The technical field

The present invention relates to chip cards, in particular non-contact or combined contact and contactless smart card antenna which is made on a substrate of paper.

Prior art

The contactless chip card is increasingly being used in various fields. So, in the field of transport it was developed as a means of payment. This also applies to the electronic wallet. Many companies use a means of identification of staff using contactless smart cards.

The exchange of information between the contactless card and the associated reading device is performed by remote electromagnetic coupling between the antenna performed in a contactless card, and the second antenna in the reader. For creating, storing and processing information in the map has a microchip or an electronic module connected to the antenna. Typically, an antenna and a microchip located on the insulating substrate, made of plastic - polyvinyl chloride (PVC), polyester (PE), polycarbonate (PC). The antenna is performed by chemical printing from copper or aluminum on the substrate or in the form of a coil of electrically conductive metal wire.

Map is often performed in the form of a monoblock. The antenna substrate is placed between two layers of the eraser - PVC, PE, PC, acrylonitrilebutadienestyrene (ABS), forming the upper and lower housing of the card, and put termopane by hot lamination under pressure. The chip or module connected to the antenna using a conductive or equivalent adhesive to ensure electrical contact.

However, this method has several major drawbacks. The main one is that when termopane plastic performed during lamination, get a card with a mediocre mechanical properties in relation to compensation of the stresses to which it is subjected when in use. When exposed to large stresses twisting or bending of the total voltage value is transmitted to the microchip or an electronic module, in particular at the point of bonding, providing the electrical connection. The mechanical strength of the bonding points is undergoing considerable stress and can lead to disconnection module/antenna or the chip/antenna. Consequently, it may rupture and the antenna.

This feature is used by scammers for a broad introduction of smart cards among the population.

Not to mention organized on a large scale fraud, which requires large investments and highly skilled technical specialists and to the E. is playing card by using another object, individual fraud is the most harmful because it affects the interests of consumers.

You can distinguish between accidental fraud, which map to use in purposes other than those for which it was intended, or do not comply with the conditions of use prescribed by the manufacturer.

There is also indirect intentional fraud, which is that a user who is not too knowledgeable in technical matters, trying to get through card services, which it is not programmed. For example, people trying to get money from an ATM using the card, which serves as a travel tool.

Finally, the last example of fraud is deliberate outright fraud. In this case, the user has well studied the card and knows her shortcomings. It is relatively easy to damage the card by repeated bending in cases where the credit card is a phone card, for travel on public transport card to pay for travel on toll roads) and credit has expired or nearly expired, and subsequently difficult to prove that the card is damaged intentionally. In this case, you can disconnect the antenna or connection microchip or module before the card is marked. Actually, plastic can be significant is considerable damage, while leaving no visual traces.

In all these three cases of fraud can be argued that the card is manufactured with a defect, and try to exchange it or get its value from the manufacturer. The latter is faced with a difficult dilemma, as he simultaneously wants to look good in the eyes of normal customers and not to fall into the same time too expensive situation compensation in case of fraud.

Another disadvantage of these cards is that they are made by complex layers of plastic material, joined by gluing or thermopile and having different coefficients of thermal expansion. Consequently systematically causes irreversible deformation maps (curl, warp), is not acceptable to the user, the cards have insufficient mechanical strength for regulatory or equivalent tests.

In addition, thermomechanical properties of PVC mediocre. During lamination is considerable fluidity of the material, where not saved the form of an antenna. This leads to unstable operation of the antenna, so as to change the electrical parameters such as inductance and resistance. What's worse, often there is a gap antennas in areas where there are significant shear stress. In particular, it proishodit the corners or at the level of the electrical connections.

The total thickness of the laminated cards ISO ranges from 780 to 840 microns. Given the fluidity of the material, it is difficult to ensure that users have normal characteristics of the card.

Another disadvantage of the cards is that after lamination on printed enclosures cards become visible traces of copper tracks. Although it does not affect the normal operation of the card, users put producers in the guilt of this defect, as impairing the aesthetic appearance of the map.

In addition, the production cost of the card this way too high, so you can talk about the real increase in their consumption.

