Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0030] The following is combined with Figures 1-6 This invention describes a portable financial terminal.

[0031] An embodiment of this utility model proposes a portable financial terminal, such as... Figure 1 and Figure 2 As shown, the financial terminal includes a host 100, a main control module 110 and a circuit board 120 connected to the main control module 110. The circuit board 120 has a first surface and a second surface. The circuit board 120 integrates multiple functional modules, including at least two of a keypad module, an identity authentication module, a magnetic card recognition module, a fingerprint recognition module and an IC card recognition module. At least one of the multiple functional modules is arranged on the first surface of the circuit board 120, and the remaining modules are arranged on the second surface of the circuit board 120.

[0032] It is understandable that the host 100 contains a main control module 110 and a circuit board 120 connected to the main control module 110. By integrating multiple functional modules onto the circuit board 120, the internal connection relationship of the device can be simplified, and the stability of the whole machine can be improved. At least one of the multiple functional modules is arranged on the first surface of the circuit board 120, and the remaining modules are arranged on the second surface of the circuit board 120. This double-sided layout makes full use of the space of the circuit board 120, so that more functional modules can be accommodated in a limited plane area, improving space utilization and realizing the miniaturization and thinning of the terminal device for easy portability. This allows it to flexibly adapt to the deployment needs of various scenarios such as temporary service points, community banks, and mobile financial services, without being limited by the large size and fixed installation requirements of traditional financial terminals, thereby improving the flexibility and efficiency of services and further promoting the popularization and convenience of financial services.

[0033] It should be noted that if each functional module is arranged on a separate circuit board 120, multiple circuit boards and corresponding physical connection interfaces are required, which not only increases the complexity of the overall structure but also easily leads to signal interference, poor contact, and assembly failures due to cable redundancy. In contrast, this embodiment integrates multiple functional modules on the same circuit board 120, significantly reducing the number of physical interfaces and internal wiring, effectively suppressing electromagnetic interference, and improving the stability and reliability of system operation. More importantly, this integrated design realizes the fusion of non-cash business functions (such as account opening, transfer, wealth management purchase, customer information modification, loan application, etc.) that were originally distributed across various devices such as self-service terminals, counter business systems, and mobile marketing. Operators only need to log in to a single system to complete all non-cash financial business transactions, breaking the response delay and collaboration barriers caused by traditional multi-system, multi-terminal decentralized control and improving the collaboration efficiency between modules.

[0034] The portable financial terminal provided in this embodiment integrates at least two of the following modules on a circuit board 120: a keypad module, an identity authentication module, a magnetic card recognition module, a fingerprint recognition module, and an IC card recognition module. This integration enables multiple functions, ensuring service security and diversity, and meeting the diverse needs of different users. Furthermore, by arranging at least two functional modules on two surfaces of the circuit board 120, the device has a compact overall structure and is easy to carry. This allows it to flexibly adapt to the deployment needs of various scenarios such as temporary service points, community banks, and mobile financial services, significantly improving the response efficiency of financial services and the user experience.

[0035] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the host 100 is provided with an operation screen 200, which is rotatably connected to the host 100 and is adapted to rotate between a first position and a second position; in the first position, the operation screen 200 covers the host 100; in the second position, there is a preset angle between the plane of the operation screen 200 and the plane of the host 100.

[0036] It is understood that the host 100 is equipped with an operation screen 200, which is rotatably connected to the host 100. This allows the operation screen 200 to fold relative to the host 100 to flexibly change the overall shape of the terminal and is suitable for rotating between a first position and a second position. In the first position, the operation screen 200 covers the host 100, making the terminal a flat whole for easy portability and storage. The operation screen 200 also serves as a cover to protect the internal components of the host 100 from dust and maintain the integrity of the device's appearance. In the second position, there is a preset angle between the plane of the operation screen 200 and the plane of the host 100, so that the operation screen 200 is at the optimal viewing angle for human use, making it easy for users to clearly view the displayed content and perform touch operations.

[0037] It should be noted that in other embodiments, the operation screen 200 can also be connected to the host 100 via a lifting linkage assembly, thereby allowing the operation screen 200 to be lifted and displaced relative to the host 100 and to deflect at an angle to switch the usage state; the operation screen 200 is raised under the support of the lifting linkage assembly and there is a preset angle between its plane and the plane of the host 100, thereby adjusting the operation screen 200 to a height and angle suitable for user operation, so as to improve the user experience.

[0038] Optionally, a positioning component is provided between the operation screen 200 and the host 100. This positioning component supports the operation screen 200, maintaining it at a preset support angle relative to the host 100. It should be noted that the preset angle is the maximum angle the operation screen 200 can rotate relative to the host 100, meaning the operation screen 200 can rotate freely within the range of 0° to the preset angle. The preset support angle is a specific angle within this range, used to achieve stable support for the operation screen 200. For example, the preset angle may be 90°, and the preset support angle may be 30°, 45°, or 60°, etc.

