Description

Accessory type transportation card {ACCESSORY-TYPE RF-ID CARD FOR TRANSPORTATION}

The present invention relates to an accessory type transportation card having a reliable operating performance as a compact sheet for accessory use.

In recent years, contactless wireless identification (RF-ID) cards and modules include traffic cards (bus cards), user entry / exit cards, wireless tags to prevent theft in stores, mobile phone payment modules, highway automatic toll collection machines (High Pass System). It is a field of great interest as many uses are made in our lives.

The current transportation card, which is represented by a bus card which is a kind of prepaid card and a subway card which is a kind of postpaid card, pays the transportation fee by a card payment method rather than cash. have.

As shown in FIG. 1, the prepaid transportation card according to the prior art is charged and accumulated in a certain amount of information in the memory area 2 mounted inside the card body 1, and installed at the entrance when using a bus or a train. It is based on a prepaid payment system that checks an RF (Radio Frequency) terminal system (including a card reader) so that the amount information corresponding to the corresponding fare is deducted, but it is inconvenient to recharge after use.

Another type of transportation card is a contactless RF transportation card (PLCC: package type of plastic leaded chip carrier), in which a contactless RF electronic chip 3 and a loop antenna 4 are also mounted inside a predetermined card body 1. It is based on a postpaid payment system that allows a user to carry a wallet or a bag and communicate with a card reader installed in a subway or a bus to settle the usage fee in a postpaid manner.

Here, the PLCC refers to a chip package type in which a lead terminal is vertically downward from the side and bent inward from the bottom of the chip.

Both the contactless card and the contact card have a similar configuration in that they are provided with a communication element, a memory element, and a loop-type antenna 4 necessary for the information processing function to communicate and supply power.

Such a transit card conforms to the ISO credit card standard, and has a flat surface of 86 mm x 6 mm in width and 1 mm or less in thickness (0.76 mm to 0.84 mm).

Here, the ISO credit card standards are 'Visa International Vendor Manufacturing Standard', 'Mastercard International Vendor Manufacturing Standard' and 'ISO 9001 QC Standard'.

A typical traffic card is ISO 7810, which defines the external dimensions as a magnetic strip card manufacturing standard, ISO 7816-1, which defines the physical characteristics of the card as a chip card manufacturing standard, and a card that defines the contact point and dimensions of the card. Complies with ISO 7816-2 and the technical specifications of ISO 7816-3, which define electrical signals and transmission protocols.

However, as the conventional traffic card is used in a state of being put in a wallet or the like, the user has to take out the wallet every time the user wants to use the traffic card and adds inconvenience to the receiver.

In addition, when the conventional traffic card is used in a wallet or the like, the output signal of the RF electronic chip embedded in the traffic card is weakened, and thus an error occurrence rate such as the receiver cannot read data transmitted from the RF electronic chip normally. This was very high and the recognition success rate was not good.

In addition, by mounting an RF electronic chip and a loop antenna, which are conventionally embedded in a traffic card, inside a mobile terminal or a battery thereof such as a mobile communication terminal, the mobile terminal can be used as a substitute for a traffic card without having a separate traffic card. However, the situation is still exposed to the hazards of electromagnetic waves.

In addition, in the case of a mobile terminal having a built-in RF electronic chip and a loop antenna, as the electromagnetic wave blocking means is applied, RF communication for forming induced electromotive force between the loop antenna and the card reader is disturbed in the operation thereof. Accordingly, the recognition distance is shortened, and thus, the communication is incomplete if the terminal is not approached to the card reader.

On the other hand, attempts and studies are being made to manufacture conventional transport cards in the form of miniaturized watches, key chains, accessories, labels and the like, but the following problems occur when simply manufacturing the transport cards in small sizes.

That is, in the case of the RF ID tag, the deviation of the recognition distance according to the miniaturization is greatly generated, which causes a large error rate.

The conventional traffic card uses a coil-type loop antenna made by simply winding a plurality of thin coils in a bundle, so that the overall thickness of the traffic card is relatively thick, and the recognition distance is very severe. According to the situation of approaching the card reader, the variation in the inductance of the loop antenna is generated, and thus, the recognition success rate is very low. Here, the problem of deviation of the recognition distance depends on the performance and design factor of the loop antenna.

In addition, the conventional traffic card is provided with a coiled loop antenna, which requires a separate mounting slit or ring-shaped mounting hole for mounting the loop antenna, so that the loop antenna assembly is relatively complicated. It has a hard disadvantage.

In addition, when forming irregularities such as embossed characters, texts, and images on the traffic card, it is necessary to mount the RF electronic chip to avoid the uneven portion, and at the same time, the connection work with the loop antenna or the position adjustment of the RF electronic chip must be performed. It's very hard.

