[0034] This utility model proposes a card swiping device 1000.

[0035] Please see Figure 1 , Figure 2 , Figure 4 as well as Figure 5 In one embodiment of this utility model, the card swiping device 1000 includes a housing 1, a card reading assembly, and an interface assembly. The housing 1 forms a mounting cavity 1a and a plug-in interface 1b, which communicate with each other. The housing 1 also forms a card swiping groove 1c for the user to swipe a card. The card reading assembly includes an NFC antenna, a magnetic stripe card reader 22, and an embedded card reading module 23. The NFC antenna is disposed in the housing 1 and located within the mounting cavity 1a. The magnetic stripe card reader 22 abuts against the opposite side walls of the card swiping groove 1c and is located within the mounting cavity 1a. The embedded card reader... The card module 23 is detachably connected to the housing 1 and engages with the bottom wall of the card reader groove 1c to receive the magnetic stripe card reader 22; the interface assembly includes an interface board 31, which includes a board body 311 and a USB interface for electrical connection with the tablet computer 2000. The board body 311 is snapped into the housing 1; the USB interface is located on the board body 311 and is electrically connected to the board body 311; the USB interface passes through the plug interface 1b and is exposed in the housing 1; the board body 311 is electrically connected to the NFC antenna, the magnetic stripe card reader 22 and the embedded card reader module 23 respectively.

[0036] In the technical solution of this utility model, the card swiping module integrates an NFC antenna, a magnetic stripe card reader 22, and an embedded card reader module 23, which can adapt to most card swiping methods (such as contactless card reading, card insertion, and card reading compatibility). Through the structure of the housing 1, multiple types of card reader modules are integrated, combining NFC contactless identification, magnetic stripe card contact reading, and expandable embedded modules into the same mounting cavity 1a. The interface component is used to achieve a compact plug-in connection with the tablet computer 2000, ensuring multi-functional compatibility while avoiding the volume redundancy caused by external devices. The card swiping device 1000 has a compact structure. Utilizing its own structural characteristics, the USB interface is plugged into the interface end of the tablet computer 2000, occupying less space and making it convenient for users. Thus, while realizing multiple card swiping functions, it can also take advantage of the portability of the tablet computer 2000.

[0037] When the card reader 1000 is working, the user can swipe a magnetic stripe card through the card reader slot 1c, and the magnetic stripe card reader 22 reads the information; the NFC antenna can read contactless card information. The embedded card reader module 23 processes the read information; the interface board 31 connects to the tablet computer 2000 through a USB interface to realize data transmission; all components are integrated into the housing 1 to form an integrated structure, which facilitates use with the tablet computer 2000.

[0038] In use, the card reader 1000 is installed on the tablet computer 2000, and the USB interface is connected to the tablet computer 2000. The user can swipe a magnetic stripe card in the card reader slot 1c, or bring a contactless card close to the NFC antenna for sensing. The read information is processed by the embedded card reader module 23 and then transmitted to the tablet computer 2000 via the USB interface.

[0039] Please see Figure 1 , Figure 2 as well as Figure 5 In one embodiment of this utility model, the housing 1 forms an arc surface 1d that adapts to the shape of the tablet computer 2000, and the insertion interface 1b is formed on the arc surface 1d. The arc surface 1d design allows the card reader 1000 to fit closely to the shape of the tablet computer 2000, improving the stability and aesthetics of the overall structure, while achieving seamless docking between the card reader 1000 and the tablet computer 2000; the insertion interface 1b is formed on the arc surface 1d, which facilitates connection with the tablet computer 2000 without affecting the overall appearance of the card reader 1000.

[0040] The curved surface 1d design allows the card reader 1000 to fit snugly against the shape of the tablet computer 2000. The interface 1b is located on the curved surface 1d and is used to connect the tablet computer 2000.

[0041] The curved surface 1d can be an arc shape, matching the curvature of the tablet PC 2000's edge. The connector 1b can be a rectangular opening located at the center of the curved surface 1d. The radius of curvature of the curved surface 1d can be adjusted according to different models of the tablet PC 2000 to ensure optimal fit.

[0042] Please see Figure 1 and Figure 3 In one embodiment of this utility model, the housing 1 forms a mounting opening 1e communicating with the mounting cavity 1a. The card reader 1000 further includes a fingerprint component, which includes a fingerprint module 41. The fingerprint module 41 has a pressing surface 41a for fingerprint recognition. The fingerprint module 41 is detachably connected to the periphery of the mounting opening 1e, so that the pressing surface 41a is exposed in the housing 1. The fingerprint module 41 is electrically connected to the plate 311. Integrating fingerprint recognition functionality into the card reader 1000 expands its functionality. The detachable design of the fingerprint module 41 facilitates maintenance and replacement; the pressing surface 41a is exposed outside the housing 1, making it convenient for users to perform fingerprint recognition operations and improving ease of use.

