Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If static information is used on identification cards, then the card structure is simple and成本低, but the security is vulnerable to hacking and interception
Solution Approach 1:
The patent applies dynamics by transitioning from static card information to dynamic validation codes. The card displays a source validation code (SVC) that changes based on transaction parameters, and the terminal generates a destination validation code (DVC) in real-time. This dynamic code generation resolves the security vulnerability of static information while maintaining relatively simple card structure requirements.
Solution Approach 2:
The patent changes the parameter state from static to dynamic by introducing time-sensitive and transaction-specific validation codes. The SVC and DVC are generated based on multiple parameters including card information, terminal information, and transaction details, creating a unique security parameter set for each transaction that resists hacking and interception.
2Reliability
If additional instruments/hardware for user identification are added, then security is improved, but costs increase and practicality decreases for large-scale use
Solution Approach 1:
The patent applies universality by making the validation code system multi-functional. The same card can be used for different transaction types, and the terminal can serve multiple purposes (displaying SVC, reading card info, generating DVC). This eliminates the need for separate identification instruments while maintaining security, making the system cost-effective for large-scale deployment.
Solution Approach 2:
The patent uses copying by generating validation codes that are digital representations of security verification. Instead of requiring physical biometric scanners or additional hardware tokens, the system creates and verifies digital code copies (SVC and DVC) that serve as security instruments, dramatically reducing hardware requirements and costs.
3Object-affected harmful factors
If dynamic validation codes are implemented, then security against hacking is improved, but the processing time and system complexity increase
Solution Approach 1:
The patent applies preliminary action by pre-generating and displaying the source validation code (SVC) on the card before the transaction is fully processed. The terminal also prepares to generate the destination validation code (DVC) in advance. This preliminary preparation of validation codes streamlines the transaction process, reducing actual processing time while maintaining dynamic security.
Solution Approach 2:
The patent replaces complex mechanical verification systems with streamlined digital code generation and verification. Instead of using time-consuming biometric scanning or multiple hardware verification steps, the system uses rapid digital generation of SVC and DVC codes with simple visual or optical verification, significantly reducing transaction processing time while maintaining strong anti-hacking properties.

AI summary
In general, embodiments of the present invention relate to a card and associated methods for automated information (static and dynamic) exchange pursuant to a commercial transaction. In a typical embodiment, the card (e.g., a credit card, a debit card and/or a smart card) comprises an energy component for providing power to the card and a back display (e.g., positioned on the back or magnetic strip side of the card) for displaying card information being used in the commercial transaction. Upon display, a terminal (e.g., a point of sale terminal) will scan/read the card information and generate a corresponding source validation code (SVC). An imager positioned on the back of the card will scan/read the SVC and card validation code (CVC) logic on the card will generate a CVC based on the SVC (e.g., based on a validation result of the SVC). A biometric reader positioned on a front side of the card will take a biometric reading from a user of the card and corresponding user validation code (UVC) logic will generate a UVC based on the biometric reading. The underlying commercial transaction can then be validated (e.g., by a server associated with the terminal or by validation logic on the card itself), a validation result can be displayed on a front display (e.g., positioned on the front side of the card).
