Description

Technical Field

[0001] This invention relates to the field of police verification equipment technology, and in particular to a foldable portable identity and document verification device. Background Technology

[0002] In scenarios such as police duty, security for large-scale events, and control at transportation hubs, verification of identity documents and tickets is an important task for security management and risk assessment.

[0003] Currently, most identity verification devices on the market are fixed, all-in-one machines. These devices are large, heavy, and cannot be folded for storage. Once installed, their location is fixed, making them suitable only for verification scenarios at fixed checkpoints and security lanes. They cannot meet the dynamic operational needs of outdoor mobile inspections, temporary checkpoint checks, and mobile on-site verification. Furthermore, traditional verification devices have limited functionality. Some only support facial recognition, while others only support ID card reading. Ticket recognition is often handled by separate devices, making it impossible to achieve simultaneous verification of people, ID cards, and tickets. Multiple devices are required during operation, resulting in cumbersome operation, low verification efficiency, and an inability to adapt to diverse scenarios. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this invention is to provide a foldable portable identity and ticket verification device that can achieve diversified functions and is suitable for use in multiple scenarios.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] A foldable portable identity verification device includes: a shell, a support base, an integrated identity verification system, and a processing and storage system.

[0007] The support base and the housing are connected by a hinge device;

[0008] The integrated identity verification system includes an ID card reading module, a liveness detection module, and a ticket information recognition module. These modules are respectively mounted on the housing. The ID card reading module reads the chip information within the second-generation ID card; the liveness detection module verifies whether the verifier is a real person; and the ticket information recognition module extracts key information from the ticket.

[0009] The processing and storage system is electrically connected to the integrated verification system for identity documents and tickets, the liveness detection module, and the ticket information recognition module, respectively. The processing and storage system is used for logic control and local data storage.

[0010] Furthermore, the foldable portable ID card verification device also includes a clean high-definition capture camera, which is located on the top of the housing. The clean high-definition capture camera is used to continuously capture multi-dimensional features of personnel, and is electrically connected to the processing and storage system.

[0011] Furthermore, the processing and storage system includes a main control unit and a storage unit. The main control unit adopts an ARM architecture multi-core processor and is used to coordinate the work of the ID card reading module, the human face liveness detection module, and the ticket information recognition module and to perform verification comparison and feature analysis. The storage unit is used to store verification records, captured feature images, and associated timestamp video stream data.

[0012] Furthermore, the foldable portable identity verification device also includes a power supply module, which is located in the housing and is electrically connected to the integrated identity verification system and the processing and storage system. The power supply module is used to supply power to the integrated identity verification system and the processing and storage system.

[0013] Furthermore, the power supply module is made of a removable battery pack and has a charging interface.

[0014] Furthermore, the hinge device includes a hinge seat and a hinge shaft. The hinge seat is disposed on the support base, and the hinge shaft is disposed on the housing. The hinge seat and the hinge shaft are connected by a damped hinge.

[0015] Furthermore, the foldable portable ID card verification device also includes a dual-mode communication module and an operation panel. The dual-mode communication module is detachably electrically connected to the processing and storage system and the operation panel, respectively. The dual-mode communication module is used to transmit data information in the processing and storage system to the operation panel. The operation panel has the functions of real-time image viewing and image playback.

[0016] Furthermore, both the housing and the support base are telescopic structures.

[0017] Furthermore, the ID card reading module is made using a contactless IC card reader.

[0018] Furthermore, the human liveness detection module is made using a combination of an infrared camera and a visible light camera.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. The integrated identity verification system includes an ID card reading module, a liveness detection module, and a ticket information recognition module. These modules are respectively mounted on the housing. The ID card reading module reads the chip information from the second-generation ID card; the liveness detection module verifies the identity of the verifier; and the ticket information recognition module extracts key information from the ticket. During operation, the ID card reading module accurately reads the chip information of the second-generation ID card and verifies its authenticity. The liveness detection module identifies the identity of the person being verified and prevents identity theft. The ticket information recognition module extracts various key ticket information and verifies the validity of the ticket, breaking the limitations of traditional verification devices that only support single identity verification or single ticket recognition. Through the integrated design of these three verification functions, a single device can simultaneously perform identity verification, liveness detection for fraud prevention, and ticket verification, achieving diversified device functionality. This eliminates the need for multiple devices to work together, reducing equipment procurement and maintenance costs, simplifying on-site verification processes, and adapting to various scenarios.

