Embedded Magnetic Stripe in Two-Piece Transaction Card
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional transaction cards have security vulnerabilities due to externally exposed magnetic stripes, which are easily tampered with and can have issues with durability and aesthetics.
Innovation Solution
The magnetic stripe is embedded inside a two-piece card construction between the card inlay and housing, with a pocket formed during injection molding or CNC processing, and a stripe indicator on the exterior to indicate its location, enhancing security and aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the magnetic stripe is exposed on the exterior of the card, then it is easy to access and read information, but the card becomes vulnerable to tampering and information theft
Solution Approach 1:
The magnetic stripe is extracted from the exterior surface and embedded within the card body, specifically in a pocket formed between the card inlay and card housing. This extraction removes the vulnerability of external exposure while maintaining the stripe's functionality for data reading through the card's front surface.
Solution Approach 2:
The magnetic stripe is nested within a pocket structure formed between the card inlay and card housing. The stripe is positioned inside this nested space, protected by the surrounding card materials, yet remains accessible from the front surface for reading operations.
2Ease of manufacture
If the magnetic stripe is affixed to the exterior surface of the card, then the manufacturing process is simple, but the magnetic stripe is susceptible to wear and tear
Solution Approach 1:
The magnetic stripe is nested within a pocket structure formed between the card inlay and card housing. This nested positioning protects the stripe from external wear and tear while the pocket is formed through standard manufacturing processes like injection molding or CNC machining, maintaining manufacturing feasibility.
Solution Approach 2:
The card inlay and card housing act as protective shells that enclose the magnetic stripe. These thin film structures provide physical protection to the stripe against environmental factors and mechanical wear, while allowing the card to maintain its flexibility and form factor.
3Reliability
If the magnetic stripe is embedded inside the card frame, then security and aesthetics are improved, but the device complexity increases
Solution Approach 1:
The card is segmented into distinct components: card inlay, card housing, and magnetic stripe, with each serving a specific function. The pocket structure is formed by the interaction between the inlay and housing segments, creating a protected environment for the stripe without requiring a completely new card architecture.
Solution Approach 2:
The card inlay and card housing serve multiple functions: they provide structural support, aesthetic appearance, and simultaneously create the protective pocket for the magnetic stripe. This multi-functionality reduces the need for additional dedicated security components, balancing protection with design simplicity.