Summary of the invention

The present invention is to eliminate these disadvantages by developing a new non-contact or combined contact and contactless smart cards, allowing you to limit the possibility of fraud by preserving traces of deliberate attempts to damage and at the same time to increase its deformation strength, that is, to keep its shape, which allows to guarantee the integrity of the electrical parameters.

The problem is solved in that the proposed non-contact or combined contact and contactless chip card containing the antenna on the substrate, and the antenna comprises at least one coil, which is made on the substrate, the stencil is the first method of printing using a conductive ink, two corps of the card on each side of the substrate, each of which consists of at least one layer of plastic, and one microchip or one module connected to the antenna. The substrate is made of paper and includes cut-outs in each corner, at the level of which is soldered to each other two corps of the map, the map in the crook gets the opportunity to delaminate at the place of impact of the efforts of the bend, which allows to detect intentional damage, because the card retains traces of the bend.

A detailed description of the preferred variant embodiment of the invention

The chip card in accordance with the present invention includes a paper substrate 10 (Fig 1), which by screen printing the printed antenna. The antenna contains two coils 12 and 14 are made with conductive polymer coating that is applied by screen method and containing electrically conductive components, such as silver, copper or carbon. Each of the coils has one end connected to one of the contact pads of the antenna connection module, also applied by screen method. When this coil 12 is connected with the contact lining 16 and the coil 14 to contact with the lining 18. The coils are interconnected electric jumper called "cross-over" (not shown). By screen printing between the electrical jumper and coil 12 is applied an insulating strip 20 of dielectric ink. The antenna is shown inverted relative to the normal to the drawing of the antenna chip-card format ISO. This configuration allows to obtain a combined contact and contactless chip card with a cavity for installation of the module produced by milling in the card case, the opposite side of the substrate with screen imprint, i.e. to use card in contact with the side of the substrate without screen-print.

Thus, if the substrate is inverted (contact pads are on the left) (figure 2), we can see that the contact pads of the module are in the standard place, as provided for cards ISO format.

In the case of contactless smart cards (figure 5 and 6). the drawing is not inverted. The microchip is positioned between the antenna substrate and one of the buildings, the card does not contain a cavity made by milling, so the antenna needs no protection. In this case, the card design is a classic.

Combined contact and contactless chip card (3) in the final configuration contains a cutout 22 in each corner of the substrate. When laminating the card case 24 made of plastic connected by termopane at the level of the notches 22. As the paper weight has a weak internal clutch when exposed to stress in shear, the core of the paper has a tendency to stratification. This physical property was used for making maps with integrated marker of stress. When you lock the corners of the map by means of soldering between the two housings card all voltages are transmitted to the inside of the card in the place of effort, when the map start to bend. With considerable effort, the paper splits, and the map is revealed to p is LEGO separating the two parts apart (part, containing the antenna continues to work). Soldering of buildings map in the corners allows the map to remain functional. Using the paper and its properties internal clutch, you can get the token voltages with adjustable sensitivity.

As plastic to run housings card use polyvinyl chloride (PVC), polyester (PE, PEG), polycarbonate (PC) or acrylonitrilebutadienestyrene (ABS). The module 26 is installed in the cavity and connected with the antenna. Figure 4 shows a cross-section of the map.

Paper substrate is placed between the two blocks of the map. Each card case is made of at least one sheet of plastic. In the preferred embodiment, each card is made of two sheets, one sheet forms the outer layer, another sheet - the inner layer. In accordance with one embodiment of these layers can have different hardness. In this case, the external layer is made of hard plastic and an inner layer of soft plastic with a low point Vicat (the temperature at which the plastic passes from the solid state to kauchukopodobnoe). The layers may have different thickness. In this case, the outer layer is thicker than the inner. The outer layer has a thickness of about 310 μm (microns), and the inner layer is about 80 μm. Preferably as plastic use PVC. H is worn by screen method, the antenna is located in the inner layer of the shell card. Due to the low hardness of your PVC during lamination of the card case the latter becomes fluid and enveloping his weight silk screen imprint. While the use of the card antenna is much better resists mechanical stress.

