Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional credit cards are vulnerable to data theft and transaction processes are cumbersome, lacking in security and convenience.
Innovation Solution
A portable device with a flexible semi-transparent OLED display, embedded camera, and fingerprint sensor that securely displays credentials and processes transactions by recognizing items through pattern recognition, allowing users to authenticate and confirm purchases biometrically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional credit cards are used to display sensitive data, then transaction information is easily accessible, but data security is compromised due to over-the-shoulder stealing
Solution Approach 1:
The system performs preliminary authentication via fingerprint sensor before displaying any sensitive credential information. The authentication data is verified in advance, and only after successful authentication does the system proceed to display the credential and transaction information, preventing unauthorized access
2Productivity
If conventional payment processing methods are used, then transactions can be completed, but the process is slow and cumbersome requiring multiple steps
Solution Approach 1:
The patent combines multiple functions into a single portable device: fingerprint authentication, credential display, item recognition via camera, and transaction processing. This integration eliminates the need for separate devices and multiple manual steps, streamlining the entire payment process into one unified workflow
Solution Approach 2:
The portable device serves multiple functions: it acts as an authentication device with fingerprint sensor, a display device for credentials, a camera for item recognition, and a transaction processor. This multi-functionality allows a single device to handle the entire payment workflow, reducing complexity and improving efficiency
3Loss of information
If a portable device displays credential information, then users can view transaction details, but security is reduced if the device is lost or stolen
Solution Approach 1:
The system requires preliminary fingerprint authentication before any credential information becomes visible on the display. The authentication check is performed in advance, ensuring that only authorized users can view sensitive data, thereby maintaining security while enabling information visibility
