Contactless chip cards face security risks due to the trade-off between convenience and security, as they can be vulnerable to attacks like relay attacks and unauthorized access without additional authentication measures.
Innovation Solution
A chip card arrangement that incorporates an optical coding element, allowing secure contactless interaction by requiring knowledge of an optically capturable code for authorization and payment processes, eliminating the need for additional security features like PIN input or electromagnetic field protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If contactless chip cards are used for authorization processes, then convenience is improved, but security deteriorates due to vulnerability to relay attacks and unauthorized access
Solution Approach 1:
The patent combines two authentication factors into a single contactless interaction: an optically capturable code (visual element) and an electronic circuit with cryptographic functions. This merging allows the system to maintain convenience while enhancing security, as both elements must work together for successful authorization, preventing relay attacks and unauthorized access that plague traditional contactless cards alone.
2Reliability
If additional security functions like PIN input or fingerprint authentication are added, then security is improved, but device complexity and ease of operation worsen
Solution Approach 1:
The patent uses an optically capturable code as a visual copy or representation of the authentication credential. Instead of requiring physical interaction with additional security devices (fingerprint scanners, PIN pads), the system captures an optical image of the code and uses it for verification. This approach provides enhanced security without adding physical complexity or requiring additional user actions beyond viewing and presenting the code.
3Reliability
If electromagnetic field protection is added to prevent unauthorized access, then security is improved, but ease of operation and device complexity worsen
Solution Approach 1:
The patent replaces electromagnetic field protection mechanisms (which would require additional hardware and complex shielding) with an optical code verification system. The optical code serves as a cryptographic key that must be present for authorization, eliminating the need for complex electromagnetic shielding while maintaining security. This substitution preserves ease of operation as the system remains contactless and requires no additional physical barriers.

Function Achieved in This Case
Enhances security and convenience by ensuring that only authorized interactions can occur, as the optical code can be captured without removing the chip card from a container, providing a high level of protection against unauthorized access.
