Split Transaction Card with Segmented Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional transaction cards are vulnerable to theft and lack secure authentication, as they can be easily stolen and used by unauthorized individuals, and do not require multiple users to authorize transactions.
Innovation Solution
A transaction card is divided into multiple separable portions, each containing a magnetic stripe and chip, which can be removably coupled to form different configurations, ensuring the card is only readable and usable when all authorized users contribute their respective portions, implementing a multifactor authentication system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a transaction card is made as a single piece containing all personal information, then the card is easy to use and operate, but the card is vulnerable to theft and can be used by unauthorized individuals
Solution Approach 1:
The transaction card is divided into multiple separable portions (first card portion and second card portion), each containing a fragment of the magnetic stripe and chip. The portions can be physically separated and must be brought together during a transaction, preventing unauthorized use if one portion is lost or stolen while maintaining ease of use when portions are combined.
2Adaptability or versatility
If a transaction card contains complete personal information and authentication capabilities, then the card can be used independently by a single user, but unauthorized users can also use the card without additional security
Solution Approach 1:
The authentication capability is segmented across multiple card portions, with each portion containing a partial magnetic stripe and chip. The portions work together to form a complete authentication system, enabling multi-user control while maintaining the ability to function independently when all authorized users are present.
Solution Approach 2:
Multiple card portions are designed to be brought together during a transaction, merging their individual magnetic stripe and chip components to form a complete, functional authentication system. This combining mechanism ensures that all authorized users must be present while allowing independent operation when combined.
3Reliability
If a transaction card is divided into multiple separable portions, then the security against theft is improved, but the card structure becomes more complex
Solution Approach 1:
The card is divided into portions that can be separately manufactured and then assembled, with each portion containing essential but incomplete authentication components. This segmentation enhances security while the standardized design of each portion keeps individual component complexity manageable.
Solution Approach 2:
Each card portion is designed with universal features including a magnetic stripe, chip, and connection mechanism that can work together in different configurations. This multi-functionality allows the same basic components to serve multiple purposes, reducing overall system complexity despite the divided structure.

AI summary
A separable or split transaction card may be a transaction card that is separable into multiple parts. The transaction card may be separable into multiple portions through an axis that extends through one or more pieces of personal identification information. The transaction card may transition between two or more configurations. A first configuration may be one in which the multiple card portions are not connected, all of the separated pieces of personal identification information are disabled, and the transaction card is disabled. A second configuration may be one in which the multiple card portions are connected, one or more of the separated pieces of personal identification information are enabled, and the transaction card is enabled and may be read when inserted into a card reading machine.
