[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Traditional cards are mostly made of PVC, PET, or metal substrates. Among them, plastic cards are easily worn and deformed, and cannot withstand high temperatures; metal cards require an additional electromagnetic shielding layer, which affects signal sensitivity. In addition, traditional cards all suffer from insufficient decoration, poor card texture, difficulty in degradation, and poor environmental performance.

[0025] To address the deficiencies and problems of existing technologies, this disclosure provides a jade composite sheet and card, which are described below in conjunction with specific embodiments and appendices. Figure 1 The present invention will be further elaborated and explained.

[0026] This disclosure provides a jade composite sheet, comprising the following structural layers:

[0027] The base film layer 1 can be made of PVC, PET, PC, or TPU; the laser anti-counterfeiting layer 2 is disposed on the upper surface of the base film, including holographic or diffraction grating structures and / or engraved graphics, and can be laminated on the base film layer 1 using a hot-pressing process; the adhesive layer 3 is disposed between the laser anti-counterfeiting layer 2 and the jade layer 4; the jade layer 4 is a natural jade sheet or a composite of jade powder and adhesive, and can be laminated as a whole or locally in a specific area of ​​the card; the printing layer 5 is disposed on the upper surface of the jade layer 4, and can record cardholder information, card number, identification code, etc., and can also be set with holographic or diffraction grating structures and / or engraved graphics for anti-counterfeiting, or can be set with tactile indicators to indicate important information. This disclosure, by setting a jade layer 4 in the sheet, replaces ordinary plastic or metal substrates, thereby enhancing the mechanical strength and anti-interference ability of the sheet, and giving the sheet better texture, decoration, anti-counterfeiting, and environmental protection. In one embodiment, the jade layer can be stacked in one or more layers, and reflective layers, light-curing layers, etc. can be added at any level inside the sheet as needed.

[0028] In one embodiment, the anti-counterfeiting layer includes locally positioned laser areas and / or non-positioning laser areas. The positions of the locally positioned laser areas can correspond to preset marking areas on the surface, used to enhance the card's anti-counterfeiting properties and aesthetics through complex laser design. Simultaneously, the locally positioned lasers visually highlight the preset marking areas on the card surface, which correspond to areas requiring emphasis, such as the card's identification area, magnetic stripe area, contact pad placement area, chip positioning area, and arrow indicator area. Optionally, the non-positioning laser areas employ random holographic stripes, making it difficult for counterfeiters to replicate the pattern positioning relationships.

[0029] In one embodiment, the engraved graphics include microtext or patterns formed in a locally positioned laser area corresponding to the anti-counterfeiting layer. The line width of the anti-counterfeiting microtext can be selected from 10μm to 150μm. The microtext requires a high-magnification magnifying glass or special equipment for identification, making it difficult to counterfeit. At the same time, the graphics are embedded inside the laser field, which does not affect the overall aesthetics, and provides dual anti-counterfeiting verification points, further improving the anti-counterfeiting level of the product.

[0030] In one embodiment, the local laser field is at least one of embossing, mirror finish, frosted finish, cat's eye effect, dynamic light-changing effect, or 3D stereoscopic image. Dynamic light-changing effect in the laser field refers to using special optical structures or materials to make the laser pattern or surface exhibit dynamic changes in color or pattern as the viewing angle changes. This effect is usually achieved using the principles of light interference, diffraction, or reflection. When an observer views the laser pattern from different angles, the color, brightness, or the pattern itself will change significantly, used for anti-counterfeiting and decoration. For example: using micro-nano structures (such as gratings) to diffract and interfere with light, making the light appear different colors at different angles; using the interference effect of light in media with different refractive indices through the superposition of multiple thin films to achieve color changes; using the diffraction characteristics of holograms to make the pattern present different visual effects at different angles; and using nanoscale micro-nano structure design to achieve strong interference and scattering of light, thereby producing dynamic color changes, etc. All of these belong to dynamic light-changing effects and achievable visual effects. Locally positioned laser areas can employ multiple light effects in combination to further improve the card's anti-counterfeiting level and increase the difficulty of counterfeiting.

[0031] In one embodiment, to match smart card application scenarios, the jade composite sheet also includes an embedded chip module. The chip module includes a contactless chip module and / or a contact chip module to adapt to different card reading modes. The chip module is disposed inside the jade composite sheet through a positioning groove opened in the base film layer 1 or the jade layer 4.

[0032] In one embodiment, to position the chip and enhance signal transmission reliability, a conductive adhesive is coated inside the positioning groove, and the chip module is fixed within the positioning groove by the conductive adhesive. The conductive adhesive can be silver paste or anisotropic conductive adhesive, used for high-frequency signal transmission.

[0033] This disclosure provides a card using the jade composite sheet material, which uses natural stone to replace the non-degradable plastic material as the card substrate. On the one hand, it enhances the mechanical strength and anti-interference ability of the sheet material, and on the other hand, it gives the card better texture, decoration, anti-counterfeiting and environmental protection.

[0034] The above provides a detailed description of the jade composite sheet and card provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea and method of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
