[0023] FIG. 2 is a drawing for explaining the laminated structure of a credit card along line AA of FIG. 1.

[0024] Figure 3 is a flowchart showing a method for manufacturing a credit card according to one embodiment of the present invention.

[0025] The advantages and / or features of the present invention, and the methods for achieving them, will become clearer with reference to the embodiments described in detail below together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but may be implemented in various different forms. These embodiments are provided only to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims. Like reference numerals refer to like elements throughout the specification.

[0026] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0027] FIG. 1 is an image drawing showing the front of a credit card according to one embodiment of the present invention, and FIG. 2 is a drawing for explaining the laminated structure of the credit card along line AA of FIG. 1.

[0028] As illustrated here, a credit card (100) according to one embodiment of the present invention may include a metal sheet (110), a primer layer (120), a transparent layer (130), a color layer (140), and a clear layer, and a clear layer (150) may be formed on the transparent layer (130) or the color layer (140) by a spray method to implement a sanding effect.

[0029] In addition, although not illustrated in detail, an inlay sheet (not illustrated) may be provided on the lower portion of the metal sheet (110). Each layer including the metal sheet (110) may be provided with through holes, and the inlay sheet may be provided with a mounting portion (not illustrated), through which a chip pad (not illustrated) equipped with an IC chip (not illustrated) may be mounted.

[0030] In detail, the IC chip can be mounted on the inlay sheet in a contact or non-contact manner, and thus the credit card (100) of the present embodiment can be used for payment, membership verification, point accumulation, etc. However, although the present embodiment has been described as being applied to a credit card (100), it is obvious that it can be applied to a check card, prepaid card, membership card, transportation card, or point card.

[0031] By this configuration, a pattern of sanding effect on the front of the card can be implemented by spraying, which is simpler, more efficient and more accurate than the conventional sanding method.

[0032] When explaining each configuration, first, the metal sheet (110) of the present embodiment can be made of stainless steel (SUS) as shown in FIG. 2. The surface of the metal sheet (110) can be polished using a polishing device or a polishing agent.

[0033] However, in this embodiment, it has been described that stainless steel is used as the metal sheet (110), but it is not limited thereto and it is obvious that it may be prepared from a metal or metal alloy such as titanium, tungsten, or duralumin.

[0034] Meanwhile, the lower primer layer (120) of the present embodiment can be coated on a metal sheet (110) by, for example, a silk screen method, as illustrated in Fig. 2. The lower primer layer (120) can be made of a transparent, semi-matte epoxy material.

[0035] This lower primer layer (120) can be coated on a metal sheet (110) and a drying process can be performed at 80°C for 30 minutes. However, the material, drying temperature, and time of the lower primer layer (120) are not limited thereto.

[0036] The transparent layer (130) of the present embodiment is a lower transparent layer (130) coated on the lower primer layer (120), as illustrated in FIG. 2, and can be coated by a silk screen method or the like.

[0037] Referring to FIG. 2, a color layer (140) or a clear layer (150) can be selectively coated on the transparent layer (130).

[0038] The color layer (140) of the present embodiment can be coated on a selected area on the transparent layer (130), as illustrated in FIG. 2. The color forming the color layer (140) is visible through the clear layer (150) described later, thereby enabling the expression of various designs on the front of the card. For example, patterns or letters can be expressed through a combination of the color layer (140) and the clear layer (150) described later.

[0039] Meanwhile, a clear layer (150) can be coated by spraying on the color layer (140) or on the transparent layer (130) on which the color layer (140) is not formed.

[0040] The clear layer (150) can be expressed as matte or glossy. To this end, the clear layer (150) of the present embodiment includes a matte clear layer (151) expressed as matte and a glossy clear layer (155) expressed as glossy, as illustrated in FIG. 2. The glossy clear layer (155) and the matte clear layer (151) can be selectively coated on the color layer (140).

