ID Card Data Sheet Plate Connecting Element Forgery Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data sheets for passport booklets, where the plate is connected with a flexible strip, are vulnerable to forgery as the plate can be separated from the strip without damage, allowing for easy replacement, which complicates detection of tampering.
Innovation Solution
Incorporating weakened material, such as incisions or scratches, in the connecting element, which tears when attempting to detach the plate, making it difficult to separate without damage and rendering the forged passport unusable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the plate is firmly connected to the connecting element through lamination, then the connection strength is improved, but the plate can still be separated without damage allowing forgery
Solution Approach 1:
The patent changes the physical parameter of the connecting element by introducing material weaknesses (incisions or scratches) that alter its structural integrity. These weaknesses are positioned so that when force is applied to separate the plate, the connecting element tears at these predetermined points rather than allowing clean separation, thus preventing forgery while maintaining normal connection strength during legitimate use.
Solution Approach 2:
The patent converts the potential harm of a weak connection (which could allow separation) into a benefit by strategically placing material weaknesses that cause controlled tearing. The incisions or scratches are designed to fail in a specific way that leaves visible damage, transforming what could be a connection weakness into a security feature that prevents undetected plate replacement.
2Reliability
If the connecting element is made with material weaknesses (incisions or scratches), then the anti-forgery security is improved, but the connecting element may tear during normal use
Solution Approach 1:
The patent applies local quality by creating material weaknesses only in specific locations within the connecting element, not throughout the entire structure. The incisions or scratches are positioned in areas where they will be engaged during attempted plate separation, while other areas of the connecting element maintain full structural strength for normal handling and attachment functions.
Solution Approach 2:
The patent performs preliminary action by pre-positioning the material weaknesses (incisions or scratches) during manufacturing. These weaknesses are prepared in advance at specific locations and orientations so that when force is applied during a forgery attempt, the tearing occurs predictably at these predetermined points rather than randomly throughout the connecting element.
3Difficulty of detecting and measuring
If multiple material weaknesses are provided in the connecting element, then the detection of tampering is improved, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the material weakness feature into multiple discrete incisions or scratches distributed along the connecting element. Each incision acts as an independent weakness point that can tear and provide detection capability. This segmentation allows the security feature to be implemented through simple geometric cuts rather than complex integrated structures, maintaining manufacturing simplicity while improving detection reliability.

AI summary
The data sheet includes a plate (2) that can be personalized or is personalized on at least one side. The plate (2) can be bound into the ID card by means of a band-shaped flexible connecting element (3). The connecting element (3) is firmly connected to an edge (4) of the plate (2) by means of a connection (5). The band-shaped connecting element (3) has at least one material weakening (6) that makes it difficult to detach the plate (2) from the connecting element (3) without damage. The material weakening (6) is, for example, a cut or an incision in the connecting element (3). The invention increases the counterfeit protection of ID cards that have such a data sheet (1).
