[0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art.

[0003] Most existing ID card readers are desktop, portable, and vertical devices. They are large in size and inconvenient to carry. They need to rely on other terminal devices to read the displayed information. They are not convenient to carry and use in industries such as plainclothes police. For example, when a suspicious person is found, the hands holding the ordinary card reader can be freed to take measures against the suspicious person.

[0004] Current card readers do not have smart wearable properties and are easily lost while on duty. In addition, the devices require a specific power supply and are not suitable for working in special environments such as the wild. At the same time, ordinary card reader devices only have a single card reading function without face matching and general electronic meter functions. At the same time, the ID card module built into the traditional card reader is large in size, occupies a large space in the device, and has only a single antenna card reading area, and cannot read two cards at the same time. Utility Model Content

[0005] In order to solve the technical problems existing in the prior art, the utility model provides an intelligent wearable card reader that can be worn on the wrist like a watch, and the host part can be disassembled and replaced, and can be used separately without the wristband. At the same time, the host can be adsorbed on other hardware devices and used as a common card reader device.

[0006] To achieve the above purpose, the utility model is implemented through the following technical solutions:

[0007] A smart wearable card reader comprises a host and a wristband connected thereto, wherein the host comprises an upper shell, wherein the outer periphery of one side of the upper shell is fixedly connected to a rear shell via an intermediate bracket to form an inner cavity, a mainboard is fixedly arranged on the intermediate bracket of the inner cavity, a security code chip is fixedly arranged on the surface of one side of the mainboard, and the security code chip is connected to the mainboard; a lens is fixedly arranged on the outer surface of the other side of the upper shell, and a first antenna is fixedly arranged at the outer periphery, and the lens and the first antenna are connected to the mainboard.

[0008] According to a further technical solution, the lens is a non-transparent mirror screen.

[0009] According to a further technical solution, the first antenna is a loop antenna.

[0010] According to a further technical solution, the mainboard is equipped with a sensor and a processing chip.

[0011] According to a further technical solution, a second antenna is provided in the wristband.

[0012] According to a further technical solution, the second antenna is connected to the mainboard via a magnetic spring pin.

[0013] According to a further technical solution, the second antenna is a non-closed antenna.

[0014] According to a further technical solution, the wristband is connected to the host by magnetic attraction.

[0015] According to a further technical solution, a communication contact of a second antenna is provided at the connection position between the wristband and the host.

[0016] According to a further technical solution, a battery is fixedly provided on the rear shell in the inner cavity, and the battery is connected to the mainboard.

[0017] Beneficial effects of the utility model:

[0018] The utility model can be worn on the wrist like a watch, and the wristband and the host are adsorbed so that the host part can be disassembled and replaced, and can be used separately from the wristband. The host can also be adsorbed on other hardware devices to act as a common card reader device, which greatly increases the flexibility of the device.

[0019] The utility model transforms the card reader into a wearable card reader device, so that the card reader is no longer a single-function device.

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] See also Figure 1 As shown, an embodiment of the utility model provides an intelligent wearable card reader, including a host and a wristband connected thereto, the host including an upper shell 8, the outer periphery of one side of the upper shell 8 is fixedly connected to a rear shell 10 through an intermediate bracket 9 to form an inner cavity, a main board 6 is fixedly arranged on the intermediate bracket 9 of the inner cavity, a security password chip 5 is fixedly arranged on the surface of one side of the main board 6, and the security password chip 5 is connected to the main board 6; a lens 4 is fixedly arranged on the outer surface of the other side of the upper shell 8, a first antenna 3 is fixedly arranged at the outer periphery, and the lens 4 and the first antenna 3 are connected to the main board 6.

[0028] The smart wearable card reader in this embodiment is mainly used in the field of ID card recognition and information verification. The card reader device can be worn portablely to read ID cards and verify facial information.

[0029] In this embodiment, the lens 4 is a non-transparent mirror screen, which is connected to the main board through the pin points on the main board 6. The face can be mapped on the lens based on the mirror principle. The image capture technology is used to collect the image of the face mapped on the lens and save it to the main board for comparison with the card image. At the same time, the lens can also display the card image read by the antenna sent by the main board, and display the ID card image information in real time when needed. The lens screen also has a touch function.

[0030] The lens fixed on the outer surface of the upper shell innovatively uses screen mapping image comparison to collect faces. You only need to face the mirror screen directly, and the mirror screen will collect holographic 3D information of the face. In other words, the image capture technology is used, that is, the mirror screen is a mirror. After the face is captured, the GPU graphics processor takes a screenshot of the mirror screen and compares it with the ID card photo stored in the database. There is no need to use a camera to collect face images, which reduces the complexity of the equipment and does not require additional search or adjustment of the camera's position and direction. The operation is simple and fast, which improves the user experience.

[0031] In some embodiments, the lens 4 is fixed to the upper shell by gluing, and is in the shape of a circular lens that matches the shape and size of the outer surface of the upper shell 8. This embodiment does not specifically limit the fixing method, and it can be selected and set according to actual conditions.

[0032] In this embodiment, the first antenna 3 is fixed to the outer circumference of the upper shell 8. It is a ring antenna distributed in a circle and can read identity cards. At the same time, the first antenna 3 is connected to the main board 6 to transmit the card image read by the antenna to the main board for comparison.

[0033] The first antenna 3 is physically connected to the mainboard 6. The mainboard 6 is provided with a spring pin, and the first antenna 3 is provided with a metal-plated pin. The spring pin is physically contacted with the metal-plated pin to achieve electrical connection between the two and realize signal transmission.