[0021] 2. The support base and the housing are connected by a hinged device. During operation, when the equipment is idle and being moved, the support base can be folded to fit the housing, compressing the overall volume of the equipment for easy hand-carrying, storage, and transportation. When the equipment is in operation, the support base can be unfolded and the tilt angle of the housing can be adjusted to accommodate different operating postures such as standing and sitting. It can also be used in various ways, including desktop placement, temporary handheld use, and outdoor placement. Compared to traditional fixed, integrated, and non-foldable verification equipment, this equipment has a flexible structure and high portability, eliminating the limitations of fixed work locations and adapting to the verification needs of different venues such as stations, scenic spots, stadiums, conference centers, and corporate access control systems, thus improving the equipment's scenario adaptability.

[0022] 3. The processing and storage system is electrically connected to the integrated identity and ticket verification system, the facial recognition module, and the ticket information recognition module, respectively. The processing and storage system is used for logic control and local data storage. During operation, the processing and storage system can independently complete the entire logical operation process, including receiving data from multiple modules, comparing identity and ticket information, and determining results, without relying on a cloud network or backend server. Simultaneously, it can completely retain verification data locally, enabling data traceability. Traditional intelligent verification devices often rely on network transmission and cloud computing, making them unusable in scenarios with no network, weak network, or poor outdoor signal. This device, through its local processing and storage design, can achieve 24 / 7 offline verification, perfectly adapting to verification scenarios in various complex network environments, including indoor, outdoor, and remote locations, further expanding the device's applicability.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] See Figures 1-3 A preferred embodiment of the present invention provides a foldable portable identity verification device, comprising a housing 1, a support base 2, an integrated identity verification system 4, and a processing and storage system.

[0031] The support base 2 is connected to the housing 1 via a hinge mechanism, which allows for rotation from 0° to 180°. When the equipment is stored, it is easy to carry and store; when the equipment is in operation, the tilt angle of the housing 1 can be adjusted as needed to accommodate various operating postures such as standing and sitting. The hinge mechanism can be a single-axis or dual-axis symmetrical damping hinge or a silicone damping pivot to suit different operating conditions.

[0032] The integrated identity verification system 4 can be located on the front of the housing 1, comprising a partitioned ID card reading module 41, a liveness detection module 42, and a ticket information recognition module 43. Each module works independently yet collaboratively to achieve automatic integrated verification of people, ID cards, and tickets. The ID card reading module 41 can be embedded in the lower part of the housing 1, quickly reading the chip information of second-generation ID cards and verifying the authenticity of the documents. The liveness detection module 42 can be located in the center of the upper part of the housing 1, capturing facial images around the clock and using a liveness recognition algorithm to resist cheating methods such as photos and masks, preventing identity theft. The ticket information recognition module 43 can be positioned between the two, accurately extracting key information such as the number, validity period, name, ID number, and shift of paper and electronic tickets, adapting to various ticket recognition scenarios.

[0033] The processing and storage system can be built into the housing 1 and electrically connected to the ID card reading module 41, the facial liveness detection module 42, and the ticket information recognition module 43, respectively. With the processing and storage system as the core, it is responsible for the overall logic control and multi-module collaborative scheduling of the device. The processing and storage system can simultaneously compare and verify the identity, facial, and ticket information, automatically determine the verification result, and store the verification record locally. It supports offline verification and data traceability in environments without network or with weak network. It achieves a miniaturized, multi-functional, and portable design, adaptable to verification work in various scenarios such as stations, scenic spots, venues, and conferences. The processing and storage system can be equipped with an operation screen for data traceability.

