Description

Technical Field

[0001] This utility model relates to the field of card transmitter technology, and in particular to an NFC card transmitter. Background Technology

[0002] Card games, as one of the most popular game categories on the market, have long been favored by many players. Traditional card games typically use playing cards as the medium, with images and information printed on the card surface. During the game, players mainly understand the information represented by the cards by visually viewing the images on the cards, and then act and compete according to the established game rules. However, this traditional card game model has many significant drawbacks, severely restricting its further development and the improvement of the player experience.

[0003] Traditional card games are limited to the information conveyed by the printed images on the cards. Cards serve only as static information display tools, lacking diverse functional expansion. For example, during gameplay, players can only make decisions based on the fixed images and text on the cards, unable to achieve more complex and richer gameplay. This functional limitation makes traditional card games inadequate in meeting the increasingly diverse and personalized needs of players, failing to attract long-term player attention and participation.

[0004] Furthermore, the interactivity of traditional card games primarily relies on face-to-face communication and actions between players. Players interact by directly exchanging cards and verbally exchanging strategies. However, this interaction method is limited by time and space; players must play in the same location and at the same time, greatly restricting the scope and flexibility of the game. In addition, due to a lack of effective technical support, the forms of interaction between players are relatively simple, making it difficult to achieve deeper and broader interactive experiences and failing to meet the needs of modern players for social interaction and game diversity.

[0005] Furthermore, paper cards lack electronic storage capabilities, a characteristic that prevents traditional card games from achieving online interaction. In today's digital age, players have higher expectations for the convenience, real-time nature, and social aspects of games. Because traditional card games cannot connect online, players cannot engage in real-time battles, communicate, or share game experiences with other players, significantly reducing the game's fun and appeal. At the same time, the lack of competitive elements also makes traditional card games significantly less effective in stimulating players' competitive spirit and sense of accomplishment.

[0006] In conclusion, traditional card games suffer from numerous problems in terms of functionality, interactivity, and participant experience, making them unable to adapt to the development of the modern game market and the needs of players. Therefore, developing a card game format with innovative features, high interactivity, and a superior experience has significant practical importance and market value. Utility Model Content

In addition, those skilled in the art can combine and integrate the different embodiments or examples described in this specification.

[0032] See Figs. 1 to 3 The specific embodiment shown in this utility model discloses an NFC card transmitter, including: a housing 10, a main control board 20 inside the housing 10, an NFC sensor 30 inside the main control board 20, and at least one NFC card 150 placement area in the housing 10, the placement area corresponding to the NFC sensor 30, and a card tray 40 for supporting the NFC card 150 below the placement area.

[0033] Specifically, by burning the card information into the NFC chip during printing, a high degree of integration between the card's visual information (printed content) and electronic information (NFC chip stored content) is achieved, resulting in the NFC card 150. When players acquire the card, they can intuitively understand its basic features through the printed pattern and quickly read the detailed information within the chip using the NFC sensor 30, greatly improving information acquisition efficiency. Furthermore, NFC technology features rapid response. When the NFC card 150 is placed in the transmitter's placement area, the NFC sensor 30 can establish communication with the chip within the card in a very short time and read its information. This allows players to quickly obtain card information during gameplay, accelerating the game's pace, reducing waiting time, and improving the game's smoothness and overall experience. Another advantage of using NFC technology is that it eliminates the need for separate power to the card while storing information. This means the NFC card 150 does not require a built-in battery or other power source, simplifying card design and manufacturing processes and reducing costs. It also avoids the inconvenience of running out of battery power or needing to replace it, improving the card's ease of use and reliability. Because it requires no power source, the information on the NFC Card 150 can be stably stored in the chip for a long time without being lost or damaged due to battery issues. Players can store and use these cards for an extended period without worrying about them becoming unusable due to power problems, thus extending the lifespan of the cards.

[0034] The combination of the transmitter and the NFC card 150 offers more possibilities for game development. Game developers can design more diverse and innovative gameplay based on the rich information stored in the NFC card 150. For example, by combining and interacting with different card information, special game events or skill effects can be triggered, increasing the game's strategy and fun. Furthermore, leveraging NFC technology and network connectivity, the transmitter can achieve cross-platform game interaction. Players can not only compete or cooperate with other players locally, but also communicate and compete with players worldwide via the internet, expanding the game's social reach and influence.