[0034] In this embodiment, the middle bracket 9 is a disc-shaped groove bracket, and its groove is hollowed out. The middle bracket 9, that is, the groove is fixed with a mainboard 6. The mainboard 6 is connected to the battery 7 located between the middle bracket and the rear shell through the hollowed-out groove, and is also connected to the second antenna in the wristband through the hollowed-out groove. The mainboard 6 is a core component, and the middle bracket 9 is designed to provide a stable and firm support platform for the mainboard 6, ensuring the working stability of the mainboard and preventing it from being damaged by shaking or external impact.

[0035] The upper shell 8 and the rear shell 10 are both disc-shaped, and the sizes and shapes of the upper shell 8, the middle bracket 9 and the rear shell 10 are adapted to each other, and together form a closed space.

[0036] In this embodiment, the main board 6 is a printed circuit board PCBA, and various sensors and processing chips for realizing corresponding functions are mounted on the main board 6; the sensors include air pressure sensors, temperature sensors and satellite positioning sensors, and the processing chips are functionally air pressure sensor chips, temperature sensor chips and GPS chips. At the same time, the processing chip also includes a GPU graphics processor, which is used to compare the face image with the card image and obtain the comparison result.

[0037] It should be noted that the mainboard receives the card image read by the first antenna and the second antenna, receives the face image captured by the mirror screen mapping, compares the face image with the card image, and displays the passing result on the mirror screen if the comparison passes, and performs an error processing when the comparison fails. The above functions are realized by using an existing GPU graphics processor for processing, which belongs to the processing function of the processing chip itself and does not involve improvements to the software program; each processing chip is also an existing chip, which is installed on the mainboard 6 and is connected to the wires and connection points of the printed circuit board PCBA by welding or insertion to form a complete circuit. The chip models are not limited here, and the connection method is known to those skilled in the art, and any chip that can achieve the corresponding function can be used.

[0038] A security password chip 5 is also fixed on the main board 6 and connected to the main board 6. The main board reads the ID card number and photo through the security password chip, and then sends them to the GPU graphics processor for comparison with the facial image captured by the lens screen; the security password chip 5 integrates multiple security functions and algorithms, has a high degree of security and reliability, protects personal identity information, and provides a safer and more limited identity recognition method. The existing security password chip is used for identity recognition. The chip model is not limited here. Any chip that can achieve the corresponding function can be used, and no improvement to the software program is involved.

[0039] In this embodiment, a second antenna 12 is provided in the wristband 11 and is connected to the main board 6 in the host. It reads the ID card information when linked with the host. It can read the ID card information simultaneously with the first antenna 3 on the outer surface of the upper shell 8, and can perform dual ID card reading, or when one antenna is damaged, start the other antenna to realize the ID card reading function, thereby increasing the reliability of the device.

[0040] The wristband 11 is connected to the host by magnetic attraction and can be disassembled and replaced. The connection position of the entire wristband and the host is provided with a communication contact of the second antenna 12; the connection position of the wristband and the host is provided with a magnetic spring pin, which is connected to the two pins extending from the main board 6 to achieve the connection between the main board 6 and the second antenna 12, and realize the linkage with the host. The wristband 11 is worn on the wrist and can adapt to the wrist size; the second antenna 12 on the wristband is a non-closed loop antenna, and the antenna can be tightened and scaled according to the adaptation of the wristband.

[0041] In this embodiment, a battery 7 is fixedly provided on the rear shell 10 in the inner cavity of the host, that is, the battery 7 is fixedly installed in the cavity between the intermediate bracket 9 and the rear shell 10. The battery 7 is connected to the mainboard to provide power for the mainboard and various chips on the mainboard.

[0042] In some embodiments, the battery 7 is a button battery, which provides power to various components in the card reader to realize corresponding functions. The battery 7 is connected to the main board 6 through a spring clip for power supply, and the lens 4 is connected to the main board through the spring pin point on the main board 6 to realize the power supply of the lens.

[0043] In this embodiment, the host and the wristband are detachable. The host part can be removed and replaced. It can be used independently without the wristband, and it can also be attached to other hardware devices to act as an ordinary card reader device. The host part also has the functions of an ordinary electronic watch and can display basic parameters such as time. At the same time, the host and the wristband are a closed structure, which can support IP68 protection and can be used in extreme environmental conditions.

[0044] Working principle details:

[0045] First, wear the wristband 11 on the wrist and attach the host to the wristband 11. At this time, the card reader device senses the suction action and turns on. After the first antenna 3 and the second antenna 12 have the card reading function, place the ID card close to the first antenna or the second antenna, or place two ID cards on the first antenna 3 and the second antenna 12 respectively, and the ID card information can be read; the ID card information includes the card number and the card picture. The main board parses and reads the ID card number and photo through the security password chip connected to it, and then sends them to the GPU graphics processor for comparison with the face image captured by the lens screen.

[0046] When portrait capture is required, the face only needs to be placed facing the lens 4, and the lens 4 will capture holographic 3D information of the face. The GPU graphics processor on the main board 6 will then take a screenshot to obtain the face image and compare the face image with the card image read by the antenna. If the comparison is successful, the result will be displayed. If the comparison fails, an error will be reported.

[0047] Furthermore, during the card reading process, the device uses the default trigger card reader, eliminating the need to manually open the card reading software. That is, when the card approaches the antenna, the card reading mechanism is triggered and the card information begins to be read and analyzed.

[0048] The host part can be removed from the wristband 11, and the first antenna 3 can be used alone to read the ID card. At the same time, the host part can be adsorbed on the back of other hardware devices (screen display devices such as mobile phones) by magnetic attraction. The host and other hardware communicate with each other through wireless methods such as Bluetooth communication, so that the ID card information read by the host can be transmitted to other hardware devices in real time.

[0049] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