In particular, the traffic card according to the prior art basically satisfies the performance, such as high security, high reliability, multi-function, and ease of use, but as it is manufactured in small size, the error rate is rapidly increased due to the short recognition distance or severe deviation of the recognition distance. It is true that chip mounting and antenna design are very difficult.

For example, the IDK50 key tag sold by ID Tech Co., Ltd. (CEO: Pil-Kyung Kang) is used as a passive type key ring that does not require a battery. It is inadequate to use, and as shown in the following product specification [Table 1], it is insufficient to be used in small size while providing reliability as a traffic card in consideration of its recognition distance, thickness, product operation stability and the like.

In the field of RFID ID tag technology, there have been attempts to manufacture small size in the shape of coin (or coin) or circular tag, but it does not provide a satisfactory recognition distance as a traffic card, and the technical specification and design of the antenna that can exhibit such performance. No technical specifications, such as patterns, are currently open or developed.

Accordingly, the present invention is to solve the above-mentioned problems in the prior art, while providing a layer type combination including a loop antenna and an RF electronic chip to secure reliability and excellent performance as a traffic card, The object of the present invention is to provide an accessory type transportation card that is light in weight, has a relatively good recognition distance, and has a free chip mounting direction, which is excellent in assembly and manufacturability.

The object of the present invention described above is an accessory type of transportation card that performs payment for a transportation card by an RFID electronic chip powered from a card reader through an access, wherein the main body has a ring hole penetrated in an eccentric position in a thickness direction. Wow; An antenna layer interposed between an upper cover layer and a lower cover layer each covered with a first coating film arranged on the top of the body and a second coating film arranged on the bottom of the body; The antenna layer is achieved by an accessory type traffic card, characterized in that a loop antenna or a wiring formed by etching is arranged on one of one surface and the other surface of a substrate.

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

In addition, the main body 100 has an antenna layer manufactured by mounting an RF electronic chip therein.

In the present invention, the combination of the layer type refers to an antenna layer that serves as a kind of small thin smart card, which is a combination of a substrate, a thin loop antenna, a wiring, and an RF electronic chip.

The RF electronic chip used in the present invention is a Mifare chip or an integrated circuit chip for a predetermined smart tag, and any short-range low-frequency chipset as is well known in the ordinary industry (traffic card manufacturer, RF tag manufacturer, etc.) Anything is available.

The Mipair RF IC chip used as an example in the present invention satisfies the technical specifications of the conventional bus and subway traffic cards mentioned in the prior art, and is currently installed in most traffic cards in Korea.

The main body 100 of the present invention is a smart disk having a circular disk-shaped smart RF-ID card, which has an outer shape of a small sheet having a total diameter of 33 mm to 36 mm and a thickness of 0.76 mm to 0.84 mm.

In addition, the material of the accessory-type traffic card of the present invention is designed to operate at 13.56 MHz by using any one of PVC, ABS, PE, PET (polyethylene terephthalate) which is a synthetic resin material for manufacturing a smart card. Here, for example, the upper cover layer and the lower cover layer forming the outside of the traffic card are made of PVC sheet, and the antenna layer laminated between the upper cover layer and the lower cover layer inside the traffic card is made of PET sheet. do.

The technical feature according to the first embodiment of the present invention is the operation of 16 MHz as a result of considering the predetermined dielectric constant of the upper and lower cover layers, the overall size (diameter 33 mm to 36 mm) and the thickness (0.76 mm to 0.84 mm). It is to provide a design technology and a chip mounting technology of the loop antenna 139 or antenna layer 130 having a resonance frequency. As a result, the main body 100 can be manufactured in a compact and thin sheet while providing an operating (resonant) frequency of 13.56 MHz as a traffic card.

In addition, the ad text consisting of the text phrase 111 and the image 112 is represented on one surface and the other surface of the main body 100 of the traffic card.

In addition, near the outer circumference eccentrically off the shaft center of the main body 100, the hole hole 101 for mounting the accessory ring is drilled in the thickness direction, thereby giving an intimacy like the outer disk-shaped accessory.

While the traffic card of the present invention does not use a coiled loop antenna, the technical standard of either the ISO 14443 format or the RF-ID ISO 15693 format using 13.56 MHz is suitable for the system of the traffic card as mentioned above. For reference, an antenna layer (or loop antenna) of a new etching method structure is used.

As shown in FIG. 3, the loop antenna 139 or the antenna layer 130 of the traffic card of the present invention is a multilayer loop antenna type, and is manufactured by a manufacturing process to be described in detail below. Not only does the recognition distance increase, but there is little variation in the recognition distance.

