Description

Technical Field

[0001] This utility model relates to the field of smart card technology with WIFI positioning function, specifically to a smart card with WIFI positioning function. Background Technology

[0002] The development of smart card technology has grown alongside the rapid advancements in microelectronics, maturing as it has become an ideal solution for many industries to address traditional problems. It plays an increasingly important role in areas such as financial payments and electronic passports. With the widespread application of smart card chips and the increasing demand for higher security levels, the extraction and storage of fingerprint features within smart card security chips has garnered growing attention. Smart cards are widely used in bank card systems; financial IC cards, also known as chip bank cards, are bank cards that use chips as their medium. Chip cards have a large capacity, storing keys, digital certificates, fingerprints, and other information. Their working principle is similar to a microcomputer, capable of handling multiple functions simultaneously, providing cardholders with the convenience of a single card for multiple uses. Financial IC cards are issued by commercial banks (credit unions) or payment institutions, employing integrated circuit technology and adhering to national financial industry standards. They possess all or some of the financial functions of consumer credit, transfer settlement, and cash deposit and withdrawal, and can also function as financial instruments for other commercial services and social management.

[0003] The existing patent document CN202222411964.8 provides a new type of smart card with positioning function. By installing functional and stabilizing mechanisms, the smart card can have more complete functions during use. Even if the smart card is lost, it can ensure that the user can find it in the shortest possible time by positioning, which greatly enhances the convenience of daily use of the smart card.

[0004] However, existing smart cards have poor external protection and poor stability of their protective positioning structure, which affects the security of smart card use. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] The purpose of this invention is to provide a smart card with WIFI positioning function to solve the problem of poor WIFI performance mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a smart card with WIFI positioning function, comprising a main body and a positioning mechanism, wherein the positioning mechanism is fixedly installed inside the main body, and the main body includes a card body, a coating, and a card sleeve, wherein the coating is fixedly installed on the surface of the card body, and the card sleeve is fixedly installed on the card body;

[0009] The positioning mechanism includes a card slot, a positioning chip, and a positioning antenna. The card slot is fixedly installed on the front surface of the card body, the positioning chip is fixedly installed in the card slot, and the positioning antenna is fixedly installed inside the card body.

[0010] Furthermore, the main body also includes a card slot and a WIFI chip. A card slot is fixedly installed on the central surface of the card body, and the WIFI chip is fixedly installed in the card slot.

[0011] Furthermore, the main body also includes an antenna mesh and an antenna structure. The antenna mesh is fixedly installed inside the card body, the antenna structure is fixedly installed inside the antenna mesh, and a positioning antenna is fixedly installed inside the antenna mesh.

[0012] Furthermore, the main body also includes an observation window and a connection hole. The observation window is fixedly installed on the surface of the sleeve, and the connection hole is fixedly installed at the front end of the sleeve.

[0013] Furthermore, the main body mechanism also includes a signal receiving slot and a signal generating slot, with the signal receiving slot and the signal generating slot fixedly installed on the edge of the card body.

[0014] Furthermore, the main body also includes printed patterns and printed text, with the printed patterns and printed text fixedly installed on the surface of the card body.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. **Precise Positioning Advantages:** Smart cards with Wi-Fi positioning capabilities utilize Wi-Fi signals for location tracking, providing more accurate location information in certain environments compared to traditional methods. In areas with good Wi-Fi coverage, such as indoor spaces, smart cards can determine their location by receiving signal strength from multiple Wi-Fi access points. Through sophisticated positioning algorithms, their positioning accuracy can reach several meters or even more precise ranges, which is invaluable for applications requiring precise location tracking. 2. **Real-Time Location Updates:** Smart cards can acquire and update location information in real time. The positioning chip continuously receives surrounding Wi-Fi signals, and immediately recalculates the location and updates relevant data whenever signal strength or access point information changes. This real-time capability allows monitoring systems to monitor the smart card's dynamic location at any time, promptly detecting anomalies such as personnel deviating from designated work areas or goods being misplaced. 3. **Enhanced Ease of Use and Contactless Operation:** Most smart cards inherently possess contactless communication capabilities, and combined with Wi-Fi positioning, they become even more convenient to use. Users do not need to insert the card into a device or perform complex operations; as long as the smart card is within Wi-Fi signal coverage and close to a card reader or related equipment, positioning and other functions can be achieved. For example, in access control systems, users simply place their smart cards with Wi-Fi positioning capabilities near the card reader to complete identity verification while simultaneously sending their location information to the access control management system, allowing them to quickly enter designated areas. This multi-functional integration of smart cards combines Wi-Fi positioning with other smart card functions. Users only need to carry one card for multiple uses in different scenarios. For instance, in corporate office settings, the smart card can be used for employee attendance tracking, access control verification for office areas, and payments in the company's cafeteria or shops, significantly improving user convenience and efficiency.

