Dual RFID Baggage Tagging System for Theft Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing baggage checking systems using RFID tags are vulnerable to theft due to illegal or unauthorized replacement of tags during baggage transportation, making it difficult to detect stolen baggage.
Innovation Solution
A dual RFID tagging system where a passenger tag and two baggage tags (one inside the baggage and one outside) are used, with a management device comparing the information to verify the authenticity of the baggage and owner, and a warning device is triggered if discrepancies are detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single RFID tag is attached to baggage for identification, then the baggage checking process is simplified and automation is improved, but the system becomes vulnerable to theft through illegal tag replacement
Solution Approach 1:
The single RFID tag is divided into two separate tags: a first RFID tag attached to the exterior of the baggage and a second RFID tag placed inside the baggage. This segmentation ensures that even if one tag is replaced or tampered with, the other tag remains intact and can be used for verification, thus resolving the vulnerability to theft while maintaining automated checking efficiency
Solution Approach 2:
The system implements a nested structure where the second RFID tag is placed inside the baggage (nested within the baggage structure), while the first RFID tag remains on the exterior. This nested arrangement allows the system to verify baggage authenticity by checking both tags, preventing theft through tag replacement while preserving automated processing
2Device complexity
If visual collation of ID tags with redemption tickets is used at baggage reclaim, then simple equipment is required, but the process is time-consuming and error-prone
Solution Approach 1:
The manual visual collation process is replaced with an automated RFID reading system. Readers automatically detect and read the RFID tags on baggage, and the management device automatically compares the tag information with passenger redemption ticket information, eliminating the need for manual visual matching and significantly reducing reclaim time
Solution Approach 2:
The system enables self-service baggage reclaim by automatically performing the identification and verification processes. The RFID readers and management device handle the entire verification process without requiring manual intervention from baggage reclaim staff, thus reducing both time loss and equipment complexity
3Loss of information
If RFID tags are read automatically at departure and arrival airports, then baggage tracking is improved, but the system cannot detect illegal tag replacement during transportation
Solution Approach 1:
By segmenting the identification system into two separate RFID tags (one on the exterior and one inside the baggage), the system can detect theft attempts. If the baggage is stolen and the exterior tag is replaced, the interior tag remains unchanged and will not match the stolen baggage's new tag, allowing detection of the theft
Solution Approach 2:
The management device reads both RFID tags and compares their information with the registered baggage information. This feedback mechanism allows the system to detect discrepancies that indicate illegal tag replacement or theft attempts, thereby improving both tracking accuracy and theft detection capability
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 system effectively prevents theft by ensuring that only genuine baggage and owners are matched, reducing the risk of misplaced or stolen luggage through real-time status monitoring and alerts.
Implementation Method 1
a passenger tag having RFID which wirelessly transmits information about the passenger or baggage
Data Source
AI summary
A baggage keeping system includes a passenger tag, a first baggage tag, a second baggage tag, a reader and a management device. The three tags have RFID, which wirelessly transmits information about the passenger or baggage. The passenger tag is given to the passenger, the first baggage tag is stored in the baggage inaccessibly by a third party and the second baggage tag is attached to the outside of the baggage. The reader reads information about the passenger or baggage from three tags at boarding the departure-side airport and at arriving the arrival-side airport. The management device registers the information about the passenger and baggage, wirelessly received from the reader, compares the wirelessly received the information, determines whether the information about the passenger and baggage matches each other or not, and when they match, are the genuine baggage and the genuine owner.
