Description

Technical Field

[0001] This invention relates to the field of electronic payment technology, and more specifically to a rapid input system for consumer information and electronic receipts for physical stores. Background Technology

[0002] In the brick-and-mortar retail industry, the collection of consumer information and the delivery of receipts are two crucial aspects of store operations and management. In the traditional model, physical stores typically collect consumer information by cashiers asking customers if they want a membership card during manual checkout and then manually entering the information through manual input or card swiping. Alternatively, customers may be guided to fill out a paper membership application form or register via a separate mini-program or app. Receipts are generally delivered by printing paper receipts. Therefore, the existing technologies described above still have the following shortcomings: The separation of consumer information collection and electronic receipt delivery means that information cannot be reused, leading to duplicate data entry and wasted efficiency. Each transaction generates an independent electronic receipt QR code, requiring consumers to scan the code separately, which prolongs the settlement time. The lack of dynamic adaptation capabilities and the use of fixed information collection templates result in information redundancy or insufficiency. Summary of the Invention

[0003] In order to overcome the above-mentioned defects of the prior art, the embodiments of the present invention provide a rapid input system for consumer information and electronic receipts for physical stores, so as to solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a rapid input system for consumer information and electronic receipts for physical stores, comprising a transaction unit, an aggregation code unit, a display unit, a scanning unit, a parsing unit, a data entry unit, a receipt unit, a cloud unit, and a database. The transaction unit generates current transaction data; the aggregation code unit generates a smart aggregation code using the transaction data; the display unit displays the smart aggregation code generated by the aggregation code unit on the physical store's POS terminal; the scanning unit scans the aggregation code displayed by the display unit; and the parsing unit parses the aggregation code scanned by the scanning unit and, based on the parsing result, queries the cloud unit or database for the consumer identity associated with the transaction. The system determines the authentication status of a consumer. If the status is unverified, the data entry unit is activated; if the status is verified, the receipt unit is activated. When the data entry unit is activated, it provides a visual information entry interface, collects the consumer's identity information, and forms a consumer profile. When the receipt unit is activated, it automatically receives and displays the electronic receipt associated with the current transaction. The cloud unit receives the consumer's identity information generated by the data entry unit, as well as the identity information and transaction association information after data entry. The cloud unit stores and manages the consumer's identity information and historical consumption records, and generates an electronic receipt containing the current transaction consumption information and the consumer's identity information. The database is used to store the data within the cloud unit and to access information entry templates via the internet.

[0005] In a preferred embodiment, the transaction unit, the aggregation code unit, and the display unit are combined to form a POS terminal, which is deployed on a physical store's cashier terminal. The scanning unit, the parsing unit, and the filling unit are combined to form a mobile consumer terminal, which is deployed on a mobile terminal device. The receipt unit, the cloud unit, and the database are integrated in a cloud server. The receipt unit communicates with the mobile consumer terminal through the cloud, so that the electronic receipt is displayed on the mobile consumer terminal.

[0006] In a preferred embodiment, the smart aggregated code generated by the aggregated code unit is either a dynamic QR code or a dynamic barcode. When the parsing unit performs parsing, it decodes the scanned smart aggregated code, extracts the transaction identifier code contained in the code, and queries the cloud unit for the consumer identity authentication status corresponding to the transaction identifier code. If a consumer identity is found to be associated with the transaction, it is determined to be in an authenticated state; if no consumer identity is found to be associated with the transaction, it is determined to be in an unauthenticated state.

[0007] In a preferred embodiment, when the filling unit provides an information filling interface, it extracts the store type identifier and marketing scenario parameters carried in the aggregation code, and the filling unit obtains the corresponding information collection template from the database. The information collection template supports visual configuration, and physical store managers can set the list of information dimensions to be collected for different store types and different marketing scenarios. The information dimensions include at least one of mobile phone number, birthday, gender, residential area and consumption preference tags, and dynamically generate a personalized information filling interface.

[0008] In a preferred embodiment, the consumer profile formed after the filling unit completes the form supports multi-terminal association. Multiple mobile terminals of the same consumer can share the same consumer profile and electronic receipt history list without repeated binding.

[0009] In a preferred embodiment, the cloud unit generates a consumer profile and a consumer behavior analysis report from the consumer profiles and corresponding electronic receipt data filled in by the reporting unit, and the cloud unit sends the analysis results to the database for storage, and the analysis results can be retrieved at any time.

