Removable Transaction Card Chip Structure for Easy Deactivation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for destroying transaction cards, such as cutting them into pieces, are laborious and ineffective for cards with metal components, and there is a need for a more efficient way to inactivate the chip without damaging the card body.
Innovation Solution
A transaction card design incorporating a chip removal element that can be manually detached from the card body, severing electrical connections to render the chip inoperable, allowing the chip to be removed without destroying the card.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the card is cut into small pieces for destruction, then the information security is improved, but the labor required and difficulty of operation increase
Solution Approach 1:
The card structure is segmented into separable components: the card body and the removable chip. This allows the chip containing sensitive information to be independently removed and destroyed without requiring destruction of the entire card, thereby improving information security while reducing operational complexity.
Solution Approach 2:
The chip is extracted as a separate removable component from the card body through the chip removal element. This extraction enables selective removal and destruction of the information-containing chip without damaging the card body, resolving the contradiction between secure information destruction and ease of operation.
2Reliability
If typical destruction methods are used on metal cards, then the information security is maintained, but the ease of operation deteriorates due to inability to easily destroy metal cards
Solution Approach 1:
The card is segmented into the metal card body and the removable chip component. This segmentation allows the chip to be removed and destroyed independently using standard methods, while the durable metal card body remains intact, solving the problem of destroying information on metal cards without compromising operational ease.
Solution Approach 2:
The chip is extracted from the metal card body through the chip removal element, enabling separate handling of the information-containing component. This allows standard destruction methods to be applied to the chip while preserving the metal card body, thereby maintaining information security while improving ease of operation.
3Stability of the object's composition
If the chip is permanently attached to the card body, then the structural integrity is improved, but the ability to inactivate the card by removing the chip is lost
Solution Approach 1:
The chip attachment is designed with dynamic characteristics through the chip removal element, allowing the chip to be firmly attached during normal use for structural integrity, yet easily removable when needed for card inactivation. This dynamic attachment mechanism resolves the contradiction between stability and adaptability.
Solution Approach 2:
The chip removal element acts as an intermediary component between the chip and card body. This intermediary provides a controlled attachment mechanism that maintains structural integrity during use while enabling easy chip removal for card inactivation, thereby resolving the contradiction between stability and versatility.

AI summary
Provided are approaches for removing a chip of a transaction card using a chip removal element. In some approaches, the transaction card may include a body including a first main side opposite a second main side, a chip coupled to the first main side of the body, and a chip removal element disposed between the chip and the body. A first end of the chip removal element may be positioned within a tab recess along the first main side of the body, wherein the chip removal element is operable to decouple the chip from the body when the chip removal element is moved away from the body.
