Mobile Ticket Validation Using Camera Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic ticketing systems for public transport require extensive infrastructure, including fixed card readers and smart card infrastructure, which is costly and inefficient.
Innovation Solution
Implementing an electronic ticketing system using portable devices like smartphones with near-field communication capabilities, where machine-readable tags replace traditional card readers, allowing passengers to check in and out using their devices, which communicate with a virtual ticketing machine via a network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional smart card readers and fixed card reading infrastructure are used, then ticket validation can be performed, but implementation costs are high and system complexity increases
Solution Approach 1:
The patent replaces physical smart card readers with virtual copies implemented as software applications on mobile devices. The mobile ticketing application replicates the functionality of traditional card readers, allowing ticket validation to be performed through the mobile device's camera and image processing capabilities rather than requiring dedicated hardware readers at every validation point.
Solution Approach 2:
The patent substitutes the mechanical and electronic contact-based smart card reading system with an optical-based system using camera imaging and image processing. Instead of requiring physical contact between card and reader, the system captures images of the ticket and processes them through software algorithms to validate authenticity and extract information.
2Ease of operation
If extensive card reader infrastructure is deployed, then ticket validation is enabled, but implementation and maintenance costs increase
Solution Approach 1:
The patent makes the mobile device itself a universal ticket validation tool that can function across multiple locations and contexts without requiring location-specific hardware infrastructure. The same mobile device with the ticketing application can validate tickets at any point where image capture is possible, eliminating the need for location-specific card reader deployment.
Solution Approach 2:
The system enables users to perform ticket validation themselves using their own mobile devices, eliminating the need for operator-assisted validation at physical ticket gates. The mobile application automatically captures, processes, and validates tickets through the device's camera and integrated software, making the validation process self-service oriented.
3Productivity
If smart card readers are placed on vehicles and at stations, then contactless ticket reading is achieved, but the number of readers required increases system cost
Solution Approach 1:
Instead of placing readers at fixed locations (stations and vehicles) to read passive smart cards, the patent inverts the approach by placing active processing capability in the user's mobile device that captures and processes ticket images. The validation capability moves from the infrastructure side to the user side, eliminating the need for numerous fixed readers.
Solution Approach 2:
The patent transitions from a two-dimensional contact-based reading system to a three-dimensional optical imaging system. Instead of requiring close physical contact between card and reader, the camera-based system can capture ticket information from a greater distance and at various angles, adding spatial flexibility to the validation process.

AI summary
In a ticketing system, machine readable tags are each associated with at least one service. A portable electronic device is configured to read the machine readable tags and to generate an indication of a service used. The portable electronic device is operable to send an indication of a service used via a wireless network to a server. The server is configured to receive the indication and to generate a record of the service used.