[0034] This invention provides multiple preferred alternatives to expand the equipment's adaptability: First, the hinge device is equipped with damping, allowing for angle adjustment to adapt to special working conditions and prevent loosening issues after long-term use; second, the document information recognition module 43 can be equipped with an anti-reflective lens and an adaptive supplementary lighting structure to adapt to the recognition of various complex documents.

[0035] Working Principle: This device uses a hinge mechanism to achieve the folding and opening of the support base 2 and the self-adjusting angle of the housing 1. In transport mode, the support base 2 can be completely folded to fit the back of the housing 1, making it portable and easy to carry. In verification operation mode, the support base 2 can be flipped open using the hinge mechanism to fix the housing 1 in a suitable operating position, adapting to the verification needs of different personnel and locations. The housing 1's ID card reading module 41, liveness detection module 42, and ticket information recognition module 43 work together to achieve simultaneous collection and integrated verification of three types of information: person, ID card, and ticket. The ID card reading module 41 reads the identity information stored in the chip inside the second-generation ID card at close range and completes the initial verification of the document's authenticity, quickly completing the identity information entry. The liveness detection module 42 simultaneously collects facial images of the verification personnel and identifies real facial features, accurately identifying counterfeit verification methods such as photos, videos, and simulated masks, preventing fraudulent verification behaviors such as proxy scanning and identity theft, and ensuring the authenticity and validity of the verification subject. The ticket information recognition module 43 performs high-definition acquisition of screen images of paper or electronic tickets, automatically extracting key data such as ticket number, access permissions, validity period, name, ID number, and shift, to quickly identify and determine the validity of the ticket. The processing and storage system is electrically connected to each functional module, receiving ID card information, liveness detection results, and ticket recognition data in real time. Through built-in logic algorithms, it automatically compares and verifies the data of the person, ID, and ticket, determining the consistency of the person and ID, the validity of the ticket, and the compliance of the verification qualifications, and outputs standardized verification results. Simultaneously, the processing and storage system relies on local storage units to locally retain personnel information, ticket data, verification time, and verification results for each verification, achieving fully offline verification and data traceability archiving without relying on an external network environment. Each module operates independently yet in a coordinated sequence. Through the organic combination of a foldable portable mechanical structure and an integrated intelligent verification circuit structure, the device can stably complete fast and traceable integrated verification of persons, ID cards, and tickets in various scenarios such as station ticket checks, scenic area entrances, venue security checks, and conference check-ins.

[0036] Obviously, the integrated identity verification system 4 includes an ID card reading module 41, a liveness detection module 42, and a ticket information recognition module 43. These modules are respectively mounted on the housing 1. The ID card reading module 41 reads the chip information from the second-generation ID card; the liveness detection module 42 detects whether the verifier is a real person; and the ticket information recognition module 43 extracts key information from the ticket. During operation, the ID card reading module 41 accurately reads the chip information of the second-generation ID card and verifies its authenticity; the liveness detection module 42 identifies a real person and prevents identity theft; and the ticket information recognition module 43 extracts various key ticket information and verifies the validity of the ticket. This system overcomes the limitations of traditional verification devices that only support single identity verification or single ticket recognition. Through the integrated design of the three types of verification functions, a single device can simultaneously perform multiple functions such as identity verification, liveness detection and document verification, thereby achieving diversified device functions. It eliminates the need for multiple devices to work together, reduces equipment procurement and maintenance costs, simplifies on-site verification processes, and is suitable for use in multiple scenarios.

