The present invention relates to a method of manufacturing a smart card, and more particularly, to a method of manufacturing a smart card that can shorten the working time and reduce the manufacturing cost by simplifying the manufacturing process.

In general, a smart card is a future prepaid card that can contain a large amount of information by mounting an integrated circuit memory device, also referred to as an IC (intergrated circuit card).

When smart cards are classified in terms of function and internal structure, they can be divided into three types, memory type, microprocessor built-in type and interactive type as follows.

First, the memory type smart card is a smart card that does not have a built-in microprocessor, and is mainly used in the fields that can be treated as securities such as public telephone cards or purchase rights, and includes a security logic in addition to the memory. There is also a method in which only memory is built in for pure data storage, such as medical insurance cards. EEPROM is mainly used as memory. Built-in microprocessor The smart card is equipped with a microprocessor and memory to perform advanced functions such as judgment, operation, and data protection. Interactive smartcards have a built-in microprocessor, memory, I / O protocols, and applications that enable interactive transfer of information.

Among such smart cards, a smart card having a microprocessor is mainly used, such as a traffic card, a door card key, a company card, a student card, and the like. Since smart cards with microprocessors have a built-in semiconductor chip, the thickness of the cards is considerably thick and the internal circuits may be damaged if the traffic card is bent. Therefore, if you carry it in your wallet with a lot of contents or put it in your bag, you may be shocked or deformed. In order to solve this problem, a user often prepares a separate transportation card storage wallet to store and use the transportation card, but in this case, it is inconvenient to find the transportation card storage wallet in the bag one by one. . In addition, since the traffic card is produced uniformly, the design is the same, so the appearance is not good, or even if the traffic card is changed between two different people until you check the balance.

Accordingly, in order to protect a traffic card, Korean Utility Model Application No. 2004-20497 (hereinafter, referred to as a prior art) mixes a predetermined amount of pearl material, which is a glitter component, and a fluorescent paint on a transparent epoxy resin on the surface of a traffic card. One coating layer is formed, and the coating layer is coated with a water-soluble U / V coating stock solution mixed with a fragrance.

The process of manufacturing a traffic card in this prior art, as shown in Figure 3 of the prior art. First, the upper surface and the lower surface of the PVC material having the IC chip and the antenna formed on the surface are coated with vinyl resin, and then the PVC material having the printed layer such as a picture, photo or text showing the background is adhered to the surface of the vinyl resin. Let's do it. Then, the vinyl resin is coated on the upper surface of the PVC material, and this process is a process of manufacturing a conventional traffic card. In addition to this process to form a coating layer having a predetermined thickness on both sides of the traffic card, the coating layer is formed so that the edge portion is thinner and thicker toward the center, it is bonded to the traffic card by thermal fusion. The coating layer is formed of a transparent epoxy resin.

The traffic card according to the prior art, it is possible to improve the durability of the traffic card by preventing the traffic card is folded or broken by the coating layer formed of an epoxy resin, a picture or photo showing the background formed on the bottom of the coating layer Or it is effective to protect printed layers, such as a character.

However, this prior art has the effect of improving the durability of the transportation card, but because the manufacturing process is complicated, the working time increases with the increase of labor, which has the problem of increasing the manufacturing cost. . Accordingly, by simplifying the process of manufacturing a traffic card with improved durability, it is necessary to find a manufacturing method that can shorten the working time and reduce the manufacturing cost.

Accordingly, an object of the present invention is to provide a method of manufacturing a smart card which can shorten the working time and reduce the manufacturing cost by simplifying the manufacturing process.

According to an aspect of the present invention, there is provided a method of manufacturing a smart card having an IC chip for storing data, the method comprising: providing a main panel on which an IC chip is mounted; Coupling a protective plate for protecting the main panel to one side of the main panel; Coupling an image member having an image including at least one of a photo, a picture, and a text to at least one side of the other side of the main panel and the protective plate; And forming a buffer material layer having a predetermined thickness on an upper surface of the image member.

