[0002] With the recent advancement of IT technology and the development and widespread adoption of various electronic payment methods, the use of credit payments based on cards such as credit cards, debit cards, and check cards, as well as app payments, web services, and fintech pay, is rapidly increasing compared to the use of currency.

[0003] In addition, as electronic payment infrastructure expands and new technologies are constantly developed, payment services based on various payment methods, app payments, fintech payments, biometric authentication payments, beacon or wearable payments, cryptocurrency payments using blockchain technology, P2P lending financial payments, electronic wallet payments, NFC, IC chip payments, sensor radar frequency payments, wireless communication payments, electronic coupon payments, integrated transportation payments, integrated passports, etc. are also becoming commonplace.

[0004] To use these payment services, merchants have to bear the fees. Zero Pay was introduced as a government-led standard to alleviate the burden on self-employed business owners caused by the increase in the minimum wage and to unify the payment services that have proliferated in the market. Its use is gradually expanding as it allows self-employed business owners to scan a store's QR code with a camera equipped on a device such as a smartphone and then enter the price, eliminating the need for them to set up a system.

[0005] According to information provided by the Public Data Portal, the number of such QR Pay transactions is increasing significantly every year due to the increase in demand for contactless payments caused by COVID-19 and the expansion of QR code payment infrastructure, and the payment amount is reaching hundreds of billions of won. Rapid growth is expected as demand further increases due to convenience and accessibility.

[0006] However, due to similar QR code designs, there is a problem in that it is difficult to detect forgery caused by double attachment, unauthorized replacement, or the attachment of small QR codes. Additionally, issues regarding damage, durability, and reduced recognition rates due to exposure to ultraviolet rays or contamination in outdoor stores, or in high-humidity environments such as fish markets, have been pointed out as problems that need to be solved.

Specific details for implementing the invention

[0016] The QR code printing plate for electronic payment according to the present invention will be described in detail below with reference to the attached drawings.

[0017] FIG. 1 is an external view according to an embodiment of the present invention, and FIG. 2 is a partial cutaway view according to an embodiment of the present invention, showing the external appearance and structure of a QR code printing plate for electronic payment according to the present invention, and corresponds to a product in a form that can be attached to a structure such as a wall.

[0018] As shown in the attached drawing, the present invention basically comprises a support layer (100) made of an eco-friendly plastic material with a QR code printed on its surface, a security film layer (130) for enhancing security is formed on the upper side of the support layer (100), i.e., the side where the QR code is printed, and a protective layer (200) for enhancing impact resistance is formed on the lower side of the support layer (100).

[0019] In the present invention, an eco-friendly plastic material is applied to product development in accordance with global plastic regulations to form a support layer (100), and the eco-friendly plastic may be selected from high-density polyethylene (HDPE) or recycled PET.

[0020] High-density polyethylene (HDPE) is a non-toxic, eco-friendly plastic in which no endocrine disruptors are detected, and it has excellent stability, durability, and heat resistance, with no endocrine disruptors such as bisphenol, phthalates, or melamine detected at all. Recycled PET (polyethylene terephthalate) is a relatively high-density polyester resin and is a crystalline or amorphous thermoplastic plastic with excellent creep strength, thermal properties such as low water absorption, and excellent dimensional stability.

[0021] In the present invention, after manufacturing a plate-shaped support layer (100) using such an eco-friendly plastic material, a payment QR code is printed on the central printing area (110) using eco-friendly ink, and at this time, it is preferable that the QR code be printed using soybean oil ink or seaweed ink.

[0022] Conventional printers and photocopiers that use oil-based ink consume a lot of power and generate a lot of heat and energy during the printing process, making them equipment with high carbon emissions, and concerns about the environmental problems of oil-based ink are emerging.

[0023] In contrast, plant-based inks are generally more eco-friendly than other oil-based inks and have lower carbon emissions. They are also highly biodegradable, which can reduce carbon emissions during waste disposal. In this invention, vivid and warm colors were achieved by using plant-based inks such as rice oil, soybean oil, seaweed, corn, and coffee grounds. By manufacturing prototypes using this eco-friendly printing method, the working environment at printing sites can be improved and an eco-friendly process can be implemented.

[0024] At this time, the printing of the QR code is performed using a UV printer to dry quickly, and in the experimental example of the present invention, it was confirmed that when printed on recycled PET with soybean oil ink, a clear effect is achieved at an ink output pressure of 45 to 48, and when printed on HDPE with soybean oil ink, a clear effect is achieved at an ink output pressure of 50 to 53.