[0037] The support base 2 and the housing 1 are connected by a hinge device 3. During operation, when the equipment is idle and being moved, the support base 2 can be folded to fit the housing 1, compressing the overall volume of the equipment for easy hand-carrying, storage, and transportation. When the equipment is in operation, the support base 2 can be opened and the tilt angle of the housing 1 can be adjusted to accommodate different operating postures such as standing and sitting. It can also be used in various ways, such as desktop placement, temporary handheld use, and outdoor placement. Compared with traditional fixed, integrated, and non-foldable verification equipment, this equipment has a flexible structure and high portability, which can break free from the limitations of fixed work locations and adapt to the verification needs of different venues such as stations, scenic spots, venues, conferences, and enterprise access control, thus improving the equipment's scene adaptability.

[0038] The processing and storage system is electrically connected to the integrated identity and ticket verification system 4, the facial liveness detection module 42, and the ticket information recognition module 43, respectively. This system is used for logic control and local data storage. During operation, the processing and storage system can independently complete the entire logical operation process, including receiving data from multiple modules, comparing identity and ticket information, and determining results, without relying on a cloud network or backend server. Simultaneously, it can completely retain verification data locally, enabling data traceability. Traditional intelligent verification devices often rely on network transmission and cloud computing, making them unusable in scenarios with no network, weak network, or poor outdoor signal. This device, through its local processing and storage design, can achieve 24 / 7 offline verification, perfectly adapting to verification scenarios in various complex network environments, including indoor, outdoor, and remote locations, further expanding the device's applicability.

[0039] Preferably, the foldable portable ID verification device further includes a clean high-definition capture camera 5, which is located on the top of the housing 1. The clean high-definition capture camera 5 is used to continuously capture multi-dimensional features of personnel, and is electrically connected to the processing and storage system. Specifically, the clean high-definition capture camera 5 is deployed independently of the verification module on the top of the device, employing a wide-angle, low-distortion lens and supporting 1080P and higher resolution video recording. The camera is automatically triggered when a person approaches the verification area, performing continuous, imperceptible capture, focusing on capturing multi-dimensional features of the person, including: clothing features (such as the style and color of police uniforms, civilian clothes, etc.), personal belongings features (such as glasses, hats, headwear, backpacks, mobile phones, etc.), and physical features (such as hairstyle, beard, whether or not leather shoes are worn, etc.). By adding a clean, high-definition capture camera 5 to the top of the housing 1, the device can form a top-panoramic capture-assisted verification system based on the original fixed-point single-shot face recognition. This system can capture verification personnel from multiple angles and continuously, accurately capturing multi-dimensional facial details and human posture features. It replaces the traditional single-view, single-image recognition method, making up for the limitations of conventional face detection modules in terms of perspective and imaging coverage. It avoids recognition failures and verification misjudgments caused by personnel positioning deviations, side face obstructions, or head rotations. At the same time, the camera has clean, high-definition imaging characteristics, which can automatically weaken the imaging interference caused by dust, slight stains, and light noise in the image, ensuring that the captured image is high-definition and clean. Together with the processing and storage system, it completes multi-dimensional feature comparison and verification, greatly improving the accuracy of identity verification and the error tolerance rate, further enhancing the reliability of the device verification, and adapting to multi-scene verification operations with complex postures and complex lighting. Understandably, as a better implementation method, a transparent dustproof and waterproof protective cover can be added to the outside of the clean high-definition capture camera 5 to isolate outdoor dust, moisture, and fingerprint stains, continuously maintain the lens in a clean and high-definition state, and adapt to harsh scenes such as open-air and dusty environments; the camera can be set to an electrically adjustable angle structure, which can automatically adjust the pitch angle according to the height of the person, adapt to the verification personnel of different heights, and improve the completeness of the capture; an intelligent supplementary lighting linkage structure can also be added, which starts and stops synchronously with the camera's capture action, automatically supplementing light in low light and backlight environments, ensuring clear capture of multi-dimensional features in low light environments. In addition, various alternative structures can be used to replace the top-mounted fixed clean high-definition capture camera 5: a retractable hidden camera structure can be used, which can be stored inside the housing 1 when not in use and pops out to capture images when in operation, further improving the portability and lens protection of the device; a dual-camera linkage capture structure can be used, with main and auxiliary dual cameras to achieve all-round capture without blind spots, further enriching the dimensions of personnel features and eliminating blind spots in recognition; a wide-angle fisheye capture structure can be used to expand the imaging field of view, and multi-dimensional feature capture can be completed without the need for precise personnel positioning, simplifying the verification process.

