Access Control System Using Dual-Identifier Personal Information Carrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access control methods for automatic cycle provision services require users to carry multiple coded information carriers, such as electronic or magnetic cards, which is impractical.
Innovation Solution
An automatic access control system that registers users with a first identifier and associates them with a personal information carrier bearing a second identifier, allowing selective access using contactless reading technologies like RFID or NFC, enabling users to access cycles with a single compatible information medium.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users are registered with multiple coded information carriers, then access control reliability is improved, but user convenience and ease of operation deteriorate
Solution Approach 1:
The patent applies universality by enabling a single personal information carrier to serve multiple functions: it contains both a stable second identifier for reliable identification and a first identifier for initial registration. The system can process different identifier types through the same carrier, eliminating the need for users to carry multiple separate cards while maintaining access control reliability.
Solution Approach 2:
The patent merges the functions of multiple information carriers into a single personal information carrier. By combining the first identifier (for initial registration) and the second identifier (for subsequent access) into one carrier, the system resolves the contradiction between reliability (which previously required multiple carriers) and user convenience (which suffers with multiple carriers).
2Measurement precision
If multiple coded information carriers are used, then identification accuracy is improved, but device complexity and loss of substance increase
Solution Approach 1:
The personal information carrier is designed with universal functionality to provide both first and second identifiers, eliminating the need for multiple separate carriers. This single carrier maintains identification accuracy through its dual-identifier structure while reducing the quantity of information carriers from multiple cards to just one.
Solution Approach 2:
The patent combines multiple identification functions into a single information carrier. The first identifier enables initial registration and the second identifier enables subsequent access, merging what previously required separate carriers into one unified device, thus reducing the number of carriers while preserving identification accuracy.
3Ease of operation
If contactless reading technology is used, then ease of operation is improved, but measurement precision may deteriorate
Solution Approach 1:
The patent uses contactless reading technology to read identifiers from the personal information carrier without physical contact. This copying method maintains reading accuracy by using electromagnetic fields (RFID/NFC) to transfer data wirelessly, while significantly improving ease of operation as users simply need to present their carrier near the reader without insertion or physical interaction.

AI summary
An access control method in which a user is registered and given a first identifier. The user then identifies themselves with this first identifier and has an automatic reading device (11) read a coded personal information storage device (21, 22) bearing a second identifier. The user is then associated with the second identifier. Subsequently, the user identifies themselves by having the personal information storage device read by the automatic reading device, and then a control device (15) is activated based on the reading of the personal information storage device.