[0017] 2. Enhanced Security: Data Encryption and Privacy Protection. Location information and other user data in the smart card are encrypted using advanced encryption algorithms such as Advanced Encryption Standards (AES) during transmission. When the positioning chip sends location information to the smart card's main chip or external devices, the encryption algorithm processes the data, ensuring that only the recipient with the correct key can decrypt and obtain the true location information. This encryption method effectively protects user privacy and prevents location information from being stolen or tampered with during transmission. Simultaneously, the smart card chip itself has certain security mechanisms, such as preventing unauthorized access to storage units and managing data access permissions, further enhancing data security. Identity Verification and Location-Linked Security: The smart card's Wi-Fi positioning function can be tightly integrated with identity verification to improve system security. For example, in high-security locations, identity verification will only be successful when the smart card's location information matches a pre-authorized location range. This prevents unauthorized use of the smart card in other locations, ensuring that only authorized users in legitimate locations can use the smart card's functions, such as accessing sensitive areas and making payments. With its expanding application scope, smart card positioning holds immense potential for indoor use. In indoor environments, traditional positioning technologies are often limited by factors such as signal obstruction, while smart cards with Wi-Fi positioning capabilities can play a significant role. They can be used in hospitals for patient and staff location management, facilitating resource allocation and patient care; in large shopping malls for customer navigation and store traffic generation, improving the shopping experience; and in warehousing and logistics for precise goods location and inventory management, improving logistics efficiency. Furthermore, these smart cards offer broad prospects for integration with the Internet of Things (IoT). For example, in smart home systems, smart cards with Wi-Fi positioning capabilities can serve as key devices for user identification and location awareness. When a user enters their home with the smart card, its location information can be obtained by the smart home hub, automatically adjusting the status of indoor devices such as temperature and lighting, providing personalized services based on the user's location, and achieving intelligent home control and optimized user experience.

[0023] 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.

[0024] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a smart card with WIFI positioning function, including a main body 1 and a positioning mechanism 2. The positioning mechanism 2 is fixedly installed inside the main body 1. The main body 1 includes a card body 101, a coating 102, and a card sleeve 103. The coating 102 is fixedly installed on the surface of the card body 101, and the card sleeve 103 is fixedly installed on the card body 101.

[0025] The positioning mechanism 2 includes a card slot 201, a positioning chip 202, and a positioning antenna 203. The card slot 201 is fixedly installed on the front surface of the card body 101, the positioning chip 202 is fixedly installed in the card slot 201, and the positioning antenna 203 is fixedly installed inside the card body 101.

[0026] Furthermore, the main body 1 also includes a card hole 104 and a WIFI chip 105. A card slot 201 is fixedly installed on the central surface of the card body 101, and the WIFI chip 105 is fixedly installed in the card slot 201.

[0027] Furthermore, the main body 1 also includes an antenna mesh 106 and an antenna structure 107. The antenna mesh 106 is fixedly installed inside the card body 101, the antenna structure 107 is fixedly installed inside the antenna mesh 106, and a positioning antenna 203 is fixedly installed inside the antenna mesh 106.

[0028] Furthermore, the main body 1 also includes an observation window 108 and a connection hole 109. The observation window 108 is fixedly installed on the surface of the sleeve 103, and the connection hole 109 is fixedly installed at the front end of the sleeve 103.

[0029] Furthermore, the main body 1 also includes a signal receiving slot 110 and a signal generating slot 111. The signal receiving slot 110 is fixedly installed on the edge of the card body 101, and the signal generating slot 111 is fixedly installed on the edge of the card body 101.

[0030] Furthermore, the main body 1 also includes a printed pattern 112 and printed text 113. The printed pattern 112 is fixedly installed on the surface of the card body 101, and the printed text 113 is fixedly installed on the surface of the card body 101.

[0031] Working Principle: The card body 101 structure, substrate material and characteristics: The substrate of the smart card's card body 101 is PVC (polyvinyl chloride) or PET (polyethylene terephthalate). PVC material has low cost, good flexibility, and is easy to process and mold. It can withstand a certain degree of bending without damage, allowing the smart card to be conveniently placed in wallets, cardholders, and other containers. PET material has high strength and toughness, better wear resistance than PVC, and good chemical stability, exhibiting good resistance to water, oil, and other substances, effectively preventing card corrosion. The card body 101 is rectangular, with dimensions conforming to international standards, such as the common bank card size of 85.60mm × 53.98mm, and a thickness of approximately 0.76mm.