[0040] Preferably, the processing and storage system includes a main control unit and a storage unit. The main control unit adopts an ARM architecture multi-core processor and is used to coordinate the operation of the ID card reading module 41, the facial liveness detection module 42, and the ticket information recognition module 43, and to perform verification comparison and feature analysis. The storage unit is used to store verification records, captured feature images, and associated timestamped video stream data. Specifically, the main control unit adopts a domestically produced ARM architecture multi-core processor (such as Rockchip RK3399), which is responsible for running the operating system (such as Linux), coordinating the operation of the ID card reading module 41, the facial liveness detection module 42, and the ticket information recognition module 43, and executing verification comparison and feature analysis algorithms. During operation, the ARM architecture multi-core processor can synchronously coordinate the simultaneous start and stop of multiple modules such as ID card reading, liveness detection, and ticket recognition, preventing verification lag and response delays caused by multiple modules working in a time-sharing manner. It also performs complex computational logic such as cross-comparison of person, ID card, and ticket information, multi-dimensional feature analysis of personnel, and abnormal data identification, thereby improving the overall verification speed and data processing accuracy. The independently configured storage unit can selectively categorize and store verification ledger records, high-definition captured feature images, and timestamped video stream data, achieving integrated archiving of text, video, and ledger data. This overcomes the limitations of traditional devices that can only store simple text records and cannot retain image traceability data, improving the integrity, traceability, and credibility of verification data. It is suitable for high-frequency, high-requirement, and traceable verification operations in multiple scenarios. As a better implementation, a data encryption module can be added inside the storage unit to encrypt and store retained personnel images, identity information, and video data, preventing privacy data leakage and tampering, and improving device data security. A temperature-controlled heat dissipation structure can be added to the main control unit to avoid heat buildup and frequency reduction during high-load multi-core processor operations, ensuring stability during long-term continuous verification. Automatic overwrite and fixed-point backup mechanisms can be configured in the storage unit to support automatic cleaning of old data and locking and retaining important data, balancing device storage space and data traceability requirements.

[0041] Preferably, the foldable portable ID card and ticket verification device further includes a power supply module, which is located in the housing 1. The power supply module is electrically connected to the integrated ID card and ticket verification system 4 and the processing and storage system, respectively, and is used to supply power to both systems. Specifically, by integrating a dedicated power supply module inside the housing 1 and independently providing unified power supply support to the integrated ID card and ticket verification system 4 and the processing and storage system, the traditional external power adapter and wired power supply method is replaced, enabling the entire device to achieve an integrated power supply structure design. During operation, the power supply module can provide stable and continuous rated operating voltage and current to all verification function modules and data processing and storage units, ensuring the synchronous and stable operation of multiple processes such as ID card reading, liveness detection, ticket recognition, data processing and storage, and image capture. This avoids problems such as recognition failure, data loss, and device restart caused by voltage instability and power supply fluctuations when multiple modules are working simultaneously. The integrated built-in power supply structure eliminates the limitations of traditional equipment that relies on AC outlets and power cords. Combined with its foldable and portable design, the equipment can operate freely without a fixed power source, adapting to complex scenarios without a fixed power supply, such as outdoor work, mobile inspections, and temporary site verifications. This further enhances the equipment's multi-scenario adaptability and independent operation capabilities. As a further optimization, overvoltage, overcurrent, short-circuit, and overheat protection circuits can be added within the power supply module to prevent circuit damage caused by high load operation, excessively high ambient temperatures, or abnormal wiring, thus improving the equipment's electrical safety and lifespan. Real-time remaining power monitoring and intelligent low-battery alerts can also be added, allowing staff to promptly monitor the equipment's power status and recharge in advance, avoiding power outages and work stoppages. A fast-charging power supply structure can also be configured to significantly shorten charging time and improve the equipment's continuous operation endurance.

