Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing NFC card configuration methods are inflexible and inefficient, as they do not adapt to diverse user interaction habits across different application scenarios, leading to reduced communication interaction efficiency.
Innovation Solution
A method and device for switching NFC cards, where the electronic device determines and activates a non-smart NFC card based on user requirements or scene identification, allowing for efficient near-field communication interaction by replacing smart NFC cards in the NFC smart tag.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single fixed NFC card configuration is used, then the device structure is simple, but it cannot meet diverse user interaction requirements in different application scenarios
Solution Approach 1:
The NFC card configuration is made dynamic through scene-based automatic switching. The system detects the current application scenario (such as payment, transit, or access control) and automatically activates the appropriate NFC card from multiple pre-configured cards, allowing the system to adapt to different requirements without manual intervention while maintaining simple user interaction.
Solution Approach 2:
The electronic device is designed to support multiple NFC cards with different functions simultaneously. Each NFC card can be configured for specific application scenarios (payment, transit, identification), and the system provides a unified interface for managing all cards, making the device universally applicable across multiple use cases without requiring separate devices for each function.
2Productivity
If manual NFC card switching is required for each application scenario, then card configuration remains simple, but user interaction efficiency decreases
Solution Approach 1:
The system automatically performs NFC card switching based on detected application scenarios without requiring user intervention. The electronic device monitors the current context (through sensors, application state, or NFC tag detection) and autonomously selects and activates the most appropriate NFC card, thereby improving interaction efficiency while keeping operations simple for the user.
Solution Approach 2:
The system implements feedback mechanisms where the detected application scenario informs the NFC card selection process. The system continuously monitors usage context and adjusts the active NFC card accordingly, creating a closed-loop system that optimizes interaction efficiency based on real-time conditions while maintaining ease of operation through automatic adaptation.
3Adaptability or versatility
If multiple NFC cards are pre-configured for different scenarios, then adaptability improves, but device complexity and management difficulty increase
Solution Approach 1:
The system introduces a scene detection module as an intermediary between the user and multiple NFC cards. This intermediary automatically identifies the current application scenario and selects the appropriate NFC card, shielding the user from the complexity of managing multiple cards. The scene detection mechanism translates diverse application requirements into simple automatic card selection, maintaining adaptability while reducing management complexity.

AI summary
The present invention provides a method and device for switching an NFC card. The method can include determining a non-smart NFC card from a card set that includes smart NFC cards that are activated by default. The method can further include performing an activation operation on the non-smart NFC card, and calling the non-smart NFC card on which the activation operation has been completed to perform near-field communication interaction with a card reading device in a case of receiving response information of activation success, where the response information of activation success indicates that the non-smart NFC card and the smart NFC cards do not conflict. Through the technical solution of the present invention, the near-field communication interaction efficiency based on the NFC card can be improved.
