Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for activating Near Field Communication (NFC) cards are inefficient and provide a poor user experience, particularly in environments with poor mobile signal coverage, such as subway gates, where the process of matching and activating emulated cards is slow and prone to failure.
Innovation Solution
A method and apparatus that automatically detect changes in geographic location and activate the corresponding NFC card based on preset location change rules, eliminating the need for manual activation and reducing reliance on timely GPS signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual operation or terminal automatic determination is used to activate NFC cards, then the activation process can be completed, but the user experience is poor and the process is slow in environments with poor mobile signal coverage
Solution Approach 1:
The system pre-configures multiple emulated NFC cards in the terminal before the user needs them. When the user approaches a usage scenario (detected via GPS location matching), the corresponding NFC card is already prepared and can be activated immediately without manual intervention or slow terminal determination processes.
Solution Approach 2:
The patent replaces the manual mechanical operation of selecting and activating NFC cards with an automated system that uses GPS location detection and pre-configured card data. This substitution eliminates the delays and failures associated with manual operations and terminal-based automatic determination, especially in poor signal environments.
2Adaptability or versatility
If multiple emulated cards are configured on the terminal, then different application scenarios can be supported, but the complexity of card selection and activation increases
Solution Approach 1:
The system automatically determines which NFC card to activate based on the user's GPS location and pre-configured scenario data. The terminal itself performs the card selection and activation without requiring user intervention, making the system self-serving and eliminating the complexity of manual card selection while supporting multiple scenarios.
Solution Approach 2:
The system continuously monitors the user's GPS location and compares it with pre-configured location data for different NFC card scenarios. When a match is detected, the system automatically activates the corresponding card. This feedback mechanism ensures the correct card is activated for the current scenario without user input.
3Extent of automation
If GPS signal is relied upon for location-based NFC card activation, then automatic activation can be achieved, but the process fails or slows down in environments with poor signal coverage such as subway gates
Solution Approach 1:
The system pre-configures detailed location data including coordinates, geographic ranges, and motion trajectories for each NFC card scenario before use. This preliminary preparation allows the system to determine card activation based on stored reference data rather than relying solely on real-time GPS signal strength, improving reliability in poor signal environments.
Solution Approach 2:
The patent prepares multiple possible location matching methods in advance (coordinate matching, geographic range matching, motion trajectory matching) to cushion against GPS signal failures. If the primary GPS signal is weak or unavailable, the system can fall back on the pre-configured location data and alternative matching methods to ensure successful card activation.

AI summary
A method and apparatus for activating a Near Field Communication (NFC) card involving short range communication can the problems of low efficiency and poor user experience in the process of switching and managing the emulated card. The method includes: detecting (101, 202) a geographical location of a user; and in response to detecting that a change of the geographic location conforms to a preset location change rule, determining and activating (102, 203) an NFC card associated with the preset location change rule, wherein the preset location change rule is configured to characterize entering and/or leaving a preset geographic range.