Here, in the multilayer loop antenna type, the extension terminals 131 and 132 are arranged on one surface (upper surface or lower surface) of the substrate 136 and the loop antenna 139 is disposed on the other surface (lower surface or upper surface). It means that the extension terminal 131, 132 and the loop antenna 139 is electrically connected in a direction passing through the substrate 136, the extension terminal and the loop on one surface (upper surface) of the predetermined substrate The concept is opposite to the single-layer loop antenna, which is inconvenient in chip mounting due to the presence of antennas.

Hereinafter, the manufacturing process of the antenna layer 130 in the traffic card of the present invention will be described.

The manufacturing process of the antenna layer 130 is largely formed by forming a plurality of through holes 135c (see FIG. 5) corresponding to the connection positions of the loop antenna 139 and the extension terminals 131 and 132, and through each of the through holes. Both surfaces of the substrate 136 are plated with a copper foil having a predetermined height in a state in which the hole 135c is formed, and as a result, the first and second throw holes may be electrically energized at the position of the through hole 135c. Forming a terminal and an antenna pattern on one surface and the other surface of the substrate, respectively, based on the first and second throw holes 135a and 135b; Performing etching (etching) corresponding to the terminal and antenna pattern.

First, in the through hole forming step, a predetermined micro-drilling machine is located at two positions of the substrate 136 in consideration of the mounting position of the RF electronic chip and the connection position of the loop antenna 139 and the extension terminals 131 and 132. The plurality of through holes 135c are drilled using the same. As the substrate 136 used herein, any one of a substrate, a gas, and a sheet (product sold by TORAY, Japan, Kolon, Korea, etc.) of 0.15 mm thick PET material may be used.

In the step of forming the first and second throw holes 135a and 135b, the upper surface (one surface) and the lower surface (the other surface) of the substrate 136, including the inner circumferential surface of the through hole 135c, may be formed of a metal sheet. By plating all by the normal plating method of plating, it has a laminated structure like an upper copper thin film, the board | substrate 136, and a lower copper thin film. In this case, the upper copper thin film and the lower copper thin film are in a state capable of conducting mutually through each of the first and second throw holes 135a and 135b.

In the terminal and antenna pattern forming step, at a predetermined position of the copper thin film on which the RF electronic chip of the substrate 136 is to be positioned, two firsts having a circular shape as a whole but slightly spaced apart from each other through an inner rectangular non-contact space The wiring pattern for the second chip fixing terminals 134a and 134b is formed.

In addition, as shown in the drawing, a wiring pattern is formed at a predetermined position of the copper thin film so that the first extension terminal 131 extends from the first chip fixing terminal 134a to the circular first contact 131a in the horizontal direction. The first throw hole 135a is positioned at the center of the first contact point 131a.

In addition, as shown in the drawing, the wiring pattern is formed at a predetermined position of the copper thin film so that the second extension terminal 132 extends from the second chip fixing terminal 134b to the circular second contact 132b in the vertical direction. The second throw hole 135b is positioned at the center of the second contact point 132b.

On the other hand, at a predetermined position of the lower copper thin film, a plurality of antenna lines each having an equally spaced antenna line width (w) of 0.25 mm and an interval (s) of 0.15 mm between antenna lines respectively correspond to a circumferential rate of increasing at a predetermined ratio. A loop antenna pattern for the loop antenna 139 is formed which is arranged in the circumferential direction by 12 revolutions.

At this time, the loop antenna pattern forms a loop antenna 139 close to a circular shape having a diameter of 32 mm inside a traffic card having a diameter of 33 mm to 36 mm so that the traffic card of the present invention exhibits superior performance than a general traffic card. At the same time, a ring hole 101 having a diameter of 3 mm to 4 mm can be disposed between the outer side of the loop antenna 139 and the inner circumference of the substrate 136.

That is, most of the loop antenna pattern except the ring hole 101 and the first contact point 131a has a closed curve circular ring shape, such as a clockwork, and has a circular third contact point at both ends of the loop antenna 139. While forming a circular fourth contact 139b with 139a, the third contact 139a coincides with the first contact 131a, and the fourth contact 139b is connected to the second contact 132b. The first and second throw holes 135a and 135b formed in the thickness direction of the substrate 136 at the center of each of the contacts 131a, 132b, 139a, and 139b have a predetermined shape to protect from etching. .

In particular, the loop antenna pattern is such that each of the antenna lines of the loop antenna 139 corresponds to the circumference of the ring hole 101 such that the first curved portion 137 having a 'U' shape is formed to be bent. It has a first curved pattern corresponding to the hole 101.

In addition, the second curved pattern of the loop antenna pattern may be formed such that each of the antenna lines of the loop antenna 139 corresponds to the circumference of the first contact point 131a so that the second curved portion 138 having a fan shape is bent. And a second curved pattern corresponding to the first contact point 131a.

In the etching step, the upper copper thin film except for the terminal and antenna pattern and the lower copper thin film are removed from the substrate 136 by a predetermined etching solution, such as a solution of ferric chloride, according to a conventional metal corrosion method. do.

