Description

Technical Field

[0001] This invention relates to a contactless metal card with a light-emitting device and a method for manufacturing the same. Background Technology

[0002] Generally, based on the recording method, cards are divided into magnetic cards that use entries, smart cards that use IC cards, and hybrid cards that combine the two. Based on the reading method, smart cards are divided into contact cards, contactless cards, and combination cards that combine the two methods. Contactless cards are further divided into Near Field Communication (NFC) cards, which can only be read within a distance of a few centimeters to tens of centimeters, and RF cards, which can be read at a greater distance. Usually, cards that combine these methods are more common.

[0003] On the other hand, plastic cards are typically issued to allow specific members to defer payment for goods and services for a certain period. They are mainly used as credit cards, cash cards, transportation cards, etc., to replace cash, or widely used as various medical cards and membership cards. Currently, customers are offered a variety of plastic cards differentiated according to their credit rating.

[0004] Among them, special cards such as gold cards or platinum cards made for VIP customers with higher credit ratings are painted gold or silver to create a more luxurious feel.

[0005] However, the special card presents gold and silver by mixing gold or silver powder and printing it. Therefore, the gold and silver powder mixed in the pigment is not pure gold or pure silver. Moreover, it is mixed with other pigments and binders, so it cannot obtain the high gloss and texture of pure metal.

[0006] Furthermore, unlike pure metals whose luster or texture never changes, gold or silver powder can deteriorate depending on humidity or temperature conditions. Therefore, if plastic cards are used for a long time, the coating will discolor and deteriorate, resulting in problems such as reduced gloss, and ultimately failing to provide high-quality cards.

[0007] Therefore, metal cards made of metallic materials are currently being used as alternatives. Metal cards offer a sense of weight and are made of 0.6–0.7 mm thick metal to meet market demands, instead of the commonly used 0.3–0.4 mm thick metal.

[0008] However, the existing metal cards mentioned above are slotted metal cards containing PVC material that is harmful to the human body, thus posing a health risk. Apart from the metal material layer, there are no additional functional structural elements, making it difficult to provide the scarcity value of the product.

[0009] Furthermore, existing metal cards, apart from having a metal material layer, do not have any additional functional structural elements, making it difficult to provide the scarcity value of a PLCC as a commodity. Summary of the Invention

[0061] This invention can have various modifications and embodiments, with specific embodiments illustrated in the figures and described in detail. This is not to limit the invention to a particular implementation, but should be understood as corresponding to all modifications, equivalents, or alternatives within the spirit and technical scope of the invention for connecting and / or fixing structures extending in different directions.

[0062] The terminology used in this specification is for illustrative purposes only and is not intended to limit the invention. Unless the context clearly indicates otherwise, singular expressions include plural expressions.

[0063] In this specification, terms such as “comprising” or “having” are used to specify the presence of features, figures, steps, actions, structural elements, components or combinations thereof described in the specification, and do not preclude the presence or additional possibility of one or more other features, figures, steps, actions, structural elements, components or combinations thereof.

[0064] Hereinafter, with reference to the accompanying drawings, preferred embodiments of the contactless metal card and its manufacturing method of the present invention will be described.

[0065] Figure 1 This is a circuit diagram that includes a metal card and a card reader.

[0066] Reference Figure 1 The metal card of the present invention may include an antenna component 100 assembled with a metal body 200 made of metal material and provided with a primary coil antenna 110, a secondary coil antenna 120 and a light-emitting part 130, as well as a card chip 400.

[0067] The primary coil antenna 110 can communicate with the card chip 400, and the secondary coil antenna 120 can communicate with the reader chip 500. The primary coil antenna 110 and the secondary coil antenna 120 are arranged in a ring around the antenna component 100.

[0068] The starting point S1 of the primary coil antenna 110 is connected to the ending point E2 of the secondary coil antenna 120, and the ending point E1 of the primary coil antenna 110 can be electrically connected to the starting point S2 of the secondary coil antenna 120.

[0069] The structure described above can be achieved by combining a metal body 200 with the antenna component 100 described later. (Refer to...) Figures 2 to 4 The metal body 200 will be described.

[0070] Figure 2 This is a cross-sectional view of the metal card of the present invention. Figures 3 to 7 The diagram illustrates various embodiments of the metal body. Figure 8 This is a cross-sectional view showing the metal body.

[0071] Reference Figures 2 to 8 The metal card of the present invention may include: an antenna component 100, including a primary coil antenna 110 and a secondary coil antenna 120 and a light-emitting part; a shielding sheet 300 formed on the antenna component 100; a metal body 200 that houses the shielding sheet 300 and the antenna component 100; and a card chip 400.

