Description

Application wake-up method based on NFC tags and NFC acceptance terminal

[0001] This application claims priority to Chinese Patent Application 202411921260.2, filed on December 24, 2024, entitled “Application Wake-up Method and NFC Acceptance Terminal Based on NFC Tag”, the entire disclosure of which is incorporated herein by reference. Technical Field

[0002] This invention relates to NFC tag technology, specifically to an application wake-up method based on NFC tags and an NFC acceptance terminal. Background Technology

[0003] With the widespread application of Near Field Communication (NFC) technology, NFC tags are highly favored for their convenience and security. Existing NFC tag technology allows the storage of multiple application-type or URL-type records within a single tag. These records typically contain information pointing to different applications, such as application package names and URLs. However, when a mobile terminal reads such an NFC tag, its processing mechanism often only selects one record to respond to. Typically, the system decides which application to activate based on preset logic (e.g., selecting the record with the longest package name), ignoring all other application records that may exist in the tag.

[0004] In other words, existing NFC tags cannot wake up multiple applications on a mobile terminal, or users need to scan different NFC tags multiple times to launch multiple applications. These issues directly hinder multiple payment institutions or service providers from jointly conducting NFC-based payment business at the same merchant, reducing user experience and efficiency.

[0005] On the other hand, to achieve automatic wake-up of multiple application records in NFC tags, theoretically, it would require significant modifications to the user's mobile terminal operating system or NFC tag processing flow. This would not only involve substantial technical research and development and testing costs, but also, in the absence of clear commercial incentives, mobile terminal manufacturers often lack the motivation to make such modifications. Summary of the Invention

However, those skilled in the art will readily recognize that the same principles are equivalently applicable to all types of NFC tag-based multi-application wake-up systems and NFC tag acceptors, and that these same principles can be implemented therein, and that any such variations do not depart from the true spirit and scope of this patent application.

[0056] Furthermore, reference is made in the following description to the accompanying drawings, which illustrate specific exemplary embodiments. Electrical, mechanical, logical, and structural modifications may be made to these embodiments without departing from the spirit and scope of the invention. Moreover, while features of the invention are disclosed in conjunction with only one of several embodiments, this feature may be combined with one or more other features of other embodiments if desired and / or advantageous for any given or identifiable function. Therefore, the following description should not be considered limiting in any sense, and the scope of the invention is defined by the appended claims and their equivalents.

[0057] Terms such as “possessing” and “comprising” indicate that, in addition to having units (modules) and steps that are directly and explicitly stated in the specification and claims, the technical solution of the present invention does not exclude the presence of other units (modules) and steps that are not directly or explicitly stated.

[0058] The technical concept of the NFC tag-based application wake-up method of the present invention is to realize the automatic invocation of multiple applications on the mobile terminal by combining the posture recognition of the mobile terminal and the dynamic writing of the NFC tag. Specifically, the NFC receiving terminal wakes up and invokes different applications by recognizing the different proximity postures of the mobile terminal, thereby enabling the wake-up and invocation of multiple applications on one NFC receiving terminal.

[0059] The main implementation of the NFC tag-based application wake-up method of the present invention is that the NFC receiving terminal identifies the proximity posture of the mobile terminal through its camera, and selects the application package name and service parameters corresponding to the proximity posture and dynamically writes them into the NFC tag, thereby waking up the corresponding application in the mobile terminal to start service processing through the NFC mechanism.

[0060] Figure 1 is a schematic diagram of the structure of an NFC acceptance terminal according to an embodiment of the present invention.

[0061] As shown in Figure 1, the NFC acceptance terminal 100 includes:

[0062] NFC tag module 110 is used to support NFC tags in read and write modes, wherein the NFC tag has composite records that support application type and other types (depending on the business parameter type, such as selecting URL type record if the business parameter is a URL address, or selecting Bluetooth type record if the business parameter is a Bluetooth address).

[0063] Camera 120 is used to acquire a series of posture images when the mobile terminal approaches the NFC acceptance terminal 100;

[0064] The posture recognition module 130 pre-sets and stores the correspondence between different proximity postures of the mobile terminal and application package names and service parameters. It uses a specified algorithm to analyze the posture images acquired by the camera 120 and recognize the posture of the mobile terminal. Based on the recognized proximity posture, it finds the application package name and service parameters corresponding to the proximity posture from the correspondence and writes the corresponding application package name and service parameters into the NFC tag provided by the NFC tag module 110.

[0065] Next, a specific embodiment of the NFC tag-based application wake-up method of the present invention will be described.

[0066] In this embodiment, as an example, the mobile terminal can support three applications: application 1, application 2 and application 3, which correspond to approach postures 1, 2 and 3 respectively. The correspondence between postures 1 to 3 and the application package names and service parameters of applications 1 to 3 is pre-set and stored in the posture recognition module 130.

