[0007] Preferably, the smart card has a frosted layer on both sides.
[0008] Preferably, a metal ring is provided on the upper side of the smart card outside the through hole, and the metal ring is fastened to the upper side of the through hole.
[0009] Preferably, a printing / writing area is provided on the outer side of the printing layer.
[0010] Preferably, the protective layer consists of a fireproof layer and an anti-aging layer, wherein the fireproof layer is attached to the outside of the printed layer and the anti-aging layer is attached to the outside of the fireproof layer.
[0011] Preferably, a self-cleaning layer is provided on the outside of the anti-aging layer, and the self-cleaning layer is a nano-silicon coating layer.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. The silicone sheet has good flexibility and elasticity. It is attached to the outside of the coating layer and can use its elasticity to buffer the impact of the outside on the smart card, reduce the damage to the internal chip caused by collision, squeezing and other situations. At the same time, it makes the smart card more flexible and meets the requirements of ultra-thin characteristics.
[0014] 2. The printing and writing area provides users with a space to record information.

[0015] 3. The fireproof layer is attached to the outside of the printed layer. It has good flame retardant properties. When the smart card is exposed to open flame or high temperature environment, it can effectively delay the spread of fire and protect the printed layer and internal chip and other structures from fire damage. The anti-aging layer is attached to the outside of the fireproof layer. It can resist the corrosion of smart card by factors such as ultraviolet rays and oxygen, slow down the aging rate of smart card materials, maintain the physical properties and appearance of the card, and extend the service life of the smart card.
[0016] 4. The self-cleaning layer composed of nano-silicon coating has good hydrophobicity and anti-fouling properties. When the smart card surface is contaminated with dust, stains or water droplets, the stains and water droplets do not easily adhere to the surface and can slide off on their own or be cleaned by simple wiping, keeping the smart card surface clean, reducing the trouble of cleaning and maintenance, and also preventing stains from adhering for a long time and causing corrosion to the card surface.

[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 In this embodiment of the present invention, an ultra-thin smart card includes a smart card 1; the smart card 1 has a through hole 3 at its upper end, and the smart card 1 is composed of a chip 13, a coating layer 8, a silicone sheet 7, a printing layer 6 and a protective layer 5. The coating layer 8 is attached to both sides of the chip 13, the silicone sheet 7 is attached to the outside of the coating layer 8, the printing layer 6 is attached to the outside of the silicone sheet 7, and the protective layer 5 is attached to the outside of the printing layer 6.
[0026] The smart card 1 has frosted layers 2 on both sides. By increasing the surface friction, the frosted layers 2 on both sides of the smart card 1 can effectively prevent the card from slipping out of the hand when the user holds the smart card 1, and improve the stability of the grip. At the same time, the texture of the frosted layers 2 can also reduce scratches caused by mutual friction between cards, protect the integrity of the card surface, and extend the service life of the card.
[0027] A metal ring 4 is provided on the upper side of the smart card 1 outside the through hole 3. The metal ring 4 is fastened to the upper side of the through hole 3. The through hole 3 on the smart card 1 can be used to thread a lanyard, etc., for easy carrying. The metal ring 4 fastens to the upper side of the through hole 3, which can enhance the structural strength around the through hole 3 and prevent the through hole 3 from breaking due to frequent threading or excessive force, thereby extending the service life of the smart card 1.
[0028] A printing and writing area 12 is provided on the outer side of the printing layer 6. The printing and writing area 12 provides users with a space to record information. Users can write down some temporary information or marks in this area. It also makes it easier for manufacturers or related institutions to print more personalized content according to their needs, thereby improving the practicality and information carrying capacity of the smart card 1.
[0029] The protective layer 5 consists of a fire-resistant layer 9 and an anti-aging layer 10. The fire-resistant layer 9 is attached to the outside of the printed layer 6, and the anti-aging layer 10 is attached to the outside of the fire-resistant layer 9. The fire-resistant layer 9 has good flame-retardant properties. When the smart card 1 is exposed to open flames or high-temperature environments, it can effectively delay the spread of fire and protect the printed layer 6 and internal structures such as the chip 13 from fire damage. The anti-aging layer 10 is attached to the outside of the fire-resistant layer 9 and can resist the corrosion of the smart card 1 by factors such as ultraviolet rays and oxygen, slow down the aging rate of the smart card 1 material, maintain the physical properties and appearance of the card, and extend the service life of the smart card 1. A self-cleaning layer 11 is provided on the outside of the anti-aging layer 10. The self-cleaning layer 11 is a nano-silicon coating layer. The self-cleaning layer 11 composed of the nano-silicon coating layer has good hydrophobicity and anti-fouling properties. When the surface of the smart card 1 is contaminated with dust, stains or water droplets, the stains and water droplets are not easy to adhere to the surface and can slide off on their own or be cleaned by simple wiping, keeping the surface of the smart card 1 clean, reducing the trouble of cleaning and maintenance, and also preventing stains from adhering for a long time and causing corrosion to the card surface.
[0030] The working principle and usage process of this utility model are as follows: When the smart card 1 is in use, the chip 13, as the core of the smart card 1, is responsible for storing and processing information, realizing data reading, writing and interaction. The coating layer 8 is tightly attached to both sides of the chip 13, which can form physical protection for the chip 13, isolate external dust, moisture and other external factors, and buffer external impacts to prevent damage to the chip 13. The silicone sheet 7 has good flexibility and elasticity and is attached to the outside of the coating layer 8, which can further enhance the bending resistance of the smart card 1, adapt to the flexibility requirements under the ultra-thin design, and prevent the smart card 1 from being damaged due to bending. The printing layer 6 is used to carry various logos, patterns and information, so that users can easily identify the purpose and related content of the smart card 1. The protective layer 5 covers the outside of the printing layer 6, providing comprehensive protection for the entire smart card 1 and resisting the corrosion of the smart card 1 by the external environment.
