Problem
Current contactless smart cards face challenges in efficiently facilitating transit fare payments due to limitations in data storage, security, and compatibility across multiple transit systems, leading to inefficiencies and increased costs in infrastructure and fraud prevention.
Innovation Solution
A dual-function contactless smart card with dynamic memory management, allowing separate storage regions for commerce transactions and transit applications, ensuring data isolation and flexibility to accommodate multiple transit systems, while maintaining security through encryption and secure data transfer protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single contactless smart card is used for both commerce and transit payments, then card versatility is improved, but data security and system compatibility become more complex
Solution Approach 1:
The contactless smart card employs separate data storage regions: a first region dedicated to commerce transaction data and a second region dedicated to transit fare payment data. This segmentation isolates sensitive payment information from transit-specific information, allowing the card to support multiple functions while maintaining data security and system compatibility independently for each application type.
2Productivity
If contactless smart cards store transit-specific data, then transaction speed is improved, but fraud prevention becomes more difficult
Solution Approach 1:
The card separates commerce data and transit data into different storage regions with independent access controls. Transit-specific data including fare information and transaction records are isolated in the second region, enabling fast contactless transit transactions while preventing unauthorized access to sensitive payment credentials stored in the first region, thus maintaining both speed and security.
Solution Approach 2:
Different security protocols and access restrictions are applied to different data regions. The first region containing commerce data implements stricter security measures for fraud prevention, while the second region containing transit data is optimized for rapid access and transaction processing, allowing each region to have security characteristics matched to its specific functional requirements.
3Reliability
If separate payment cards are used for commerce and transit, then data security is improved, but ease of operation deteriorates
Solution Approach 1:
The patent combines commerce payment functionality and transit fare payment functionality into a single contactless smart card. The card integrates both applications with separate but coexisting data storage regions, allowing users to carry and use one card for both commerce transactions and transit fare payments, thereby improving convenience while maintaining data security through architectural separation.
Solution Approach 2:
The contactless smart card is designed as a universal payment device that can function in both commerce transactions and transit fare payments. By incorporating multiple applications within a single card platform with appropriate data isolation, the card achieves multi-functionality without compromising the security or performance of individual applications.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables seamless and secure use of a single card for both commerce and transit payments across various systems, enhancing transaction speed, reducing infrastructure costs, and improving fraud prevention by isolating sensitive payment data from transit-specific information.
Implementation Method 1
Such contactless cards typically communicate with the card reader or terminal using RF (radio-frequency) technology, wherein proximity to an antenna causes data transfer between the card and the reader or terminal.
Data Source
AI summary
An apparatus such as a mobile phone includes a contactless smart card or payment device, where the smart card is intended for use in both commerce transaction payment and transit fare payment (or other venue access) environments. The payment device may function as both an electronic wallet for commerce transactions and as a transit system card, for access to and fare payment of transit services. Implementation of both functions may be achieved by use of a dynamic memory management system that permits data for both the payment and transit applications to be stored on the card, with the transit data and storage locations isolated from those used to store data intended for use in paying for commerce transactions. The transit application specific data may include access control data (keys, passwords, identification data) or data required for fare calculations (rates, historical data on system use), for example.
