[0014] Furthermore, the insulating layer is made of polyimide insulating film, with grooves reserved at the positions corresponding to the memory chips.

[0015] Furthermore, the thermochromic coating uses reversible thermochromic ink material, and when the ambient temperature exceeds a set threshold (such as 60°C), the color of the thermochromic coating changes significantly.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This environmentally friendly smart card, based on paper, uses environmentally friendly and biodegradable recycled paper as its base layer, reducing environmental pollution at the source. The waterproof and wear-resistant layers significantly improve the smart card's waterproof, moisture-proof, and wear-resistant properties, preventing damage to the card due to environmental factors and extending its service life. The use of environmentally friendly adhesives ensures that the material bonding process is green and pollution-free, in line with the concept of sustainable development.

[0018] 2. This environmentally friendly smart card, based on paper, embeds a storage chip module by creating an installation groove in the paper base layer and fixing it with environmentally friendly adhesive. This ensures that the storage chip and antenna coil are securely installed inside the card, effectively preventing the chip from falling off or being damaged by external forces and guaranteeing the stability of the smart card's information storage and reading functions.

[0019] 3. This environmentally friendly smart card, based on paper, uses a temperature-sensitive color-changing coating to reflect changes in ambient temperature in real time. When the temperature is too high and may affect the chip's performance, the card will alert the user through a color change, increasing the security of the smart card. Underneath the anti-counterfeiting coating, a laser-engraved anti-counterfeiting mark is combined with a scratch-off anti-counterfeiting coating to enhance the smart card's anti-counterfeiting capabilities, prevent counterfeiting and theft, and ensure information security.

[0025] 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.

[0026] Please see Figures 1-4This utility model provides a technical solution: an environmentally friendly smart card based on paper, comprising a smart card body 1, the smart card body 1 including a paper base layer 2, a first waterproof layer 3 disposed at the top of the paper base layer 2, the first waterproof layer 3 being coated on the upper surface of the paper base layer 2, an insulating layer 4 disposed at the top of the paper base layer 2, the insulating layer 4 being coated on the upper surface of the first waterproof layer 3, a first wear-resistant layer 5 disposed at the top of the paper base layer 2, the first wear-resistant layer 5 being coated on the upper surface of the insulating layer 4, a temperature-sensitive color-changing coating 6 disposed at the top of the paper base layer 2, the temperature-sensitive color-changing coating 6 being coated on the upper surface of the first wear-resistant layer 5, a second waterproof layer 7 disposed at the bottom of the paper base layer 2, the second waterproof layer 7 being coated on the lower surface of the paper base layer 2, and a second wear-resistant layer 8 disposed at the bottom of the paper base layer 2, the second wear-resistant layer 8 being coated on the lower surface of the second waterproof layer 7.

[0027] A mounting groove 9 is provided in the middle of the top of the paper base layer 2. An antenna coil 10 is fixedly installed at the bottom of the mounting groove 9. A storage chip 11 is fixedly installed inside the mounting groove 9. The storage chip 11 is electrically connected to the antenna coil 10. A protective hanging ring 12 is fixedly installed at the top of the smart card body 1. The protective hanging ring 12 penetrates the smart card body 1. A marking writing area 13 is fixedly installed at the top of the smart card body 1. An anti-counterfeiting coating 14 is applied to the top of the smart card body 1.

[0028] Working principle: The upper and lower surfaces of the paper base layer 2 of the smart card body 1 are coated with a first waterproof layer 3 and a second waterproof layer 7, respectively, both of which are made of nano-silica waterproof coating. When the smart card comes into contact with water, water molecules cannot penetrate this film, thus effectively preventing water from invading the paper base layer 2. This waterproof layer keeps the paper base layer 2 dry, preventing the paper from softening and deforming due to moisture, thereby protecting the internal storage chip 11, antenna coil 10 and other key components from water corrosion and damage, extending the service life of the smart card. The first wear-resistant layer 5 and the second wear-resistant layer 8 are made of polyurethane wear-resistant coating. Polyurethane material has good wear resistance and flexibility. During the daily use of the smart card, such as when it rubs against other items or is squeezed when placed in a pocket or wallet, the wear-resistant layer can withstand the external friction force, and its wear resistance characteristics can... To effectively prevent the paper surface from being scratched or worn, and to avoid damage to the internal coating or chip due to surface wear, the insulating layer 4 is made of polyimide insulating film, which has excellent electrical insulation properties. Inside the smart card, the storage chip 11 and antenna coil 10 generate weak current and electromagnetic fields when they are working. The insulating layer 4 can effectively isolate these electrical signals from the external environment, preventing external static electricity, electromagnetic interference, and other factors from affecting the normal operation of the storage chip 11 and antenna coil 10. The storage chip 11 communicates wirelessly with the external card reader through the antenna coil 10 to realize the information storage and retrieval functions. When the ambient temperature exceeds 60℃, the color of the temperature-sensitive color-changing coating 6 changes, reminding the user to pay attention to the environment in which the card is located. When it is necessary to verify the authenticity of the card, scratch off the anti-counterfeiting coating 14, and complete the anti-counterfeiting verification by comparing the encoded information with the official database.