[0025] In addition, it was confirmed that when printing with seaweed ink on recycled PET, a clear effect was achieved at an ink output pressure of 45–48, and when printing with seaweed ink on HDPE, a clear effect was achieved at an ink output pressure of 50–52. Other substances, such as canella oil, were found to be unsuitable for QR code printing due to bleeding.

[0026] At this time, the printing area (110) on which the QR code is printed may be equipped with an anti-tampering function using a random number code or an anti-tampering function using a special design to prevent forgery. To this end, the technology described in Korean Registered Patent No. 10-2456178 (October 13, 2022) "QR code system having an anti-tampering function using a special design" and Korean Registered Patent No. 10-2456182 (October 13, 2022) "QR code system having an anti-tampering function using a random number code" filed and registered by the applicant may be applied.

[0027] Additionally, a background area (120) is formed around the printing area (110), and various images, text, etc. including payment-related business information can be additionally printed on this background area (120).

[0028] In this invention, to prevent damage to the product due to prolonged exposure to external sunlight, air, moisture, etc., the support layer (100) may further include 0.1 to 2 parts by weight of one or more functional additives selected from the group consisting of a UV stabilizer, an antioxidant, and a flame retardant, with respect to 100 parts by weight of the eco-friendly plastic material.

[0029] The above-mentioned UV stabilizer is added to block or absorb ultraviolet rays, and considering compatibility with other components in the support layer (100), it is preferable that it be a HALS-based material. HALS (Hindered Amine Light Stabilizer) refers to a material used as a light stabilizer in which amine groups are surrounded by a stereochemical structure.

[0030] The above antioxidant is added to prevent deterioration and deformation caused by heat, and specifically may include one or more of phenol-based, amine-based, sulfur-based, and phosphorus-based antioxidants.

[0031] The flame retardant may include one or more selected from the group consisting of magnesium oxide, magnesium hydroxide, aluminum hydroxide, calcium hydroxide, and hydromagnesite (hydromagnesite Mg5(CO3)4(OH)2).

[0032] The above security film layer (130) is a holographic security plastic film and is made of a transparent material so as not to interfere with QR code recognition. It covers and protects the support layer (100), and a hologram (131) having continuity in a set direction is formed. At this time, by appropriately reflecting text or images of the hologram (131), it can be made compatible with products such as promotional materials, and additional information and promotional effects can also be provided.

[0033] The above protective layer (200) is made of a shock-absorbing material and is formed around the lower and side of the support layer to protect the product from damage and impact caused by external forces, and is preferably configured to include waste rubber and a binder.

[0034] The above waste rubber may include one or more selected from the group consisting of waste tires, recycled urethane, and recycled EPDM, and it is advantageous for the waste rubber chips to be crushed to a particle size of 10 mm or less, preferably 1 to 5 mm, more preferably 1 to 3 mm.

[0035] The binder in the protective layer (200) acts to improve durability by improving the phase stability of the protective layer (200) and has excellent tensile strength and elongation characteristics, and may include a polyurethane resin, most preferably it is advantageous to include a polyurethane resin having an isocyanate group content of 10 weight% or less, or 5 to 9 weight%.

[0036] Meanwhile, the protective layer (200) may further include 0.1 to 2 parts by weight of one or more functional additives selected from the group consisting of ultraviolet stabilizers, antioxidants, and flame retardants per 100 parts by weight of the waste rubber, thereby preventing aging or oxidation due to prolonged exposure to sunlight, air, moisture, etc. The specific types of the functional additives are the same as those described above.

[0037] The protective layer (200) according to the present invention may be characterized by being laminated on the lower part of the support layer (100) and having a grid-shaped groove (211) formed therein. Specifically, the protective layer (200) may be configured to include a recess (210) and a protrusion (220) comprising a grid-shaped groove (211) formed to be recessed in a checkerboard shape.

[0038] FIG. 3 is a structural diagram of a protective layer according to an embodiment of the present invention, illustrating a structure of a protective layer (200) in which the recessed portion (210) and the protruding portion (220) are alternately formed.

