    [0001] [001] The present invention relates to a smart card that has a contact plate with printing on it. Fundamentals of the invention
    [0002] [002] A data carrier that has a contact card is usually referred to as a smart card (“smartcard”). These cards are usually the standard size and shape of a credit card and there is an integrated microchip inside the card body. The card provides not only memory capacity, but also computational capacity because the chip is capable of processing data. The main body of the card is typically made of plastic or a composite of paper and plastic, and there is a contact plate on the outer surface of the card that is in electrical communication with the microchip contained in the body of the card.
    [0003] [003] The contact plate (sometimes called the contact area) is approximately 1 cm2, comprising several gold-plated contact terminals. These terminals offer electrical connectivity when inserted into a card reader. The contact plate is on one side of the card and, when a card is inserted into a card reader in the correct orientation, the electrical contacts on the card reader connect to the contacts on the face of the card. When the card is inserted into a smartcard reader, there is an electrical connection such that data is read or written to the card via the chip on the card. It is through these physical touch points that transmissions of commands, data and card status occur. Such cards are usually used at retail outlets or in banking environments.
    [0004] [004] Credit cards or smartcards are often decorated with images, and these images may denote the card provider or the service offered by the card provider. Cards may also carry advertisements or photos of the cardholder, for example, in the case of driver's licenses or passports.
    [0005] [005] When including data on the surface of a card, there are two main processes for including this data: “initialization” and “personalization”.
    [0006] [006] “Initialization” is a term used mainly to describe the programming process of the smartcard chip with data that is the same for a batch of cards. An example of initialized data would be information on file structure and security key for a specific application. The initialization process may also include printing information, such as a logo, that is common to all cards in that batch.
    [0007] [007] “Personalization” is a general term used to describe the processes of printing (or embossing) data on the surface of the card, encoding the magnetic stripe on the card, and programming data on the smartcard chip. A more accurate definition of personalization is to carry out the processes described above (printing, coding and programming) for a card with data specific to an individual cardholder.
    [0008] [008] In many cases, the initialization process and the customization process are carried out together when the card is being issued.
    [0009] [009] When printing on a card, printing is on the card's surface, but not on the contact plate, in order to avoid reducing the electrical contact between the card and a reader. Until today, the contact plate has been small in size and therefore does not impair the overall appearance of the card. However, cards with larger contact plates have now been produced as more functions are added to the card, such as the inclusion of an antenna on the contact plate itself. The increased size of the contact plate further affects the visual appearance of the card to the user. An additional disadvantage is that there is less space on the card surface for printing data or advertising information. In addition, the contact plate may be more vulnerable to scratches.
    [0010] [0010] The present invention seeks to overcome the problems associated with the state of the art by offering a contact plate with a printed area on it. Brief description of the invention
    [0011] [0011] In accordance with a first embodiment of the invention, a smart card with a main card body and a contact plate is provided on a surface of the main card body, one area of the contact plate having a printed image about her.
    [0012] [0012] Preferably, the image is in a discrete region of the contact plate, leaving one or more areas of the contact plate without printed images.
    [0013] [0013] It is foreseen that these areas without printed images are the areas where there are external contacts for the contact plate.
    [0014] [0014] In a preferred arrangement, the printed image is printed over a monochrome base layer on the contact plate.
    [0015] [0015] Preferably, the printed image is printed with a security ink.
    [0016] [0016] In a preferred embodiment, the smart card is a smartcard, a bank card, a credit card, a debit card or a passport.
    [0017] [0017] The image is expected to correspond to an image on the main card body of the smart card.
    [0018] [0018] The contact plate and the main card body of the smart card are usually of different materials, but can be of the same material, such as, for example, PET.
    [0019] [0019] In accordance with another embodiment of the invention, a method of manufacturing a smart card is provided in which a contact plate is printed with an image and integrated into a main card body.
    [0020] [0020] In accordance with yet another embodiment of the invention, a method of manufacturing a smart card is provided in which a contact plate is integrated into a main card body and the contact plate is printed with an image.
    [0021] [0021] Preferably, the contact plate and the main card body are printed with images on a print pass.
    [0022] [0022] The contact plate can first be coated with a base layer, and the image is subsequently printed on the base layer.
    [0023] [0023] It is predicted that before printing the base layer or the image the external contacts on the contact plate are covered up.
    [0024] [0024] A positive image can be printed on the contact plate, for example, by laser printing, or a negative image can be formed by laser ablation.