[0072] The metal body 200 is formed of a sheet 210 of metal material, which can accommodate the antenna component 100 and the card chip 400, and can be printed on at least one of the two sides.

[0073] For this purpose, the metal body 200 may include: a receiving opening 210 for receiving a card chip 400; a plurality of penetrating holes 220 for light emitted from a light-emitting device to pass through; and a milled portion 230 for receiving an antenna component 100.

[0074] Multiple through holes 220 can be formed, and the arrangement of the number, spacing, and position of the through holes 220 is shown in the diagram. Figures 3 to 7 This is one example. As mentioned above, the through hole 220 can have various configurations besides the configuration shown in the figure. In this invention, the number and configuration of the through holes 220 are not limited.

[0075] However, for the sake of detailed explanation of the present invention, Figure 5 The metal body 200 shown is the main body for explanation.

[0076] The receiving opening 210 is in an open state so that the chip 400 can be inserted into the metal body 200.

[0077] Multiple through holes 220 are spaced apart from the receiving opening 210, thereby allowing light emitted from the assembled and disposed LED chips 131-134 on the lower side to be transmitted to the outside. The through holes 220 may be filled with a light-transmitting plastic resin to diffuse light or protect the LED chips 131-134.

[0078] The milled portion 230 is machined into a groove facing inward on the opposite side of the metal body 200, thereby forming a space for accommodating the antenna component 100.

[0079] Furthermore, the present invention may include other embodiments.

[0080] For example, such as Figure 9 The metal card shown can omit the shielding material, such as... Figure 10 As shown, the metal body 200 may include a slit 240 extending outward from the receiving opening 210.

[0081] Reference Figure 11 and Figure 12 The antenna component 100 will be described below.

[0082] Figure 11 To show a top view of the antenna component of the present invention, Figure 12 This is a side view of the substrate.

[0083] Reference Figure 11 and Figure 12The antenna component 100 may also include a primary coil antenna 110, a secondary coil antenna 120, a light-emitting part 130, a substrate 140, and a tuning capacitor part 150.

[0084] The substrate 140 serves as a circuit board on which the primary coil antenna 110, the secondary coil antenna 120, and the light-emitting pattern 135 are mounted and / or printed on both sides, and it can be made of a flexible material.

[0085] The primary coil antenna 110 is mounted in a ring on one side of the substrate 140. Its starting point passes through the tuning capacitor section 150 and is connected to the starting point of the secondary coil antenna 120. Its ending point is electrically connected to the starting point of the secondary coil antenna 120.

[0086] The secondary coil antenna 120 is arranged in a ring around the outside of the primary coil antenna 110 (e.g., the outer periphery of the substrate 140).

[0087] The tuning capacitor section 150 is used to compensate for the capacitance of the primary coil and may include: a first terminal C1 (refer to...) Figure 1 ), connected to the primary coil antenna 110; and the second terminal C2 (refer to Figure 1 ), connected to the secondary coil antenna 120.

[0088] The tuning capacitor section 150 may be composed of an MLCC-type chip capacitor or a patterned capacitor composed of an upper conductive pattern and a lower conductive pattern.

[0089] The light-emitting part 130 may include: a plurality of LED chips 131 to 134; light-emitting patterns 135a and 135b to power the LED chips 131 to 134; and board patterns 136a, 136b, 136c and 136d for mounting the LED chips.

[0090] The luminescent patterns 135a and 135b can be formed by one or more ring-shaped coil patterns inside the primary coil antenna 110 and the secondary coil antenna 120. The ring-shaped coil pattern is a separate, independent ring-shaped pattern that has no connection point with the primary coil antenna 110 and the secondary coil antenna 120, and possesses its own antenna pattern (see reference). Figure 1 This allows us to obtain power.

[0091] The light-emitting part 130 may further include: LED chips 131 to 134; and a light diffusion unit (not shown) that surrounds the LED chips 131 to 134 themselves or diffuses the light in the shape of a baffle that stands upright around them, so that the light emitted from the LED chips 131 to 134 can be diffused.

[0092] LED chips 131-134 are mounted on multiple plate patterns 136a-136d formed on the light-emitting patterns 135a and 135b. Furthermore, when current is generated based on the secondary coil antenna 120, the LED chips 131-134 cause the generated current to be input through the light-emitting patterns 135a and 135b and emit light. In this case, the output light can be diffused through a light diffusion unit (not shown) and output to the outside through a penetration hole 220.

[0093] The LED chips 131 to 134 can be located directly below the through-hole 220. That is, the position and number of through-holes 220 are the same as the number and position of the LED chips 131 to 134.

