ETCS Terminal Card Management via Server-Side Issuance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic toll collection systems (ETCS) face challenges in managing cards for payment transactions, particularly in issuing and deleting cards securely and efficiently within ETCS terminals, which can lead to structural restrictions and theft risks associated with physical credit cards.
Innovation Solution
A server system with a communicator and controller is implemented to manage card issuance and deletion in ETCS terminals by requesting card information from a card company server, transmitting security and authorization keys, and creating or deleting supplementary security domains and applets on the card integrated circuit chip, ensuring secure and efficient card management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a physical credit card is inserted into an ETCS terminal for payment, then the payment function can be performed, but structural restrictions and theft risks occur
Solution Approach 1:
The patent extracts the card functionality from the physical credit card and embeds it directly into the ETCS terminal through a card IC chip. The card information is issued to the terminal itself, separating the payment function from the physical card medium, thereby eliminating theft risks associated with physical card handling while maintaining payment capability
Solution Approach 2:
The patent introduces a server as an intermediary between the card company and the ETCS terminal. The server manages card issuance, stores card information securely, and controls the provisioning of payment functions to terminals. This intermediary layer enhances security by preventing direct exposure of sensitive card data and eliminating the need for physical card insertion
2Reliability
If card information is embedded in the ETCS terminal to prevent theft, then security is improved, but card management complexity increases
Solution Approach 1:
The server performs multiple functions within a single system: it stores card information, manages issuance to terminals, handles deletion requests, and provides security key management. This multi-functional approach consolidates what would otherwise require separate systems, managing complexity through functional integration rather than proliferation of components
Solution Approach 2:
The system implements feedback mechanisms where the server receives confirmation from terminals about successful card issuance or deletion, and card companies can request card deletion through the server. This feedback loop ensures proper state management and allows centralized control over distributed terminal cards, simplifying management through coordinated communication
3Reliability
If a server manages card issuance and deletion centrally, then security and control are improved, but system complexity increases
Solution Approach 1:
The patent merges card issuance, card information storage, deletion management, and security key management into a single centralized server. This consolidation reduces the number of separate systems needed and simplifies the overall architecture by combining multiple card management functions into one unified platform, thereby managing complexity through integration
Data Source
AI summary
A server includes a communicator; and a controller configured to control the communicator. The controller is configured to: in response to receiving a card issuance request from a user terminal through the communicator, control the communicator to request a card company server corresponding to the card issuance request for card information; and in response to receiving the card information from the card company server through the communicator, control the communicator to transmit a card issuance command including a security key and the card information to an electronic toll collection system (ETCS) terminal of a vehicle.