[0039] Furthermore, such as Figure 1 As shown, the positioning component includes a bracket, which is rotatably connected to one of the operation screen 200 and the main unit 100. The other of the operation screen 200 and the main unit 100 is provided with a positioning groove 101 that cooperates with the bracket. When the bracket is engaged in the positioning groove 101, the operation screen 200 is fixed and forms a corresponding preset support angle relative to the main unit 100.

[0040] For example, the operation screen 200 is rotatably mounted on a support, and the main unit 100 is provided with a positioning groove 101 that mates with the support. When the operation screen 200 is in the first position (closed state), the operation screen 200 covers the main unit 100, the support abuts against the back of the operation screen 200, and is stored between the operation screen 200 and the main unit 100. Because the support is relatively thin, it does not increase the overall thickness of the entire machine in the closed state.

[0041] Optionally, the other of the operation screen 200 and the host 100 is provided with multiple positioning slots 101. By locking the bracket into different positioning slots 101, the preset support angle of the operation screen 200 can be adjusted to adapt to the viewing angle requirements in different usage scenarios.

[0042] In this embodiment, the host 100 is provided with four positioning slots 101, corresponding to support angles of 30°, 45°, 60° and 75° respectively. It should be noted that in other embodiments, the number of positioning slots and their corresponding angles can be adjusted according to actual needs.

[0043] In one embodiment of this utility model, multiple functional modules include a keypad module, an identity authentication module, a magnetic card recognition module, a fingerprint recognition module, and an IC card recognition module. The fingerprint recognition module and the IC card recognition module are integrated on the first surface of the circuit board 120, while the keypad module, the identity authentication module, and the magnetic card recognition module are integrated on the second surface of the circuit board 120. By rationally distributing the different functional modules on both sides of the circuit board 120, not only is the internal space layout optimized and the integration improved, but the overall size is also effectively reduced. This allows the terminal to maintain multifunctionality and security while possessing good portability and adaptability, enabling flexible application in various scenarios such as community banks, mobile financial services, and temporary business processing points.

[0044] In one embodiment of this utility model, such as Figure 3 As shown, the host 100 is equipped with a keypad 130 connected to the keypad module, which is used for users to enter transaction passwords or identity information, thereby providing basic input functions and reliable security verification methods for financial operations.

[0045] The host 100 is equipped with a contactless sensing area 140 connected to the identity authentication module. Users can interact in this area using NFC cards or NFC-enabled mobile devices, thereby improving the efficiency and convenience of payment or identity authentication. The contactless sensing area 140 can be specifically implemented as a contactless card reader or an ID card reader. The contactless card reader can be used to identify various recharge cards (such as water, electricity, and gas cards), while the ID card reader is used to read the identity information in the resident ID card to achieve accurate verification of the user's identity.

[0046] The host 100 is equipped with a fingerprint recognition key 150 connected to the fingerprint recognition module. By collecting the biometric information of the operator (such as a bank teller or authorized service personnel) for identity verification, it enables quick login or transaction confirmation without the need to remember a password, simplifies the operation process, and improves the security of the device.

[0047] Furthermore, the keypad 130, the contactless sensing area 140, and the fingerprint recognition key 150 are located on the same side of the host 100 along its length and arranged sequentially along the width of the host 100. This layout design eliminates the need for users to frequently change hand positions or viewing angles during operation, effectively improving operational efficiency and interaction smoothness; at the same time, it also helps optimize the internal structural space of the host 100, facilitating wiring and maintenance.

[0048] Optionally, the host 100 is also provided with a slot-type card slot 170 connected to the identity authentication module for inserting and automatically reading the user's identity document.

[0049] It should be noted that the identity authentication module also has image acquisition and information analysis capabilities. Through the suction card slot 170, it can scan and recognize the text, photos and anti-counterfeiting features on the ID card, and store or upload the relevant information to the system to complete business processes such as real-name authentication and customer information verification. The non-contact sensing area 140 only supports reading the identity identifier or business card information pre-stored in the NFC chip, and does not have the function of optical scanning and data storage of information on the surface of the document.

[0050] In one embodiment of this utility model, the host 100 is provided with an IC card slot 180 connected to an IC card recognition module, enabling the reading and transaction functions of financial IC cards (such as bank cards) with chips, ensuring transaction security. Furthermore, the IC card slot 180 is located on the side edge of the host 100, allowing users to intuitively and quickly locate and insert the card with one hand while holding the device, improving the convenience and smoothness of operation. Simultaneously, placing the slot on the side effectively frees up space on the front of the host 100, allowing for a more rational layout of high-frequency interactive devices such as the keypad 130 and the operation screen 200, optimizing the overall human-computer interaction interface. In addition, when the IC card is inserted, its body is located on the side of the device, preventing obstruction or interference with the user's operation of the front screen and keypad area, ensuring the smooth progress of subsequent transaction steps.

