Offline QR Code Resource Transfer via Local Graphic Code Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for public facility usage, such as metros and buses, require network connectivity to transfer resources via QR codes, limiting offline usage and complicating unified management across different facilities.
Innovation Solution
A resource transfer method and apparatus that involves a terminal with a specified application client storing a graphic code including a user identifier, allowing offline QR code scanning for resource transfer, and interacting with multiple third-party servers for unified management through a specified server and third-party server interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network connectivity is required for resource transfer via QR codes, then resource transfer can be performed through centralized server management, but offline usage is limited and system complexity increases
Solution Approach 1:
The terminal performs preliminary actions by storing graphic codes locally before offline usage is needed. The graphic code includes user identifier information that can be presented without network connectivity, allowing the terminal to operate independently when offline while maintaining reliability through pre-configured authentication data
Solution Approach 2:
The terminal is designed with multi-functionality to operate in both online and offline modes. It can present stored graphic codes when offline and switch to network-based resource transfer when online, making the system universally applicable across different connectivity conditions without requiring separate systems
2Adaptability or versatility
If multiple public facilities are managed separately, then each facility can be independently controlled, but unified management across facilities becomes complex
Solution Approach 1:
A unified management system is implemented that can manage multiple types of public facilities through a common interface. The system recognizes graphic codes across different facilities (metros, buses, shared bicycles) and performs resource transfer operations through standardized processes, enabling facilities to be independently controlled while maintaining centralized management
Solution Approach 2:
The terminal acts as an intermediary between users and multiple public facilities. It stores graphic codes and presents them to various facilities, while the management system serves as an intermediary between different facilities and the central control, standardizing interactions and reducing overall system complexity
3Reliability
If QR code scanning requires network connectivity, then centralized verification can be performed, but user access speed and convenience are reduced
Solution Approach 1:
The terminal performs preliminary action by storing verified graphic codes locally before they are needed for access. This allows the terminal to present pre-verified codes immediately without waiting for network-based verification, reducing access time while maintaining verification accuracy through the use of pre-authenticated codes
Solution Approach 2:
The system creates copies of verified authentication data (graphic codes) and stores them locally on the terminal. These copies can be presented without network connectivity, allowing fast access while the original verification accuracy is maintained through the use of replicated authenticated information