[0094] Therefore, when a user brings their card close to the reader chip 500, the LED chips 131-134 emit light through the current generated from the secondary coil antenna 120. In this case, the LED chips 131-134 transmit light through multiple through holes 220 spaced apart from each other in the metal body 200, allowing the user to identify the light in a point-emitting form.

[0095] Furthermore, the present invention may include a structure in which the light-emitting pattern and the pattern of the coil antenna are connected in a contactless manner, and an embodiment in which the light-emitting pattern and the pattern of the antenna form a contact point.

[0096] Reference Figure 13 and Figure 14 To explain it.

[0097] Figure 13 This is a circuit diagram of another embodiment including a metal card and a card reader. Figure 14 A top view illustrating another embodiment of the antenna component.

[0098] Reference Figure 13 and Figure 14 The light-emitting pattern 136c is connected to the end points of the primary coil antenna 110 and the secondary coil antenna 120 and extends along one direction. The light-emitting pattern may include multiple board patterns 136e on which multiple LED chips are mounted.

[0099] Therefore, the light-emitting pattern 136c can supply power generated from the primary coil antenna 110 and the secondary coil antenna 120 to the LED chips 131-134 mounted on the board pattern 136e.

[0100] The present invention includes the structure described above. Hereinafter, the method for manufacturing a contactless metal card with a light-emitting device according to the present invention will be described.

[0101] Figures 15 to 23 The diagram illustrates each step of the contactless metal card manufacturing method with light-emitting device according to the present invention.

[0102] Reference Figures 15 to 23 An embodiment of the present invention may include: step (a) processing the metal body 200; step (b) processing the shielding sheet 300; step (c) assembling the shielding sheet 300 onto a substrate including a primary coil antenna 110, a secondary coil antenna 120, and a light-emitting part 130; step (d) assembling the antenna component 100 with the shielding sheet 300 assembled thereon with the metal body 200; step (e) forming the through hole 220 and the receiving opening 210 of the metal body 200; step (f) printing on the upper and lower surfaces of the metal body 200; cavity milling step (g); and chip insertion step (h).

[0103] Reference Figure 15 The processing step (a) of the metal body 200 is to process the metal body 200 to form a receiving opening 210, a through hole 220, and a milled portion 230. The receiving opening 210 is processed to a size that can accommodate the card chip 400, and the through hole 220 is formed at the same position as the LED chip.

[0104] Furthermore, the milled portion 230 is machined to form a bezel (not marked) on the outside to accommodate the antenna component 100, so that it is formed on the opposite side of the metal body 200 facing inward.

[0105] Multiple metal bodies 200 can be formed within a single sheet. Therefore, the processing of multiple metal bodies 200 can be performed simultaneously and automatically. The sheet used for mass processing of metal bodies 200 as described above is generally known technology, and therefore its description will be omitted.

[0106] Reference Figure 16 The shielding sheet processing step (b) is a step of processing openings and holes so that the number, position and width of the receiving opening 210 of the metal body 200 are consistent with those of the through hole 220.

[0107] Reference Figure 17 The assembly step (c) of the antenna component 100 is the step of assembling the shielding sheet 300 on the antenna component 100.

[0108] The antenna component 100 is patterned on a flexible substrate 140 and has a primary coil antenna 110, a secondary coil antenna 120, and a tuning capacitor section 150 mounted thereon. Furthermore, light-emitting patterns 135a and 135b are formed on the substrate 140, and multiple LED chips 131 to 134 are mounted on the light-emitting pattern 135a. In this case, the light-emitting pattern section 143 can have light-diffusing units (not shown) centered on each of the LED chips 131 to 134.

[0109] For example, the light diffusion unit (not shown) forms a baffle with the LED chips 131-134 as the center. As another embodiment, it can be a plastic liquid phase resin (e.g., a light-transmitting epoxy resin) that is coated and cured on the upper part of the LED chips 131-134 and diffuses light.

[0110] As described above, the shielding sheet 300 is stacked on the substrate on which multiple LED chips 131 to 134 are mounted, and the multiple LED chips 131 to 134 are exposed to the outside through holes processed in the shielding sheet 300.

[0111] Reference Figure 18 The antenna component 100 and metal body 200 assembly step (d) is the step of assembling the antenna component 100 of the stacked shielding sheet 300 in the milled portion 230 formed on the lower surface of the metal body 200 facing inward.

[0112] Reference Figure 19 The molding step (e) is a molding step in which molding material 610, such as epoxy resin, is injected into the receiving opening 210 and the penetrating hole 220. After molding, a resin layer is formed on the upper and lower surfaces of the metal body 200, thereby performing insulation and protection functions on the upper and lower surfaces of the metal body 200.

