Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of general use for contactless cards in personal identification due to the absence of necessary infrastructure and acceptance issues related to authenticity checks of electronic personal identification carriers.
Innovation Solution
A method for producing a security layered construction with a transponder layer and a cover layer, incorporating a wire conductor coil and chip arrangement, which allows for authenticity verification through security printing and chip data correlation, enabling both visual and electronic verification without requiring electronic data access means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If contactless cards are used for personal identification, then convenience and automation are improved, but authenticity verification becomes problematic without electronic data access means
Solution Approach 1:
The identification system is segmented into two independent parts: a visually verifiable security printing layer and an electronic transponder layer. This segmentation allows the security printing to provide immediate visual authenticity verification without requiring electronic access means, while the transponder handles automated data processing.
Solution Approach 2:
The security printing acts as an intermediary between the user and the electronic transponder system. It provides a tangible, visually verifiable element that mediates the authenticity check, allowing users to verify documents without needing electronic readers or complex verification infrastructure.
2Reliability
If security printing is added to the transponder layer, then authenticity check capability is improved, but device complexity increases
Solution Approach 1:
The patent merges the security printing and transponder into a single integrated layered construction where the security printing is applied directly to the transponder substrate. This combining approach adds verification capability while minimizing the increase in complexity by using a unified structure rather than separate components.
Solution Approach 2:
The transponder substrate serves multiple functions: it acts as both the electronic circuit carrier and the base for security printing. This multi-functionality reduces overall system complexity by eliminating the need for separate substrates or additional bonding layers.
3Reliability
If the transponder is sealed with a cover layer, then protection against tampering is improved, but access to chip arrangement becomes restricted
Solution Approach 1:
The chip arrangement is nested within the transponder substrate, which itself is nested within the sealed layered construction. This nested structure provides robust tamper resistance while maintaining organized access hierarchies, where the chip remains accessible to the transponder circuitry despite being enclosed.
Solution Approach 2:
The cover layer is implemented as a thin sealing film that provides tamper resistance and protection while maintaining a compact structure. The thin film nature allows the sealed construction to remain manageable in size while still providing effective sealing and protection against unauthorized access.