[0042] Preferably, the power supply module is made of a detachable battery pack and has a charging interface. Specifically, the power supply module can use a detachable high-capacity lithium battery pack, supporting continuous operation for no less than 8 hours. It is also equipped with a DC12V power interface, supporting vehicle charging or AC charging. During operation, the detachable battery pack can be quickly replaced with a backup battery after the battery is depleted, without requiring the entire machine to stop for charging, ensuring continuous and uninterrupted verification operations. This effectively solves the problems of limited battery life, long charging time, and inability to operate continuously with traditional integrated battery devices. With a DC12V universal charging interface, the device can be recharged indoors using AC power, or instantly charged using vehicle power in outdoor inspections, mobile duty, and vehicle-mounted scenarios, adapting to various complex operating scenarios such as fixed locations, outdoor mobile operations, and vehicle-mounted mobile operations, improving the device's battery life flexibility and scenario adaptability. It is understandable that, as a better implementation method, an anti-misinsertion locking structure can be added to the docking position between the detachable battery pack and the housing 1 to ensure accurate battery installation and removal, and a secure connection, preventing loosening and power loss during operation; a dustproof and waterproof plug and an overcharge protection structure can be added to the DC12V charging interface to prevent dust and moisture accumulation at the interface and overcharging damage to the battery, thereby improving charging safety and structural durability; a digital power display function can also be added to display the remaining power in real time, making it convenient for staff to predict the battery life in advance and replace or recharge the battery in time, ensuring operational stability. In addition, several alternative structures can be used to replace the power supply structure of this detachable battery pack with a DC12V charging interface: a dual power supply structure of built-in high-capacity battery + external power bank can be used to support the combination of onboard battery life and external expansion battery life, further extending the continuous operation time; a Type-C fast charging + DC dual interface power supply structure can be used to meet the needs of portable fast charging and high-power voltage regulated charging, and adapt to more charging devices; a detachable lithium battery pack structure with intelligent voltage regulation can be used to automatically regulate the output voltage in high and low temperature environments, and adapt to continuous power supply operation in outdoor extreme temperature scenarios.

[0043] Preferably, the hinge device includes a hinge seat 31 and a hinge shaft 32. The hinge seat 31 is disposed on the support base 2, and the hinge shaft 32 is disposed on the housing 1. The hinge seat 31 and the hinge shaft 32 are connected by a damped hinge. Specifically, by adopting a split-type damped hinge structure with the hinge seat 31 and the hinge shaft 32 cooperating, the traditional ordinary undamped hinge and snap-on limiting hinge structure are replaced, enabling the support base 2 and the housing 1 to achieve damped self-locking positioning at any rotation angle. During operation, through the damped frictional cooperation between the hinge seat 31 and the hinge shaft 32, the operator can freely adjust the opening and closing tilt angle of the housing 1 according to the on-site operating height, personnel posture, and placement table environment, achieving suspension and fixation without relying on fixed-position snap-on buckles. This effectively avoids the problems of traditional hinge structures that can only be limited to fixed points, have a single angle adjustment, and poor adaptability. Meanwhile, the split-type seat shaft assembly structure boasts high precision and small clearance, preventing slight shaking and displacement during equipment verification operations. This ensures the stability of the housing 1's placement posture and avoids malfunctions such as blurred facial capture, card reading failure, and document recognition misalignment caused by equipment shaking. This improves the overall operational stability of the equipment while also meeting the functional requirements of foldable storage and multi-angle support, further adapting to flexible verification operations in various scenarios. It is understood that, as a better implementation method, wear-resistant damping pads can be added to the contact surfaces between the hinge seat 31 and the hinge shaft 32 to improve damping uniformity, prevent damping attenuation and loosening / slippage due to long-term opening and closing, and extend the service life of the hinge structure. Limiting edges can be added to both ends of the hinge seat 31 to limit the maximum opening angle, preventing excessive flipping that could lead to wire breakage or structural damage from impacts. Furthermore, anti-detachment limiting screws can be added to the end of the hinge shaft 32 to prevent loosening due to long-term vibration, ensuring the overall structural assembly's robustness.

