One Card System Secure Element Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to securely combine multiple cards, such as credit and bank cards, into a single card that can be accepted by merchants and endorsed by issuing banks, while also being compatible with existing card readers and infrastructure, and lack efficient processes for adding or canceling cards.
Innovation Solution
A novel system comprising a device and process that securely combines multiple cards into one card, using a device that can be integrated with portable electronics, with features like magnetic stripe writing and smart card technology, and a business process for secure account information management, authentication, and activation, ensuring compatibility with current card readers and infrastructure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple cards are combined into one card using existing systems, then card consolidation is achieved, but security and authentication reliability deteriorate
Solution Approach 1:
The patent introduces a secure element as an intermediary component that acts as a trusted anchor between the cardholder and the card reading device. This secure element contains cryptographic keys and authentication logic that mediate the verification process, ensuring that card consolidation maintains the same security level as traditional single cards. The secure element verifies the authenticity of each consolidated card account before allowing access, preventing security deterioration.
Solution Approach 2:
The patent creates a universal card platform that can host multiple card accounts (credit cards, debit cards, loyalty cards, etc.) within a single physical card. This multi-functional card uses a standardized interface and authentication mechanism that works across different card types and issuing institutions, achieving consolidation while maintaining universal acceptance and security through the common secure element architecture.
2Adaptability or versatility
If a card combines multiple accounts with display and input devices, then card functionality is enhanced, but device size and robustness deteriorate
Solution Approach 1:
The patent extracts the display, input devices, and account selection interface from the physical card itself and relocates them to an external mobile computing device (smartphone, tablet, or laptop). The card is reduced to its essential function of storing account information and providing a secure authentication interface. The external device handles all complex user interactions, eliminating the need for bulky components within the card while maintaining enhanced functionality.
3Ease of operation
If card information is stored externally without secure process, then card accessibility is improved, but authentication authority deteriorates
Solution Approach 1:
The patent implements preliminary secure enrollment and authentication processes during card issuance and account addition. The secure element is pre-provisioned with cryptographic credentials from trusted issuing institutions before the card is activated. When accounts are added to the consolidated card, secure authentication protocols are performed in advance to verify the legitimacy of each account, ensuring that accessibility does not compromise authentication authority.
4Reliability
If new card processing follows standard procedures, then processing reliability is maintained, but processing time increases
Solution Approach 1:
The patent enables cardholders to self-enroll additional card accounts into their consolidated card through automated electronic processes. Instead of requiring manual verification and physical card issuance for each account, the system allows cardholders to digitally add accounts using secure authentication methods (such as mobile device verification or biometric authentication). This self-service capability maintains reliability through automated security checks while reducing processing time from days to minutes.