[0113] Reference Figure 20 Step (f) of bonding printed sheets 621 and 622 is a step of bonding printed sheets to the upper and lower surfaces of the assembly with the resin layer formed after molding. Printed sheets 621 and 622 can be bonded through a lamination process. Furthermore, printed sheets 621 and 622 can be laminated together with magnetic strip tape or overlay film.

[0114] Alternatively, a printed sheet can be bonded to the upper surface of the metal body, and a DP printing process can be applied to the printed sheet bonded to the upper surface of the metal body.

[0115] Reference Figure 21 The cavity milling step (g) is the step of machining a groove 611 in the molding material 610. The operator processes the molding material 610 to form a groove 611 on the upper end of the molding material 610, thereby machining it into a shape that can assemble the card chip 400.

[0116] Reference Figure 22 and Figure 23 The chip insertion step (h) is the step of assembling the card chip 400 on the upper surface. The card chip 400 is a semiconductor chip mounted on the upper surface of a chip substrate and is disposed in the groove 611 of the molding material 610 in the opposite direction. In this case, the molding material 610 and the card chip 400 can be bonded together using bonding units such as hot melt adhesive film or adhesive film.

[0117] Furthermore, the present invention may include other embodiments, see reference. Figure 24 To explain it.

[0118] Figures 24 to 30 A diagram illustrating a method for manufacturing a metal card according to another embodiment.

[0119] Reference Figures 24 to 30 Another embodiment of the present invention may include: step (a) processing the metal body 200; step (b) assembling an antenna component on a substrate including a primary coil antenna 110, a secondary coil antenna 120 and a light-emitting part 130; step (c) assembling the metal body 200 on the antenna component; step (d) forming the through hole 220 and the receiving opening 210 of the metal body 200; step (e) printing on the upper and lower surfaces of the metal body 200; cavity milling step (f); and chip insertion step (g).

[0120] The processing step (a) of the metal body 200 is to process the metal body 200 to form the receiving opening 210, the through hole 220 and the milled portion 230. The receiving opening 210 is processed to a size that can accommodate the card chip 400, and the through hole 220 is formed at the same position as the LED chip.

[0121] Furthermore, the milled portion 230 is machined to form a bezel (not marked) on the outside to accommodate the antenna component 100, so that it is formed on the opposite side of the metal body 200 facing inward.

[0122] Multiple metal bodies 200 can be formed within a single sheet. Therefore, the processing of multiple metal bodies 200 can be performed simultaneously and automatically. The sheet used for mass processing of metal bodies 200 as described above is generally known technology, and therefore its description will be omitted.

[0123] Assembly step (b) of antenna component 100 is the step of assembling antenna component 100.

[0124] The antenna component 100 is formed by patterning and mounting a primary coil antenna 110, a secondary coil antenna 120, and a tuning capacitor section 150 on a flexible substrate 140. Furthermore, light-emitting patterns 135a and 135b are formed on the substrate 140, and a plurality of LED chips 131 to 134 are formed on the light-emitting pattern 135. In this case, the light-emitting pattern section 143 can provide light-diffusing units (not shown) centered on each of the LED chips 131 to 134.

[0125] For example, the light diffusion unit (not shown) can form a baffle centered on the LED chips 131-134, or, as another embodiment, it can be a plastic liquid phase resin (e.g., a light-transmitting epoxy resin) that is coated and cured on the upper part of the LED chips 131-134 to diffuse light.

[0126] As described above, the shielding sheet 300 is stacked on a substrate on which multiple LED chips 131 to 134 are mounted, and the LED chips 131 to 134 are exposed to the outside through holes processed in the shielding sheet 300.

[0127] The light-emitting component 130 can be connected to the primary coil antenna 110 and the secondary coil antenna 120 by contact or non-contact means.

[0128] The assembly step c of the antenna component 100 and the metal body 200 is the step of assembling the antenna component 100 on which the shielding sheet 300 is stacked in a milled part 230 formed on the lower surface of the metal body 200 facing inward.

[0129] Molding step (d) involves injecting molding material 610, such as epoxy resin, into the receiving opening 210 and the penetrating hole 220 to perform molding. After molding, a resin layer is formed on the upper and lower surfaces of the metal body 200, thereby providing insulation and protection functions on the upper and lower surfaces of the metal body 200.