    [0025] [0025] Preferably, the printing process is pad printing. However, other processes are envisaged, such as laser printing or D2T2 (Dye Diffusion Thermal Transfer) printing, which can be used. Brief description of the drawings
    [0026] - a Figura 1a mostra um smartcard de frente e a posição dos contatos externos sobre a placa de contato; - a Figura 1b mostra uma antena posicionada sobre uma placa de contato; - a Figura 1c mostra chips adicionais sobre uma placa de contato; - a Figura 2 mostra uma série de placas de contato sobre uma tarja com uma camada de base que foi impressa sobre as placas de contato; - a Figura 3a mostra um cartão inteligente com imagens correspondentes; - a Figura 3b mostra imagens para um lote de cartões; - a Figura 3c mostra imagens em outro lote de cartões; - a Figura 3d mostra um cartão fraudulento com imagens que não se correspondem; - a Figura 4 mostra um cartão que foi personalizado por ablação a laser; e - a Figura 5 mostra outra modalidade em que a imagem impressa é impressa parcialmente sobre a placa de contato e parcialmente no corpo do cartão. [0026] An embodiment of the invention will be described with reference and illustration of the attached drawings, by way of example only, in which: - Figure 1a shows a smartcard from the front and the position of the external contacts on the contact plate; - Figure 1b shows an antenna positioned on a contact plate; - Figure 1c shows additional chips on a contact plate; - Figure 2 shows a series of contact plates on a stripe with a base layer that was printed on the contact plates; Figure 3a shows a smart card with corresponding images; - Figure 3b shows images for a batch of cards; - Figure 3c shows images on another batch of cards; - Figure 3d shows a fraudulent card with images that do not match; - Figure 4 shows a card that has been personalized by laser ablation; and - Figure 5 shows another mode in which the printed image is printed partially on the contact plate and partially on the body of the card.
    [0027] [0027] A smart card is indicated in Fig. 1a by 1 (partial view), and the smart card has a main body 2 (shown partially) that is normally a plastic credit card, although data carriers such as identity documents, driving licenses or passports can be the smart card. The smart card has a contact plate on a surface that is indicated by 3, and that contact plate has external contacts 4 that are of a size determined according to the relevant standards established by ISO (International Organization for Standards). The external contacts are shown as two parallel rows, each having three or four contacts (although more or less contacts may be present). The external contacts must be of a particular size and be in a particular location on a card so that they can connect to the contacts of a receiving device. If a contact plate is large in size, then when the contact plate is integrated into the body of the smart card it can impair the appearance of the smart card when it is printed. Fig. 1b shows a contact plate that has an antenna 5 around the periphery of the contact plate, and that antenna is ideally located at a distance from the external contacts so that there is no interference. If more functions are needed for the card, it may have additional chips 6 as shown in Fig. 1c, which means that the contact plate becomes larger to accommodate these different elements. In addition, if a contact plate is fully metallized to ensure good contact, then contact plates will be very expensive. Typically, the metals used include ruthenium, palladium or gold, which are expensive materials.
    [0028] [0028] It was discovered that it is possible to metallize only the area necessary for external ISO contacts and decorate the remaining surface with screen printing as shown in Fig. 2. The screen printing area, which forms a base layer 7, extends over an area main of the contact plate 3. For printing, it is necessary to have an ink that can be applied on the contact plate, which is typically a predominantly metallic surface so that there is an adequate contact between the contact plate and the ink, in order to that it does not degrade or wear the contact plate from use. The contact plates are provided on a support stripe 8 and can be passed through a printer so that the area around the external contacts is covered with a layer of paint or polymer that is pigmented. External contacts are not printed and remain visible. The external contacts can be masked or covered with a material that prevents the ink from attaching to the external contacts.
    [0029] [0029] It has been discovered that, using a uniform colored background as a support for the contacts, a surface on which dedicated decorations can be applied to the card can be provided. The uniform background is typically a white or black layer of PET. The uniform layer can be applied before or after the contact plate is integrated into the body of the card, which is normally a plastic card. The use of a bottom can help to create a regular surface on the contact plate and also to create a regular print shade on the contact plate.
    [0030] [0030] The card is personalized as shown in Fig. 3. This is done by printing a dedicated image on the card, which can be a unique work of art for that card or a work that is limited to a particular print series. Innumerable techniques can be used, such as, for example, pad printing, thermal transfer ink diffusion printing (D2T2), inkjet or laser.
