Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current security document verification systems face challenges in accurately reading localized security features across different types of documents, particularly due to varying formats and positions of RFID chips, leading to inefficiencies and errors in authentication processes.
Innovation Solution
A terminal unit with an RFID card reader and type recognition module that automatically identifies the document type and positions the RFID chip for reading, allowing for fully automated verification of security documents, including those with RFID chips in various locations within the document, and incorporates multiple excitation sources and sensors for comprehensive security element evaluation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual orientation and handling of security documents is required, then the verification process can accommodate different document formats, but the verification speed and user-friendliness deteriorate
Solution Approach 1:
The system performs self-identification of document type and automatic positioning of the RFID chip without manual intervention. The type recognition module automatically detects the document format and the drive automatically positions the RFID chip in the reading position, making the system serve itself rather than requiring user orientation and handling
Solution Approach 2:
The system performs preliminary actions by automatically identifying the document type and pre-positioning the RFID chip before the verification process begins. This preliminary automatic positioning eliminates the need for manual orientation and accelerates the verification process
2Adaptability or versatility
If RFID chips are positioned at various locations within different document formats, then the system must handle diverse document types, but the reading accuracy and positioning precision deteriorate
Solution Approach 1:
The system employs a movable drive that dynamically adjusts the position of the RFID card reader to match the RFID chip location. Instead of a fixed reader position, the drive enables real-time repositioning based on the detected RFID chip location, maintaining reading accuracy across diverse document formats
Solution Approach 2:
The system adapts its reading approach to the specific local conditions of each document type. The type recognition module identifies the specific document format and the drive positions the RFID card reader at the appropriate local position for that document type, ensuring precise reading for each specific case
3Loss of time
If large-format documents are verified without double scanning, then the verification time is reduced, but the measurement completeness deteriorates
Solution Approach 1:
The system transitions from a single scanning approach to a multi-dimensional verification approach by incorporating multiple excitation sources (UV, visible, infrared) and corresponding sensors. This enables comprehensive security feature detection in a single pass by examining the document from multiple spectral dimensions simultaneously
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
The solution enables fast, user-friendly, and error-reduced document verification, reducing the need for manual orientation and handling, and allows for the verification of large-format documents without double scanning, enhancing the reliability and efficiency of the authentication process.
Implementation Method 1
an RFID card reader (606), which is designed to read data from an RFID chip (608) of the security document
Implementation Method 2
a first excitation source (502) and a first sensor (510), both of which are part of the upper module, and a second excitation source (504) and a second sensor (512), each of which is part of the lower module. The first and second excitation sources correspond to a first excitation type and are designed to excite at least a first security element (302-306) of the inserted security document during the feeding of the security document. The first and second sensors are designed to receive a first signal during the feeding of the security document if this signal emanates from the excited first security element
