Light-Guided Data Carrier Inlay for Anti-Forgery Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data carriers for secure articles such as bank cards and identity cards are susceptible to forgery and require improved protection while maintaining a simple design.
Innovation Solution
A data carrier with a carrier body containing a light guiding element that directs light emitted from a light emitting element, enhancing security through glowing edges and selectively illuminated security elements, using materials like polycarbonate and polyvinyl chloride, and incorporating electronic modules and antennas for power and communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a data carrier includes additional security features such as light emitting elements and light guiding elements, then protection against forgery is improved, but device complexity increases
Solution Approach 1:
The patent combines the light emitting element and light guiding element into an integrated inlay structure that is embedded within the carrier body as a single functional unit. This merging approach allows multiple security features to be combined without proportionally increasing overall device complexity, as the elements work together as a cohesive security mechanism rather than separate additions.
Solution Approach 2:
The light emitting element is embedded within the light guiding element, which itself is integrated into the carrier body layers. This nested arrangement allows the security features to be incorporated within the existing structural framework of the data carrier, minimizing additional complexity while maximizing security functionality.
2Reliability
If a data carrier uses complex multi-layer structures with embedded elements, then security against forgery is improved, but ease of manufacture deteriorates
Solution Approach 1:
The inlay containing the light emitting element and light guiding element is prepared as a pre-assembled unit before being embedded into the carrier body. This preliminary preparation allows the complex security features to be manufactured and tested separately, then integrated into the final product through a standardized embedding process, simplifying overall manufacturing.
Solution Approach 2:
The inlay structure serves multiple functions simultaneously: it provides security against forgery, enables dynamic visual verification through light emission, and can be integrated into standard carrier body manufacturing processes. This multi-functionality reduces the need for separate specialized manufacturing steps for each security feature.
