[0024] The present application provides a kind of intelligent card, Figures 1 to 2 The present application provides a kind of intelligent card's specific embodiment.

[0025] As Figure 1 And Figure 2 As shown in the present application, an intelligent card 100 is provided, which includes a card main body 1 and a transparent nano coating structure 2. The card main body 1 includes an intermediate layer 11 and a pattern printing layer 12 arranged on one end surface of the intermediate layer 11. The transparent nano coating structure 2 is arranged on the side of the pattern printing layer 12 away from the intermediate layer 11. The transparent nano coating structure 2 includes a protective layer 21 and a nano wear-resistant coating 22. The nano wear-resistant coating 22 is located between the protective layer 21 and the pattern printing layer 12.

[0026] The utility model discloses a card body 1's pattern printing layer 12 is covered with nanometer wear -resisting coating 22, and the macroscopic scratch such as key or gravel is resisted, and the printed pattern is avoided being scratched, but due to the brittleness of nanometer wear -resisting coating 22 is greater, under the stress effect, easy to produce microcrack, the protection layer 21 is covered with nanometer wear -resisting coating 22, to absorb external impact energy, prevent microcrack and accumulate and cause the brittle fracture of happening, coating failure. Through the nanometer wear -resisting coating 22 and the protection layer 21 that cover the pattern printing layer 12 can prolong the service life of the smart card 100, reduce maintenance cost.

[0027] Specifically, the material of the nanometer wear-resistant coating 22 includes doped nano silicon dioxide or diamond particles, the protection layer 21 can use a self-repairing nano coating, the material of the self-repairing nano coating includes microcapsule silicone, which can be triggered by ultraviolet light / temperature to cause microcapsule rupture, release the prepolymer to repair the fine scratches and maintain the surface light transmittance.

[0028] It should be noted that, in some embodiments, as shown in Figure 1 The pattern printing layer 12 and the transparent nano coating structure 2 are both provided with two, the two pattern printing layers 12 are respectively covered on the two end faces of the intermediate layer 11, and each transparent nano coating structure 2 is arranged on the side of the pattern printing layer 12 away from the intermediate layer 11. When the two sides of the card body 1 are both printed with patterns, the transparent nano coating structure 2 is respectively covered on the two pattern printing layers 12 to protect the patterns on the pattern printing layer 12.

[0029] Further, in some embodiments, as shown in Figure 2 The card body 1 is covered with the transparent nano coating structure 2 around. In this way, the transparent nano coating structure 2 is covered around the card body 1 to avoid the edge of the smart card 100 being worn. Specifically, the transparent nano coating structure 2 at each position encloses a cladding cavity, and the card body 1 is arranged in the cladding cavity.

[0030] Preferably, in some embodiments, as shown in Figure 1 The transparent plastic film 3 is arranged between the pattern printing layer 12 and the transparent nano coating structure 2. In this way, when the smart card 100 is prepared, a preliminary protection can be formed on the pattern printing layer 12 by covering a layer of transparent plastic film 3 on the pattern printing layer 12.

[0031] Because the adhesion of the nanometer wear-resistant coating 22 is poor, the transparent nano coating structure 2 is difficult to adhere to the card body made of plastic material, therefore, in some embodiments, as shown in Figure 2As shown, the transparent nano-coating structure 2 further comprises a high-adhesion nano-coating layer 23, which is arranged between the nano-wear-resistant coating layer 22 and the pattern printing layer 12. In this way, by adding the high-adhesion nano-coating layer 23 between the nano-wear-resistant coating layer 22 and the pattern printing layer 12, the adhesion of the transparent nano-coating structure 2 is improved. Specifically, the material of the high-adhesion nano-coating layer 23 comprises silicone.

[0032] In order to avoid the dust adsorbed on the intermediate layer 11 during card manufacturing, affecting the effect of the printed pattern, in some embodiments, an antistatic layer is arranged between the intermediate layer 11 and the pattern printing layer 12. In this way, by removing static electricity through the antistatic layer, static electricity is prevented from adsorbing dust and affecting the pattern printing effect.

[0033] Further, in some embodiments, a temperature-sensitive color-changing layer is arranged between the intermediate layer 11 and the pattern printing layer 12. The temperature-sensitive color-changing layer changes color with temperature, so that the color of the pattern on the pattern printing layer 12 changes, realizing dynamic color change of the card surface pattern and improving the anti-counterfeiting effect of the smart card 100.

[0034] In order to add a non-contact communication function to the smart card 100, in some embodiments, as shown in Figure 1 As shown, the communication antenna 111 is wound in the intermediate layer 11. Specifically, the communication antenna 111 can be an NFC antenna or an RFID antenna.

[0035] Further, in order to improve the signal transmission performance of the smart card 100, in some embodiments, as shown in Figure 1 As shown, the intermediate layer 11 is embedded with a conductive layer 112, which is coupled with the coil of the communication antenna 111. In this way, the conductive layer 112 can expand the effective radiation area through coupling effect, improve the electromagnetic wave transceiver efficiency, and thus improve the communication distance and data transmission rate. Specifically, the conductive layer 112 is a graphene film, a metal mesh or a nano-silver wire.

[0036] Since the coupling distance between the conductive layer 112 and the communication antenna 111 also affects the signal transmission performance, preferably, in some embodiments, the spacing between the conductive layer 112 and the coil of the communication antenna 111 is d, 0.05mm≤d≤0.1mm. At this time, the conductive layer 112 and the communication antenna 111 are in a tight coupling state, and the signal transmission performance is best.

[0037] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