[0035] In other words, when the NFC card 150 is placed on the corresponding placement area of ​​the transmitter housing 10, the NFC sensor 30 can quickly interact with the card. This means that players are no longer limited to playing in the same location. With the help of NFC communication, card information transmission and interaction can be easily achieved remotely or across regions, enhancing the interactivity and convenience of the game and meeting the needs of modern players for social interaction and flexibility in games. In addition, the NFC sensor 30 on the main control board 20 can quickly read the rich information stored in the card, such as card attributes, skills, character background, etc., and transmit this information to the game terminal in real time. This makes the game process richer and more diverse. Players can formulate diverse strategies based on different card information, increasing the strategic depth of the game. At the same time, combined with the network function, players can also obtain more dynamic game content, such as limited-time events and special tasks, further enhancing the fun and attractiveness of the game and bringing players a brand-new gaming experience. In addition, the card tray 40 set below the placement area not only provides stable support for the card, but also ensures a stable and accurate data connection between the card and the NFC sensor 30.

[0036] In one embodiment, the housing 10 is further provided with a semi-open baffle 50 in the placement area, the card tray 40 is slidably connected to the housing 10, and the thickness of the NFC card 150 is greater than the gap between the card tray 40 and the baffle 50.

[0037] Specifically, when the NFC card 150 is inserted into the placement area, because the thickness of the NFC card 150 is greater than the gap between the card tray 40 and the baffle 50, the card tray 40 presses down on the main control board 20 to trigger the circuit. After receiving the trigger signal, the main control board 20 activates the NFC sensor 30. More specifically, the card tray 40 is typically made of a material with a certain strength and toughness, such as plastic. Its shape should be adapted to the shape of the placement area and designed to facilitate sliding. For example, slide rails or protrusions can be provided on both sides of the card tray 40 to cooperate with corresponding grooves or recesses inside the housing 10. Grooves or recesses matching the slide rails or protrusions of the card tray 40 are machined inside the housing 10 at the position corresponding to the placement area. The size and precision of the grooves or recesses must be strictly controlled to ensure that the card tray 40 can slide smoothly within them while preventing it from becoming loose or falling off during sliding. The card holder 40 is installed inside the housing 10 so that its slide rail or protrusion is accurately embedded in the slide groove or recess, thereby achieving a sliding connection between the card holder 40 and the housing 10.

[0038] A corresponding trigger circuit is designed on the main control board 20. This circuit should include a trigger element such as a pressure sensor or a contact switch. The trigger element should be precisely positioned on the downward pressing path of the card tray 40 to ensure that the trigger element is accurately pressed when the card tray 40 is pressed downward by the NFC card 150. When the card tray 40 presses down on the trigger element on the main control board 20 due to the insertion of the NFC card 150, the trigger element generates an electrical signal. This electrical signal is transmitted to the main control chip (the main control board 20 is equipped with a main control chip) through the internal circuitry of the main control board 20. After receiving the trigger signal, the main control chip will activate the NFC sensor 30 according to a pre-set program, enabling it to start working and prepare to read the information in the NFC card 150.

[0039] In other words, by setting a semi-open baffle 50, a sliding card tray 40, and precisely controlling the gap between the card tray 40 and the baffle 50, it is ensured that the card tray 40 will only press down on the main control board 20 to trigger the circuit when the NFC card 150 is correctly inserted into the placement area, as the card thickness exceeds the gap. This design avoids false triggering caused by misoperation or other foreign objects entering the placement area, improving the accuracy and reliability of the triggering mechanism. Furthermore, when the main control board 20 does not receive a trigger signal, the NFC sensor 30 remains off and does not consume power. The NFC sensor 30 only starts working after the NFC card 150 is inserted and triggers the main control board 20. This on-demand activation design effectively reduces the overall power consumption of the transmitter, extends the battery life of the battery 130, and improves energy efficiency. Additionally, the semi-open baffle 50 design allows players to easily insert the NFC card 150 into the placement area without complicated operating procedures. Meanwhile, the sliding card tray 40 automatically adapts to card insertion and smoothly descends to trigger the main control board 20 under the action of the card, providing players with a simple and convenient operating experience. Because the card tray 40 and the housing 10 are slidably connected with precise gap control, the smoothness and stability of movement are ensured during card insertion and the downward movement of the card tray 40. This helps reduce the impact of mechanical vibration or shaking on the triggering mechanism and the NFC sensor 30's information reading, improving the stability and reliability of the transmitter's operation.

