RFID Tag Standby Activation for Computing Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Passive RFID tags require continuous proximity to a reader for power and communication, limiting their operational range and independence, especially in applications needing secure access and control without continuous power supply.
Innovation Solution
Embedding an RFID tag in a computing device to enable standby activation using an RFID reader's excitation field for power and communication, allowing secure access and control through modulation of control lines without continuous power, and enabling/disabling power and communication lines for secure operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a passive RFID tag is used to provide power and communication, then the tag can operate without its own power source, but the tag is limited to operation when in contact or near contact with a reader
Solution Approach 1:
The computing device is placed in a standby state with pre-configured activation capabilities before actual use. The RFID tag is embedded and pre-connected to control lines, so that when the reader approaches, the device can be rapidly activated without requiring continuous power or complex initialization procedures.
2Loss of energy
If a passive RFID tag is used for secure access control, then power consumption is reduced, but the device requires continuous proximity to a reader for operation
Solution Approach 1:
The system dynamically transitions between standby and active states based on the presence of the reader. The RFID tag continuously monitors for the reader's excitation field and activates the computing device only when needed, creating a dynamic on-demand operation mode that balances power savings with operational reliability.
Solution Approach 2:
The RFID tag maintains continuous monitoring capability in standby mode to detect the reader's presence, ensuring that the useful action of secure access control is always available when needed. The control lines remain connected and ready, providing continuous potential for activation without continuous full-power operation.
3Reliability
If the computing device is activated using RFID tag with excitation field, then secure access is enabled, but the device requires reader presence for activation
Solution Approach 1:
The mechanical or manual activation process (such as pressing power buttons, entering passwords, or physically connecting power) is replaced with contactless RFID-based activation. The user simply needs to bring the reader near the embedded tag, and the device automatically activates, substituting complex manual procedures with a simple proximity-based mechanism.
