Ticket Re-entry Control Using Printed Memory
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for controlling re-entry into events using admission tickets face challenges in preventing ticket reuse, with existing methods being costly, inflexible, and requiring expensive infrastructure, such as RFID devices, while maintaining privacy and security.
Innovation Solution
The use of printed admission tickets with integrated machine-readable data and re-writeable electronic memory, where user-specific information is stored as a hashed code, allowing for secure verification of ticket authenticity and user identity upon re-entry without the need for a central database connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional re-entry control methods (hand stamps, wristbands, centralized database synchronization) are used, then ticket reuse can be prevented, but infrastructure cost and materials cost increase significantly
Solution Approach 1:
The patent extracts the re-entry control functionality from centralized infrastructure (databases, RFID systems) and embeds it directly into the ticket itself through printed memory. This allows the ticket to store and verify its own re-entry status independently, eliminating the need for expensive centralized systems while maintaining reliable ticket reuse prevention.
Solution Approach 2:
The patent uses inexpensive printed memory on disposable tickets instead of expensive reusable RFID devices or physical wristbands. The printed memory provides sufficient functionality for re-entry control at a fraction of the cost, and the tickets can be discarded after use, eliminating the need for costly infrastructure.
2Reliability
If RFID devices or personalized tickets are used for re-entry control, then security is improved, but materials cost and infrastructure cost increase
Solution Approach 1:
The patent replaces expensive RFID devices and personalized physical tickets with inexpensive printed memory on standard tickets. The printed memory provides the necessary security functionality for storing and verifying re-entry status without requiring costly materials or infrastructure, achieving security at low material cost.
3Reliability
If centralized database synchronization is used for re-entry verification, then ticket authenticity can be verified, but throughput decreases due to connection requirements
Solution Approach 1:
The patent extracts the authenticity verification capability from centralized databases and embeds it directly in the ticket through printed memory. This allows verification to occur locally at the point of re-entry without requiring network connections, maintaining reliable authenticity verification while eliminating throughput limitations imposed by centralized system dependencies.
4Reliability
If hand stamps or physical alterations are used for re-entry marking, then re-entry control is achieved, but flexibility and automation are reduced
Solution Approach 1:
The patent replaces manual mechanical processes (hand stamps, physical ticket alterations) with automated optical reading of printed memory. The system uses machine-readable codes that can be automatically scanned and verified, eliminating the need for manual processing while maintaining reliable re-entry control and enabling full automation of the verification process.

Function Achieved in This Case
This solution provides secure and cost-effective re-entry control by verifying the authenticity of tickets and users, maintaining privacy, and reducing infrastructure costs, while allowing for flexible and efficient re-entry management.
Implementation Method 1
optically read original machine-readable data on the original admission ticket using a machine reader at the location
Data Source
AI summary
During admission to a location, a machine reader optically reads original machine-readable data on an original admission ticket and stores an original code based on the original machine-readable data and original user-specific information in re-writeable electronic memory on the original admission ticket while the original user is entering the location. The original user is then provided initial entry to the location. After the initial entry, a potential admission ticket is received at the location from a potential user. The machine reader optically reads potential machine-readable data on the potential admission ticket at the location, and the machine reader compares a potential code based on the potential machine-readable data and potential user-specific information to the original code stored in the re-writeable electronic memory on the original admission ticket. The potential user is provided re-entry to the location only if the potential code matches the original code.
