Contactless Card Actuation Structure for Unauthorized Read Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Contactless cards are vulnerable to unauthorized access as individuals can obtain identification information by bringing a card reader into close proximity with the card without the owner's knowledge, leading to potential theft and unauthorized transactions.
Innovation Solution
Incorporating an actuation structure within the contactless card that requires user activation before identification information can be accessed, featuring a loop antenna and conductive layers that are electrically isolated in a resting position and connected in an actuated position, preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the contactless card includes a loop antenna and integrated circuit that are always electrically connected, then the card can be read by a contactless card reader at any time, but the card becomes vulnerable to unauthorized access and identify theft
Solution Approach 1:
The patent implements an actuation structure that must be activated before the loop antenna becomes electrically connected to the integrated circuit. This preliminary action (user activation) ensures that the card is only readable when intentionally enabled by the user, preventing unauthorized access while maintaining contactless reading capability when needed.
Solution Approach 2:
The actuation structure serves as an intermediary component between the loop antenna and the integrated circuit. When in the unactuated state, this intermediary physically or electrically isolates the antenna from the circuit, blocking unauthorized readings. When actuated, it establishes the electrical connection, allowing legitimate contactless transactions.
2Object-affected harmful factors
If the actuation structure requires user activation to enable reading, then unauthorized access is prevented, but the device complexity increases
Solution Approach 1:
The actuation structure utilizes flexible, thin-film components that can be easily integrated into the card's existing layered structure. This approach minimizes added complexity by using materials and structures similar to those already present in contactless cards, rather than introducing bulky or complex mechanical mechanisms.
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
Enhances security by ensuring that identification information is only accessible when the card is intentionally actuated by the owner, reducing the risk of accidental or unauthorized access.
Implementation Method 1
The antenna may emit a signal such as a radio frequency that is detectable by a contactless card scanner
Implementation Method 2
The first end of the first conductive layer and the second end of the second conductive layer are at and in a first elastically deformable region at a first side of the contactless card

AI summary
The present disclosure is directed to a contactless card including an actuation security structure that is actuated to provide authorization in accessing identifying information on an integrated circuit within the contactless card. In at least one embodiment, the actuation security structure includes a pair of conductive layers and a pair of electrodes. Ends of the pair of conductive layers overlap respective ones of the pair of electrodes. The ends of the pair of conductive layers are at and in a first elastically deformable region and the respective ones of the pair of electrodes are at and in a second elastically deformable region. An owner of the contactless card may provide authorization to access the identification information on the contactless card by applying force to both the first and second elastically deformable regions inward resulting in the ends of the conductive layers moving into electrical communication with the pair of electrodes.