[0130] The bonding step (e) of printed sheets 621 and 622 is a step of bonding printed sheets to the upper and lower surfaces of the assembly on which the resin layer has been formed after molding. Printed sheets 621 and 622 can be bonded through a lamination process. Furthermore, printed sheets 621 and 622 can be laminated together with magnetic strip tape or overlay film.

[0131] Alternatively, printed sheets 621 and 622 can be bonded to the upper surface of the metal body 200, and DP printing process can be applied to the printed sheets 621 and 622 bonded to the upper surface of the metal body 200.

[0132] Cavity milling step (f) is the step of machining a groove 611 in the molding material 610. The operator processes the molding material 610 to form a groove 611 on the upper end of the molding material 610, thereby machining it into a shape that can assemble the card chip 400.

[0133] The chip insertion step (g) is the step of assembling the card chip 400 on the upper surface. The card chip 400 is a semiconductor chip mounted on the upper surface of a chip substrate and is disposed in the groove 611 of the molding material 610 in the opposite direction. In this case, the molding material 610 and the card chip 400 can be bonded together using bonding units such as hot melt adhesive film or adhesive film.

[0134] The metal cards of one embodiment and another embodiment of the present invention are manufactured through the processes described above. Furthermore, the metal cards of the present invention can include different embodiments depending on their thickness.

[0135] That is, through the process described above, the present invention produces a metal card using materials that are harmless to the human body, and by emitting light to the metal body 200 through point emission, it can provide an aesthetic experience during use.

[0136] Furthermore, the present invention includes yet another embodiment. Hereinafter, yet another embodiment of the present invention will be described.

[0137] Figure 31 This is a circuit diagram of a metal card and a card reader, which are included in yet another embodiment of the present invention.

[0138] Reference Figure 21 In another embodiment of the present invention, the metal card may include: an antenna component 100, assembled with a metal body 200 of metal material, and provided with a primary coil antenna 110, a secondary coil antenna 120 and a light-emitting part 130; and a card chip 400.

[0139] The primary coil antenna 110 can communicate with the card chip 400, and the secondary coil antenna 120 can communicate with the reader chip 500. As described above, the primary coil antenna 110 and the secondary coil antenna 120 are arranged in a ring around the antenna component.

[0140] The starting point S1 of the primary coil antenna 110 is connected to the ending point E2 of the secondary coil antenna 120, and the ending point E1 of the primary coil antenna 110 can be electrically connected to the starting point S2 of the secondary coil antenna 120.

[0141] The structure described above can be used with the antenna component 100 described later (see reference). Figure 16 The assembly of the metal body 200 is achieved. (Refer to...) Figure 14 and Figure 15 The metal body 200 will be described.

[0142] Figure 32 To illustrate a top view of the metal body according to yet another embodiment of the present invention, Figure 33 This is a side view of the metal body. Figure 34 Main view.

[0143] Reference Figures 32 to 34 The metal body 200 is formed of a sheet of metal material 200, which can accommodate the antenna component 100 and the card chip 400, and can be printed on at least one of the two sides.

[0144] Therefore, the metal body 200 may include: a receiving opening 210 for receiving a card chip 400; and a transmission opening 250, which is opened to allow light to pass through the light-emitting portion 130 (see reference). Figure 16 The light emitted is transmitted; the milled portion 230 is machined to house the antenna component 100; and the slit portion 240 extends along one direction on one side of the milled portion 230.

[0145] The receiving opening 210 is opened so that the card chip 400 can be received on one side. The receiving opening 210 can be formed on the opposite side in the area milled by the milling part 230.

[0146] The slit 240 is cut open to extend from the receiving opening 210 along the outer side of the metal body 200. When the antenna induces a current, the slit 240 generates a power supply effect.

[0147] The transmission opening 250 is cut into a predetermined shape or form at a position spaced apart from the receiving opening 210 to form a cut space so that light emitted from the light-emitting part 130 assembled and disposed on the lower side can be transmitted. The transmission opening 250 may be filled with a light-transmitting plastic resin for light diffusion or for protecting the LED 131.

[0148] The milled portion 230 is machined into an inwardly facing groove on the opposite side of the metal body 200, thereby forming a space for accommodating the antenna portion. More specifically, the milled portion 230 may include: an antenna receiving groove 231, formed on one side facing inward to accommodate an antenna pattern; a light-emitting receiving groove 233, formed on the opposite side in an inwardly facing groove shape to accommodate the light-emitting portion 130; and an extension groove 232, extending inward and formed between the antenna receiving groove 231 and the light-emitting receiving groove 233.

[0149] Antenna receiving slot 231 is formed on the opposite side of the metal body 200, facing inward. In this case, antenna receiving slot 231 can be formed over the entire area including receiving opening 210.

