Description

Technical Field

[0001] This utility model relates to the field of smart card technology, specifically to a smart card with an embroidery effect. Background Technology

[0002] With the development of technology, smart cards have been widely used in various fields, such as financial payments, identity authentication, and membership management. Traditional smart cards are mainly made of PVC material, which is widely used due to its durability, water resistance, and scratch resistance. However, existing smart cards all use flat printed patterns, resulting in poor visual appeal and easy counterfeiting, failing to meet consumers' demands for high quality and personalization. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a smart card with an embroidery effect, which has a better visual performance and is not easy to imitate.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: A smart card with an embroidery effect, comprising, from top to bottom, an upper adhesive film layer, a first embroidery layer, an upper printed substrate layer, an INLAY layer, a lower printed substrate layer, and a lower adhesive film layer. A smart chip is disposed on the INLAY layer, and the smart chip is electrically connected to a coil in the INLAY layer. An embroidery pattern is disposed on the first embroidery layer, and a three-dimensional pattern matching the embroidery pattern is disposed on the upper printed substrate layer. Windows for exposing the contacts of the smart chip are provided on both the upper adhesive film layer and the upper printed substrate layer.

[0005] Compared to existing technologies, the advantages of this invention are as follows: By setting a first embroidery layer and a printing substrate layer with a three-dimensional pattern inside the smart card, the card surface can have a realistic embroidery effect, enhancing the visual appeal of the smart card and meeting consumers' personalized requirements. Simultaneously, by setting anti-counterfeiting layer details within the three-dimensional pattern, the difficulty of counterfeiting the smart card is increased, thereby improving its security and reliability.

[0006] The smart card described above uses a dual-interface chip.

[0007] The smart card described above has a flexible material attached to the surface of the adhesive film layer, and the temperature resistance range of the flexible material is -40 to 230°C.

[0008] In the aforementioned smart card, the compressive strength of the flexible material of the adhesive film layer ranges from 8 to 12.5 MPa.

[0009] In the aforementioned smart card, a second embroidery layer is provided between the lower printed substrate layer and the lower adhesive film, the second embroidery layer is provided with an embroidery pattern, and the lower printed substrate layer is provided with a three-dimensional pattern that matches the embroidery pattern.

[0010] The aforementioned smart card has both the first and second embroidery layers made of 14CT embroidery fabric.

[0011] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0015] 100 Upper adhesive film layer, 200 First embroidery layer, 300 Upper printing substrate layer, 310 3D pattern, 400 INLAY layer, 500 Lower printing substrate layer, 600 Lower adhesive film layer, 700 Smart chip, 800 Second embroidery layer. Detailed Implementation

[0016] The embodiments of this utility model are described in detail below, with reference to Figure 1 This utility model embodiment provides a smart card with an embroidery effect, comprising, from top to bottom, an upper adhesive film layer 100, a first embroidery layer 200, an upper printed substrate layer 300, an inlay layer 400, a lower printed substrate layer 500, and a lower adhesive film layer 600. A smart chip 700 is disposed on the inlay layer 400, and the smart chip 700 is electrically connected to a coil within the inlay layer 400. The first embroidery layer 200 has an embroidery pattern, and the upper printed substrate layer 300 has a three-dimensional pattern 310 matching the embroidery pattern. Both the upper adhesive film layer 100 and the upper printed substrate layer 300 have windows that expose the contacts of the smart chip 700.

[0017] This smart card features an embroidered layer on top of a printed electrode layer with a 3D pattern 310. By adding varying heights to the 3D pattern 310 according to the graphic of the embroidery, the embroidery displays a layered effect that matches its image content. This gives the smart card a visual and tactile experience similar to real embroidery, enhancing its aesthetics and allowing users to express their individuality. Furthermore, anti-counterfeiting details can be incorporated into the layered details of the 3D pattern 310 during manufacturing, increasing the difficulty of counterfeiting and providing more anti-counterfeiting verification methods, thus improving the smart card's security.

[0018] It is understood that the smart card of this utility model embodiment is first fabricated independently for each layer structure, and then the layers are stacked and laminated in sequence. In some embodiments, in order to facilitate the use of the smart card, the smart chip 700 in the smart card is preferably a dual-interface chip, so that the smart card can be read and identified by the terminal in a contact or contactless manner.

[0019] In some embodiments, refer to Figure 2 To further enhance the visual appeal of the smart card, a second embroidery layer 800 can be provided between the lower printed substrate layer 500 and the lower adhesive film layer 600, giving both sides of the smart card a realistic embroidered craft effect. Correspondingly, a three-dimensional pattern 310 matching the embroidery pattern of the second embroidery layer 800 is provided on the lower printed substrate layer 500. It is understood that the layered design of the three-dimensional pattern 310 can be used to highlight the light and shadow variations of the embroidery pattern. For example, a recessed area can be provided in the three-dimensional pattern 310 area corresponding to the shadow area in the embroidery pattern, while a raised area can be provided in the three-dimensional pattern 310 area corresponding to the bright area in the embroidery pattern. This results in slightly recessed shadow areas and slightly raised bright areas in the laminated embroidery pattern, thus enhancing the three-dimensional effect and improving the visual appeal of the smart card. It is understood that the three-dimensional patterns 310 on the upper printed substrate layer 300 and the lower printed substrate layer 500 can be manufactured using laser engraving or high-precision 3D printing.

[0020] The upper adhesive layer 100 and the lower adhesive layer 600 are used to improve the durability of the smart card and the scratch resistance of the pattern. The upper adhesive layer 100 and the lower adhesive layer 600 are preferably made of flexible materials with certain supporting strength and high temperature resistance, such as transparent adhesive pads. In this embodiment, the surfaces of both the upper adhesive layer 100 and the lower adhesive layer 600 are coated with a flexible material with a temperature resistance range preferably from -40 to 230°C, and the compressive strength of the flexible material is preferably in the range of 8 to 12.5 MPa.

[0021] It is understandable that the CT number of the first embroidery layer 200 and the second embroidery layer 800 can be set according to actual needs. In this embodiment, the first embroidery layer 200 and the second embroidery layer 800 should preferably be made of 14CT embroidery fabric, which can provide a good embroidery feel while also showing a relatively delicate embroidery pattern.