[0010] In a preferred embodiment, the transaction unit needs to perform payment detection when generating transaction data. During payment detection, the completion status of the payment operation is detected. The transaction unit only provides transaction data when the payment operation is completed. The aggregation code unit only generates and displays the smart aggregation code when it receives the transaction data.

[0011] In a preferred embodiment, after the receipt unit generates an electronic receipt, it stores the electronic receipt in a database. The database establishes an association index between the electronic receipt and the consumer profile filled in by the reporting unit in the form of structured data. Consumers can view the historical list of the electronic receipt through any associated mobile terminal without having to scan the code repeatedly.

[0012] In a preferred embodiment, the aggregation code unit includes an embedded IoT device deployed in the cashier area of ​​a physical store. The embedded IoT device includes a Bluetooth module and an NFC module. The consumer mobile terminal can communicate with the embedded IoT device via Bluetooth or NFC to replace the QR code scanning method to complete consumer information identification and electronic receipt transmission.

[0013] In a preferred embodiment, the aggregation code unit provides an effective duration T when providing the aggregation code. The aggregation code provided by the aggregation code unit becomes invalid if the effective duration T is exceeded. The formula for calculating the effective duration T is as follows: In the formula, JC is the preset basic validity period, k is the time coefficient for each retry, N is the number of attempts to scan the aggregate code but fail to complete information collection or receipt retrieval, and the actual expiration time of the aggregate code is the payment completion time plus the validity period T. After the aggregate code has been scanned 5 times and still fails to complete information collection or receipt retrieval, the aggregate code unit regenerates the aggregate code.

[0014] The technical effects and advantages of this invention are as follows: 1. This invention generates intelligent aggregate codes by setting up an aggregate code unit and links the filling unit and the receipt unit together, so that consumers can complete identity verification, information supplementation or electronic receipt acquisition by scanning the code once, avoiding repeated information entry. The cloud unit associates consumer profiles with transaction data, and authenticated users do not need to fill in information again, realizing the sharing and reuse of information between the two stages of information collection and electronic receipt delivery, and improving settlement efficiency. 2. This invention combines the information collection and receipt acquisition after payment into a single operation through intelligent aggregation code. Consumers do not need to perform additional scanning actions to obtain electronic receipts, reducing the interactive steps in the settlement process. The aggregation code unit only generates a dynamic aggregation code after payment, avoiding the generation and scanning of invalid codes, further shortening the consumer's waiting time and improving the passage efficiency of the checkout channel. 3. When filling out the form, this invention can dynamically obtain information collection templates from the database and generate personalized information filling interfaces in real time based on the store type identifier and marketing scenario parameters carried in the aggregation code. Physical store managers can freely configure the required information dimensions to adapt to the needs of different store types and marketing activities. This avoids information redundancy caused by fixed forms and ensures the complete collection of key information, improving the flexibility and accuracy of consumer information collection.

[0015] Figure 1 This is a schematic diagram of the overall system composition of the present invention.

[0016] Figure 2 This is a schematic diagram of the integrated structure of the present invention. Detailed Implementation

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The consumer information and electronic receipt rapid entry system for physical stores involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Reference Figure 1 This invention provides a rapid consumer information and electronic receipt entry system for physical stores, including a transaction unit, an aggregation code unit, a display unit, a scanning unit, a parsing unit, a data entry unit, a receipt unit, a cloud unit, and a database. The transaction unit generates current transaction data. The aggregation code unit uses the transaction data to generate a smart aggregation code, which integrates a consumer information entry point and an electronic receipt retrieval point. The display unit displays the smart aggregation code generated by the aggregation code unit on the physical store's POS terminal. The scanning unit scans the aggregation code displayed by the display unit. The parsing unit parses the aggregation code scanned by the scanning unit and queries the cloud unit or database for the transaction details based on the parsing result. The system determines the consumer's identity authentication status. If the status is unverified, the data entry unit is activated; if the status is verified, the receipt unit is activated. When the data entry unit is activated, it provides a visual information entry interface, collects the consumer's identity information, and forms a consumer profile. When the receipt unit is activated, it automatically receives and displays the electronic receipt associated with the current transaction. The cloud unit receives the consumer's identity information generated by the data entry unit, as well as the identity information and transaction association information after data entry. The cloud unit stores and manages the consumer's identity information and historical consumption records, and generates an electronic receipt containing the current transaction consumption information and the consumer's identity information. The database is used to store the data within the cloud unit and to access information entry templates via the internet.

