E-paper ID Card Dynamic Display for Identity Security and Reuse
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current visitor identification cards are often one-time use, leading to resource waste, and those without displayed personal information are susceptible to user identity theft.
Innovation Solution
An e-paper identification card system that includes an e-paper identification card and a data updating apparatus, which captures user images and updates the card to display user data, preventing identity theft by real-time identification and allowing card reuse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If one-time use visitor identification cards are used, then resource waste is avoided, but user identity theft risk increases due to lack of displayed personal information
Solution Approach 1:
The identification card uses an e-paper display that can dynamically change displayed information. The card transitions from displaying no personal information to displaying user identity information when needed, and can be reset for reuse. This dynamic capability resolves the contradiction by providing identity security when required while enabling resource reuse afterward.
Solution Approach 2:
The e-paper display changes its display state from blank to showing personal information, and can be reset back to blank. This parameter change allows the card to provide identity verification when needed while returning to a reusable state, thus preventing identity theft risk without permanent resource consumption.
2Reliability
If visitor identification cards display personal information, then user identity theft is prevented, but resource waste increases due to one-time use limitation
Solution Approach 1:
The e-paper display dynamically switches between displaying personal information and being blank/reset. This allows the card to provide identity security during use and then be reset for reuse, eliminating the need for continuous production of new cards while maintaining security during the identification period.
Solution Approach 2:
Instead of discarding the identification card after one-time use, the e-paper display can be reset to its initial state, recovering the card for reuse. This recovering process prevents resource waste while the card continues to provide identity security through multiple uses.
3Loss of substance
If e-paper display is used for reusable identification card, then resource waste is reduced through card reuse, but device complexity increases due to additional components
Solution Approach 1:
The e-paper display serves multiple functions: it displays personal information for identification, can be reset to blank state, and enables card reuse. This multi-functionality justifies the added complexity by providing both security and reusability from a single component.
Solution Approach 2:
The e-paper display creates a visual copy of personal information that can be displayed and then cleared, allowing the same physical card to serve multiple identification purposes without needing multiple physical cards, thus reducing overall resource consumption despite the added component.
