[0002] In the modern context, smart cards, with their embedded chips, enable data storage, encrypted computation, and secure authentication. They are widely used in fields such as financial payments, transportation, identity recognition, and medical and social security, promoting the development of a cashless society and the process of digital management, and becoming an indispensable information carrier and tool in the digital age.

[0003] Existing smart cards mostly utilize built-in systems and algorithms to achieve functions such as data storage, identity authentication, and secure transactions, and are widely used in fields such as financial payments, identity recognition, and communication encryption. However, the internal chips of existing smart cards are placed in the upper right corner of the module. On the one hand, the pin pads of each module and the pin pads of the chip are of uneven length, requiring connecting wires of different lengths during wiring. On the other hand, the wire crossing the chip is relatively long, and it is easy to bump into the chip body during installation, leading to card reading failures. To address the shortcomings of existing technology, this utility model provides a chip-centric smart card to solve the above problems. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] This application provides a chip-centric smart card, which solves the problem that existing smart cards place the internal chip in the upper right corner of the module. On the one hand, the length of the pins of each module and the pin pads 401 of the chip are not uniform, requiring the preparation of connecting wires of different lengths during wiring. On the other hand, the wire crossing the chip is relatively long, which is prone to touching the chip body 4 during installation, causing card reading failures when using the smart card. The solution is to snap-fit ​​the chip body 4 into the center of the lower half 2 of the smart card. This makes the length of the pins of each module to the pin pads 401 of the chip body 4 uniform, eliminating the need to prepare connecting wires of different lengths during installation and speeding up the production efficiency of smart cards. On the other hand, the length of the wire crossing the chip is shortened, avoiding the gold wire touching the chip and effectively improving the reliability of the product. At the same time, a chip removal mechanism 10 is provided in the fixing frame 3, which can quickly disassemble the chip body 4 during maintenance.

[0028] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0029] This utility model discloses a chip-centric smart card.

[0030] Example 1, according to Appendix Figure 1-3 As shown, it includes:

[0031] The upper half 1 of the smart card has a lower half 2 at its bottom. The two together form the overall shell of the smart card, which provides physical protection for the internal chip and module, and prevents external environmental factors (such as dust, moisture, etc.) from damaging the internal components. The lower half 2 of the smart card has a card slot 201 at its bottom to accommodate various functional modules.

[0032] The fixing frame 3 is fixedly connected to the center of the lower half 2 of the smart card. The main function of the fixing frame 3 is to provide a fixed installation position for the chip body 4 and ensure that the chip body 4 is stable in the smart card. At the same time, the slot 301 inside provides a sliding track for the adjustment control buckle 1003 of the chip removal mechanism 10, which facilitates the chip removal operation.

[0033] The chip body 4 is attached to the fixed frame 3. The chip body 4 is the core component of the smart card, responsible for processing and storing data and realizing the various functions of the smart card. The pin pads 401 on it facilitate electrical connection with other modules in the smart card to realize the transmission of data and signals.

[0034] The chip removal mechanism 10 is located within the fixed frame 3 and is used to quickly remove the chip body 4.

[0035] The chip body 4 is provided with pin pads 401, which facilitates connection with other modules in the smart card.

[0036] The lower half 2 of the smart card has a card slot 201, which contains a VCC module 5, an RST module 6, a CLK module 7, a GND module 8, and an I / O module 9.

[0037] VCC module 5 is used to provide operating voltage for chip body 4, RST module 6 is used to initialize or restart chip body 4, and CLK module 7 is used to control the timing of data transmission within chip body 4.

[0038] GND module 8 is used to ensure the stability of signal level, and I / O module 9 is used to realize bidirectional data transmission between chip body 4 and card reader.

[0039] The chip body 4 is installed in the center of the lower half 2 of the smart card. On the one hand, this makes the length from the pin of each module to the pin pad 401 of the chip body 4 uniform, eliminating the need to prepare connecting wires of different lengths during installation and speeding up the production efficiency of smart cards. On the other hand, the length of the wire crossing the chip is shortened, avoiding the gold wire from touching the chip and effectively improving the reliability of the product.

[0040] Example 2, according to Appendix Figure 1-3 As shown, it includes:

[0041] The upper half 1 of the smart card has a lower half 2 at its bottom. The two together form the overall shell of the smart card, which provides physical protection for the internal chip and module, and prevents external environmental factors (such as dust, moisture, etc.) from damaging the internal components. The lower half 2 of the smart card has a card slot 201 at its bottom to accommodate various functional modules.

[0042] The fixing frame 3 is fixedly connected to the center of the lower half 2 of the smart card. The main function of the fixing frame 3 is to provide a fixed installation position for the chip body 4 and ensure that the chip body 4 is stable in the smart card. At the same time, the slot 301 inside provides a sliding track for the adjustment control buckle 1003 of the chip removal mechanism 10, which facilitates the chip removal operation.

[0043] The chip body 4 is attached to the fixed frame 3. The chip body 4 is the core component of the smart card, responsible for processing and storing data and realizing the various functions of the smart card. The pin pads 401 on it facilitate electrical connection with other modules in the smart card to realize the transmission of data and signals.

[0044] The chip removal mechanism 10 is located within the fixed frame 3 and is used to quickly remove the chip body 4.

[0045] The fixed frame 3 is provided with a slot 301.

[0046] The core disassembly mechanism 10 includes:

[0047] The adjusting rod 1001 is slidably connected within the fixed frame 3;

[0048] The shovel plate 1002 is slidably connected within the fixed frame 3, and the shovel plate 1002 is fixedly connected to the adjusting rod 1001.

[0049] An adjustment control buckle 1003 is fixedly connected to the adjustment rod 1001, and the adjustment control buckle 1003 is slidably connected in the slot 301.

[0050] When the card reader cannot read the information in the smart card, it is necessary to open the smart card and test its main internal component, the chip body 4. First, heat the smart card with a heat gun, and then use a tool to pry open the upper half 1 and the lower half 2 of the smart card. If the connection between the pin pads 401 is normal, the chip body 4 needs to be removed for maintenance or replacement through the chip removal mechanism 10. The sliding adjustment control buckle 1003 drives the adjustment rod 1001, which facilitates the movement of the spatula 1002 to squeeze the chip body 4, making it easier to squeeze it out and achieve the purpose of quickly disassembling the chip body 4.