[0150] The light-emitting receiving slot 233, which is a slot formed inward at a position spaced apart from the antenna receiving slot 231, can be formed as a region including the transmission opening 250.

[0151] As shown in the figure, the antenna receiving slot 231 and the light-emitting receiving slot 233 can be formed in positions spaced apart from each other, or they can be arranged in adjacent positions. That is, the positions or distances between the antenna receiving slot 231 and the light-emitting receiving slot 233 are not limiting factors and can be modified through various embodiments.

[0152] The extension slot 232 is an inwardly formed slot extending between the antenna receiving slot 231 and the light-emitting receiving slot 233, which houses the antenna component 100 described later.

[0153] Reference Figure 35 An antenna component 100 of another embodiment will be described.

[0154] Figure 35 To illustrate a top view of an antenna component according to yet another embodiment, Figure 36 This is the side view (b).

[0155] Reference Figure 35 and Figure 36 The antenna component 100 may also include an antenna substrate 140 and a tuning capacitor section 150. The antenna substrate 140 is formed with a support pattern, so that the primary coil antenna 110, the secondary coil antenna 120, and the light-emitting section 130 can be electrically connected.

[0156] The antenna substrate 140 may include: an antenna pattern portion 141 having an area that can be received in an antenna receiving slot 231; a light-emitting pattern portion 143 having a light-emitting portion 130 disposed thereon; and an extended pattern portion 142 extending between the antenna pattern portion 141 and the light-emitting pattern portion 143. Preferably, the antenna pattern portion 141, the light-emitting pattern portion 143, and the extended pattern portion 142 are formed as a single unit.

[0157] Furthermore, the antenna pattern section 141, the light-emitting pattern section 143, and the extended pattern section 142 include circuit patterns that can input and output electrical signals.

[0158] The primary coil antenna 110 is mounted in a ring on the antenna pattern section 141. Its starting point is connected to the starting point of the secondary coil antenna 120 via the tuning capacitor section 150, and its ending point can be electrically connected to the starting point of the secondary coil antenna 120.

[0159] The secondary coil antenna 120 is arranged in a ring around the outside of the primary coil antenna 110 (e.g., the outer periphery of the antenna substrate 140).

[0160] The tuning capacitor section 150 is used to compensate for the capacitance of the primary coil and may include: a first terminal C1 connected to the primary coil antenna 110; and a second terminal C2 connected to the secondary coil antenna 120.

[0161] The tuning capacitor section 150 may be an MLCC-type chip capacitor or a patterned capacitor composed of an upper conductive pattern and a lower conductive pattern.

[0162] The light-emitting pattern section 143 is equipped with a plurality of LED chips 131 and has a pattern extending from the extended pattern section 142 to transmit electrical signals to the LED chips 131.

[0163] The light-emitting part 130 may include: an LED chip 131; and a light diffusion unit 136, which surrounds the LED chip 131 itself or diffuses light in the shape of a baffle that stands upright around it, so that the light emitted from the LED chip 131 can be diffused.

[0164] When current is generated through the secondary coil antenna 120, the LED chip 131 will be energized and output light. In this case, the output light can be diffused through the light diffusion unit 136 and output to the outside through the transmission opening 250.

[0165] Therefore, when a user brings their card close to the card reader, the LED chip 131 will light up through the generated current as the secondary coil antenna 120 communicates with the card reader, which can confirm whether there is communication between the card reader and the card chip 400.

[0166] Furthermore, during the series of operations performed by the user as described above, the metal card outputs light through the LED chip 131, which can bring an aesthetic experience to the viewer.

[0167] Another embodiment of the present invention includes the structure described above. Hereinafter, the manufacturing method of another embodiment will be described.

[0168] Figures 37 to 46 The diagram illustrates each step of a manufacturing method according to another embodiment of the present invention.

[0169] Reference Figures 37 to 46 An embodiment of the present invention may include: step (a) processing the metal body 200; step (b) fabricating an antenna component 100 including a primary coil antenna 110, a secondary coil antenna 120, and a light-emitting part 130; step (c) assembling the antenna component 100 onto the metal body 200; step (d) forming an opening in the metal body 200; step (e) bonding a printed sheet 330; a punching step (f); a C-Cut step (g); step (h) printing on the upper surface of the metal body 200; a cavity milling step (i); and a chip insertion step (j).

[0170] Reference Figure 37 The processing step (a) of the metal body 200 is to process the metal body 200 to form the receiving opening 210, the transmission opening 250, the slit portion 240 and the milling portion 230. Among them, the slit portion 240 is cut from one side wall of the metal body 200 and extends to the receiving opening 210.