[0019] In this embodiment, the application integrates consumer information collection with electronic receipt delivery by setting up a transaction unit, an aggregation code unit, a display unit, a scanning unit, a parsing unit, a filling unit, a receipt unit, a cloud unit, and a database. The parsing unit determines whether to activate the filling unit or the receipt unit based on the query results. During the first consumption, unauthenticated users complete information entry through the filling unit to form a file. During subsequent consumption, the system directly recognizes the user as an authenticated user and automatically provides an electronic receipt. This solution avoids repeated information collection, reduces the interaction steps in the settlement process, and thus improves checkout efficiency.

[0020] Reference Figure 2 The transaction unit, aggregation code unit, and display unit are combined to form a POS terminal, which is deployed on the physical store's cashier terminal. The scanning unit, parsing unit, and data entry unit are combined to form a mobile consumer terminal, which is deployed on a mobile terminal device. The receipt unit, cloud unit, and database are integrated in a cloud server. The receipt unit communicates with the mobile consumer terminal through the cloud to display the electronic receipt on the mobile consumer terminal.

[0021] In this embodiment, the system is divided into a POS terminal, a mobile terminal for consumers, and a cloud server. The electronic receipt unit communicates with the mobile terminal for consumers via the cloud to display the electronic receipt. With this layered architecture, the POS terminal only needs to generate and display the aggregate code, without storing consumer profiles. The mobile terminal for consumers is responsible for scanning the code and filling in the information. The cloud centrally manages the data and distributes the electronic receipts. This architecture reduces the hardware requirements of physical store terminals, facilitates multi-store deployment, and ensures the synchronous display of electronic receipts across multiple consumer terminals.

[0022] Reference Figure 1 The smart aggregated code generated by the aggregated code unit is either a dynamic QR code or a dynamic barcode. When the parsing unit parses the smart aggregated code obtained by scanning, it decodes the smart aggregated code, extracts the transaction identifier code contained in the code, and queries the cloud unit for the consumer identity authentication status corresponding to the transaction identifier code. If a consumer identity is found to be associated with the transaction, it is determined to be in an authenticated state. If no consumer identity is found to be associated with the transaction, it is determined to be in an unauthenticated state.

[0023] In this embodiment, the aggregated code generated by this application is a dynamic QR code or a dynamic barcode. The parsing unit queries the identity authentication status from the cloud by extracting the transaction identifier code. The timeliness of the dynamic code can prevent replay attacks and improve transaction security. By querying the authentication status from the cloud, consumers do not need to carry a physical membership card and can complete identity recognition simply by scanning the code, providing reliable data for subsequent contactless information filling or quick receipt acquisition.

[0024] Reference Figure 1 When the filling unit provides an information filling interface, it extracts the store type identifier and marketing scenario parameters carried in the aggregation code. The filling unit also obtains the corresponding information collection template from the database. This information collection template supports visual configuration. Physical store managers can set the list of information dimensions to be collected for different store types and different marketing scenarios. These information dimensions include at least one of mobile phone number, birthday, gender, residential area, and consumption preference tags. The filling unit dynamically generates a personalized information filling interface. The consumer profile formed after the filling unit completes the filling supports multi-terminal association. Multiple mobile terminals of the same consumer share the same consumer profile and electronic receipt history list without repeated binding.

[0025] In this embodiment, the data entry unit can extract store type identifiers and marketing scenario parameters, and dynamically obtain corresponding information collection templates from the database. It supports visual configuration, allowing different stores and different marketing activities to flexibly configure the required information dimensions, avoiding information redundancy or missing key information caused by traditional fixed forms, and improving the accuracy and adaptability of consumer information collection. The consumer profile of this application supports multi-terminal association, and multiple mobile terminals of the same consumer share the same profile and electronic receipt history list, thereby allowing consumers to seamlessly access their consumption records and electronic receipts on multiple devices such as mobile phones and tablets without having to repeatedly bind or fill in information, improving user experience, and ensuring the consistency of consumer profile data.

[0026] The specific process for setting up the template in this application is as follows: Physical store managers can enter the information collection template interface. The upper part of the interface is a tree structure of store types, including pre-set store type nodes such as "supermarket", "clothing store", "beauty store", "restaurant", and "convenience store". The center of the interface is the information collection field area, which contains a library of predefined field templates that can be added. Predefined fields include name, gender, mobile phone number, birthday, city of residence, consumption preferences, etc. Each field has a switch button. Managers can select the information fields to be collected according to the store's operational needs. There is a preview window at the bottom of the interface to preview the layout of the information filling interface presented to consumers in real time. After completing the configuration, the manager saves the template, and the system associates the template with the specified store type and marketing scenario. When a consumer makes their first purchase at an affiliated store, the template is dynamically retrieved through the data entry unit, generating a corresponding information entry interface. After the consumer fills in the relevant information as prompted on the interface, the information is stored in the consumer profile. When the same consumer makes subsequent purchases at different types of stores, only the information dimensions that have not been entered before can be collected based on the information collection template of that store, gradually improving the consumer profile without requiring the consumer to repeatedly fill in the basic information that has already been entered.