Paper substrate 28 (figure 4) antenna is placed in between the two buildings map containing three sheets in accordance with the preferred implementation. Each card contains a coating 30 of transparent PVC sheet or layer of varnish, with one sheet forms the outer layer 32 of rigid PVC, and one sheet forming the inner layer 34 made of soft PVC. The coating has a thickness of about 40 μm, the outer layer is about 275 microns and the inner layer is about 40 μm. The thickness of the last two layers may vary depending on the desired flexibility of the card. The module containing the two-way circuit 36 and the chip 38, protected with a protective layer of resin, placed in a specially constructed for this cavity. The cavity is made by milling the casing of the card, opposite side of the paper substrate with the antenna. The module is connected with the contact pads 40 of the antenna. Coil antenna 42 connected to one of the contact pads placed in the inner layer 34 of the enclosure cards from soft PVC. Module pasted on the map. For this we used two different the x-type glue. The first is a conductive adhesive 44 that connect the module with the contact pads of the antenna. Preferably this adhesive contains silver. The second adhesive 46 is used to secure the module on the map. For this purpose apply cyanoacrylate glue. You can also apply glue "hot melt" in the form of a film applied to the bottom side of the module before installing it in the map.

Figure 5 shows a contactless chip card in accordance with the present invention. The paper substrate of the antenna contains cutouts 44 in the corners. This substrate is placed between the buildings of the card 50. Unlike the combined contact and contactless cards each of the two buildings of the card does not contain a cavity. This card contains the module and the chip 52, which is sunk in the map and therefore not externally visible on its surface. Figure 6 shows a cross-section of this map.

Contactless card has the same design as a combined contact and contactless card. Paper substrate 54 is placed between the two blocks of the map. In accordance with the preferred implementation, each card is made of three sheets. Each card contains a cover 56, which may be made of transparent PVC sheet or layer of varnish, one sheet forming the outer layer 58 of rigid PVC, and one sheet forming the inner layer 60 of soft the CSOs PVC. Microchip 62 attached to the substrate 54 and is directly connected with the contact pads 64 of the antenna by means of a layer of conductive glue, ensuring the electrical connection. Round 68 antenna connected to one of the contact pads placed in the inner layer 60 enclosure cards from soft PVC. Thus, the microchip is between the paper substrate and one of the buildings of the map. Contactless card has a construction identical to the construction of the combined contact and contactless cards, and has the same properties.

In accordance with another variant of execution of at least one of the two buildings of the card is made of transparent sheets in order to be visible paper substrate and, in particular, graphic print on the substrate. Indeed, the technology of printing on a paper substrate known and well mastered. Get the quality high enough in resolution and color reproduction compared to the plastic substrate type PVC. This unique property of paper can be used for making cards, at least one side of the substrate which can be used for graphic printing high quality. So easy to place on the map advertising, trademark company-distributor or identification pictures, if we are talking about whether the data identification cards.

Chip card with a paper substrate in accordance with the present invention behaves quite differently than monoblock map of PVC. The paper is a fibrous material that absorbs some of the energy when the card is subjected to mechanical stresses. This cushioning effect weakens the elasticity inherent in the buildings of the map. During testing, the chip-card to bend and twist energy is in the center of the paper substrate and not in the joints of the module or microchip with an antenna, as in the close-coupled cards are made of PVC. This preserves the integrity of the antenna and the connection module or microchip.

Map in accordance with the present invention has two main qualities of great importance to users: protection of electrical components attached map greater strength, and property stratification of paper allows in case of loss of the card to check not been whether it is intensive bends of an illegal nature. When the user intentionally or unintentionally twists card paper substrate layers. Unlike cards PVC on this map appears trail from bending or twisting. If you twist or bend to reach the limit value, in the case of the map there is a crack. However, despite such a bend or curl, the card continues to function. This does not allow the t to the fraud to continue the attempts to bring the map down, then to demand reimbursement of its cost or its currency by the manufacturer, because on the map there are traces of such attempts.

In addition, the viscoelastic properties of polymer inks used in screen printing provides the best durability turns mechanical stresses during lamination. This avoids discontinuities in the antenna in places where it is subjected to considerable stresses on the shift.

Finally, the card is virtually no trace of a stencil imprint turns. This factor, though, and does not affect the functioning of the card is still quite important for distributors and users, with an emphasis on aesthetic criteria.