[0040] In one embodiment, the bottom of the card holder 40 is further provided with an elastic element.

[0041] Specifically, a suitable spring is selected as the elastic element based on the overall design requirements, space size, and required elastic force of the transmitter. A special mounting structure is designed at the bottom of the card tray 40 to fix the spring. A cylindrical groove can be set at the bottom of the card tray 40, with a diameter slightly larger than the outer diameter of the spring and a depth sufficient to accommodate part of the spring's length in its natural state, ensuring that the spring can be stably mounted on the card tray 40. When the NFC card 150 is inserted into the placement area, the card will squeeze the card tray 40, causing the card tray 40 to move downwards. At this time, the spring is compressed, generating an upward elastic force. As the card continues to be inserted, the spring force gradually increases, eventually fixing the NFC card 150 tightly between the card tray 40 and the baffle 50, ensuring the stability of the card's position within the transmitter and preventing the NFC sensor 30 from affecting the reading of card information due to shaking during gameplay. When the NFC card 150 is removed, the spring is no longer compressed by the card, and its stored elastic potential energy begins to be released. The spring force will push the card tray 40 upward, returning it to its initial position and preparing it for the next insertion of the NFC card 150.

[0042] In other words, the spring's elasticity allows the NFC card 150 to fit snugly between the card holder 40 and the baffle 50, reducing card movement within the transmitter. During gameplay, even if the transmitter experiences slight impacts or vibrations, the card maintains a relatively stable position, ensuring the NFC sensor 30 can accurately read the card's information, improving data reading accuracy and reliability. Furthermore, due to the spring's elasticity and compression stroke, it can accommodate NFC cards 150 of varying thicknesses. Whether the card is of standard thickness or has thickness variations due to manufacturing processes, the spring's elasticity adjusts to securely fix the card in the appropriate position, enhancing the transmitter's versatility. Additionally, the spring's elasticity provides a natural damping feel when inserting and removing the NFC card 150, making operation smoother. When inserting the card, the spring gradually compresses, providing clear feedback to the player that the card is being correctly secured; when removing the card, the spring pushes the card holder 40 back to its original position, facilitating the next operation and improving the user experience. Compared to the card tray 40 without elastic components, the card tray 40 with springs moves more smoothly, reducing operational issues caused by jamming. Players experience a smoother operation when inserting and removing cards, further enhancing player satisfaction with the dispenser.

[0043] In one embodiment, the main control board 20 is also provided with a touch button 60 on the side of the NFC sensor 30. When the NFC card 150 is inserted into the placement area, the card tray 40 presses down to press the touch button 60.

[0044] Specifically, the touch button 60 is connected to the trigger signal processing circuit on the main control board 20. When the touch button 60 is pressed, its internal contacts close, generating an electrical signal. This electrical signal is transmitted to the trigger signal processing circuit on the main control board 20. The trigger signal processing circuit on the main control board 20 filters, amplifies, and shapes the received electrical signal to eliminate interference signals, and then transmits the processed signal to the main control chip. After receiving a valid trigger signal, the main control chip activates the NFC sensor 30 according to a pre-set program, enabling it to start working and prepare to read the information in the NFC card 150.

[0045] In other words, triggering the NFC sensor 30 by directly pressing the touch button 60 via the card tray 40 offers higher physical triggering accuracy compared to other triggering methods based on electronic signal detection. This mechanical triggering method is unaffected by electromagnetic interference; as long as the card tray 40 accurately presses the touch button 60, a trigger signal can be reliably generated, ensuring that the NFC sensor 30 can be activated promptly when needed. Since the touch button 60 requires a certain amount of pressure to be triggered, it will not generate false trigger signals due to slight external vibrations or interference when no NFC card 150 is inserted. This greatly improves the reliability of the triggering mechanism and reduces frequent device startups and energy waste caused by false triggers.

[0046] In one embodiment, the main control board 20 is provided with a color-changing light 70 around the touch button 60, and the housing 10 is provided with a light guide cover 80 corresponding to the color-changing light 70.

