Settlement Token Generation for Privilege Granting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing code settlement systems using 2D barcodes, such as QR codes, often fail to grant privileges, like discounts, during the purchase of specific commodities.
Innovation Solution
A method and device that acquire a user identifier and application information for granting privileges upon purchase, generate a settlement token, and transmit it to a user terminal, allowing the system to recognize and apply privileges when specific commodities are purchased, enabling privilege granting at the time of settlement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If code settlement using 2D barcodes is implemented, then settlement efficiency is improved, but privilege granting capability is lost
Solution Approach 1:
The patent merges the settlement code generation function with the privilege granting function into a single integrated system. The server combines user identification, application information verification, and settlement code generation into one unified process, allowing both settlement efficiency and privilege granting capability to coexist.
Solution Approach 2:
The settlement code generated by the patent serves multiple functions simultaneously: it acts as both a payment settlement identifier and a privilege granting key. The code contains embedded information that enables both transaction completion and automatic privilege application, making the system multi-functional.
2Ease of operation
If simple code settlement is used, then ease of operation is improved, but ability to recognize target commodities is worsened
Solution Approach 1:
The patent creates a comprehensive settlement code that copies and encodes multiple pieces of information including user identification, commodity information, and application details into a single data structure. This allows the simple act of scanning the code to retrieve all necessary information for both settlement and privilege verification.
Solution Approach 2:
The settlement code is designed as a nested data structure where multiple layers of information are embedded within each other. The code contains user ID, which links to application information, which in turn contains commodity-specific privilege data, creating a nested information hierarchy that maintains simplicity while preserving detailed commodity identification.

AI summary
A settlement device includes an application reception unit that associates and stores a user ID for specifying a user and application information indicating an application to grant a privilege at the time of purchase of a target commodity in a storage unit when the user ID and the application information are acquired, a token generation unit that generates a settlement token and transmits the settlement token to a user terminal when a request for acquiring the user ID and a settlement code is received from a user terminal, a settlement information reception unit that is configured to receive the settlement information used to perform settlement of commodities, the settlement token, and privilege target commodity information for specifying a commodity which is a privilege target from a store terminal that is configured to read the settlement code according to the settlement token, and a privilege granting unit that is configured to grant the privilege corresponding to application information to the user when the application information associated with the user ID corresponding to the received settlement token corresponds to the received privilege target commodity information.