[0067] The application wake-up method based on NFC tags of this embodiment will be described below with reference to Figure 1.

[0068] As shown in Figure 1, the application wake-up method based on NFC tags in this embodiment includes the following steps:

[0069] S100: When the application wake-up method is enabled, the camera 120 of the NFC receiving terminal is turned on. At this time, the user brings his mobile terminal close to the NFC receiving terminal in a certain posture.

[0070] S200: The camera 120 of the NFC receiving terminal captures a series of consecutive posture images of the mobile terminal and sends this series of posture images to the posture recognition module 130.

[0071] S300: The posture recognition module 130 analyzes the received posture image and identifies whether the approach posture of the mobile terminal is posture 1, posture 2 or posture 3. If it is posture 1, the application package name 1 and the corresponding service parameters are selected for posture 1. If it is posture 2, the application package name 2 and the corresponding service parameters are selected for posture 2. If it is posture 3, the application package name 3 and the corresponding service parameters are selected for posture 3.

[0072] S400: The gesture recognition module 130 writes the selected application package name and service parameters into the NFC tag. Specifically, the application package name and service parameters are written into the NFC tag record provided by the NFC tag module 110 as application record and the record type corresponding to the service parameter, respectively.

[0073] S500: The mobile terminal reads the NFC tag to obtain the application package name and service parameters;

[0074] S600: The mobile terminal automatically wakes up the application corresponding to the application package name based on the application package name. The application obtains the corresponding business parameters and completes subsequent processing according to the business process.

[0075] As an example, postures 1 to 3 can be the following proximity postures of the mobile terminal: the mobile terminal is in a horizontal posture relative to the NFC receiving terminal, the mobile terminal is in a vertical posture relative to the NFC receiving terminal, and the mobile terminal is in an oblique posture relative to the NFC receiving terminal.

[0076] To more clearly illustrate the NFC acceptance device and the application wake-up method based on NFC tags of the present invention, another embodiment will be described below.

[0077] Figure 2 is a flowchart illustrating another embodiment of the application wake-up method based on NFC tags according to the present invention.

[0078] In this embodiment, a QR code payment system that simultaneously supports Application 1 (e.g., Alipay) and Application 2 (e.g., UnionPay) is used as an example. The posture recognition module pre-sets and stores a correspondence between the mobile terminal's vertical posture and Application 1, and its horizontal posture and Application 2. The business parameter is a URL address, and the mobile terminal is an Android mobile terminal. An NFC acceptance terminal and a merchant information management system are set up on the merchant side. The NFC acceptance terminal includes a camera, a posture recognition module, an NFC tag module (shown in Figure 2 as the NFC tag it provides), and a code acceptance module.

[0079] As shown in Figure 2, an application wake-up method based on an NFC tag according to an embodiment of the present invention includes the following process:

[0080] S1: After scanning the relevant products, the cashier enters the amount in the merchant information management system and clicks QR code payment (scanned payment);

[0081] S2: The merchant information management system sends a request to the NFC acceptance terminal to obtain the payment code;

[0082] S3: The NFC receiving terminal opens its camera according to the request and waits for the user's mobile terminal to approach the NFC receiving terminal;

[0083] S4: When a user wants to make a payment using the QR code in Application 2, first ensure that the NFC function of the mobile terminal is turned on, and then bring the mobile terminal vertically close to the NFC tag area of ​​the NFC acceptance terminal.

[0084] S5: The camera of the NFC receiving terminal takes a series of multiple posture images when the mobile terminal approaches and sends them to the posture recognition module.

[0085] S6: The posture recognition module performs image recognition on the received multiple posture images and identifies that the mobile terminal is in a vertical posture. Based on the pre-stored correspondence, it knows that the user wants to use application 2 to make a payment.

[0086] S7: The gesture recognition module writes the application package name and payment code application URL of application 2 to the NFC tag;

[0087] S8: The gesture recognition module records the application package name (e.g., com.unionpay) as an application type and writes it into the NFC tag provided by the NFC tag module, and writes the payment code application URL address of application 2 (e.g., https: / / www.unionpay.com / qrcode) as a URL record type into the NFC tag;

[0088] S9: The gesture recognition module sends the payment code query URL address of application 2 (which can be the same as the payment code application address, for example, https: / / www.unionpay.com / qrcode) to the code acceptance module;

[0089] S10: The code acceptance module queries the payment backend for the payment code query URL address to obtain the user's payment code;

[0090] S11: After S7 above, the mobile terminal reads the application type record and URL record of the NFC tag;

[0091] S12: If the application type record read by the mobile terminal is the application package name of application 2 (e.g., com.unionpay), then the application with the package name com.unionpay on the mobile terminal, i.e., application 2, will be invoked according to the application package name.