[0047] Specifically, the shape and size of the light guide cover 80 are designed based on the installation position of the RGB LED 70 and the structure of the housing 10. The main function of the light guide cover 80 is to uniformly guide the light emitted by the RGB LED 70 to the outside of the housing 10, improving light utilization and display effect. The light guide cover 80 can be made of transparent or semi-transparent materials, such as acrylic or polycarbonate. The design must consider the shape of the light-incident and light-excising surfaces of the light guide cover 80, as well as the internal light-guiding structure, such as prisms and reflective surfaces, to optimize the light propagation path. In the main control chip's program, logic code is written to control the RGB LED 70 to light up. When the NFC sensor 30 is activated, the main control chip detects the corresponding activation signal and then controls the control pins of the RGB LED 70 to simultaneously illuminate it. The lighting color, brightness, and flashing mode of the RGB LED 70 can be set according to actual needs, for example, set to constant light, breathing light effect, or rapid flashing, to provide different prompting functions.

[0048] In other words, when the NFC sensor 30 is activated, the iridescent light 70 illuminates simultaneously, providing players with an intuitive visual cue. Players do not need to rely on other methods (such as checking the device display 100 or listening to audio prompts) to confirm whether the NFC sensor 30 has been activated; they only need to observe the illumination status of the iridescent light 70, improving the convenience and efficiency of operation. Furthermore, the iridescent light 70 can emit multiple colors of light and achieve different flashing effects, creating a unique atmosphere for the transmitter. In games, this atmosphere can increase the fun and immersion, enhancing the player's gaming experience. Additionally, the light guide 80 evenly guides the light from the iridescent light 70 to the outside of the housing 10, giving the transmitter a unique lighting effect. Among many similar devices, this transmitter with the iridescent light 70 is easier for players to identify and remember, improving the device's recognizability and market competitiveness.

[0049] In one embodiment, the side of the housing 10 is further provided with a horn component 90, which is electrically connected to the main control board 20.

[0050] Specifically, when the NFC sensor 30 is activated, the speaker 90 emits a sound effect, providing players with immediate auditory feedback. Combined with the previously mentioned RGB lighting 70, the speaker 90's sound and visual cues combine to create a multi-sensory interactive experience. This multi-sensory experience increases player attention and engagement with the device, enhancing user satisfaction. Furthermore, besides emitting a sound effect when the NFC sensor 30 is activated, more sound effects can be programmed. For example, the speaker 90 can emit different sound effects to indicate whether the NFC card 150 is read successfully or not; in games, corresponding sound effects can be played based on different game scenarios, increasing the game's fun and immersion. Unique sound effects can also become a brand feature of the device. By designing recognizable sound effects, players can associate the sound with the corresponding brand, improving brand awareness and reputation.

[0051] In one embodiment, the main control board 20 is further provided with a Bluetooth module.

[0052] Specifically, by reading the other party's NFC badge through the NFC sensor 30, the Bluetooth MAC address of the other party's transmitter can be obtained, and a Bluetooth connection can be automatically established, allowing both parties to interact and compete. That is, through the Bluetooth module, interaction between the two transmitters can be achieved, and a mobile phone can also be connected to upload data; in addition, a send button 140 is provided on the housing 10 to send the read card information, thus enabling the two-way battle function.

[0053] More specifically, the main control chip's program includes a reading program for the NFC sensor 30. When the NFC sensor 30 detects the insertion or proximity of an NFC badge, it initiates a reading operation. Using the communication protocol between the NFC sensor 30 and the badge, it reads the information stored in the badge, including the other party's transmitter Bluetooth MAC address. After reading the data containing the Bluetooth MAC address, the main control chip parses the data and extracts the valid Bluetooth MAC address. The extracted Bluetooth MAC address is stored in the main control chip's memory, such as EEPROM or Flash memory, for subsequent Bluetooth connection operations. The main control chip's program also includes logic code for automatic Bluetooth connection. Upon successfully obtaining the other party's Bluetooth MAC address, the main control chip controls the Bluetooth module to initiate a connection request. The connection request includes relevant information about the local Bluetooth module, such as the device name and service UUID. During the connection process, the main control chip monitors the Bluetooth connection status in real time. If the connection is successful, a Bluetooth communication link can be established between the two transmitters for data exchange; if the connection fails, the main control chip can retry according to a preset strategy, such as waiting for a period of time before initiating the connection request again, or prompting the player to reposition the NFC badge.