[0039] As illustrated in FIG. 3(a), the protrusions (220) may be formed alternately with the depressions (210) and configured to have a block shape, and as illustrated in FIG. 3(b), the protrusions (220) may be configured to have a wall shape. Meanwhile, FIG. 3(a) and (b) illustrate the depressions (210) and protrusions (220) being formed alternately and continuously in vertical and horizontal directions, but are not limited thereto. As a non-limiting example, the depressions (210) and protrusions (220) may be formed alternately and continuously in diagonal directions within the protective layer (200), and the depressions (210) and protrusions (220) may be formed irregularly.

[0040] Meanwhile, in order to more effectively mitigate shrinkage and expansion of rubber materials, such as waste rubber, within the protective layer (200) due to the external environment, it is advantageous for the recessed portion (210) and the protruding portion (220), which include the grid-shaped groove (211), to be formed alternately and continuously.

[0041] The groove depth of the grid-shaped groove (211) satisfies 5 to 95%, preferably 20 to 90%, and more preferably 40 to 80% of the thickness of the protective layer (200), thereby allowing the smoothness to be maintained stably for a long time. Meanwhile, if the protective layer (200) has the structure shown in FIG. 3(b), the groove depth of the grid-shaped groove (211) refers to the sum of the upper and lower grid-shaped groove (211) depths based on the bottom portion (212).

[0042] The above protective layer (200) further includes a plurality of permeable holes (not shown) formed to penetrate the grid-shaped groove (211), thereby mitigating the shrinkage and expansion of the protective layer (200) and improving permeability in external environments with large fluctuations in humidity or exposure to rain, or in installation conditions such as fish markets, swimming pools, and bathhouses.

[0043] FIG. 4 is a structural diagram of a border frame according to an embodiment of the present invention, wherein the present invention may further include a border frame (230) formed along the corner perimeter of the support layer (100) and the protection layer (200). In this case, the border frame (230) is formed by welding a plurality of metal pieces (231) vertically to form a rectangular frame, or by bending a metal piece (231) having a length, and the support layer (100) and the protection layer (200) may be configured to have 80 to 99%, preferably 85 to 95%, of the total side surface area.

[0044] This significantly reduces the problem of damage to the edges of the support layer (100) and the protective layer (200), especially due to prolonged use.

[0045] In order to more firmly fix the edge portions of the support layer (100) and the protective layer (200) as described above, the edge frame (230) may have a plurality of fixing grooves (232) formed therein, as shown in FIG. 4. At this time, the shape of the fixing grooves (232) is not particularly limited, but preferably has a "∩" or "∧" shape and may be configured to have two or more formed at regular intervals on each metal piece (231). Meanwhile, FIG. 4 illustrates that three "∩" shaped fixing grooves (232) are formed on each of the metal pieces facing each other, but is not limited thereto.

[0046] The above-described rim frame (230) includes the above-described fixing groove (232), so that the protective layer material is filled into the fixing groove (232) by the compression molding process of the protective layer (200), thereby substantially supporting the protective layer (200) located inside the rim frame (230), and thus the rim frame (230) and the protective layer (200) are more stably fixed.

[0047] Meanwhile, the protective layer (200) according to an embodiment of the present invention can be manufactured through a compression process using a press. In a preferred example, by adding the raw material mixture constituting the protective layer (200) and the aforementioned edge frame (230) into a jig and then compression molding, the edge frame (230) stably holds the entire protective layer (200) inside the protective layer (200), thereby significantly reducing damage to the edge portion.

[0048] It is advantageous for the thickness ratio of the support layer (100) to the protective layer (200) to satisfy 1:2 to 1:6, preferably 1:3 to 1:5, more preferably 1:3.5 to 1:4.5.

[0049] FIG. 5 is a structural diagram according to another embodiment of the present invention, and FIG. 6 is an external view according to yet another embodiment of the present invention.

[0050] As shown in FIG. 5, the protective layer is configured to wrap around the lower side as well as the edge side of the support layer (100) and to form an edge frame (230) around it, thereby sufficiently dispersing external impacts and maximizing cushioning ability.

[0051] Additionally, while it can basically be installed by attaching it to a structure such as a wall, as shown in the attached Fig. 6, it can also be used in a form where the side is folded into a '<' shape while the length of the product is sufficiently long, and then stood upright on a tabletop or similar surface. In this case, even if it falls unintentionally from the position where it was stood, damage to the support layer (100) can be prevented due to the combined structure of the protective layer (200) and the edge frame (230) described above.

[0052] The rights of the present invention are not limited to the embodiments described above but are defined by what is stated in the claims, and it is obvious that a person skilled in the art may make various modifications and adaptations within the scope of the rights described in the claims.
