Solution Overview
Problem
Small-scale local businesses face challenges in promoting the use of digital local currency due to limited investment capacity for digital settlement equipment, and there is a need to induce active communication between customers and store staff for effective digital currency transactions.
Innovation Solution
A mobile application and store tablet-based system that facilitates face-to-face digital local currency transactions using touch screens, where simultaneous touch operations by users and store staff confirm transactions, leveraging blockchain technology for secure settlement processing without extensive equipment investment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If small-scale local businesses adopt digital local currency settlement equipment, then settlement capability is improved, but investment cost increases
Solution Approach 1:
The patent uses smartphone applications as portable copies of settlement terminals. Instead of requiring physical settlement equipment at each store, the system uses mobile devices running specialized apps that replicate the necessary settlement functionality, thereby eliminating the need for expensive fixed equipment installations.
Solution Approach 2:
The patent makes smartphones universal settlement terminals capable of performing various functions including displaying menus, processing payments, and communicating with customers. The same mobile device serves multiple purposes, eliminating the need for separate dedicated settlement hardware at each location.
2Reliability
If digital local currency settlement system is implemented, then transaction security is improved, but system complexity increases
Solution Approach 1:
The patent introduces a server as an intermediary between customer smartphones and store settlement terminals. The server manages authentication, transaction processing, and communication protocols, thereby centralizing complexity in a dedicated system while keeping individual terminal operations simple and secure.
Solution Approach 2:
The patent replaces complex physical cash handling and manual accounting systems with digital electronic transactions. Monetary exchange is substituted by digital currency transfer through mobile applications and servers, automatically recording transactions and eliminating the need for physical cash management infrastructure.
3Ease of operation
If face-to-face settlement is promoted, then customer engagement is improved, but operation time increases
Solution Approach 1:
The patent implements continuous display of settlement progress information to both customers and staff during the transaction process. Visual feedback such as progress bars, animated counters, and real-time status updates keep all parties engaged and informed throughout the entire settlement process, making time investment worthwhile.
Solution Approach 2:
The patent uses color-coded visual indicators and animated displays to communicate settlement status dynamically. Different colors indicate various stages of transaction progress, success, or failure, providing immediate visual feedback that enhances customer understanding and engagement during the settlement process.

AI summary
An application executed at a user terminal with a touch screen displays, on the touch screen, a UI in which a user-side UI for accepting a touch operation by a user and a store-side UI for accepting a touch operation by a staff member of a store are placed, as a settlement UI for settlement of a currency amount of a digital local currency. The application judges whether time during which the touch operation on the user-side UI and the touch operation on the store-side UI are simultaneously continued has reached a specified period of time or not. If the judgment result is true, the application displays a settlement completion notice on the touch screen.