[0044] Preferably, the foldable portable ID verification device further includes a dual-mode communication module 6 and an operation panel 7. The dual-mode communication module 6 is detachably electrically connected to both the processing and storage system and the operation panel 7. The dual-mode communication module 6 is used to transmit data information from the processing and storage system to the operation panel 7. The operation panel 7 has real-time image viewing and playback functions. Specifically, the dual-mode communication module 6 has a standalone mode and a network mode. In standalone mode, the device can work independently in environments without a fixed network by using its built-in 4G / 5G mobile communication module and Wi-Fi module, encrypting the verification data and uploading it to the public security cloud platform. In network mode, the device can quickly build a local area network with multiple similar devices in the vicinity via Wi-Fi or Mesh self-organizing network technology. In temporary checkpoint scenarios, one device acts as the host, and the other devices act as slave devices. Data can be aggregated within the local area network and uploaded uniformly to achieve coordinated deployment. During operation, the detachable docking structure stably establishes a data transmission link between the processing and storage system and the operation panel 7, enabling real-time preview of verification screens, playback of historical screens, and synchronous transmission of ledger data, ensuring the stable operation of the equipment's core functions of local visual verification and anomaly review and tracing. Simultaneously, the detachable electrical connection structure allows for individual disassembly and repair of faulty components in case of module failure, panel damage, or aging wiring, eliminating the need for complete disassembly or replacement of the entire device, thus reducing maintenance difficulty and costs. The modular detachable structure also allows for flexible assembly or disassembly of communication and display components according to on-site operational needs. In a lightweight configuration, the equipment's weight can be further reduced, enhancing portability and adapting to various working conditions such as lightweight mobile duty and large-scale rapid passage verification, further improving the equipment's versatility in different scenarios. It is understandable that, as a better implementation method, a foolproof quick-connect structure can be set at the detachable electrical connection port to ensure accurate alignment and convenient plugging / unplugging, while preventing damage to the circuit due to mis-plugging; a flexible gold-plated contact structure can be added at the contact point to improve conductivity stability and avoid data disconnection and screen lag caused by poor contact due to frequent disassembly and assembly; a disassembly and assembly locking buckle structure can also be added to automatically lock after assembly to prevent the interface from loosening and causing power loss or transmission interruption during equipment movement or vibration, ensuring stable data transmission throughout the operation.

[0045] Preferably, both the housing 1 and the support base 2 are telescopic structures. Specifically, by adopting a telescopic nested structure design for the housing 1 and the support base 2, the overall size of the equipment can be freely adjusted according to the usage scenario. During operation, when the equipment is stored, transported, or carried, the housing 1 and the support base 2 can be completely retracted to their minimum travel state, compressing the overall length and width of the equipment. Compared to a simple folding structure, this further reduces the storage volume, making it more suitable for storage in pockets, small bags, and confined spaces, as well as for short-distance personal duty. During on-site verification operations, the telescopic travel of the housing 1 and the support base 2 can be extended according to the table height, personnel verification distance, and operational visibility requirements, achieving adaptive adjustment of the overall height and support span of the equipment to meet the usage needs of different operator heights, different work surfaces, and different verification distances. It is understandable that, as a better implementation method, a multi-level positioning buckle structure can be added to the telescopic cooperation position to achieve precise locking of the telescopic stroke level and prevent it from retracting and loosening during operation; anti-slip and wear-resistant damping strips can be built into the telescopic nesting gap to ensure smooth telescopic pushing and pulling and stable positioning, and to avoid gap shaking during long-term telescopic use; a limiting anti-detachment structure can also be set at the end of the telescopic structure to prevent excessive stretching from causing structural detachment and damage to internal wiring, thus ensuring the structural integrity and safety of the equipment.