The image member may be a photo paper of which a photograph is printed, and the photograph may be printed by printing with a heat resistant ink including a pigment.

The coupling of the image member may include attaching the image member to at least one side of the main panel and the protective plate using a double-sided adhesive tape.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of a smart card according to a first embodiment of the present invention, Figure 2 is a side cross-sectional view of the smart card of FIG.

Generally, the smart card 10 has an IC chip and a coil, and the outer surface is formed of several layers of PVC material. Here, the IC chip includes a memory for storing necessary information, and a microprocessor for processing operations such as arithmetic operation, the microprocessor is applied to the induced current generated in the coil in contact with the external terminal and the smart card 10. Works by

The smart card 10 has an image member 20 and a buffer layer 30 formed on one side thereof, and supplies power to a plurality of LEDs 50 and light emitting diodes 50 on the side thereof. The battery 70, which is a power supply unit, and a switch 80 for controlling the power from the battery 70 are mounted on the LED 50. In addition, the image member 20 'and the buffer material layer 30' are formed on the other side of the smart card 10 over the entire area.

Here, the image member 20 may be provided by forming all kinds of images that can be expressed, such as pictures, photographs, and letters, by various media or printing, and may be integrally or separated from the smart card 10 according to the method of forming the same. Can be manufactured.

The image member 20 of FIGS. 1 and 2 is formed by printing on the surface of the smart card 10 and may be used in various printing methods. As the printing method performed on the smart card 10, a printing method belonging to a flat plate among three plate types of a convex plate, a concave plate, and a flat plate is used. Among them, a printing method such as laser printing, offset printing, screen printing, flexography, etc. may be used. Can be.

Laser printing is a method of marking using a laser, and materials that can be laser printed include metal, plastic, wood, leather, paper, silicon, and glass. Laser printing uses three methods of digging and marking grooves on the stamping surface, discoloring and marking the surface of the material, and inflating and marking the surface to be processed.

Offset printing is one of the indirect printing methods. It is an indirect printing method that does not print directly onto a printed object from a printing plate, but transfers it to a rubber blanket that acts as an intermediary, and then prints on paper. It is a technology that can print on materials. Since metal flat printing is mostly printed by offset printing, offset printing is generally used synonymously with metal flat printing. Offset presses also include multi-color machines that can print two or more colors at the same time, and double-sided printers that print both sides of paper.

Screen printing is a printing method in which ink is passed through a mesh hole and transferred to paper using a plate composed of wires on a surface of which a mesh is attached to a wooden frame as one of trials. In the past it was called silk screen printing because it used silk mesh, but recently it is called screen printing because it uses nylon, tetron and stainless steel mesh. The screen printing machine has a flat printing machine and a curved printing machine. The flat printing machine prints paper, plastic, printed wiring board, and the like, and the curved printing machine prints on bottles and cups.

A flatbed press places a mesh screened screen on top of the paper and pushes the ink into the screen hole with a rubber spatula called a squeegee. The curved printing machine fixes the squeegee and rotates the printed object as the screen moves to print. Since this method is flexible on one side and has a low printing pressure, printing is possible on a wide range of materials such as paper, plastic, glass, and metal, and is used in many industrial fields.

Flexography is named for the use of flexible plates, and one of the convex plates is a method of printing with liquid ink using elastic resin or rubber convex plates. Initially it was called aniline printing because it used ink in which aniline dye was dissolved in alcohol. Flexography is also available for rotational printing, and there are drum, stack and in-line printers. In addition to paper, it is also printed on non-absorbent materials such as polyethylene and aluminum foil, and used for soft packaging materials, corrugated cardboard, and bagging.

In addition to the printing method, the image member 20 may be made of a polarizing film projecting an image such as a photo, a picture, a letter, and the like, and the image member 20 may be bonded to the surface of a smart card by bonding or the like. To prepare.

