Mobile Terminal Card Module with Fingerprint Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals face security vulnerabilities and inconvenience in using stored card information for payments, as existing solutions lack robust authentication and are prone to misuse due to the lack of a secure, user-specific payment mechanism.
Innovation Solution
A mobile terminal with a physically withdrawable card module that requires user authentication, such as fingerprint sensing, to enable secure payment functions, allowing only authorized users to access and use the card information, thereby enhancing security and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If card information is stored in a mobile terminal for payment convenience, then payment efficiency is improved, but security is worsened due to potential loss or unauthorized access
Solution Approach 1:
The card module is divided into a terminal body portion and a cover portion that can be separated. The terminal body contains the payment function and card information, while the cover provides physical protection and can be detached to limit payment functionality, creating segmented security zones.
Solution Approach 2:
A fingerprint sensor is introduced as an intermediary authentication mechanism between the user and the card information. The sensor requires biometric verification before allowing access to payment functions, adding a security layer without compromising payment efficiency.
2Reliability
If a physically withdrawable card module is implemented, then security is improved through user authentication, but device complexity is worsened
Solution Approach 1:
The card module merges multiple functions into a single integrated component: card information storage, fingerprint authentication, and payment processing are combined in one module that can be inserted into or removed from the terminal body, reducing the need for separate components.
Solution Approach 2:
The card module is designed as a universal interface that can work with different terminal bodies and cover configurations. The same card module can be used across various device types, and the module itself performs multiple functions including authentication, storage, and payment execution.
3Ease of operation
If the card module is always accessible, then ease of operation is improved, but security is worsened due to unauthorized use
Solution Approach 1:
The card module transitions between different states: inserted/removed, authenticated/unauthenticated, and active/inactive. These dynamic state changes allow the system to adapt security levels based on operational context, providing ease of use when authenticated while preventing unauthorized access.
Solution Approach 2:
The system performs preliminary authentication through fingerprint verification before enabling payment functions. This preemptive security measure prevents unauthorized access attempts before they can compromise the system, while still allowing quick authenticated access.
4Adaptability or versatility
If multiple cards are stored for different payments, then adaptability is improved, but loss of information is worsened if the terminal is lost
Solution Approach 1:
Card information is extracted from the main terminal storage and placed in a separate, physically removable card module. This extraction allows users to securely store multiple card types while limiting exposure, as the module can be removed and stored separately from the main terminal when not in use.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a secure and convenient payment experience by ensuring only authorized users can access the card module, reducing the risk of unauthorized transactions and simplifying the payment process by eliminating the need for multiple card steps.
