Mobile Device Emulating RFID Transponder Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing complexity of securing premises and accessing services has led to individuals carrying multiple physical keys and identification cards, making it cumbersome to manage access and affiliations with various entities.
Innovation Solution
A mobile communication device is equipped with hardware and software to emulate radio frequency identification (RFID) signals, allowing it to act as an active or passive RFID transponder, thereby simplifying the provision and transfer of keys and identifiers using existing communication elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple physical keys and identification cards are carried to access different secured premises and services, then access to various entities is enabled, but device complexity and ease of operation deteriorate due to the burden of managing multiple physical items
Solution Approach 1:
The patent combines multiple identification functions into a single RFID tag that can be read by different readers. Instead of carrying separate physical keys and cards for home, office, parking garage, and loyalty programs, the invention uses one RFID tag containing multiple identifiers that can be selectively activated based on which reader is detecting it.
Solution Approach 2:
The RFID tag is designed with universal functionality to serve multiple purposes. It can provide home access, office access, parking garage access, and loyalty program identification all through a single device. The tag responds to different types of readers (home reader, office reader, garage reader, loyalty reader) with appropriate identifiers.
2Adaptability or versatility
If multiple physical keys and identification cards are carried to access different secured premises and services, then access to various entities is enabled, but ease of operation worsens due to the cumulative burden of carrying and managing items
Solution Approach 1:
The patent combines multiple identification functions into a single RFID tag that can be read by different readers. Instead of carrying separate physical keys and cards for home, office, parking garage, and loyalty programs, the invention uses one RFID tag containing multiple identifiers that can be selectively activated based on which reader is detecting it.
Solution Approach 2:
The invention creates a digital copy of multiple identification credentials within a single RFID tag. Rather than physically carrying separate cards, the RFID tag contains electronic copies of home key, office key, garage remote, and loyalty card information that can be transmitted wirelessly to appropriate readers.
3Ease of operation
If a single RFID tag emulates multiple identifiers, then ease of operation improves by reducing physical items to carry, but device complexity increases due to the need for multiple reader compatibility
Solution Approach 1:
The RFID tag is designed with universal functionality to serve multiple purposes. It can provide home access, office access, parking garage access, and loyalty program identification all through a single device. The tag responds to different types of readers (home reader, office reader, garage reader, loyalty reader) with appropriate identifiers.
Solution Approach 2:
The RFID tag dynamically adapts its response based on which reader is detecting it. When a home reader detects the tag, it provides the home identifier; when an office reader detects it, it provides the office identifier, and so on. This dynamic behavior allows a single static tag to function as multiple different identifiers.
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
This solution reduces the need for multiple physical cards by leveraging mobile devices to emulate RFID signals, enhancing convenience and streamlining access to secured premises and services.
Implementation Method 1
A mobile communication device is equipped with hardware and software to emulate radio frequency identification (RFID) signals
Data Source
AI summary
A mobile communication device is equipped with hardware and/or software components to enable the device to output a data in a form of a radio frequency signal, emulating outputting of the data by either an active or a passive RFID transponder. The data may be a security key or an identifier. Emulation of an active RFID transponder includes facilitating selection of the data and instruction to output by a user. Emulation of a passive RFID transponder includes detecting for proximal presence of a RFID reader. Either case, provision of the data to the mobile communication device may include provision of associated signal attribute(s).
