RFID Digital Token Access Verification via Short-Range Wireless
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for verifying access rights to resources, such as entry to events, rely on optically scanned codes that can be easily reproduced, lacking security and efficiency.
Innovation Solution
A system that uses digital tokens stored in user devices or RFID chips to facilitate entry, transmitting access-right data over short-range communication channels to a client agent device, eliminating the need for optical scanning and enhancing security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If optical scanning codes are used for access verification, then ease of operation is improved, but security deteriorates due to easy reproduction
Solution Approach 1:
The patent replaces optical codes with digital tokens stored in RFID chips. These digital tokens are transmitted wirelessly to mobile devices for verification, eliminating the need for physical code scanning. The digital format prevents easy reproduction while maintaining ease of use through automatic wireless communication and location-based verification.
Solution Approach 2:
The patent substitutes the mechanical optical scanning system with a wireless communication system using RFID and mobile devices. Access verification transitions from physical code scanning to electronic signal transmission and processing, enabling secure digital token verification without manual intervention.
2Reliability
If digital tokens with location-based transfer are used, then security is improved, but device complexity increases
Solution Approach 1:
The system automatically detects user location through GPS or wireless network and verifies access rights without manual intervention. The mobile device autonomously handles token verification, location checking, and access control, reducing the need for complex manual management systems while maintaining high security.
Solution Approach 2:
The mobile device serves multiple functions: storing digital tokens, determining location, verifying access rights, and controlling physical access. This multi-functionality consolidates what would otherwise require separate complex systems into a single universal device, reducing overall system complexity.
3Reliability
If location-based access control is implemented, then security is improved, but loss of time increases due to verification processes
Solution Approach 1:
Access rights are pre-attached to digital tokens before the user arrives at the location. When the user approaches, the system already has the verification data ready and automatically initiates the verification process, eliminating delays associated with manual code scanning or on-site verification procedures.
Solution Approach 2:
The verification process operates continuously in the background as the user moves through the location. Location-based verification triggers automatic token validation without interrupting the user's movement or requiring explicit verification actions, maintaining continuous access control without time loss.
