Technical Field
[0001] This utility model relates to the field of chip smart card technology, and in particular to a stripe for a contactless large chip smart card. Background Technology
[0002] With the rapid development of technology, smart card technology has been widely applied in many fields, among which contactless large-chip smart cards have stood out due to their convenience and efficiency. The use of contactless large-chip smart cards is becoming increasingly frequent in many scenarios such as transportation, finance, and access control. As a key component of a smart card, the performance and design of the smart card strip directly affect the overall functionality of the smart card. Traditional smart card strips are relatively simple in design, often focusing only on basic chip protection and simple signal transmission functions, making it difficult to meet the stringent requirements of modern diverse scenarios for smart cards in terms of multifunctionality, high security, and ease of operation.
[0003] Existing smart card strips typically consist of a simple plastic casing encasing a chip and antenna. Their mechanical structure is relatively basic, relying primarily on the plastic casing to secure the internal chip and antenna, ensuring basic physical connection and a degree of protection. Technically, they mainly focus on receiving and transmitting radio frequency signals via the antenna for contactless data interaction with the card reader, with less emphasis on expanding and optimizing other functionalities. For example, they lack specific design considerations for card recognition and ease of use, relying solely on printed patterns or colors on the card surface to distinguish different card types. In practical use, especially in low light or when the user is in a hurry, it is difficult to quickly and accurately identify the card.
[0004] Existing technologies have significant shortcomings in terms of the ease of use of smart cards. When users hold cards, the smooth surface makes them prone to slipping, which not only affects operational efficiency but also easily leads to loss or damage. Furthermore, when holding multiple cards simultaneously, it is difficult to quickly distinguish them based on simple visual features, often requiring extra time to review the text or graphic information on the cards, causing considerable inconvenience, especially in time-sensitive scenarios such as public transportation card swiping and fast access control. This inconvenience severely impacts the user experience and overall efficiency of smart cards. Therefore, a contactless large-chip smart card strip is proposed to address these issues. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a strip for a contactless large-chip smart card, aiming to improve the problems of existing technologies that cannot effectively prevent slippage and facilitate quick card recognition.

[0029] 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.
[0030] Reference Figure 1 and Figure 2This utility model provides an embodiment of a contactless large-chip smart card strip, including a strip body 1, which serves as the core of the entire device and is typically made of high-strength and flexible engineering plastic material, such as polycarbonate (PC). Multiple functional areas are carefully designed inside to store and properly protect the internal chip. Positioning holes 2, generally circular or elliptical, are precisely matched to the positioning pins of the smart card assembly equipment. This precise fit effectively positions the strip body 1 during production and use, preventing deviation and ensuring the chip and other components are always in the correct relative positions, guaranteeing the normal operation of the smart card. The positioning holes 2 are located inside the strip body 1 to position it and prevent deviation. A card structure 3 is located inside the strip body 1 to receive signals for the entire device. An identification component is located on the surface of the strip body 1 to identify the card structure 3. The identification component includes a connecting line 4 and protrusions 5. The connecting line 4 is... The connecting wire 4, placed inside the card structure 3, is made of a thin but stable conductive metal wire, such as tin-plated copper wire. One end of the wire is connected to the chip inside the card structure 3, and the other end can be connected to external detection or identification equipment. It acts as a bridge in the process of data transmission and signal feedback. The raised and recessed parts 5 are set on the surface of the card structure 3. The raised and recessed parts 5 can be tiny hemispherical protrusions or prismatic textures, made of wear-resistant rubber material. They not only increase friction when holding the card to prevent slipping and prevent the card from falling due to an overly smooth surface, but also can be set with unique raised and recessed shapes and arrangements according to the function, institution, or application scenario of different cards, so as to facilitate rapid identification in different environments. They also have a certain degree of anti-counterfeiting and can be used as a physical feature to assist in multi-layer identification and protection, further improving the security and practicality of smart cards.
[0031] Specifically, the raised and recessed features 5 on the surface of the smart card play a crucial role in its use. Their unique texture significantly enhances friction, effectively preventing drops due to a smooth surface and greatly improving ease of use. Furthermore, the carefully designed raised and recessed features 5 vary noticeably depending on the specific purpose and application scenario of each card, facilitating rapid differentiation and identification in diverse environments. In addition, these raised and recessed features 5 possess anti-counterfeiting properties, and combined with other identification technologies, they construct a multi-layered security protection system, effectively ensuring the security and reliability of smart card use.
