram strip 2.

[0030] The card-shaped data carrier represented in the Figures is configured in the format ID-1 according to ISO/IEC 180 and represents a bank card, credit card, debit card, a driving license, an electronic identity card or the like. In this connection the card body 1 can be equipped with further security features or identity features, for example with microchips which are capable of being read out contactlessly or using physical contacts, magnetic strips, biometric features or graphical elements such as security imprinting or the like.

[0031] The layer arrangement according to Figure 1 generates different optical effects, depending on whether the data carrier is viewed from the upper side 0 - thus through the upper transparent cover layer 4 onto the strip foil layer 3 and further onto the hologram strip 2 - or whether it is viewed from the underside U through the lower cover layer 4 directly onto the hologram strip 2. When viewed from the upper side 0, the hologram strip 2 in incident light is visible through the transparent regions 3a of the strip foil layer 3, while it is hidden through the substantially opaque regions of 3b. There thus arises the impression of a hologram security thread visible in certain portions. When viewed from the underside U, the hologram strip 2 is, however, completely visible in incident light.

[0032] In transmitted light, a more differentiated picture results, namely when viewed from the upper side 0, the hologram strip 2 is distinctly visible through the transparent regions 3a and visible merely shadowlike through the substantially opaque regions 3b.
Distinct differences thus result in transmitted light with regard to the visibility of the hologram strip 2, in fact, on the one hand, due to the optical density or transmission properties of the substantially opaque regions 3b and, on the other hand, due to a light-scattering or light-refractive effect of the substantially opaque regions 3b which is perceptible as a diffuse shadow effect.

[0033] When viewed in transmitted light from the underside U of the card body 1 the hologram strip 2 is in turn completely visible, because the transparent cover layer forming the underside 4 does not, or merely negligibly, impair the visibility of the hologram strip 2.

[0034] Figure 2a shows an embodiment in which the hologram strips 2 of two strip foil layers 31, 32 are planarly enclosed. In this connection the hologram strip 2 when viewed from the upper side 0 as well as from the underside U is visible in certain portions in incident light, namely, on the one hand, through the transparent regions 31a of the strip foil layer 31 and, on the other hand, through the transparent regions 32a of the strip layer 32.

[0035] Figure 2b illustrates the layer sequence of the card body 1 according to Figure 2a in plan view. Accordingly, the strip foil layer 31 is arranged over the hologram foil layer 20 and therebelow the strip foil layer 32 (symbolized by the plus signs). In incident light, there results on account of the interaction between the hologram foil layer 20 and the strip foil layer 31 or the strip foil layer 32 (symbolized by the equals signs) when viewed from the upper side 0 of the data carrier the view 33 and when viewed from the underside view U the view 34. In both incident light views 33, 34, the hologram strip 2 is merely visible alternatingly in certain portions through the respective transparent strips 31a, 32a, while it is covered in certain portions by the substantially opaque strips 31b, 32b (represented by dash lines) and is not visible there.

[0036] The alignment of the hologram strip 2 in the hologram foil layer 20, on the one hand, and the alignment of the strip-shaped regions 31a, 31b, 32a, 32b of the strip foil layers 31, 32, on the other hand, is preferably mutually perpendicular, so that hologram strip 2 running in horizontal direction in Figure 2b is hidden in certain portions by the parallel, substantially opaque regions of 31b, 32b running in vertical direction. The angle which the hologram strip 2 and the strip-shaped regions 31a, 31b, 32a, 32b enclose can deviate arbitrarily far from the represented right angle, as long as the hologram strip 2 is visible through the transparent regions 31a, 32a multiple times in certain portions and is covered by the substantially opaque regions of 31b, 32b multiple times in certain portions.

[0037] As is evident from Figures 2a and 2b, the two strip foil layers 31, 32 are arranged relative to each other such that respectively the transparent regions 31a, 32a of each strip foil layer 31, 32 lie as nearly as possible exactly over or under the substantially opaque regions 32b, 31b of the respectively other strip foil layer 32, 31. Preferably the alignment of the strip-shaped regions 31a relative to the strip-shaped regions 32b or the alignment of the strip-shaped regions 31b relative to the strip-shaped regions 32a are as nearly as possible in exact register, so that the hologram strip 2 is visible at every point of the card body 1 either from the upper side 0 or from the underside U.