[0027] Reference Figure 1 The cloud unit generates a consumer profile and a consumer behavior analysis report from the consumer profiles and corresponding electronic receipt data filled in by the reporting unit, and sends the analysis results to the database for storage. The analysis results can be retrieved at any time.

[0028] In this embodiment, the cloud unit of this application uses consumer profiles and electronic receipt data to generate consumer profiles and consumer behavior analysis reports, which are stored in a database for easy retrieval. This application has data value-added capabilities, and physical stores can use the analysis reports to achieve precise marketing, personalized recommendations, and customer lifecycle management, thereby enhancing the commercial value of this application.

[0029] Reference Figure 1The transaction unit needs to perform payment detection when generating transaction data. During payment detection, the completion status of the payment operation is checked. The transaction unit only provides transaction data when the payment operation is completed. The aggregation code unit only generates and displays the smart aggregation code when it receives transaction data.

[0030] In this embodiment, the transaction unit is restricted to providing transaction data only after payment is completed. The aggregation code unit generates and displays the smart aggregation code only when it receives transaction data, ensuring that the aggregation code is only generated after valid payment, avoiding the generation of invalid codes and mis-scanning, reducing the invalid load on network resources and cash register terminals, and also preventing consumers from accidentally operating the information collection process when they have not paid.

[0031] Reference Figure 1 After generating an electronic receipt, the receipt unit stores the electronic receipt in a database. The database establishes an association index between the electronic receipt and the consumer profile filled in by the reporting unit in the form of structured data. Consumers can view the historical list of the electronic receipt through any associated mobile terminal without having to scan the code repeatedly.

[0032] In this embodiment of the application, when storing electronic receipts in the cloud, the electronic receipts are linked to the consumer profile in the form of structured data. Consumers can view the historical list through any linked mobile terminal without having to scan the code repeatedly. This enables permanent storage and cross-terminal retrieval of electronic receipts, solving the problems of paper receipts being easily lost and difficult to find. At the same time, the elimination of the need for repeated scanning further reduces the operational cost for consumers to obtain historical receipts.

[0033] Reference Figure 1 The aggregation code unit includes an embedded IoT device, which is deployed in the cashier area of ​​a physical store. The embedded IoT device includes a Bluetooth module and an NFC module. The consumer mobile terminal can communicate with the embedded IoT device via Bluetooth or NFC to replace the QR code scanning method to complete consumer information identification and electronic receipt transmission.

[0034] In this embodiment, the aggregated code unit includes an embedded IoT device. Consumer mobile devices can use Bluetooth or NFC to replace QR code scanning to complete information identification and electronic ticket transmission. This application provides alternative communication methods in environments with poor network signals or difficulty in scanning, making the application more applicable. Near-field communication via Bluetooth or NFC can reduce ambient light interference and scanning alignment time, further improving interaction speed and reliability.

[0035] Reference Figure 1 The aggregation code unit provides an aggregation code with a valid duration T. The aggregation code provided by the aggregation code unit becomes invalid if the valid duration T is exceeded. The formula for calculating the valid duration T is as follows: In the formula, JC is the preset basic validity period, k is the time coefficient for each retry, N is the number of attempts to scan the aggregate code but fail to complete information collection or receipt retrieval, and the actual expiration time of the aggregate code is the payment completion time plus the validity period T. After the aggregate code has been scanned 5 times and still fails to complete information collection or receipt retrieval, the aggregate code unit regenerates the aggregate code.

[0036] In this embodiment of the application, the formula for calculating the effective duration T is as follows: Furthermore, this application sets up a mechanism to regenerate the aggregation code after 5 failures. The dynamic validity period mechanism of this application adaptively extends the validity period based on the number of retries, avoiding premature expiration of the aggregation code due to network fluctuations or slow user operation. At the same time, a maximum number of retries is set before regenerating the code to prevent infinite retries from consuming system resources. This application can balance security and user experience, ensuring the timeliness of the aggregation code while providing users with reasonable fault tolerance.
