Solution Overview
Problem
Point of sale (POS) terminals often support multiple contactless payment methods like NFC and MST, but these methods cannot be processed simultaneously, leading to difficulties in determining the appropriate payment method for transactions without user intervention.
Innovation Solution
A method and apparatus for intelligent communication selection that determines the communication capability of a device and selects an optimal communication protocol for data transfer, allowing for real-time switching between NFC and MST payment methods to ensure successful transactions without user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple contactless payment methods (NFC and MST) are supported in a device, then the adaptability and versatility of the payment device is improved, but the device complexity increases and the methods cannot be processed simultaneously
Solution Approach 1:
The patent implements dynamic switching between NFC and MST payment methods based on real-time detection of POS terminal capabilities. The system continuously monitors which payment method is currently being used and automatically transitions to the appropriate protocol when the terminal type changes, resolving the contradiction by making the payment system adaptive rather than static.
Solution Approach 2:
The patent employs feedback mechanisms where the device detects the POS terminal type (NFC or MST) and uses this information to determine the appropriate payment method. The system receives feedback about the current terminal capability and adjusts its communication protocol accordingly, enabling seamless switching without user intervention and managing the complexity of supporting multiple payment methods.
2Ease of operation
If real-time switching between NFC and MST payment methods is implemented, then the ease of operation is improved, but the loss of time for detecting and switching protocols increases
Solution Approach 1:
The patent performs preliminary detection of POS terminal capabilities before initiating the payment transaction. By detecting whether the terminal supports NFC or MST in advance and preparing the appropriate payment protocol beforehand, the system minimizes switching delays during the actual payment process, thus reducing the perceived time loss while maintaining ease of operation.
Solution Approach 2:
The patent ensures continuous payment capability by maintaining both NFC and MST protocols ready for immediate execution. The system continuously monitors terminal type and ensures one of the payment methods is always active and ready, eliminating interruptions and minimizing the time lost during protocol transitions, thereby preserving the continuity of the payment action.