[0051] In one embodiment of this utility model, the host 100 is provided with a magnetic card slot 160 connected to the magnetic card recognition module, thereby providing a physical interface for users to swipe magnetic stripe bank cards or credit cards, and realizing the function of magnetic card financial transactions. Specifically, the magnetic card slot 160 is arranged along one side of the host 100. This integrated design along the side provides users with a clear, unobstructed, and sufficiently long linear card swiping path, enabling users to complete the card swiping action with a smooth and stable gesture when holding the terminal, improving the smoothness of the card swiping operation and the success rate of reading, effectively reducing reading failures caused by hand tremors, uneven card swiping speed, or path deviation, thereby improving user experience and transaction efficiency.

[0052] In one embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 4 As shown, the financial terminal also includes a camera module 300, which is located on the side wall of the host 100. This allows the camera module 300's field of view to cover the user's face when operating the device, facilitating facial recognition for identity verification. Users do not need to adjust their posture or device angle, improving the smoothness and convenience of the transaction process. Furthermore, the camera module 300 has high-definition image capture capabilities, which can be used to photograph and store transaction documents such as ID cards and bank cards when necessary, or to record the operating environment in real time, thereby enhancing the security and traceability of financial services.

[0053] In one embodiment of this utility model, the financial terminal further includes an AI intelligent voice module for realizing human-computer voice interaction. This module supports functions such as voice prompts, operation guidance, business consultation, and command recognition. Users can complete some financial operations or obtain service information through natural language, facilitating operation for elderly users or visually impaired individuals. Simultaneously, the AI ​​intelligent voice module can also be linked with identity authentication, transaction processes, and other aspects to provide real-time security reminders and operation confirmations, further enhancing the intelligence level of the service, the convenience of interaction, and the user experience.

[0054] Optionally, the financial terminal also includes a power module to provide stable and reliable power to all functional modules of the device (including the main control module 110, keypad module, fingerprint recognition module, identity authentication module, IC card recognition module, AI intelligent voice module, etc.). The power module supports multiple power supply methods, such as built-in rechargeable battery, external DC adapter, or power supply through a universal interface such as USB-C, meeting the needs of long-term operation in fixed locations as well as ensuring continuous power supply in mobile or temporary service scenarios.

[0055] In this embodiment, as Figure 1 and Figure 2 As shown, a base 400 is provided below the main unit 100, and the AI ​​intelligent voice module and power module are integrated into the base 400.

[0056] In one embodiment of this utility model, such as Figure 5 As shown, the first surface of the circuit board 120 is the front, and the second surface is the back. The front of the circuit board 120 is provided with a fingerprint recognition interface 121, a camera interface 122 and an IC card interface 124. The fingerprint recognition interface 121 is connected to the fingerprint recognition key 150, the camera interface 122 is connected to the camera module 300, and the IC card interface 124 is connected to the IC card slot 180.

[0057] like Figure 6As shown, the back of the circuit board 120 is provided with a magnetic card interface 125, a password keypad interface 123, an identity authentication interface 126, and a main control interface 127. The magnetic card interface 125 is connected to the magnetic card slot 160, the password keypad interface 123 is connected to the password keypad 130, the identity authentication interface 126 is connected to the non-contact sensing area 140 and the card slot 170 respectively, and the main control interface 127 is connected to the main control module 110.

[0058] In one embodiment of this utility model, the circuit board 120 and the main control module 110 are connected by a flexible flat cable. The flexible flat cable can be bent or folded according to the actual layout of the internal components of the host 100, thereby effectively bypassing obstacles and greatly improving the freedom of wiring design, making it possible to connect in complex and compact spaces. At the same time, by utilizing the thin and light physical characteristics of the flexible flat cable, the stacking height occupied by the connection structure in the vertical direction can be significantly reduced, reserving more valuable space for the arrangement of other functional modules, thereby reducing the overall thickness of the device. In addition, the flexibility of the flexible flat cable allows it to buffer stress through its own deformation when facing internal vibrations caused by carrying or operating the device, thereby reducing the risk of failure of the connection point due to rigid stress concentration and improving the long-term reliability of the connection.

[0059] It should be noted that this embodiment integrates multiple functional modules onto the same circuit board 120, significantly reducing the number of physical interfaces and internal wiring. The portable financial terminal in this embodiment is 403mm long, 238mm wide, 21.5mm high, and weighs 2.4kg, effectively achieving multi-scenario adaptation for bank branches.

[0060] In one embodiment of this utility model, the circuit board 120 also integrates an anti-disassembly monitoring circuit. The conductive loop of the anti-disassembly monitoring circuit is arranged around the keypad module and the IC card recognition module. When the host 100 casing is detected to be illegally opened, the main control module 110 is triggered to execute a data clearing or locking command.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
