Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current identity recognition systems, particularly ID cards, face high production costs due to the use of RFID technology and magnetic stripes, which also suffer from degradation issues and require physical contact for data reading.
Innovation Solution
An ID card system utilizing a card case with a plurality of conductor electrodes arranged in a specific pattern, where the positions or connections of these electrodes are sensed by a surface-shaped sensor, such as a capacitive or electric field sensor, to determine the ID without the need for physical contact, reducing production costs and eliminating degradation concerns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RFID technology is used for ID card identification, then identification capability is improved, but production cost increases
Solution Approach 1:
The patent extracts the identification function from complex RFID systems and implements it using simple conductor electrode patterns on the card that interact with a sensor array in the reader. This removes the need for expensive RFID components while maintaining identification capability through spatial pattern recognition.
Solution Approach 2:
The patent replaces expensive, complex RFID tags with inexpensive conductor electrode patterns that can be easily manufactured on standard cards. The conductors serve as a simple, low-cost alternative to electronic RFID components, achieving identification through their physical arrangement rather than active electronics.
2Reliability
If magnetic stripe technology is used for ID card identification, then identification capability is improved, but device complexity increases
Solution Approach 1:
The patent replaces the mechanical swiping mechanism required by magnetic stripe readers with a non-contact sensing system. The sensor array detects the conductor patterns through proximity or contactless interaction, eliminating the need for mechanical movement and complex reader mechanisms.
Solution Approach 2:
Instead of having the card actively present information to the reader (as with magnetic stripes that must be swiped), the patent inverts the approach by having the reader's sensor array actively sense the passive conductor patterns on the card. This reverses the interaction model and simplifies the reader's mechanical requirements.
3Reliability
If magnetic stripe is used for ID card identification, then identification capability is improved, but reliability deteriorates over time
Solution Approach 1:
The patent uses simple conductor electrodes that are inherently more durable than magnetic stripes. These conductors are less susceptible to degradation from repeated use, environmental factors, and physical wear, providing a more reliable identification medium that maintains its properties over time without the degaussing issues of magnetic stripes.

Function Achieved in This Case
This solution allows for cost-effective production and reliable identification of ID cards, as the conductor electrodes can be easily arranged and recognized by sensors, enhancing security and reducing the risk of physical wear and tear.
Implementation Method 1
the surface-shaped sensor determines the specific ID of the ID card according to the position of the specific conductor electrode sensed by the surface-shaped sensor
Implementation Method 2
the system senses the positions of the conductors or senses the pattern by the electrical connections of the conductors to identify the specific ID of the ID card

AI summary
A system for identifying identity (ID) and an ID card using the same are provided in the present invention. The ID card utilizes a specific ID reader to identify the ID of the ID card. The ID card includes a card case, a plurality of disposing positions for electrodes and at least a specific conductor electrode. The disposing positions are disposed in the card case. The specific conductor electrode(s) is/are disposed on at least one of the disposing positions according to the ID of the ED card. The specific card reader includes a flat panel sensor. When the ID card is close to the flat panel sensor of the card reader, the flat panel sensor senses the position of the conductor electrode(s) to determine the ID of the ID card.