In addition, the image member 20 may be used to print photographs, pictures, letters, etc. on a PVC plate, print on photo paper, or print on a sheet of paper, it is preferable to use a heat-resistant ink. This is because when the buffer material layer 30 is formed of epoxy resin or the like, since the temperature is considerably high, when the ink or the like is not heat resistant, the photograph or image may be denatured. Then, the PVC plate or photo paper is bonded to the smart card 10 using a double-sided adhesive tape or adhesive. On the other hand, when using photo paper, if the epoxy directly contact the photo paper, pictures, pictures, letters may be damaged, so that the transparent film is mounted on the front of the photo paper.

The outer surface of the image member 20 is formed with a transparent buffer material layer 30 cured with an epoxy resin. Epoxy resin refers to a resin having an epoxy group in the resin, and is usually prepared by polymerizing bisphenol A and epichlorohydron under a catalyst. Epoxy resins are used in various applications due to their excellent mechanical and chemical properties and good processability, and are widely used in fields such as adhesives, paints, and linings. In recent years, it is also used as a material of soft stickers having a three-dimensional effect by pouring on the surface of the sticker or key ring 40 or the like.

On the other hand, in order to produce such a buffer material layer 30, the epoxy is mixed with a curing agent in a predetermined ratio and poured onto the surface of the smart card 10, whereby the epoxy flows from the surface of the smart card 10 to the outside. You can escape. In order to prevent this, as shown in FIG. 3, the smart card 10 is formed with a guide 15 protruding from the plate surface along the edge thereof. The height of the guide 15 is preferably formed at a height slightly lower than the height of the desired buffer material layer 30. This is because the epoxy resin has a viscosity, so that the area adjacent to the guide 15 by surface tension will be connected to the end of the guide 15 to form a natural curve even if the height of the epoxy resin is slightly higher. The guide 15 may be integrally formed on the smart card 10, but may be manufactured separately and coupled to the edge of the smart card 10, the surface in contact with the smart card 10, The guide 15 surrounding the edge of this surface may be integrally molded by using acrylic or the like.

The plurality of LEDs 50 mounted on one side of the smart card 10 are high brightness LEDs, and are mounted in one line along one side direction. Each LED 50 may have the same color or a different color from each other and is powered from the battery 70. Power from the battery 70 is interrupted by the switch 80, and when the switch 80 is turned on or pressurized, the power from the battery 70 is supplied to each LED 50. At this time, power may be supplied to each LED simultaneously or sequentially.

On the other hand, one side of the smart card 10 is equipped with a sound source IC (not shown) for generating sound, and is operated by the switch 80 described above. Therefore, when the switch 80 is pressed, the LED 50 emits light and simultaneously generates sound. Of course, it may be configured to operate only the sound source IC by mounting a separate switch (80).

One side of the smart card 10 is formed with a fastening hole 17 for mounting a key ring 40 or a mobile phone ring for easy portability, the fastening hole 17 is a smart card 10 itself, smart It is formed through the image member 20 and the buffer material layer 30 is coupled to the front of the card 10.

The manufacturing process of manufacturing the smart card 10 will be described with reference to FIG. 3 as follows. 3 shows a process of manufacturing the smart card 10 in a small amount by hand.

In the prior art, after completing the process of manufacturing the smart card 10, the PVC material and the vinyl resin formed with a picture, a picture, a character, etc. were sequentially combined. However, in the present manufacturing process, the manufacturing process of the smart card 10 itself only by attaching a protective plate 13 for protecting the IC chip and the antenna on the upper surface of the main panel 11 of the predetermined size where the IC chip and the antenna are formed. To complete. At this time, the main panel 11 and the protective plate 13 are all formed of PVC, the main panel 11 is formed with a guide protruding vertically from the plate surface along the four sides edge. On the other hand, the main panel 11 is equipped with an LED 50 and a switch 80, the protective plate 13, the image member 20, the epoxy 50 is coupled to the upper surface of the main panel 11 And through holes for exposing the switch 80 are formed, respectively.

