Location-Verified NFT Issuance for Event Visit Confirmation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems cannot accurately determine if users have visited an event or facility, leading to the potential issuance of tokens to users who have not actually been present.
Innovation Solution
An NFT issuance system that utilizes an information coordination device to acquire location information from user terminals, determining if the user is within a predetermined range of the target area before granting an NFT to the user's wallet address on a blockchain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If location information is acquired from user terminals to determine visitation, then the ability to grant tokens to users is improved, but the accuracy of determining actual visitation deteriorates
Solution Approach 1:
The patent introduces an information coordination device as an intermediary between the user terminal and the NFT issuance device. This mediator acquires location information from the user terminal and relays it to the issuance system, enabling the grant of tokens while maintaining a clear separation of functions. The intermediary helps resolve the contradiction by providing a trusted channel for location verification without requiring direct access to the user's terminal data.
Solution Approach 2:
The patent replaces traditional mechanical verification methods (such as physical presence checks or manual confirmation) with electronic location information acquisition and blockchain-based verification. By using GPS coordinates and blockchain smart contracts to automatically verify and record visitation, the system achieves higher precision in determining actual visitation while maintaining system adaptability for various event types.
2Ease of operation
If location information is used to grant tokens without verification, then the ease of operation is improved, but the reliability of token issuance deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the information coordination device continuously monitors and verifies location information against the predetermined range before triggering token issuance. The system provides feedback loops that confirm whether the user's location meets the criteria for token granting, ensuring reliable verification while maintaining automated operation. This feedback mechanism prevents erroneous token issuance while keeping the process straightforward for users.
Solution Approach 2:
The patent establishes predetermined ranges and verification criteria before the token issuance process begins. By pre-configuring the geographic boundaries and validation rules, the system ensures that location verification is performed reliably without requiring complex real-time decision-making. This preliminary setup maintains ease of operation during actual issuance while guaranteeing reliability through pre-established validation parameters.
3Manufacturing precision
If a predetermined range is set for location verification, then the manufacturing precision of the verification system is improved, but the device complexity increases
Solution Approach 1:
The patent uses parameter changes by defining the predetermined range through adjustable geographic coordinates and radius values. Instead of complex geometric calculations, the system verifies location by comparing the user's coordinates against pre-set parameters (center point and radius). This approach achieves high verification precision while keeping the device relatively simple, as it relies on basic coordinate comparison rather than complex spatial algorithms.

AI summary
A system for granting tokens related to a place or area to users who are actually visiting or have visited the place or area is provided. The system includes: an acquisition unit that acquires, via an information coordination device that acquires first location information indicating the location of a user terminal of a user who wishes to obtain an NFT, the first location information; a determination unit that determines that the NFT can be granted to the user if the location of the user terminal indicated by the first location information is within a predetermined range; and an NFT granting unit that grants the NFT to the user's wallet address on a blockchain when the determination unit determines that the NFT can be granted.
