Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional contactless card environments are used without audio signal receiving devices, then device complexity is reduced, but transaction security and data transmission reliability deteriorate
Solution Approach 1:
The patent applies multi-functionality by enabling audio signal receiving devices (earphones, headphones, VR/AR devices) to serve dual purposes: their primary function and contactless card transaction processing. The audio device's processor and transceiver coil handle both audio processing and NFC communications, eliminating the need for dedicated card readers while improving transaction security through authenticated communication channels.
2Ease of operation
If manual positioning of contactless cards is required for optimal signal strength, then device complexity is reduced, but ease of operation deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where the audio device continuously monitors signal strength from the contactless card and provides real-time guidance to the user through audio prompts. The system detects signal strength variations and instructs users to reposition the card or adjust the device orientation, automatically optimizing the communication link without requiring manual intervention to achieve perfect positioning.
Solution Approach 2:
The system performs self-service by automatically detecting contactless cards, establishing communication links, monitoring signal strength, and guiding users through audio feedback without requiring complex user actions. The audio device autonomously manages the transaction process, from card detection to data extraction, minimizing manual操作步骤 while maintaining operational simplicity.

AI summary
A method, a system, and a computer program product for providing a secure interface for execution of transactions. An audio signal receiving device detects and establishes a near-field communication (NFC) exchange communication link with a first device. The receiving device receives one or more signals from the first device. Each signal is responsive to one or more transmissions sent to the first device by a transceiver coil of the receiving device. Based on a determined signal strength of signals, the receiving device determines a first position of the first device in relation to the receiving device and generates one or more prompts to reposition the first device in relation to the receiving device from the first position to one or more second positions. At least one second position corresponds to a maximum signal strength of signals. The receiving device then extracts information from the first device.