The process so far is made by a process of a pre-process from the manufacturer producing the smart card 10 itself, and the subsequent process is manually performed by a company that upgrades the smart card 10 using the image member 20 and epoxy. Can be done.

When the manufacturing of the smart card 10 itself is completed in this way, the image member 20 is formed on the surface of the main panel 11 and the protective plate 13 to form a picture, a picture or a character, respectively, and at this time, the image member ( 20) may be formed of PVC or an overlay film. The bonding method is a double-sided tape, an adhesive or the like. The buffer material layer 30 using epoxy is formed on the surface of each of the image members 20, and the buffer material layer 30 directly applies epoxy to the surface of the image member 20, or the smart card 10. The epoxy molded according to the shape may be attached to the surface of the image member 20. Then, the image member 20 'and the buffer layer 30' are attached to the other side of the smart card 10, respectively.

Finally, a fastening hole 17 penetrating through the image member 20 and the buffer material layer 30 is formed on one side of the smart card 10, the key ring 40 in the fastening hole 17, the mobile phone ring By connecting one, it is possible to easily carry the smart card (10).

On the other hand, such a smart card 10, if produced in large quantities can be produced through a manufacturing process as shown in FIG.

In the mass production manufacturing process, the process of manufacturing the smart card itself and the process of forming the image member 20 and the buffer material layer 30 are performed together. First, the LED 50, the switch 80, and the like are mounted on the main panel 11 having a predetermined size in which the IC chip and the antenna are formed. Combine. In this case, the image member 20 coupled to the upper surface of the main panel 11 performs a function of protecting the IC chip and the antenna and improving the appearance of the smart card 10. Here, the main panel 11 is made of PVC, the image member 20 is formed of PVC or overlay film and the like. When the image member 20 is coupled in this way, a buffer material layer 30 using epoxy is formed on the surface thereof, and the buffer material layer 30 directly applies epoxy to the surface of the image member 20 or a smart card. Epoxy molded according to the shape of (10) can be formed by attaching to the surface of the image member (20). Then, the image member 20 'is attached to the other side of the main panel 11 and the buffer material layer 30' is formed.

As described above, in the prior art, the smart card itself is manufactured, and then, as the image member 20 and the epoxy are applied, four and eight layers on each side of the main panel 11 should be further formed. However, in the manufacturing method of the smart card, in the case of small quantity production, the protective plate 13 is coupled to the main panel 11, and the image member 20 and the buffer material layer 30 are formed. Only more layers are formed. In addition, in the case of mass production, by combining the image member 20 and the buffer material layer 30 directly on the main panel 11, only four more layers are formed. Therefore, when using the manufacturing method of the smart card, not only can protect the smart card and improve the appearance, but also the work process is reduced by half, compared to the prior art, the working time is shortened, smart card As the number of layers constituting the reduction is reduced, the manufacturing cost can be reduced.

In addition, since the smart card 10 may press the switch 80 at any time when the user wants to emit LEDs and generate sound, the smart card 10 may diversify the use of the smart card 10, such as a power failure or a dark place. The LED 50 can be safely moved by emitting light.

In addition, by configuring the LED 50 to light when the terminal is in contact or when the user needs, the user can easily determine whether the operation of the smart card 10 is properly performed.

Such a smart card can be applied to not only a bus card but also a card key for a door lock, and can easily find a door lock by emitting an LED 50 in front of a dark door, thereby easily unlocking the door lock.

On the other hand, the invention is not limited to smart cards, it can be applied to any other card of any shape, such as quadrilateral, polygon, circle, oval.

As described above, in the detailed description of the present invention, specific embodiments have been described, but it should be taken as exemplary, and various modifications may be made without departing from the technical spirit of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the claims below, but also by the equivalents of the claims.