    [0031] [0031] In pad printing, an indirect offset printing process (rotogravure) is used, which involves an image being transferred from the printing plate (plate) through a silicone tablet over a substrate. The physical changes within the ink film in both the cliché and the tablet allow the ink film to leave the engraved image area in favor of adhering to the tablet, and subsequently freeing itself from the tablet in favor of adhering to the substrate. In the process, a sealed ink container (an inverted cup containing ink) is seated over the engraved art area of the printing plate, covering the image and filling it with ink. The sealed ink container moves away from the engraved art area, seizing any excess ink and exposing the engraved image, which is filled with ink. The top layer of paint becomes viscous as soon as it is exposed to air; this is how the ink adheres to the transfer pad and then to the substrate. The transfer pad presses down on the printing plate momentarily. While the tablet is compressed, it pushes air out and causes the paint to rise (transfer) from the engraved art area to the tablet. While the transfer pad moves forward, the ink container also moves to cover the area of art engraved on the printing plate. The ink container again fills the artistic image engraved on the plate with ink in preparation for the next cycle. The transfer pad compresses down over the substrate, transferring the ink layer seized from the printing plate to the surface of the substrate. Then, it lifts the substrate and returns to the neutral position, thus completing a printing cycle. This process can be performed for impressions on the contact plate in a localized area, leaving the external contacts without impressions. It can also be performed on a region of the card body. Typically, with this type of printing, lots of cards can be printed and these can be matched with lots of printed contact plates.
    [0032] [0032] The D2T2 printing system (Dye Diffusion Thermal Transfer) involves the use of sublimation ink in a loop of ink that is transferred and spread inside a substrate by the heat of a thermal head in the printing equipment. The optical density of the image depends on the glass transition temperature (Tg) of the material that forms the substrate, and therefore the adjustment of the optical density and the adhesion-slip behavior are important when printing a metallic contact plate.
    [0033] [0033] Laser printing is controlled by computer always for individualized artistic works to be printed on the contact plate and on the card body.
    [0034] [0034] Laser printing can be used in a direct mode (burning the surface of the contact plate) or it can be used indirectly where there is the printing of a layer of background ink, for example, by pad printing and subsequent performance of a local ablation of the paint layer to create a number or artwork on the contact plate and on the card holder.
    [0035] [0035] It is envisaged that specific selected inks can be used to provide another aspect of security to the card. Inks today can perform a variety of functions in addition to just safety. They may be impossible to copy, machine readable only, or reactive to changes in temperature or atmosphere, and these inks include safety inks, optical variable inks or UV and IR inks.
    [0036] [0036] Fig. 3a shows a card holder 1 that has the same artwork (9, 10) on the contact plate and on the card body. Figs. 3b and 3c show two batches of legitimate cards, with personalized matching works on each card. Fig. 3d shows a fraudulent card in which a contact plate from the lot shown in Fig. 3d has been included in a card body from the lot shown in Fig. 3c. If the same artwork is printed on the contact plate and on the card, then it is possible to associate the card and the module, so that in the event that a module is removed from a card to be reinstated on another card for fraudulent purposes, it it can be easily and immediately detected. In addition, this is a way of making it possible to track the printed batch of cards to which a particular card is related, thus offering a way of identifying when and where the card was manufactured or issued.
    [0037] [0037] Fig. 4 shows a card that has been personalized by laser ablation, in which the contact plate 3 is first printed with a bottom layer, for example, by pad printing or screen printing. Laser ablation is then used to remove the printed ink, allowing areas of the contact plate to be revealed as the desired logo.
    [0038] [0038] Fig. 5 shows another embodiment in which the printed image 9 is printed partially on the contact plate 3 and partially on the card body 2, so that the image is effectively presented in two portions. This has the advantage that it is not possible to remove the contact plate for placement in another card body, since, for the image to be complete, the two halves of the printed image 9 must match. This image matching offers one more security feature to ensure that the contact plate 3 is of a specific card body 2.
    [0039] [0039] Therefore, it can be seen that the ability to print in discrete areas on a contact plate while external contacts remain exposed allows for an enhanced security feature, in order to make it difficult for fraudsters to remove contact plates from cards to use them in a card body unrelated to the contact plate.
    [0040] [0040] It should be understood that the above modalities were presented only as an example of the invention, and that other modifications and improvements to this, as will be evident to technicians in the relevant sector, are considered within the broad scope and scope of this described invention. In addition, although individual modalities are discussed, the invention seeks to cover combinations of these modalities as well.
