Magnetic Shielding Card Holder for Smartcard Skimming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern smart cards with electronic devices are vulnerable to skimming and data theft due to their susceptibility to wireless transmissions, and existing methods to prevent this often compromise their versatility and accessibility.
Innovation Solution
A shielding card holder system that includes a card protector with magnetic engagement mechanisms to securely attach a card holder to the card protector, allowing for adjustable positioning and secure attachment to clothing, thereby shielding wireless transmissions and preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If foil or similar sleeves are used to shield wireless transmissions, then security against skimming is improved, but ease of operation deteriorates because the sleeve must be retrieved from a wallet or purse and the card fully removed from the sleeve
Solution Approach 1:
The system divides the shielding function into a separate card protector component that can remain attached to the card while allowing the card to be accessed. The card holder and card protector are separable, enabling the card to be removed for use while the protector remains as a reusable shielding component.
Solution Approach 2:
The card nests within the card holder, which in turn attaches to the card protector. This nested structure allows the card to be securely held within the holder while the entire assembly attaches to the protective shielding layer, providing both security and easy access.
2Reliability
If foil or similar sleeves are used to shield wireless transmissions, then security against skimming is improved, but adaptability deteriorates with respect to options for how to wear or otherwise attach the card to one's self
Solution Approach 1:
The card protector is designed as a universal base component that can accommodate different card holders and attaching mechanisms. The magnetic attachment system and various holder configurations enable multiple wearing options including on wallets, belts, or clothing, making the shielding system adaptable to different user preferences and situations.
Solution Approach 2:
The system incorporates movable and adjustable components, including the card holder that can be positioned at different locations on the card protector, and attaching mechanisms that can be configured for different wearing positions, providing dynamic adaptability rather than fixed positioning.
3Ease of operation
If a card holder with magnetic engagement is used to attach to the card protector, then ease of operation is improved, but device complexity increases due to the magnetic engagement mechanisms
Solution Approach 1:
The system replaces complex mechanical fastening mechanisms with simple magnetic engagement. The magnets provide automatic attachment when components are brought close together and easy detachment by pulling apart, eliminating the need for buttons, clips, or other mechanical fasteners while maintaining secure holding.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively shields smart cards from skimming and data theft while maintaining versatility in accessibility and attachment options, providing a secure and convenient method for carrying and using smart cards.
Implementation Method 1
A protector magnet on the card protector is adapted to magnetically engage with a holder magnet on the card holder or the card holder itself to removably attach the card holder to the card protector
Implementation Method 2
A securing member may be utilized to secure the card protector against an article of clothing, with the securing member including a securing magnet adapted to magnetically engage with the protector magnet through the clothing
Implementation Method 3
a card protector adapted to shield wireless transmissions from a card such as a smartcard