[0171] Furthermore, the milling portion 230 is machined to include: an antenna receiving groove 231, which faces inward on the opposite side of the metal body 200 and receives an antenna pattern; a light-emitting receiving groove 233, which faces inward to receive a light-emitting portion 1130 on the opposite side; and an extension groove 232, which extends inward and is formed between the antenna receiving groove 231 and the light-emitting receiving groove 233.

[0172] The metal bodies 200 can be formed into multiple shapes within a single sheet. Therefore, the processing of multiple metal bodies 200 can be performed simultaneously and automatically. The sheet used for mass processing the metal bodies 200 as described above is generally known technology, and therefore its description will be omitted.

[0173] Reference Figure 38In step b of manufacturing the antenna component 100, a primary coil antenna 110, a secondary coil antenna 120, and a tuning capacitor section 150 are mounted on the antenna pattern section 141 of the antenna substrate 140, which has a circuit pattern, as a flexible material. Furthermore, a plurality of LED chips 131 are mounted on the light-emitting pattern section 143 of the antenna substrate 140. In this case, the light-emitting pattern section 143 can have a light-diffusing unit 136 centered on each LED chip 131.

[0174] The light diffusion unit 136 can be made of a material capable of diffusing light and form a baffle with the LED chip 131 at the center. Alternatively, as another embodiment, it can be a plastic liquid phase resin (e.g., a light-transmitting epoxy resin) that is coated or cured on the upper part of the LED chip 131 to diffuse light.

[0175] Meanwhile, the antenna substrate 140 is a flexible PCB made of flexible material, and multiple antenna substrates can be grouped and arranged on a single sheet.

[0176] Reference Figure 39 For example, antenna component 100 assembly step (c) is a step of assembling the component inwardly on the milled portion 230 formed on the lower surface of the metal body 200, with reference to the accompanying drawings. In this step, the antenna pattern portion 141, which mounts the primary coil antenna 110, the secondary coil antenna 120, and the tuning capacitor portion 150, is assembled into the antenna receiving groove 231 of the milled portion 230. The extended pattern portion 142 is assembled to match the extended groove 232, and the light-emitting pattern portion 143 is assembled to match the light-emitting receiving groove 233.

[0177] Reference Figure 40 The molding step (d) involves injecting molding material 310, such as epoxy resin, into the receiving opening 210 and the transmission opening 250 to perform molding. After molding, a resin layer 320 is formed on the upper and lower surfaces of the metal body 200, thereby enabling insulation and protection functions on the upper and lower surfaces of the metal body 200.

[0178] Reference Figure 41 Step (e) of bonding the printed sheet 330 is a step of bonding the printed sheet 330 to the upper and lower surfaces of the metal body 200 on which the resin layer 320 is formed after molding. The printed sheet 330 can be bonded through a lamination process. Furthermore, the printed sheet 330 can be laminated together with magnetic stripe tape or film.

[0179] Reference Figure 42 The punching step (f) is a step of separating multiple metal bodies 200 formed in a sheet by punching holes.

[0180] Reference Figure 43The C-Cut step (g) is a step performed after punching to C-Cut the cut surfaces of multiple metal bodies 200 separated from a sheet. C-Cut machining is generally a well-known technique, so its description will be omitted.

[0181] Reference Figure 44 The printing step (h) is a step of printing on the resin layer 320 on the metal side (e.g., DP printing).

[0182] Figure 45 The cavity milling step (i) is the step of machining a groove 311 in the molding material 310. The operator processes the molding material 310 and the resin layer 320 on the upper surface to form a groove 311 on the upper end of the molding material 310 and machine it into the shape of the assembled card chip 400.

[0183] Reference Figure 46 The chip insertion step (j) is the step of assembling the card chip 400 on the upper surface of the molding material 310. The card chip 400 is a semiconductor chip mounted on the upper surface of a chip substrate and is disposed in the groove 311 of the molding material 310 in the opposite direction. In this case, the molding material 310 and the card chip 400 can be bonded together using bonding units such as hot melt adhesive film or adhesive film.

[0218] Reference Figure 17An embodiment of the present invention may include: step (a) processing the metal body 200; step (b) fabricating an antenna component 100 including a primary coil antenna 110, a secondary coil antenna 120, and a light-emitting part 130; step (c) assembling the antenna component 100 onto the metal body 200; step (d) forming an opening in the metal body 200; a printed circuit board 330 bonding step (e); a punching step (f); a C-cut step (g); step (h) printing on the upper surface of the metal body 200; a cavity milling step (i); and a chip insertion step (j).

