RFID Tag Access Control Through User-Removable Covers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current RFID tag applications lack user control over data activation and deactivation, leading to untimely or unauthorized interrogation, which hampers efficient inventory and supply chain management.
Innovation Solution
A user-controlled mechanism is introduced to selectively deactivate, activate, or reconfigure RFID tags using a cover or material to encapsulate sensors, allowing manual control over data exchange and enabling next-step data actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If RFID tags are continuously active for tracking and monitoring products, then inventory management efficiency is improved, but unauthorized or untimely interrogation occurs leading to data security issues
Solution Approach 1:
The patent applies preliminary action by implementing a cover mechanism that pre-prevents unauthorized interrogation before it can occur. The cover is positioned to block the RFID tag from reader signals in advance, and only when the cover is removed (indicating authorized access or proper timing) does the tag become active for legitimate tracking and data exchange.
2Reliability
If RFID tags are always accessible for data exchange, then supply chain monitoring is continuous, but user control over data activation is lost
Solution Approach 1:
The patent applies dynamics by making the RFID tag's accessibility dynamic rather than static. The cover mechanism allows the tag to switch between active and inactive states based on user action. When the cover is in place, the tag is protected and inactive; when the cover is removed, the tag becomes active and accessible for legitimate supply chain monitoring, thus providing user control while maintaining monitoring continuity.
3Reliability
If RFID tags are deactivated to prevent unauthorized access, then data security is improved, but inventory tracking efficiency decreases
Solution Approach 1:
The patent applies periodic action by implementing intermittent activation of the RFID tag through the cover mechanism. The tag alternates between protected/deactivated states and active states for legitimate interrogation. This periodic activation pattern maintains security during most times while allowing efficient tracking during authorized periods, thus resolving the contradiction between security and tracking efficiency.
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 data communication and management efficiency by providing user-controlled data activation, improving inventory and supply chain management through automated and reliable service platforms.
Implementation Method 1
RFID uses electromagnetic energy to stimulate a tag to self-identify or to provide other stored, collected or generated data
Implementation Method 2
a near-field coherent sensing application can direct electromagnetic energy or radio wave pulse sensing into a body, tissue, product or object using a tag that can be interrogated by a reader to receive generated or pulsed data
Data Source
AI summary
A system and method to provide user marketing recommendations or suggestions based on an interaction between a user and a product, using a radio frequency tag in communication with the product, a radio frequency reader, and a computing device. A motion of the user detected by the radio frequency tag is used to generate a signal containing level of motion, which is utilized by the computing device to determine a level of user interaction and generate marketing information. Marketing information about how to use the product in a recipe is sent to the user interface device.