[0043] Specifically, the fingerprint module 41 can use a capacitive fingerprint sensor, and the pressing surface 41a is made of glass. The pressing surface 41a protrudes slightly from the surface of the housing 1 for easy user operation. The fingerprint module 41 is electrically connected to the interface board 31 to transmit the collected fingerprint information to the tablet computer 2000 for processing.

[0044] It is understood that the fingerprint module 41 can be detachably connected to the periphery of the mounting port 1e by either a threaded connection or a snap-fit ​​connection. In one embodiment of this utility model, the fingerprint assembly further includes a fingerprint bracket 42, which is detachably connected to the housing 1; a snap-fit ​​ring 411 is formed on the outer periphery of the fingerprint module 41, with both sides of the snap-fit ​​ring 411 abutting against the housing 1 and the fingerprint bracket 42 respectively, so as to snap the snap-fit ​​ring 411 between the housing 1 and the fingerprint bracket 42. During assembly, the fingerprint module 41 is embedded into the mounting port 1e of the housing 1 via the snap-fit ​​ring 411, and the annular step provides limiting support to the lower surface of the snap-fit ​​ring 411. Due to the snap-fit ​​structure, no additional fasteners are required, simplifying the assembly process. At the same time, the snap-fit ​​ring 411 is clamped between the housing 1 and the fingerprint bracket 42, which can effectively prevent the fingerprint module 41 from loosening or falling off. In addition, when it is necessary to repair or replace the fingerprint module 41, the fingerprint module 41 can be easily removed by simply removing the fingerprint bracket 42, improving the maintainability of the device. This not only ensures the stability of the fingerprint recognition function but also enhances the structural strength and service life of the entire card reader 1000.

[0045] Specifically, the fingerprint bracket 42 can be made of plastic or formed from metal stamping.

[0046] In one embodiment of this utility model, the interface assembly further includes a small board bracket 32, which is detachably connected to the housing 1. A limiting post protrudes from the inner wall of the housing 1. The small board bracket 32 ​​cooperates with the limiting post to engage the plate 311. The magnetic stripe card reader 22 and the embedded card reader module 23 are both detachably connected to the small board bracket 32. The small board bracket 32 ​​achieves lateral positioning of the plate 311 through the limiting post, and forms vertical load support by supporting the magnetic stripe card reader 22 and the embedded card reader module 23. Simultaneously, the cooperation between the small board bracket 32 ​​and the limiting post ensures the installation position accuracy of each component, thereby improving the overall stability of the card reader device 1000.

[0047] It is understood that the small board bracket 32, as an integrated load-bearing structure, has at least one detachable connection method, including snap-fit ​​or threaded connection. In one embodiment of this utility model, the card reader 1000 includes at least six first studs. Two first studs pass through the small board bracket 32 ​​and are threadedly connected to the magnetic stripe card reader 22. Two first studs pass through the small board bracket 32 ​​and are threadedly connected to the embedded card reader module 23. Two first studs pass through the housing 1 and are threadedly connected to the embedded card reader module 23. The small board bracket 32 ​​and the magnetic stripe card reader 22 are fixed at two points through the two first studs, limiting the horizontal displacement of the magnetic stripe card reader 22. The small board bracket 32 ​​and the embedded card reader module 23 form a clamping force through the two first studs, preventing the module from shaking in the vertical direction. The housing 1 and the embedded card reader module 23 provide additional support through the two first studs, dispersing the influence of external pressure on the module. Through the multi-point distribution of at least six studs, the components maintain close contact in the detachable state, improving the overall vibration resistance and making it suitable for frequent insertion / removal or movement scenarios.

[0048] In one embodiment of this utility model, the housing 1 includes a front shell 11 and a bottom shell 12. The front shell 11 and the bottom shell 12 are detachably connected and enclose the bottom shell 12 to form a mounting cavity 1a. A card-swiping groove 1c and an arc surface 1d are both formed on the front shell 11. An embedded card reader module 23 is detachably connected to the front shell 11. A plate 311 is snapped onto the front shell 11, and an NFC antenna is disposed on the bottom shell 12. The detachable connection between the front shell 11 and the bottom shell 12 facilitates the installation and maintenance of internal components. The embedded card reader module 23, the plate 311, and the NFC antenna are respectively mounted on the front shell 11 and the bottom shell 12, which optimizes the spatial layout and improves assembly efficiency. The detachable connection facilitates the replacement and upgrading of each module and extends the product's service life.

[0049] The front shell 11 and the bottom shell 12 are fixed by clips or screws, and the internal space of the mounting cavity 1a can be exposed after disassembly.

[0050] This utility model also proposes a tablet computer 2000, which includes a main body 5 and a card reader 1000. The specific structure of the card reader 1000 is as described in the above embodiments. Since this tablet computer 2000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The main body 5 is detachably connected to the housing 1; the main body 5 has a plug-in port, and a USB interface is plugged into the plug-in port.

