Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face security risks and inconvenience when carrying multiple bank cards for transactions, as losing a card can result in asset loss and inter-bank transactions may incur unnecessary costs.
Innovation Solution
A data interaction method and system involving a simulation card, smart cover, and real card manager for secure data transmission, allowing users to select and manage real cards without physically carrying them, using secure connections and encryption for secure data interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users carry multiple bank cards for transactions, then transaction convenience is improved, but security risk increases and asset loss may occur
Solution Approach 1:
The patent uses a simulation card that contains copied information from real bank cards. The simulation card stores card information, verification codes, and other data that replicate the functionality of real cards without requiring users to carry the actual physical cards, thereby maintaining transaction convenience while reducing security risks associated with carrying multiple real cards
Solution Approach 2:
The patent introduces a card management system as an intermediary between users and real bank cards. This system manages multiple real cards and allows users to access them through a unified interface via the simulation card, eliminating the need to carry multiple physical cards while maintaining secure access to all necessary accounts
2Ease of operation
If users carry only some bank cards for convenience, then carrying burden is reduced, but inter-bank transaction costs increase
Solution Approach 1:
The simulation card is designed to be universal and can simulate multiple different bank cards from various banks. Users can store and access information from cards of different banks through a single simulation card, enabling them to perform transactions at any bank without carrying multiple physical cards, thus avoiding inter-bank transaction fees while maintaining carrying convenience
3Ease of operation
If a unified card system is implemented, then carrying convenience is improved, but system complexity increases
Solution Approach 1:
The patent divides the card management system into distinct functional modules: a card management server that handles real card information, a simulation card that stores and transmits data, and a transaction terminal that processes operations. This segmentation allows the complex functionality to be distributed across multiple components, making the system manageable while providing unified access through a single simulation card

AI summary
A data secure interaction method and system, wherein the method comprises: a card sleeve acquiring a card sleeve-end real card information list, and the card sleeve giving a prompt about the card sleeve-end real card information list; the card sleeve receiving a real card choosing instruction and determining a chosen real card; and a simulation card receiving first data sent by a transaction terminal and sending the first data to the card sleeve; the card sleeve giving a prompt about the first data, receiving a confirmation instruction for confirming that the first data is correct, and sending the first data to a real card manager; the real card manager receiving the first data sent by the card sleeve and sending the first data to the chosen real card. Through this data interaction method, data interaction among the simulation card, the card sleeve and the real card manager can be realized, in order to provide a data interaction solution that is not only convenient for a user to carry, but also higher in security.
