Payment Card Powering via External Electromagnetic Induction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of batteries into payment cards increases manufacturing costs and design complexities, while also requiring proper disposal, and existing battery-less solutions lack the ability to dynamically update displays and magnetic stripes.
Innovation Solution
A payment card that receives power from an external electromagnetic signal, using energy storage elements and a voltage regulator to power a display and dynamic magnetic stripe, allowing for dynamic data changes without the need for an internal battery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a battery is integrated into the payment card to power displays and dynamic magnetic stripes, then enhanced functionality and security features are achieved, but manufacturing costs and design complexities increase
Solution Approach 1:
The patent removes the battery from the payment card system, extracting the power source component entirely. Instead, the card uses passive components (magnetic stripe, display, antenna) that can be powered externally during transactions through electromagnetic induction from the card reader, thereby reducing design complexity while maintaining functionality.
Solution Approach 2:
The card reader system serves multiple functions: it acts as both the transaction processing device and the power source for the card. The electromagnetic field generated for data transfer also provides power to the card's display and magnetic stripe components, eliminating the need for a dedicated battery.
2Adaptability or versatility
If a battery is integrated into the payment card to power security features, then dynamic data display and magnetic stripe updates are enabled, but manufacturing costs increase
Solution Approach 1:
The battery component is extracted from the card assembly, simplifying the manufacturing process. The card becomes a passive element that requires no internal power source, reducing bill of materials costs and assembly complexity while maintaining security functionality through externally powered components.
Solution Approach 2:
The card system provides its own power needs through the transaction process itself. The electromagnetic field required for data communication automatically powers the display and magnetic stripe components when needed, eliminating the need for separate battery manufacturing and installation processes.
3Adaptability or versatility
If a battery is included in the payment card to enable dynamic features, then displays and magnetic stripes can be updated, but proper disposal requirements are created
Solution Approach 1:
The battery is completely removed from the card construction, eliminating the source of environmental harm. The card becomes free of hazardous materials, allowing it to be disposed of as regular paper or plastic waste rather than requiring special battery disposal procedures.
Solution Approach 2:
The card is designed as a disposable or easily replaceable item without embedded batteries or complex electronics. When the card needs replacement, the entire card can be discarded and replaced without special disposal procedures, as it contains no hazardous battery components.