[0032] A surface coating 102 is applied to the surface of the smart card to protect the printed patterns 112, text, and chips on the card. This coating 102 is a transparent plastic coating, such as a UV-curable coating 102. The UV-curable coating 102 cures rapidly under ultraviolet light, forming a hard, smooth protective film. Its hardness effectively prevents scratches on the card surface, while the smooth surface facilitates cleaning and keeps the card clean. The thickness of the coating 102 ranges from a few micrometers to tens of micrometers; too thick a coating will affect the card's flexibility, while too thin a coating will not provide sufficient protection.

[0033] Chip module structure and chip packaging: Smart cards utilize packaging technology to protect the internal circuitry of their chips. Common packaging types include DIP (Dual In-line Package) and SOP (Small Outline Package). DIP packages have pins extending from both sides of the chip, arranged like a comb. This packaging facilitates chip insertion and removal on the circuit board, making chip installation and replacement easier. SOP packages are surface-mount packages with smaller chip sizes and closer pin spacing. This effectively reduces the space occupied by the chip within the smart card, allowing for thinner and smaller smart cards. The chip package shell is made of plastic, serving to insulate and protect the chip.

[0034] The chip is connected to the antenna or external interface (such as the metal contacts of a contact smart card) on the card body 101 via gold wire or conductive adhesive. Gold wire bonding is a high-precision method that achieves electrical connection by soldering extremely fine gold wires between the chip and the connection point. The diameter of the gold wire is around tens of micrometers, ensuring the stability and reliability of signal transmission. Conductive adhesive bonding uses adhesive containing conductive particles to bond the chip to the connection point, simultaneously achieving electrical conductivity. The advantages of conductive adhesive are relatively simple operation and lower cost, but it is slightly inferior to gold wire bonding in terms of conductivity and connection stability.

[0035] Antenna structure 107: Antenna material and shape. The antenna in a smart card is made of metal materials, such as copper, aluminum, or silver paste. Copper antennas have good conductivity and low cost, making them a commonly used material; aluminum antennas are lightweight and used in applications where weight is a concern; silver paste antennas are formed by printing silver paste onto the card body 101 using a printing process, allowing for the creation of very fine shapes. Antenna shapes are diverse, commonly including coil-shaped or meandering shapes. Coil-shaped antennas can effectively receive and transmit radio frequency signals, and their inductance and capacitance characteristics can be adjusted according to parameters such as the number of turns and diameter of the coil to match different frequencies. Meandering antennas can increase the antenna length within a limited space, improving antenna performance.

[0036] The antenna layout within the card body 101 needs to consider signal transmission efficiency and coupling with the chip. The antenna can be positioned around the chip or distributed along the edge of the card body 101. Positioning it around the chip improves coupling and reduces signal loss. Distributing it along the edge utilizes the edge space while minimizing interference with other internal components such as the printed pattern 112 and signature strip. The antenna can be attached to the card body 101 via adhesive or printing. Adhesive antennas are pre-fabricated and pasted onto a designated location on the card body 101, offering greater flexibility and allowing for adjustment of the antenna's position. Printed antennas, on the other hand, directly print antenna material, such as silver paste, onto the card body 101, providing higher production efficiency and a tighter fit between the antenna and the card body 101.

[0037] The positioning chip 202 is packaged and connected. The positioning chip 202 of a smart card with WIFI positioning function also requires packaging to protect its internal circuitry. Its packaging form is similar to the chip packaging mentioned earlier, employing miniaturized packaging technology to adapt to the space constraints of the smart card. The positioning chip 202 is connected to other components such as the main chip and antenna via gold wire or conductive adhesive. The connection lines need careful design to ensure that the positioning signal can be accurately transmitted to the main chip for processing and to achieve effective communication with the WIFI network.

[0038] The positioning antenna 203 is a dedicated antenna for receiving and transmitting Wi-Fi positioning signals within the positioning module. The material and shape of these antennas are designed according to the requirements of the positioning function and the space constraints of the smart card. For example, a small ceramic antenna or a microstrip antenna printed inside the card body 101 may be used. Ceramic antennas are smaller in size, enabling better signal reception and transmission performance in a smaller space; microstrip antennas can be precisely printed onto the card body 101 and integrated with other components of the card body 101, improving the overall performance of the smart card. The antenna layout within the card body 101 must consider the distance from the positioning chip 202 and the signal transmission path to minimize signal interference and attenuation.

[0039] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