[0054] In addition, develop a mobile application to work with the transmitter. This application needs to have Bluetooth communication capabilities, enabling it to search for and connect to the transmitter's Bluetooth module. Simultaneously, the application should have a user-friendly interface for players, facilitating operation and data viewing. Establish a data upload protocol between the transmitter and the mobile phone, clearly defining the data upload format, content, and transmission timing rules. For example, the transmitter can periodically upload relevant game data (such as scores and operation records) to the mobile application. The mobile application can then parse and store the received data, providing functions such as data statistics, analysis, and sharing.

[0055] Additionally, a send button 140 is designed on the housing 10, and this button is electrically connected to the main control board 20 via a wire. The function code for the send button 140 is written in the main control chip's program. When the player presses the send button 140, the main control chip detects the button press signal, then reads the previously stored card information (including information from the opponent's NFC badge, etc.), encapsulates the read card information according to a predetermined communication protocol, and sends it to the opponent's transmitter via the Bluetooth module, thereby enabling the two-way battle function.

[0056] In other words, by reading the other party's NFC badge through the NFC sensor 30 to obtain the Bluetooth MAC address and automatically connecting via Bluetooth, the connection process between the two transmitters is greatly simplified. Players do not need to manually perform Bluetooth pairing and connection operations; they only need to bring the NFC badge close to the transmitter to quickly establish a connection and enter an interactive competitive state, improving the convenience and smoothness of the game. In addition, the Bluetooth module enables real-time data interaction between the two transmitters, allowing both parties to obtain each other's operation information and game status in a timely manner, making the battle process more intense and exciting, and enhancing the interactivity and competitive experience. Furthermore, the transmitter can connect to a mobile phone and upload data, providing players with richer data management and analysis functions. Players can view their game history, rankings, and other information through a mobile application, and can also share data to social platforms, increasing the device's social attributes. At the same time, developers can analyze the data uploaded by players to understand their usage habits and needs, and optimize and improve the device. In addition, the send button 140 on the casing 10 provides players with a convenient way to send card information. During the battle, players only need to press the send button 140 to send relevant information to the other party; the operation is simple and intuitive, improving the game's operational efficiency and player experience.

[0057] In one embodiment, the housing 10 is further provided with a display screen 100, which is electrically connected to the main control board 20.

[0058] Specifically, the transmitter has multiple NFC sensors 30. To solve the problem of interference between multiple NFC sensing areas, a single-sensor-area triggering method is used for card reading, reading one sensing area at a time when a card is inserted. Because there are multiple NFC sensors 30, card information can be superimposed. Different cards can be inserted, and the card information can be saved to the memory of the main control board 20 for secondary processing, enabling more complex interactive attributes. After the NFC sensor 30 reads the card, the card information is simultaneously displayed on the display screen 100.

[0059] In other words, by adopting a single-sensor zone triggering method, only one sensor zone is read per card insertion, effectively avoiding mutual interference between multiple NFC sensors 30. This ensures the accuracy and stability of each card reading operation, reduces card reading errors or data loss caused by interference, and improves the reliability of the transmitter. Furthermore, players don't need to worry about the confusion caused by multiple sensor zones triggering simultaneously; simply inserting the card into the designated sensor zone completes the reading, making the operation simpler and more intuitive, enhancing the user experience. Additionally, multiple NFC sensors 30 can overlay card information, allowing players to create various effects and strategies by inserting different card combinations. For example, in card battle games, players can choose appropriate cards to overlay based on their opponent's situation and their own tactical needs, increasing the game's strategy and depth. The card information overlay function brings more application scenarios to the transmitter. Besides the gaming field, it can also be applied to education and training. For example, in educational scenarios, different cards can represent different knowledge points or skills; overlaying card information allows for the comprehensive application and expansion of knowledge. Furthermore, after the NFC sensor 30 reads the card, the card information is immediately displayed on the display screen 100, providing players with real-time feedback. Players can immediately understand the card's attributes and effects without needing to obtain information through other means (such as consulting a manual), improving the convenience and efficiency of operation. The intuitive display function of the display screen 100 enhances the interactivity between the player and the transmitter. Players can make corresponding operations and decisions based on the information displayed on the display screen 100, making the entire interaction process smoother and more natural. At the same time, the aesthetically pleasing display interface can also attract the player's attention and increase the player's liking for the device.

