Solution Overview
Problem
Existing electronic devices lack a convenient and efficient method for processing cost payments, particularly in environments where multiple payment methods like NFC, MST, and barcode are needed, often requiring complex user interactions and multiple device operations.
Innovation Solution
An electronic device equipped with a security memory for storing payment information and a control module that manages NFC and MST operations, allowing for simultaneous signal processing and output as a single screen interface, along with fingerprint detection for secure authentication, enabling easy and convenient payment processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple payment methods (NFC, MST, barcode) are supported separately, then payment versatility is improved, but device complexity and user interaction complexity increase
Solution Approach 1:
The patent combines multiple payment methods (NFC, MST, barcode) into a single integrated payment application interface. The control module统一管理 all payment methods, presenting them through one unified screen rather than requiring separate applications or complex switching between multiple interfaces. This merging approach maintains versatility while reducing operational complexity.
Solution Approach 2:
The payment application is designed as a universal interface that handles multiple payment methods through a single entry point. The control module provides multi-functional capabilities, allowing users to access NFC, MST, and barcode payment options within one application, eliminating the need for separate dedicated applications for each payment method.
2Reliability
If fingerprint authentication is implemented, then payment security is improved, but operation time and user interaction steps increase
Solution Approach 1:
The system performs fingerprint authentication automatically as a preliminary step before processing the payment transaction. By pre-authenticating the user through fingerprint detection, the system ensures security is verified before the actual payment operation, making the authentication process seamless and minimizing perceived user effort.
Solution Approach 2:
The fingerprint authentication is implemented as an automatic self-service mechanism. The sensor unit automatically detects and verifies the user's fingerprint without requiring manual intervention beyond placing the finger on the sensor. This self-service approach streamlines the authentication process, reducing both time and user interaction complexity.
3Measurement precision
If separate screen interfaces are used for NFC and MST operations, then signal processing accuracy is maintained, but ease of operation deteriorates
Solution Approach 1:
The control module merges the display of signal processing information for both NFC and MST operations into a single unified screen interface. Instead of requiring separate screens or applications for each payment method, the system presents all relevant signal processing information in one integrated view, maintaining accuracy while improving ease of operation.