[0219] The processing step (a) of the metal body 200 is to process the metal body 200 to form the receiving opening 210, the transmission opening 250, the slit 240 and the milling part 230. The slit 240 is cut on one side of the metal body 200 and extends into the receiving opening 210.

[0220] Furthermore, the milled portion 230 includes: an antenna receiving groove 231, which faces inward on the opposite side of the metal body 200 and receives an antenna pattern; a light-emitting receiving groove 233, which is formed inward to receive a light-emitting portion 1130 on the opposite side; and an extension groove 232, which extends inward and is formed between the antenna receiving groove 231 and the light-emitting receiving groove 233.

[0221] Multiple metal bodies 200 can be formed within a single sheet. Therefore, the processing of multiple metal bodies 200 can be performed simultaneously and automatically. The sheet used for mass processing of metal bodies 200 as described above is generally known technology, and therefore its description will be omitted.

[0222] In step (b) of manufacturing the antenna component 100, a primary coil antenna 110, a secondary coil antenna 120, and a tuning capacitor section 150 are mounted on the antenna pattern section 141 of the antenna substrate 140, which is made of a flexible material and has a circuit pattern. Furthermore, a plurality of LED chips 131 are mounted on the light-emitting pattern section 143 of the antenna substrate 140. In this case, light-emitting pattern sections 143 may each have light-diffusing units 136 centered on an LED chip 131.

[0223] The light diffusion unit 136 is made of a light-diffusing material and forms a baffle with the LED chip 131 at the center. Alternatively, as another embodiment, it can be a plastic liquid-phase resin (e.g., a light-transmitting epoxy resin) that is coated and cured on the upper part of the LED chip 131 and can diffuse light.

[0224] Meanwhile, the antenna substrate 140 is a flexible PCB made of flexible material, and multiple antenna substrates can be grouped and arranged on a single sheet.

[0225] The antenna component 100 assembly step (c) is, based on the accompanying drawings, an assembly step performed, for example, on a milled portion 230 formed on the lower surface of the metal body 200 facing inward. Specifically, the antenna pattern portion 141, which mounts the primary coil antenna 110, the secondary coil antenna 120, and the tuning capacitor portion 150, is assembled into the antenna receiving groove 231 of the milled portion 230; the extended pattern portion 142 is assembled to match the extended groove 232; and the light-emitting pattern portion 143 is assembled to match the light-emitting receiving groove 233.

[0226] Molding step (d) involves injecting molding material 310, such as epoxy resin, into the receiving opening 210 and the transmission opening 250 to perform molding. After molding, resin layers 320 are formed on the upper and lower surfaces of the metal body 200, thereby providing insulation and protection functions on the upper and lower surfaces of the metal body 200.

[0227] The printing sheet 330 bonding step (e) is a step in which the printing sheet 330 is bonded to the upper and lower surfaces of the metal body 200 on which the resin layer 320 is formed after molding. The printing sheet 330 can be bonded through a lamination process. Furthermore, the printing sheet 330 can be laminated together with magnetic stripe tape or film.

[0228] The punching step (f) is a step of separating multiple metal bodies 200 formed in a sheet by punching holes.

[0229] The C-Cut step (g) is a step performed after punching to C-Cut the cut surfaces of multiple metal bodies 200 separated from a sheet. C-Cut machining is generally a well-known technique, so its description will be omitted.

[0230] The printing step (h) is the step of printing on the resin layer 320 on the metal side (e.g., DP printing).

[0231] Cavity milling step (i) is the step of machining a groove 311 in the molding material 310. The operator processes the molding material 310 and the resin layer 320 on the upper surface to form a groove 311 on the upper end of the molding material 310 and machine it into the shape of the assembly card chip 400.

[0232] The chip insertion step (j) is the step of assembling the card chip 400 on the upper surface of the molding material 310. The card chip 400 is a semiconductor chip mounted on the upper surface of a chip substrate and is disposed in the groove 311 of the molding material 310 in the opposite direction. In this case, the molding material 310 and the card chip 400 can be bonded together using bonding units such as hot melt adhesive film or adhesive film.

[0233] The metal card of one embodiment of the present invention is manufactured through the processes described above. Furthermore, the metal card of the present invention may include different embodiments depending on its thickness.

[0234] That is, the present invention produces metal cards using materials that are harmless to the human body through the process described above. With light-emitting units in the metal body 200, it can provide an aesthetic appeal during use.

[0235] This invention is not limited to the specific preferred embodiments described herein. Without departing from the spirit of the invention as claimed in the claims, any modifications can be made by those skilled in the art to which this invention pertains, and such modifications should fall within the scope of the claims.
