Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If contactless communication means are permanently activated to detect card presence, then card detection capability is improved, but power consumption increases significantly
Solution Approach 1:
The contactless communication means are activated periodically at regular intervals rather than permanently, using short pulses to detect card presence. This periodic activation reduces power consumption while maintaining the ability to detect when a card is brought near the terminal.
Solution Approach 2:
The system uses the card's own response to the activation signal to determine its presence and communication capabilities, eliminating the need for continuous active scanning by the terminal.
2Reliability
If contactless communication means are activated during card approach, then card detection is improved, but transaction time increases due to additional activation and information sending
Solution Approach 1:
The terminal activates contactless communication means in advance during the card approach phase to detect card presence before the card is fully inserted or positioned. This preliminary detection allows the system to prepare for the transaction without adding time during the actual payment processing.
Solution Approach 2:
The system dynamically adjusts the activation timing of contactless communication based on the detected position and movement of the card, optimizing the detection window to minimize additional transaction time while ensuring reliable detection.
3Adaptability or versatility
If multiple communication modes are simultaneously activated, then communication versatility is improved, but security risks increase due to simultaneous contact and contactless processing
Solution Approach 1:
The terminal segments the activation of different communication modes in time, activating contactless, contact, and magnetic modes sequentially rather than simultaneously. This temporal segmentation ensures that only one communication mode processes a transaction at a time, preventing security conflicts while maintaining support for all card types.
Solution Approach 2:
The system dynamically selects and activates the appropriate communication mode based on real-time detection of card presence and type, ensuring that only the relevant interface is active during each transaction phase.