[0032] Reference Figure 3The strip body 1 contains a protective component to protect the card structure 3. This component includes a waterproof layer 8, which serves as the first line of defense and is carefully placed on the surface of the strip body 1. The waterproof layer 8 typically uses advanced polymer materials, such as polyethylene terephthalate (PET) film, whose dense and stable molecular structure effectively prevents water penetration. This film is uniformly coated onto the surface of the strip body 1 using a precise coating process, forming a continuous and seamless waterproof layer 8. Neither moisture and sweat encountered during daily use nor water droplets in humid environments can penetrate this barrier, thus ensuring the internal card structure 3 is protected from corrosion. While the waterproof layer 8 is on the surface of the strip body 1, a wear-resistant layer 9 is located inside. The wear-resistant layer 9 is typically made of a ceramic coating with high hardness and good toughness, or polymethyl methacrylate (PMMA). The ceramic coating, with its high hardness, effectively resists external friction and scratches. PMMA material is not only wear-resistant but also possesses excellent optical transparency, protecting the card structure 3 without affecting the smart card's visual visibility. The wear-resistant layer 9 is tightly bonded to the waterproof layer 8 through a special spraying or bonding process. When the smart card frequently rubs against other items in the wallet or is repeatedly scratched on a card reader, the wear-resistant layer 9 significantly reduces the damage to the smart card surface, greatly extending the smart card's lifespan. The wear-resistant layer 9 is located inside the waterproof layer 8. An electromagnetic shielding layer 7 is located inside the strip body 1. The electromagnetic shielding layer 7 is typically made of metal materials, such as copper or aluminum foil. These metal materials, with their excellent conductivity and magnetic permeability, can effectively reflect and absorb external electromagnetic interference. The electromagnetic shielding layer 7 is located at the bottom of the wear-resistant layer 9. An encrypted anti-counterfeiting layer 10 is located inside the strip body 1. The encrypted anti-counterfeiting layer 10 is constructed using a combination of various advanced technologies and materials. For example, coatings containing special optical materials, such as holographic anti-counterfeiting coatings, can be used. These coatings can display unique optical patterns from different angles, formed through complex optical micro-nano structures that are extremely difficult to replicate. Simultaneously, RFID tags containing encrypted information can be integrated within them. The information stored in these tags can be verified using special reading devices and matches the encryption algorithm of the smart card's internal chip, further enhancing the smart card's anti-counterfeiting performance. The encrypted anti-counterfeiting layer 10 is located at the bottom of the electromagnetic shielding layer 7. An antibacterial layer 6 is located inside the strip body 1, at the bottom of the encrypted anti-counterfeiting layer 10. The antibacterial layer 6 typically uses a nano-silver coating or organic antibacterial agents, such as quaternary ammonium compounds. The nano-silver particles in the nano-silver coating have strong antibacterial properties, inhibiting the growth and reproduction of bacteria, fungi, and other microorganisms by destroying their cell membranes, proteins, and DNA structures. Quaternary ammonium compounds carry a positive charge and can interact with the negative charge on the surface of microorganisms, destroying their cell structure and thus achieving antibacterial effects.In scenarios where multiple people share a smart card, such as library cards or gym memberships, the antibacterial layer 6 can reduce the growth and spread of microorganisms on and inside the smart card, keeping the smart card clean and hygienic, and providing strong protection for the user's health. The antibacterial layer 6 is located at the bottom layer of the strip body 1.
[0033] Specifically, the smart card design fully considers various protection needs. The surface waterproof layer 8 acts as a robust barrier, effectively blocking moisture and water droplets from penetrating the strip body 1 and preventing corrosion of the card structure 3 surface, thus ensuring the card's stability. The internal wear-resistant layer 9 significantly enhances friction protection, keeping the smart card surface intact even in environments prone to scratches, such as wallets. The electromagnetic shielding layer 7 plays a crucial role in complex electromagnetic environments, accurately reflecting and absorbing external electromagnetic interference to maintain smooth and secure communication between the smart card's internal chips. The encrypted anti-counterfeiting layer 10 further enhances user security, greatly reducing the risk of duplication thanks to its unique encryption technology. The innermost antibacterial layer 6 effectively inhibits mold growth, preventing damage to the internal structure caused by microbial growth, comprehensively ensuring the smart card's quality and lifespan.
[0034] Working principle: When the card is used, the raised and recessed surfaces 5 on the surface can prevent it from slipping and falling off due to the smooth surface. Different raised and recessed surfaces 5 can be set according to different cards to facilitate identification in different environments. It can also increase anti-counterfeiting and provide multi-layer identification protection.
[0035] In addition, the waterproof layer 8 on the surface prevents surface moisture or water droplets from entering the strip body 1 and corroding the surface of the card structure 3. Then, the wear-resistant layer 9 inside improves friction protection and prevents scratches and damage to the surface when placed inside a wallet. Then, the electromagnetic shielding layer 7 inside the wear-resistant layer 9 can effectively reflect and absorb external electromagnetic interference to prevent external electromagnetic interference from affecting the communication of the chip inside the smart card. Subsequently, the internal encryption and anti-counterfeiting layer 10 improves user security and prevents duplication. Finally, the innermost antibacterial layer 6 prevents the growth of mold inside and inhibits its growth from causing damage to the inside.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