[0038] The optical effect resulting therefrom is that of a hologram security thread switching back and forth alternatingly between upper side 0 and underside U
which is particularly difficult for counterfeiters to reproduce due to the arrangement of the strip film layers 31, 32 in exact register.

[0039] In transmitted light, the hologram strip 2 according to the embodiment according to Figure 2a is distinctly visible on both sides through the respective transparent regions 31a, 32a and is visible merely shadowlike through the substantially opaque regions of 31b, 32b. The effect perceptible on the upper side 0 of the card body 1 according to Figure 1 is therefore perceptible in the card body 1 according to Figure 2a from the upper side 0 as well as from the underside U.

[0040] Figure 3 shows a further embodiment of the invention in which a substantially opaque layer 5 is arranged between the transparent cover layers 4 below the hologram strip 2, so that when viewed from the upper side 0 of the card body 1 in incident light, the same optical effect results as in the embodiment according to Figure 1, whereas when viewed from the underside U the hologram strip 2 is not visible in incident light. In turn in transmitted light the hologram strip 2 when viewed from the underside U is visible continuously shadowlike.

[0041] The embodiment of Figure 4 in turn combines the layer arrangements according to the embodiments according to Figure 2a and Figure 3. In this connection, in the card body 1, a substantially opaque layer 5 is incorporated between both hologram strips 21, 22, which are present respectively within a separate hologram foil layer 20.
Between each of the two hologram strips 21, 22 and the corresponding transparent cover layer 4 forming the upper side 0 or underside U of the card body 1, respectively a strip foil layer 31, 32 is located which covers the respective hologram strip 21, 22 in the direction of the relevant side of the card body 1.

[0042] Seen from the upper side 0 as well as from the underside U of the card body 1, the respective hologram strip 21, 22 appears in incident light in certain portions interrupted, because it is visible merely though the transparent regions 31a, 32a, while the substantially opaque regions of 31b, 32b cover the view of the hologram strip 21, 22.
Depending on how the transparent regions 31a, 32a and the substantially opaque regions of 31b, 32b of the two strip foil layers 31, 32 are aligned to each other, further effects can result in transmitted light. If, as is represented in Figure 4, the transparent regions 31a, 32a of the one strip foil layer 31, 32 and substantially opaque regions 31b, 32b of the other strip foil layer 32, 31 lie over each other, the relevant hologram strip 21, 22 can be visible shadowlike in transmitted light when viewed from both sides of the card body through the relevant, substantially opaque regions of 31b, 32b, if the transmission properties of the substantially opaque layer 5 and the respective, substantially opaque regions 31b, 32b are accordingly mutually coordinated.

[0043] Figure 5 finally shows a variant of the embodiment according to Figure 3 in which the cover foil layers 4 consist respectively of several foil layers 41, 42.
Also the substantially opaque foil layer, as it is used in the embodiments according to Figure 3 or Figure 4, consists here of several substantially opaque foil layers 50, so that the transmission properties of the substantially opaque foil stack 50 can be adapted to the desired optical effects in transmitted light.

[0044] Likewise, as for the substantially opaque regions 3b, 31b, 32b of the strip foil layers 3, 31, 32, also the substantially opaque layers 5, 50 according to Figures 3, 4 and 5 have a perceptible translucency and light-scattering properties in transmitted light. By varying the thickness of individual substantially opaque layers 5 or using several substantially opaque layers 50, certain transmission properties perceivable in transmitted light can be achieved.

[0045] The described foil layers 20, 3, 31, 32, 4, 41, 42, 5, 50 are preferably made from plastic. In addition, regions or layers of other materials can also be incorporated into the card body, for example from paper, provided that this is expedient for the anti-forgery security or employment of the data carrier as an identity card. Furthermore, any further embodiment of the data carrier according to the invention is possible which requires its employment as an identity card.
