Credit Card Substrate Segmentation for Fraud Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increased use of credit cards with RFID capabilities has led to potential fraud issues, as stolen cards can be used without verification, highlighting a need for enhanced security measures, as traditional signature requirements are often overlooked by merchants.
Innovation Solution
A credit card system with a deformable or removable portion on the substrate, which, when altered by the owner, requires secondary identification for use, such as a picture ID, PIN, or biological identification, to ensure the card can only be used by the actual owner, and is readable by card readers to communicate this requirement to financial institutions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If RFID capability is added to credit cards for quick verification, then convenience and speed of use are improved, but security against fraud deteriorates because stolen cards can be used without verification
Solution Approach 1:
The credit card is divided into two functional parts: a permanent substrate containing account information and a removable portion that can be detached by the user. This segmentation allows the card to maintain RFID convenience while adding a physical security layer that prevents unauthorized use of stolen cards, as the removable portion acts as a unique identifier that must be present for full card functionality.
2Productivity
If signature requirements are relaxed for micro-purchases, then ease of transaction is improved, but security deteriorates because stolen cards can be used without verification
Solution Approach 1:
The user performs a preliminary action by removing a portion of the card substrate during card issuance or setup. This pre-configured physical modification creates a unique security feature on each card that merchants can verify, allowing quick transactions while maintaining security through a physical verification step that is simpler and more reliable than signature requirements.
3Reliability
If 'See ID' or 'CID' is added to the signature line, then security requirement is improved, but ease of use deteriorates because merchants must verify identification
Solution Approach 1:
The security verification is shifted to the cardholder rather than the merchant. The user removes a portion of the card substrate themselves, creating a permanent physical modification that serves as their own identification verification. This eliminates the burden on merchants to check IDs while maintaining security, as the physical modification is self-evident and requires no additional verification steps.

AI summary
The invention is a credit card system which utilizes a substrate having a machine readable user account number and, a user removable portion of the substrate. The credit card identifies if the user removable portion of the substrate has been disturbed, the reader requests a secondary user identification to verify that the user is authorized to use the credit card.