[0046] Preferably, the ID card reading module 41 is made of a contactless IC card reader. Specifically, it adopts a contactless IC card reader that conforms to the Ministry of Public Security's GA45 standard. During operation, the verification personnel only need to bring the second-generation ID card close to the device's sensing area to complete the information reading, without the need for card insertion or contact friction. This effectively avoids the problems of card wear, interface wear, poor contact, and high card reading failure rate that exist in traditional contact reading methods, improving card reading response speed and recognition stability. At the same time, the contactless sensing reading method has no physical contact wear, which can adapt to high-frequency, large-volume continuous verification operations, extend the module's service life, and support close-range contactless card reading. It is convenient to operate, has a large fault tolerance range, and is suitable for verification needs in multiple scenarios with high traffic and fast passage, such as stations, scenic spots, and conference venues, further improving the overall verification efficiency and operational reliability of the equipment. It is understandable that, as a better implementation method, an anti-metal interference shielding structure can be integrated on the outside of the contactless IC card reader to eliminate the impact of desktop metal materials and electromagnetic interference from surrounding electronic devices on card reading accuracy and improve card reading stability in complex electromagnetic environments. A card reading status audio-visual prompt function can be added, outputting different prompt signals for successful card reading, card reading error, and no card detection, making it easier for staff to quickly determine the operation status. Furthermore, the sensing distance and sensing angle can be optimized to expand the card reading sensing range, reduce the difficulty of document alignment, and further simplify the verification process.

[0047] Preferably, the human face liveness detection module 42 is made in combination with an infrared camera and a visible light camera. Specifically, it uses an infrared camera with at least 2 megapixels and a visible light camera, along with a built-in chip for detection (such as blinking, opening the mouth, shaking the head, and other action commands) to ensure that the verifier is a real person and prevent it from being a photo or video. During operation, the visible light camera is responsible for acquiring high-definition color facial images, completing basic recognition work such as facial feature capture, face comparison, and facial feature information matching, ensuring the clarity of facial imaging and comparison accuracy under normal lighting conditions; the infrared camera captures the infrared features of a living human body through infrared imaging principles, and can identify real human skin temperature, live texture, and microcirculation features, effectively filtering out various forgery attacks such as color photos, printed images, screen videos, and simulated human face masks. The dual cameras work together and complement each other, retaining the advantages of visible light imaging in terms of true color and rich detail, while also possessing the characteristics of infrared imaging that are not affected by ambient light and are specifically used for liveness detection, improving the accuracy, security, and environmental adaptability of the device's facial verification, and meeting the needs of reliable verification in multiple scenarios and all weather conditions. It is understandable that, as a better implementation method, a synchronous focusing linkage control structure can be adopted for the dual cameras to ensure that the imaging position, focal length, and field of view of the infrared and visible light images are completely synchronized, avoiding the impact of misalignment between the two images on the accuracy of feature comparison. A dynamic light adaptive adjustment algorithm can be added to automatically switch the dual-camera primary and secondary working modes according to the ambient light intensity, prioritizing infrared imaging in strong light and coordinating dual-camera supplementary lighting imaging in low light. Furthermore, intelligent face region cropping and enhancement functions can be added to remove background interference and enhance facial detail features, further improving the computational efficiency and accuracy of liveness detection and face comparison. In addition, several alternative structures can be used to replace this infrared + visible light dual-camera combination structure: a three-spectrum camera combination structure can be used, adding a near-light supplementary spectral channel to further improve the recognition stability in extremely low light and backlight scenes; an integrated binocular liveness camera structure can be used, using a binocular parallax algorithm to achieve 3D face modeling and improve the anti-counterfeiting level; an AI intelligent single-camera multi-mode imaging structure can be used, using algorithms to simulate the imaging effects of infrared and visible light dual modes, simplifying the hardware structure, reducing the size of the device, and further improving the portability of the device.