[0051] The housing 1 of the card reader 1000 has an arc surface 1d that is adapted to the shape of the tablet computer 2000. The plug-in interface 1b is opened on the arc surface 1d, and the USB interface passes through the plug-in interface 1b and extends to the outside of the arc surface 1d. The main body 5 is electrically connected to the USB interface through the plug-in port. The housing 1 and the main body 5 adopt a detachable physical connection structure. The curvature of the arc surface 1d matches the edge contour of the main body 5 of the tablet computer 2000, so that the housing 1 and the main body 5 form a continuous outer surface after installation. The size of the plug-in interface 1b is aligned with the metal contact area of ​​the USB interface to ensure stable contact after plugging in.

[0052] Specifically, the tablet PC 2000 body 5 has an internal connector port, the position of which corresponds perfectly to the connector 1b on the housing 1 during assembly. When the housing 1 is fixed to the body 5 via a snap-fit ​​or threaded structure, the plug of the USB interface is directly inserted into the connector port of the body 5, establishing a data transmission channel. The curved surface 1d of the housing 1 conforms to the side of the tablet PC 2000, preventing protrusions or gaps after assembly. The detachable connection structure allows for quick installation of the housing 1 when card swiping functionality is needed, enabling the tablet PC 2000 body 5 to be used independently in portable scenarios. The USB interface not only provides power and data transmission but also enhances the connection strength between the housing 1 and the body 5 through the mechanical interaction between the interface and the connector port. Data from magnetic stripe cards and NFC cards collected by the card reader component inside the housing 1 is transmitted to the tablet PC 2000 processor via the USB interface, where the payment or verification program built into the body 5 completes the subsequent processing.

[0053] Please see Figure 1 , Figure 2 , Figure 4 as well as Figure 5In one embodiment of this utility model, the housing 1 has a mounting plane 1f connected to the arc surface 1d. The tablet computer 2000 also includes a mounting block 6, which is detachably connected to the body 5. The mounting block 6 forms a mounting groove 6a, and the bottom wall of the mounting groove 6a abuts against the mounting plane 1f, so that the housing 1 is snapped into the mounting groove 6a. The mounting block 6 adapts to the shape of the mounting plane 1f through the groove structure. The bottom wall of the groove contacts the mounting plane 1f to form a surface support, restricting the displacement of the housing 1 in the vertical direction. After the mounting block 6 is fixed to the body 5, the housing 1 is pushed into the mounting groove 6a along the direction of the mounting plane 1f, realizing the precise positioning and installation of the housing 1 and the tablet computer 2000 body 5. The reinforcing rib structure of the mounting block 6 effectively disperses the assembly stress and prevents deformation problems caused by long-term use. The precision mating surface of the mounting groove 6a forms a gapless fit with the mounting plane 1f, eliminating vibration and abnormal noise during equipment operation. This assembly method ensures the connection strength while allowing the housing 1 to be quickly disassembled and assembled through modular design, which is convenient for later maintenance and replacement.

[0054] Please see Figure 6 and Figure 7 In one embodiment of this utility model, the tablet computer 2000 includes at least two second studs 7 and at least two third studs 8. The second studs 7 pass through the housing 1 and are threadedly connected to the mounting block 6. The third studs 8 pass through the mounting block 6 and are threadedly connected to the body 5. The mounting plane 1f forms a movable groove 1f1 for each third stud 8 to move. The second studs 7 fix the housing 1 and the mounting block 6 through threaded connection, and the third studs 8 fix the mounting block 6 and the body 5 through threaded connection. The extending direction of the movable groove 1f1 is consistent with the extending direction of the mounting plane 1f, allowing the third studs 8 to move along a preset path within the mounting groove 6a. The threaded connection of the studs provides mechanical locking force, limiting the relative displacement between the mounting block 6 and the housing 1, and between the mounting block 6 and the body 5. The length and width of the movable groove 1f1 are adapted to the moving range of the third studs 8, ensuring that the mounting block 6 can still be locked by the third studs 8 after the position is adjusted. This solution solves the problems of insufficient stability in the connection between the mounting block 6 and the body 5 and difficulty in position adjustment by using the threaded connection of the stud and the cooperation of the movable groove 1f1. At the same time, it avoids the introduction of additional parts and maintains the overall structural compactness.

[0055] Specifically, during installation, the second stud 7 passes through the preset hole in the housing 1 and engages with the threaded hole in the mounting block 6, achieving initial fixation between the housing 1 and the mounting block 6. Subsequently, the third stud 8 passes through the connecting hole in the body 5 of the mounting block 6 and is inserted into the corresponding threaded hole in the body 5. By rotating the stud, the mounting block 6 is pressed against the body 5. The movable groove 1f1 provides space for the third stud 8 to adjust its position, allowing the mounting block 6 to move within the mounting plane 1f to accommodate different sizes or positions of the plug-in ports. After the mounting block 6 is adjusted to the target position, the third stud 8 is further tightened. The threaded engagement force eliminates the gap between the mounting block 6 and the body 5, while the sidewall of the movable groove 1f1 restricts the displacement freedom of the third stud 8, ensuring a stable engagement between the mounting block 6 and the housing 1.

[0056] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
