Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing NFC payment systems are limited by their ability to operate in only one mode, either as a card reader or card emulator, failing to adapt to diverse payment habits and scenarios, leading to compatibility issues and increased deployment complexity and costs.
Innovation Solution
An acquiring apparatus equipped with dual NFC modules, one for card reader mode and one for card emulation mode, allowing it to switch between these modes dynamically based on scenario conditions, enabling compatibility with both physical and virtual payment tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an NFC module is configured to work in only one mode (card reader or card emulation), then the device structure is simple, but the adaptability to different payment scenarios is poor
Solution Approach 1:
The patent applies universality by enabling a single NFC module to perform multiple functions through dynamic mode switching. The NFC module can operate in both card reader mode and card emulation mode, allowing one device to serve multiple payment scenarios. This resolves the contradiction by achieving multi-functionality without requiring separate dedicated devices for each mode, thus improving adaptability while maintaining relatively simple device structure.
Solution Approach 2:
The patent implements dynamics through the controller's ability to dynamically switch the NFC module between different working modes based on scenario conditions. The system can adaptively change its operational state (card reader or card emulation) according to the payment scenario requirements, enabling the device to be versatile without requiring complex permanent configurations for each mode.
2Reliability
If separate devices are deployed for card reader mode and card emulation mode, then each device can be optimized for its specific function, but the deployment complexity and costs increase
Solution Approach 1:
The patent merges the functionality of separate card reader devices and card emulation devices into a single unified NFC module. By combining both modes in one module controlled by a controller, the system achieves function-specific optimization for both modes while eliminating the need for separate device deployments, thus reducing deployment complexity and costs while maintaining reliability.
3Adaptability or versatility
If dual NFC modules are deployed to support both modes simultaneously, then compatibility with various NFC payment methods is improved, but the device complexity increases
Solution Approach 1:
The patent applies universality by designing a single NFC module that can universally support both card reader and card emulation modes through dynamic switching. This approach achieves compatibility with various NFC payment methods while avoiding the need for two separate physical NFC modules, thus improving versatility while keeping device structure relatively simple compared to dual-module implementations.
