[0027] Please refer to Figures 1 to 4 This invention proposes a card reader / writer device 100, which includes: a housing 10, the housing 10 having a cavity 11; and a motherboard assembly 20, the motherboard assembly 20 being installed inside the cavity 11. The motherboard assembly 20 includes a board body 21, a reader / writer module (not shown), and a core board 23. The board body 21 has a card slot (not shown), the core board 23 is installed in the card slot and electrically connected to the board body 21, the core board 23 being used to support the operation of an operating system, and the reader / writer module being located on the board body 21 and electrically connected to the board body 21, the reader / writer module being used to read and write card information.

[0028] Specifically, the card reader / writer 100 includes a housing 10 and a motherboard assembly 20. The motherboard assembly 20 is installed inside the cavity 11, and the housing 10 is used to protect and support the motherboard assembly 20.

[0029] The motherboard assembly 20 consists of a board body 21, a read / write module, and a core board 23. The board body 21 is a circuit board used to connect functional modules, etc. The read / write module is embedded on the board body 21 and is used to read or write data on the card. The core board 23 is mounted on the board body 21 through a card slot. The core board 23 is designed to support the operation of the operating system. The core board 23 integrates necessary hardware such as a microcontroller (MCU), memory (RAM), and basic input / output interfaces (I / O). These components together provide the environment required for the operation of the operating system and ensure the normal operation of the system.

[0030] Furthermore, the design and functionality of the core board 23 can be customized to meet the specific needs of different applications.

[0031] The specific method of installing the core board 23 into the slot can be configured according to actual needs. It can be that a row of gold fingers is provided on the edge of the core board 23, and when the core board 23 is inserted into the slot, the gold fingers directly contact the contact pads on the board body 21 to form an electrical connection. Alternatively, pins can be provided on the core board 23, and slots can be provided in the slot for plug-in connection. Specialized connector assemblies, such as mezzanine connectors or stacked connectors, can also be used to achieve the connection between the core board 23 and the base plate. Furthermore, screw holes are designed for fixing the core board 23, ensuring that the core board 23 will not loosen under vibration or movement. The core board 23 can be safely and stably installed on the board body 21 through the slot, ensuring efficient interconnection and functional integration within the electronic device.

[0032] In one embodiment, the core board 23 uses the FETT507 core board 23, manufactured by Feiling Embedded Technology Co., Ltd. This core board 23 is designed for industrial applications and its structure includes: a processor, integrating a T507 quad-core processor with a Cortex-A53 architecture and a clock speed of 1.5GHz. This processor is highly efficient and suitable for handling complex computing tasks; a graphics processing unit (GPU): a built-in G31 GPU supporting graphics acceleration, suitable for image processing; memory, equipped with 2GB DDR3L RAM to ensure smooth system operation and support multitasking; storage, with 8GB eMMC ROM for storing the operating system and user data, providing sufficient storage space; interfaces, providing rich I / O interfaces for connection and expansion with other hardware devices; and an operating temperature range: possessing industrial-grade operating temperature, allowing stable operation over a wide temperature range.

[0033] The card reader / writer 100 of this invention can be applied in the rail transit industry, such as subway turnstiles and recharge terminals. The technical solution of this invention uses a core board 23 mounted on the board body 21. The core board 23 provides computing and networking capabilities, supporting the operation of the operating system, thereby enabling intelligent control and data processing of the card reader / writer 100. In use, the card reader / writer 100 does not need to be connected to an industrial control computer to support system operation, thus broadening its application scope and service targets, and meeting more needs.

[0034] In an embodiment of the present invention, the board body 21 has an upper surface 211 and a lower surface 212, the read / write module includes a read / write body (not shown in the figure), and the core board 23 and the read / write body are both disposed on the lower surface 212 of the board body 21 and are staggered.

[0035] In detail, the read / write body is used to read or write data on the card. The read / write body and the core board 23 are both set on the same side of the board body 21 and staggered. The layout is reasonable, which can reduce the number of layers and wiring complexity of the board body 21, improve maintainability, and since the card read / write device 100 is a small device with limited space, this layout can make more effective use of the limited space and make the device more compact overall.

[0036] In an embodiment of the present invention, the read / write module further includes a SAM card (not shown in the figure), the read / write body is disposed on the lower surface 212 of the board body 21 and electrically connected to the board body 21, and the SAM card is disposed on the upper surface 211 of the board body 21 and electrically connected to the motherboard.

[0037] It is worth noting that the SAM card is located on the upper surface 211 of the board body 21. The SAM card can improve system security by centrally managing keys and executing secure operations, greatly enhancing the security of the entire system and reducing the risk of data leakage and fraud. As an independent module, the SAM card is easy to upgrade and maintain, and can flexibly respond to changes or improvements in security protocols without replacing the entire card reader / writer 100 system. Furthermore, the SAM card is designed to handle high-security tasks, ensuring the stable execution of secure operations without affecting other functions of the card reader / writer 100.

[0038] In one embodiment, the SAM card supports eight SAM cards compliant with the ISO7816 T0 / T1 driver standard, with a supported baud rate of up to 230400bps; the TYPE A / B cards support the SAM card security processing mechanism compliant with the specification; the TYPE C card security processing mechanism supports a proprietary SAM security key system or a direct key storage system.
