Description

Smart card with buffer material {SMART CARD APPLIED BUFFER MATERIALS}

The present invention relates to a smart card, and more specifically, by forming an image member and a buffer material layer on the surface, and mounting a high-brightness LED, not only can prevent damage and improve the appearance, but also expand the range of application. It's about making a smart card.

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.

Among these, in the case of a traffic card, a certain amount of money is charged in advance, and when a bus or subway is used, the vehicle is operated in a form of reducing the transportation fee from a prepaid amount when it comes close to the terminal installed in the bus. The traffic card contains a semiconductor chip, or IC, that is smaller than the pinky fingernail, and there are three main roles. The first is to manage the amount of money, to store information about a certain amount of money through charging, and to continuously change the content of the stored information every time you use the bus or subway. The second is the transmission of information. A traffic card, a contactless card, is located near a terminal installed in a bus or subway, and information in a semiconductor chip is transmitted to the terminal. In this way, a traffic card and a terminal installed in a bus or subway communicate information with each other. Can send and receive The third role is about electricity. Electricity is required to operate the semiconductor chip in the transportation card and to send and receive information through radio waves, but there is no battery inside the transportation card. Instead, the terminal installed in the bus or subway has a first coil to generate a constantly changing magnetic field, and the transportation card is equipped with a second coil along the circumference of the card. Therefore, when the traffic card approaches the terminal, an induced current is generated in the second coil, and the electricity generated at this time is very weak, but sufficient to operate the semiconductor chip.

The electromagnetic waves (or magnetic fields) generated by these induced currents depend on the contents recorded on the traffic card, and the terminal of the bus or subway reads the electromagnetic waves and checks the balance. Each time this circuit is operated, the amount of money stored in the memory in the card circuit is reduced. On the other hand, the chip embedded in the transportation credit card contains information such as card number and current usage fee.

As described above, since the traffic card has a semiconductor chip embedded therein, the thickness of the card is considerably thick, and if the traffic card is bent, the internal circuit may be damaged. 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, in Korean Utility Model Application No. 2004-20497, a coating layer in which a predetermined amount of pearl material, which is a glitter component, and a fluorescent paint is formed on a transparent epoxy resin on the surface of a traffic card, The coating layer is coated with a water-soluble U / V coating stock solution containing a fragrance. According to this application, it is possible to protect the traffic card itself, but the coating layer is already coated on the surface of the traffic card is determined design has a disadvantage that the function to improve the appearance is weak.

On the other hand, when the traffic card is in contact with the terminal of the bus or subway, the amount used or the remaining amount is displayed, but it is often difficult to check whether the fare has been processed unless you have bad eyes or care. And because the operation of the terminal was not smooth as it was changed to a new transportation system, when a contact card was contacted with the terminal, it often sent a message that it had not been processed. It raises doubts about traffic card users. In particular, the hearing impaired person may be disadvantaged when they get on or off despite the message that the fare has not been processed by the transportation card.

Accordingly, it is necessary to search for a method of improving the appearance of the traffic card so as not to be deformed by an external impact or force and to change the design of the traffic card. In addition, it is necessary to find a way to easily recognize the traffic card fare processing whether the user can easily recognize.

Accordingly, an object of the present invention is to provide a smart card which can prevent deformation due to external impact or force and improve the appearance.

Another object of the present invention is to provide a smart card that can expand the application range by embedding a high-brightness LED.

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 directly print a printed object on a printing plate, but transfers it to a rubber blanket that acts as an intermediary, and then prints it on paper. It is a technology that can be printed on. 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.

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, wherein 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. 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, by mounting a separate switch 80 may be configured to operate only the sound source IC.

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.

On the other hand, in the embodiment shown in Figures 3 to 4, the image member 120 and the buffer layer 130 is provided only on the front of the smart card 110, LED (on the front side of the smart card 110) 150) is installed. When the smart card 110 is brought close to the terminal, the LED 150 emits electricity by being supplied with electricity by an induced current formed in the coil. Therefore, the LED 150 emits light at the same time as the microprocessor in the smart card 110 is driven, and the user can determine whether the smart card 110 transmits and receives information with the terminal according to whether the LED 150 is turned on. have.

On the other hand, the amount of current supplied to the LED 150 may not be sufficient only by the induction current formed in the coil, and in this case, a separate power supply source may be provided. As the power supply source, as illustrated in FIGS. 3 to 6, the solar light collecting plate 155 may be used, and electricity may be generated using solar heat collected by the solar light collecting plate 155. In addition, a battery commonly used as a power source may be used, and it is preferable to use a light and small mercury cell or an internal battery. When the battery is used in this way, as described above, a separate switch 80 may be mounted to turn on the LED 150 when the user desires it.

Meanwhile, in the above-described embodiment, the image member 120 and the buffer material layer 130 are provided only on the front surface of the smart card 110, but as shown in FIGS. 5 to 7, the front surface of the smart card 210 and the like. The image member 220 and the buffer material layer 230 may be formed on the back surface, respectively. In this case, as described above, the image member 220 may be formed using one of a direct printing method, a method using a polarizing film, a method using a PVC plate, and a method using photo paper. In addition, the front image member 220 and the rear image member 220 may be formed using the same method, or may be formed using different methods. For example, the front and rear image members 220 may be formed using a polarizing film or photo paper. In addition, the printing method may be directly used only on the front surface, and the polarizing film or photo paper may be used on the rear surface, so that the method of forming the image member 220 on the front and rear surfaces may be different.

In addition, since the smart card 210 of FIGS. 5 to 6 forms the buffer material layer 230 on the front and the back, a guide 215 for preventing the leakage of epoxy is provided on the front and the back of the smart card 210. Are formed so as to protrude each.

In this way, the smart card 10, by forming the image member 20 and the buffer layer 30 on one side or both sides of the front and back, by diversifying the design of the smart card 10 to the user's taste Can respond to. Therefore, the user can be satisfied and the appearance can be improved. In addition, since the buffer material layer 30 plays a dual role of protecting the smart card 10, it is possible to prevent damage to the smart card 10.

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 design idea as described above is not limited to smart cards, it can be applied to any other card, 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 an example, and various modifications may be made without departing from the technical spirit of the present invention.
