Transit Access Control Logic for Payment Risk Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of open-loop bank cards as fare media in transit systems often results in delays at access control points due to the time required for payment authorization, and there is a risk of non-payment for transit services, as existing systems cannot accurately determine the likelihood of payment authorization before granting access.
Innovation Solution
Implementing advanced decision logic that accesses historical transaction data from various information sources, such as financial institutions, employers, and government systems, to determine whether to grant access based on the likelihood of payment, reducing the need for real-time authorization checks and minimizing payment risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If real-time payment authorization is performed for open-loop bank cards at access control points, then payment security is improved, but transit user throughput and convenience deteriorate due to several seconds of authorization delay
Solution Approach 1:
The system performs preliminary actions by accessing information sources (historical transaction data, credit bureau data, employer data, government systems) before the user reaches the access control point. This pre-screening process identifies high-risk cards in advance, allowing the system to prepare authorization decisions beforehand, thus eliminating delays at the access control point while maintaining security.
Solution Approach 2:
The patent extracts the authorization decision-making process from the access control point itself. By separating the information gathering and risk assessment functions from the physical access control point, the system can perform comprehensive checks remotely and only present approved cards at the access control point, eliminating the need for real-time authorization delays at the point of access.
2Ease of operation
If access is granted without real-time authorization for declined cards, then user convenience is improved, but payment risk increases
Solution Approach 1:
The system implements feedback mechanisms by continuously monitoring transaction outcomes and updating risk profiles. When a card is initially declined, the system checks information sources to determine if the decline was temporary or permanent. Successful subsequent transactions provide positive feedback that reinforces the card's approved status, while failed transactions trigger re-evaluation, thus dynamically adjusting access decisions based on actual payment behavior.
Solution Approach 2:
The system performs preliminary risk assessment by accessing information sources before granting access to cards with prior declines. This pre-authorization check evaluates whether the card has been restored to good standing through external information sources, allowing the system to make informed decisions about granting access without requiring real-time authorization at the access control point.
3Reliability
If comprehensive information sources are accessed to evaluate payment likelihood, then payment risk management is improved, but system complexity and processing time increase
Solution Approach 1:
The patent segments the information gathering process into distinct, modular components: historical transaction data retrieval, credit bureau data access, employer system queries, and government system checks. Each information source is accessed independently through dedicated interfaces, allowing the system to manage complexity by handling each data source separately rather than as a monolithic process.
Solution Approach 2:
The system introduces intermediary components that facilitate communication with external information sources. These intermediaries handle the complexity of interfacing with different data sources (credit bureaus, employers, government systems) by providing standardized access methods and data formats, thus shielding the core access control logic from the complexity of multiple external systems.
Data Source
AI summary
Techniques are disclosed for determining whether to grant a user access at an access control point of a transit system based on information about a user associated with a fare media from one or more information sources. These techniques can include receiving an authorization response after attempting to authorize payment from a fare media, and accessing at least one information source. This can include accessing historical information regarding prior transactions in the transit system made with the fare media. A determination can then be made whether to grant a user access at the access control point of the transit system.