[0041] Referring to FIG. 2, a glossy clear layer (155) can be locally positioned between matte clear layers (151), and as shown in FIG. 1, a matte area expressed in a different color can be clearly distinguished by the glossy clear layer (155).

[0042] By this configuration, as illustrated in Fig. 1, the front surface of the card (100) can be provided with various patterns. That is, by various combinations of layers, the front surface of the card (100) can be expressed in various colors, and some areas can be expressed as matte and some areas as non-matte.

[0043] As illustrated in FIG. 2, patterns (#1-#4) can be formed depending on the selection of the color layer (140) or the clear layer (150) on the transparent layer (130). The first pattern (#1) of the present embodiment can be formed by stacking the color layer (140) on the transparent layer (130) and stacking the matte clear layer (151) on the color layer (140). This first pattern (#1) can be applied when expressing the basic area of ​​the front surface of the card (100), as shown in the image of FIG. 1.

[0044] The second pattern (#2) can be formed only with the transparent layer (130) without any other layers being laminated on the transparent layer (130), and as shown in the image of Fig. 1, this pattern can be applied when expressing characters, etc. The second pattern (#2) is formed lower than the first pattern (#1) and also lower than the third pattern (#3) described below, and therefore, when a cardholder touches the surface of the card (100), he or she can feel a different texture when touching the second pattern (#2) and when touching the third pattern (#3).

[0045] The third pattern (#3) can be formed by directly laminating a matte clear layer (151) on the transparent layer (130). This third pattern (#3) can be applied when expressing characters symbolizing the card (100) in the central area of ​​the front of the card, as shown in the image of Fig. 1. This third pattern (#3) is formed lower than the first pattern (#1), so that the cardholder can feel a different texture when touching the surface of the card (100) than when touching the first pattern (#1) or the second pattern (#2).

[0046] Meanwhile, the fourth pattern (#4) may be formed by laminating a color layer (140) on a transparent layer (130), and partially laminating a matte clear layer (151) and a glossy clear layer (155) on the color layer (140). In this fourth pattern (#4), since the glossy clear layer (155) is provided, some areas may be expressed as glossy, unlike other patterns in which the matte clear layer (151) is provided.

[0047] Meanwhile, below, a method for manufacturing a credit card (100) having the aforementioned configuration will be described with reference to the drawings.

[0048] Figure 3 is a flowchart showing a method for manufacturing a credit card according to one embodiment of the present invention.

[0049] As illustrated herein, a method for manufacturing a credit card (100) according to one embodiment of the present invention may include a metal sheet preparation step (S100) of preparing a metal sheet (110), a primer layer coating step (S200) of coating a lower primer layer (120) on the metal sheet (110), a transparent layer coating step (S300) of coating a transparent layer (130) thereon, a color layer coating step (S400) of coating a color layer (140) on at least a portion of the transparent layer (130), and a clear layer coating step (S500) of coating a clear layer (150) on the transparent layer (130) or the color layer (140).

[0050] Here, in the clear layer coating step (S500), a sanding effect can be implemented by forming a clear layer (150) by spraying on the transparent layer (130) or the color layer (140).

[0051] Various patterns can be implemented on the front surface of the card (100) by the clear layer coating step (S500). In the clear layer coating step (S500), as described above, if a color layer (140) is coated on the transparent layer (130) and a matte clear layer (151) is coated, a first pattern (#1) is formed, and if only the transparent layer (130) is expressed as is, a second pattern (#2) is formed.

[0052] In addition, when a matte clear layer (151) is coated on a transparent layer (130), a third pattern (#3) is formed, and when a color layer (140) is coated on a transparent layer (130) and a glossy clear layer (155) and a matte clear layer (151) are coated thereon, a fourth pattern (#4) is formed.

[0053] In this way, according to the present embodiment, a pattern of a sanding effect on the front surface of a card (100) can be implemented by a spray method, which is simpler, more efficient, and more accurate than the conventional sanding method.

[0054] While specific embodiments of the present invention have been described so far, it is clear that various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the scope of the claims set forth below, but also by equivalents thereof.