In the antenna layer 130 which has been etched in this way, a loop antenna 139 having a closed curve circular ring shape, such as a clockwork, as described above, and wiring for connecting the loop antenna 139 to the RF electronic chip 200 are formed. .

In the description of the present invention, the wiring refers to a first contact 131a, a second contact 132b, a third contact 139a, and a second etching pattern formed on the surface of the substrate 136 by etching by various wiring patterns. Four-contact point 139b, first throw hole 135a, second throw hole 135b, first extension terminal 131, second extension terminal 132, first chip fixing terminal 134a, second chip Like the fixed terminal 134b, it means a current supply wiring.

Hereinafter, the electrical connection between the loop antenna 139 and the RF electronic chip 200 will be described.

The accessory type traffic card according to the first embodiment of the present invention is characterized in that the RF electronic chip 200 and the loop antenna 139 are arranged opposite to each other on the opposite side of the surface of the substrate 136.

The first chip terminal of the RF electronic chip 200 is connected to the first chip fixing terminal 134a through a bump, and the first chip terminal 134a extends in the horizontal direction. It is connected to the first contact point 131a through, the first contact point 131a is connected to the third contact point 139a located vertically in the thickness direction of the substrate 136 through the first throw hole (135a) The third contact 139a is connected to one end of the loop antenna 139, and one end of the loop antenna 139 has a closed curve circular ring shape, such as a clockwork, for 12 rotations of the loop antenna 139. Extends to the opposite end of the loop antenna, the opposite end of the loop antenna 139 is connected to the fourth contact 139b, and the fourth contact 139b is connected to the substrate through the second throw hole 135b. It is connected to the second contact point 132b located vertically in the thickness direction, and the second contact point 132b is connected to the second chip fixing terminal 134b through the second extension terminal 132. Connected to the second chip terminal 134b through another bump to the second chip terminal of the RF electronic chip 200, thereby converting the magnetic field signal into an electrical signal when approaching the card reader, thereby converting the RF electronic The power required for the operation of the chip 200 may be supplied.

In the antenna layer 130 of the present invention, the first and second chip fixing terminals 134a and 134b, the first and second extension terminals 131 and 132, and the first and second contact points on the upper surface of the substrate 136. 131a and 132b protrude at a constant height, respectively, while the loop antenna 139 and the third and fourth contacts 139a and 139b protrude at a constant height from the lower surface of the substrate 136, respectively. .

Such an opposing structure can transmit the compressive force to the antenna layer 130 at the time of the compression coupling between the upper and lower cover layers and the antenna layer 130, and as a result, to form an airtight coupling structure in the traffic card body. To help.

If a predetermined extension terminal and a predetermined loop antenna are formed to protrude only on either one of the upper surface or the lower surface of the substrate 136, such as a single-layer loop antenna type, the compression force is unbalanced when the upper and lower cover layers are compressed. Providing the upper and lower portions of the 130 and the unbalanced stress is generated, the present invention is characterized in that the structure is formed to prevent such unbalanced stress in advance.

On the other hand, the mounting position of the RF electronic chip is located in the direction in which the first and second extension terminals 131 and 132 are disposed from the contacts 131a, 132b, 139a and 139b having the first and second throw holes 135a and 135b. When the extension length is adjusted as necessary, the positions of the first and second chip fixing terminals 134a and 134b can be easily designed to meet the purpose of avoiding the embossing position of the traffic card or the predetermined hole drilling position. As a result, the mounting position of the RF electronic chip can be freely adjusted.

Therefore, in order to have the resonance frequency of 16 MHz in the antenna layer 130, the diameter of the loop antenna 139, the number of rotations of the antenna lines, and the interval between the antenna lines and the lines may be as shown in [Table 2] above. The loop antenna 139 of the present invention has an inductance size of 6.63 uH.

As shown in Figure 4, the main body 100 of the accessory-type traffic card of the present invention is that the ring holes 101 are respectively punched in the same position and are all punched in the same position, in order from top to bottom Arranged first coating film 119, the upper cover layer 110, the first inner layer 120, the adhesive layer is coated on both sides, the antenna layer 130, the second inner layer 140, the adhesive is coated on both sides, A lower cover layer 150 and a second coating layer 159.

As described above, the RF electronic chip 200 is mounted on the first and second chip fixing terminals 134a and 134b and then covered with a predetermined epoxy resin 210.

5 and 6, in the antenna layer 130, the through hole 135c is formed of a substrate 136 in order to form the first throw hole 135a or the second throw hole (not shown) in a plating manner. Is penetrated in the thickness direction.

On the inner circumferential surface of the through hole 135c, a first throw hole 135a plated with a copper thin film material by a predetermined thickness is formed, and of course, a second throw hole is formed in another through hole (not shown) in the same manner.
