[0025] The protective film 4 is made of thermoplastic polyurethane sheet. This material has many excellent properties. It has excellent flexibility and can bend with the smart card 1 when it is bent without breaking, thus ensuring continuous protection of the chip 10. At the same time, it also has good wear resistance, which can reduce the damage to the chip 10 caused by friction in daily use. In addition, the thermoplastic polyurethane sheet also has a certain degree of water resistance, which can prevent moisture from penetrating into the chip 10 and extend the service life of the chip 10.

[0026] A protective mesh 9 is provided on the inner side of the soft silicone sheet 5. The protective mesh 9 is embedded inside the soft silicone sheet 5. When the smart card 1 is subjected to external forces such as squeezing or bending, the protective mesh 9 embedded inside the soft silicone sheet 5 can use its own high strength characteristics to diffuse the stress generated by the external force to the surrounding area, so as to avoid stress concentration in a certain area and cause cracks in the soft silicone sheet 5. At the same time, it provides indirect structural support for the internal chip 10, reducing the squeezing damage to the chip 10 caused by excessive deformation of the soft silicone sheet 5.

[0027] The protective net 9 is made of carbon fiber. Carbon fiber is characterized by high strength and low density. The high strength allows the protective net 9 to effectively resist external impacts and tension, protecting the internal structure of the smart card 1 from damage. The low density ensures that the overall weight of the smart card 1 will not increase significantly due to the presence of the protective net 9, keeping the smart card 1 lightweight and easy to use.

[0028] A composite protective layer 7 is provided on the outside of the printed layer 6. The composite protective layer 7 on the outside of the printed layer 6 provides additional protection for the smart card 1. It can prevent the printed layer 6 from being worn or scratched, and ensure that the printed information is clearly visible. At the same time, the composite protective layer 7 may also have functions such as waterproof, dustproof and UV protection, further improving the durability and stability of the smart card 1.

[0029] A soft reinforcing strip 3 is provided around the outer perimeter of the soft silicone sheet 5. The soft reinforcing strip 3 and the soft silicone sheet 5 are integrally formed. This design provides continuous and uniform reinforcement to the edge of the smart card 1. When the smart card 1 is subjected to external force, the soft reinforcing strip 3 can better transmit and disperse the force, avoiding stress concentration at a certain point, thereby protecting the overall structure of the smart card 1, especially the internal chip 10, from damage.

[0030] The working principle and usage process of this utility model are as follows: The smart card 1 adopts a composite structure design, mainly composed of a chip 10, a protective film 4, and a soft silicone sheet 5. The soft silicone sheet 5 has a specially designed groove 8 inside, into which the protective film 4 can be tightly embedded. The chip 10 is further embedded inside the protective film 4. This design allows the chip 10 to be protected by multiple layers of materials. The soft silicone sheet 5 provides basic flexibility and impact resistance for the entire smart card 1, while the protective film 4 provides more direct protection for the chip 10, preventing it from being physically damaged by external factors. The printing layer 6 on the outer side of the soft silicone sheet 5 can be used to print relevant information, such as card number and logo. The through hole 2 in the middle of one side of the smart card 1 can be used for hanging or connecting with other devices, increasing the flexibility of the smart card 1.
