Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Contactless smartcards and RFID smartcards are vulnerable to unauthorized reading due to their ability to communicate wirelessly, and existing security measures like software encryption are not always effective, especially when the cards are not encrypted.

Innovation Solution

A device comprising a first panel for holding the smartcard and a second panel with shielding material that blocks electromagnetic signals, coupled by a hinge which keeps the panels together to prevent reading and can be separated with a force to allow authorized access, using materials like aluminum or radio frequency blocking paper to prevent magnetic, radio frequency, microwave, or optical signals from being read.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If contactless smartcards communicate wirelessly with readers, then convenience and accessibility are improved, but vulnerability to unauthorized reading increases

Engineering Contradiction:

Improvewireless communication convenienceVSAvoidunauthorized reading vulnerability

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

A shielding panel is introduced as an intermediary between the smartcard and the reader. This panel contains electromagnetic shielding material that blocks unauthorized reading attempts while allowing the card to remain accessible when the shield is positioned away from the card

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The shielding panel is made movable relative to the smartcard through a hinge mechanism. The cardholder can dynamically position the shield to block or allow reading as needed, providing flexible control over when wireless communication is permitted

Inventive Principle:

Principle #15Dynamics

2Reliability

If software encryption is used to protect smartcard data, then data security is improved, but reliability of protection decreases due to potential compromise

Engineering Contradiction:

Improvedata securityVSAvoidencryption compromise risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent converts the inherent vulnerability of wireless communication into a benefit by making the shielding mechanism user-controlled. The same wireless capability that enables unauthorized reading also allows convenient authorized reading when the shield is positioned away from the card

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The protective system is segmented into multiple layers: the smartcard itself, the shielding panel with electromagnetic blocking material, and the hinge mechanism. This segmentation allows the shielding function to be separated from the card, enabling flexible deployment and maintaining card functionality when protection is not needed

Inventive Principle:

Principle #1Segmentation

3Object-affected harmful factors

If shielding material is added to prevent unauthorized reading, then security against electromagnetic signals is improved, but device complexity increases

Engineering Contradiction:

Improveelectromagnetic signal blockingVSAvoidshielding device structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The shielding panel is constructed as a thin, flexible structure that can be easily attached to and removed from the smartcard. This reduces the overall complexity compared to rigid, permanent shielding solutions while maintaining effective electromagnetic blocking

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The shielding panel is designed to combine multiple functions: electromagnetic shielding, mechanical attachment to the card, and user interface elements. This integration reduces the number of separate components needed and simplifies the overall device structure

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A device is provided for shielding a contactless smartcard or RFID tag from reading. The device can include a first panel for holding and presenting a contactless smartcard, a second panel comprising a shielding material that prevents unauthorized reading of information when the contactless smartcard is in proximity to or resting on the second panel, and a hinge coupling the first panel and the second panel. The hinge keeps the device closed for preventing unauthorized reading, and open when a force is applied for allowing authorized reading. The contactless smartcard can be inserted between the first panel and the second panel.