[0060] In one embodiment, the housing 10 is further provided with a switch 110, which is electrically connected to the main control board 20, and the switch 110 is provided with multiple buttons.

[0061] Specifically, the multiple buttons on the switch 110 allow players to quickly switch between different functions of the transmitter through simple button operations, improving the device's efficiency. This is especially suitable for scenarios requiring frequent function switching, such as quickly switching between different game modes or settings during gameplay. Furthermore, by using the switch 110 to switch between different functions, the transmitter can integrate more features to meet diverse player needs. For example, in addition to basic NFC sensing functionality, it can also integrate game mode, settings mode, Bluetooth connection mode, etc., making the transmitter a feature-rich, multi-functional device.

[0062] In one embodiment, the bottom of the housing 10 is also provided with a wristband 120.

[0063] Specifically, the appropriate wristband type should be selected based on the launcher's usage scenario, target player group, and budget. Common wristband types include Velcro wristbands, buckle wristbands, and elastic wristbands. Velcro wristbands are easy to adjust and suitable for players with different wrist sizes; buckle wristbands have a sturdy structure and a more traditional appearance; elastic wristbands offer better fit and comfort, automatically adapting to wrist size.

[0064] In other words, by wearing the transmitter on the wristband 120, players no longer need to hold the transmitter in their hands, thus freeing up their hands and making it convenient to carry the transmitter while engaging in other activities. For example, in outdoor sports or interactive games, players can move their hands freely without worrying about the placement and carrying of the transmitter. Furthermore, the wristband 120 secures the transmitter to the wrist, reducing the risk of loss. Compared to keeping the transmitter in a pocket or bag, wearing it on the wrist is more intuitive and secure, allowing players to be aware of its presence at all times. Additionally, the transmitter worn on the wrist is more stable during operation. Players can control the direction and angle of the transmitter through natural wrist movements, reducing operational errors caused by unstable hand grip. For example, when performing NFC card sensing or Bluetooth connection operations, the stable wearing method improves the accuracy and success rate of the operation. Since the transmitter is always near the player's wrist, players can operate quickly and easily without having to search for and pick it up when needed, improving the response speed and efficiency of the operation.

[0065] In one embodiment, the housing 10 is further provided with a rechargeable battery 130, which is electrically connected to the main control board 20 to power the entire transmitter.

[0066] Specifically, the use of the rechargeable battery 130 allows the transmitter to operate without an external power cord, enabling users to use it anytime, anywhere, without being limited by the location of power outlets. Whether in outdoor activities, gaming parties, or mobile work scenarios, the transmitter is conveniently portable and easy to use, greatly improving the device's portability. Compared to transmitters using disposable batteries 130, the rechargeable battery 130 reduces the number of spare batteries users need to carry, lightening their burden. Users only need to carry one charger to charge the transmitter, making it convenient and environmentally friendly.

[0067] In one embodiment, the housing 10 is composed of an upper housing 11 and a lower housing 12 connected together. The card tray 40, baffle 50, light guide cover 80, speaker 90, display screen 100, switch 110 and send button 140 are disposed on the upper housing 11, and the battery 130 and wristband 120 are disposed on the lower housing 12.

[0068] Specifically, different components are installed on the upper shell 11 and the lower shell 12 respectively, realizing the modular design of the transmitter. During assembly, the components on the upper shell 11 and the lower shell 12 can be installed and debugged separately before connecting them together, improving assembly efficiency. At the same time, when the transmitter malfunctions, the upper shell 11 and the lower shell 12 can be easily disassembled to repair or replace the corresponding components, reducing maintenance costs and difficulty. In addition, the card tray 40, baffle 50, light guide cover 80, speaker 90, display screen 100, switch 110 and transmit button 140, and other operation and display-related components are located on the upper shell 11 for easy operation and observation by the player; while the battery 130 and wrist strap 120, which are larger or require special installation, are located on the lower shell 12, making the overall structure of the transmitter more reasonable and easier to assemble and maintain.

[0069] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