[0092] S13: Application 2 of the mobile terminal reads the URL record in the NFC tag in NFC read mode and obtains the payment code application URL address;

[0093] S14: Application 2 on the mobile terminal accesses the payment code application URL and requests the generation of a payment code from the payment backend of Application 2;

[0094] S15: The payment backend generates a payment code;

[0095] S16: The code acceptance module obtains the payment code generated by the payment backend;

[0096] S17: The NFC acceptance terminal returns the payment code to the merchant information management system;

[0097] S18: The merchant information management system receives the payment code, generates a merchant order, and sends a scanned payment request to the acquiring institution's backend.

[0098] S19: If the acquiring institution's backend parses the QR code in the scanned payment request and finds that it is the payment code of application 2, then it sends the scanned payment request to the payment backend of application 2.

[0099] S20: The payment backend of application 2 accepts the scanned payment request, returns the transaction result to the acquiring institution's backend, and synchronously notifies application 2 on the mobile terminal of the transaction result;

[0100] S21: The acquiring institution's back-end system will notify the merchant information management system of the received transaction results to complete the transaction.

[0101] Figure 3 is a structural schematic diagram of an NFC acceptance terminal according to another embodiment of the present invention.

[0102] As shown in Figure 3, the NFC acceptance terminal 300 according to another embodiment of the present invention includes:

[0103] NFC tag module 310 is used to provide NFC tags that support read and write operations;

[0104] Camera 320 is used to acquire a gesture image of a mobile terminal that is close to the NFC acceptance terminal;

[0105] The posture recognition module 330 is used to identify the proximity posture of the mobile terminal to the NFC acceptance terminal based on the posture image acquired by the camera, and to look up the application configuration information of the application corresponding to the proximity posture in a correspondence table, and write the application configuration information into the NFC tag provided by the NFC tag module. The correspondence table stores a one-to-one correspondence between multiple proximity postures of the mobile terminal to the NFC acceptance terminal and the application configuration information of multiple applications. The application configuration information includes: application package name and service parameters (in this embodiment, the service parameters are URL addresses); and

[0106] The code acceptance module 340 is used to trigger the camera 310 to open based on the "request to obtain payment code" from the outside and to perform corresponding business processing based on the business parameters from the posture recognition module 330.

[0107] In this embodiment, the posture recognition module 330 pre-sets and stores a correspondence table such that the vertical posture of the mobile terminal corresponds to application 1 and the horizontal posture corresponds to application 2.

[0108] In this embodiment, the NFC tag has a composite record of a first type of record and a second type of record. The posture recognition module 330 writes the application package name and service parameters into the NFC tag as the first type of record and the second type of record, respectively.

[0109] In this embodiment, the first type of record is an application type record, and the second type of record is a URL address. The code acceptance module 340 obtains the payment code by continuously querying and accessing the URL address.

[0110] As described above, the NFC tag-based application wake-up method and NFC acceptance terminal according to the present invention can bring the following technical effects:

[0111] Without modifying the mobile terminal, it is possible to automatically launch multiple applications on the mobile terminal on an NFC acceptance terminal that uses NFC tags as the acceptance method, which can solve the problem that a single NFC acceptance terminal cannot be compatible with different applications of multiple payment institutions at the same time in the existing technology.

[0112] This enhances the user experience. Users simply need to bring their mobile device close to the NFC terminal in a specific posture to automatically wake up and launch the corresponding application, eliminating the need for manual application searching and opening. Furthermore, by recognizing different proximity postures to wake up different applications, it meets users' personalized needs in various scenarios, increasing the flexibility and enjoyment of use.

[0113] The NFC tag-based application wake-up method of the present invention is not limited to payment scenarios, but can also be applied to other application scenarios, such as smart homes, smart offices, smart retail and other fields. By combining gesture recognition and dynamic writing of NFC tags, it can achieve more intelligent and convenient device control and information interaction.

[0114] As described above, the NFC tag-based application wake-up method and NFC acceptance terminal of the present invention can realize more compatible NFC tap-to-pay. Therefore, the NFC tag-based application wake-up method and NFC acceptance terminal of the present invention can be applied to banks, acquiring institutions, internet payment institutions, third-party acquiring institutions, card organizations, terminal manufacturers, etc., and can realize the simultaneous compatibility of different payment applications of multiple payment institutions using one NFC acceptance terminal.

[0115] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Those skilled in the art can conceive of other feasible variations or substitutions based on the technical scope disclosed in this application, and such variations or substitutions are all covered within the scope of protection of this application.
