Conventional RFID systems can only provide limited information about tagged objects, lacking the capability to offer detailed additional information, which is necessary for efficient management and tracking in various applications.
Innovation Solution
A wireless terminal equipped with an RFID reader, a controller, and a communication network interface that requests and receives additional information from an additional information providing server, allowing for the retrieval and display of detailed information associated with RFID tags, using a tag data list and anti-collision algorithms to manage multiple tags.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If RFID tags are used to automatically identify and track articles, then tracking efficiency is improved, but the amount of information provided remains extremely limited
Solution Approach 1:
The system segments information into two parts: basic identification data stored in the RFID tag and detailed additional information stored in a database. The RFID tag contains only essential identification data for quick recognition, while comprehensive information is separated and stored externally, allowing efficient tracking while providing complete information when needed.
Solution Approach 2:
The patent introduces a database as an intermediary between the RFID tag and the information display system. The database acts as a mediator that receives requests from the RFID reader, retrieves detailed information based on tag data, and provides comprehensive information without requiring the RFID tag itself to store all data, thus maintaining tracking efficiency while eliminating information limitations.
2Loss of information
If detailed additional information is provided through a communication network, then information completeness is improved, but communication costs and usage time increase
Solution Approach 1:
The system performs preliminary actions by pre-storing detailed information in a database and pre-establishing the communication infrastructure. When an RFID tag is scanned, the system already has the capability to immediately retrieve and display detailed information without requiring real-time data collection or processing, thus providing complete information while minimizing additional time consumption.
3Ease of operation
If RFID readers are installed in wireless terminals, then information accessibility is improved, but device complexity increases
Solution Approach 1:
The patent makes the wireless terminal universal by integrating multiple functions: the terminal serves as both an RFID reader for identifying tags and as a communication device for accessing the database. This multi-functionality allows the same device to perform identification and information retrieval without requiring separate specialized equipment, thus improving accessibility while managing complexity through consolidation.
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
Enables the provision of detailed additional information about RFID-tagged objects, enhancing tracking and management efficiency by connecting the wireless terminal to a communication network and utilizing a server for additional data, reducing communication costs and usage time.
Implementation Method 1
RFID is a kind of automatic identification and data capture (AIDC) technology reading data from a tag including a microchip using an RF in a non-contact way.

AI summary
A wireless terminal and a radio frequency identification system for providing additional information and a method of providing additional information using the wireless terminal and the radio frequency identification system. The wireless terminal includes: a tag reader reading tag data from a radio frequency identification tag; a controller generating an additional information request signal with respect to the read tag data; and a communication network interface transmitting the additional information request signal through a communication network and receiving additional information with respect to the additional information request signal. Since the controller of the wireless terminal controls the radio frequency identification reader by optimally setting the information required for determining the time point for the radio frequency identification reader tag to respond, and utilizing the stored address of the additional information providing server, the additional information can be efficiently provided.
