Value Transfer Card Multi-Currency Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Value transfer cards are limited in their functionality as they are typically associated with a single account, restricting cardholder control over transactions and limiting the ability to manage foreign currency transactions effectively, as the exchange rate is only known after the transaction is processed.
Innovation Solution
A computing system that configures a value transfer card to be associated with multiple currency accounts, allowing authorized entities to select foreign currency accounts and apply card control settings, enabling real-time processing of transactions by querying an exchange rates database to handle transactions in compliance with set limits and restrictions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a value transfer card is associated with a single account, then the system complexity is reduced and ease of operation is improved, but the adaptability and versatility of the card are limited
Solution Approach 1:
The patent implements multi-functionality by enabling a single value transfer card to be associated with multiple currency accounts simultaneously. The card can access and transact across different currency accounts (e.g., USD account, EUR account, GBP account) without requiring separate cards for each currency, thereby achieving universal access and enhanced adaptability while maintaining a single card interface for the user.
Solution Approach 2:
The patent applies segmentation by separating the card from the accounts it accesses. Instead of one card being permanently bound to one account, the system segments the association into a configurable relationship where a single card can be dynamically linked to multiple accounts. This segmentation allows flexible assignment of different currency accounts to the same card, improving versatility without proportionally increasing system complexity.
2Adaptability or versatility
If a value transfer card is configured to access multiple currency accounts, then adaptability and versatility are improved, but device complexity and difficulty of operation increase
Solution Approach 1:
The system implements self-service by automatically determining which currency account to use based on the transaction context. When a transaction is initiated, the system autonomously identifies the appropriate currency account associated with the card and processes the transaction without requiring the user to manually select an account. This reduces the operational burden on the user while maintaining multi-account capabilities.
Solution Approach 2:
The patent applies preliminary action by pre-configuring multiple currency accounts to be associated with the value transfer card before transactions occur. The system establishes the card-to-account relationships in advance, so when a transaction is needed, the appropriate account is already identified and ready for use. This eliminates the need for real-time account selection during transactions, simplifying the user interface and improving ease of operation.
3Measurement precision
If exchange rate information is obtained after transaction processing, then system complexity is reduced, but loss of time and measurement precision are worsened
Solution Approach 1:
The system applies preliminary action by obtaining exchange rate information before transactions are processed. When a card is configured to access multiple currency accounts, the system retrieves the current exchange rates for all associated currencies in advance. This pre-fetching of exchange rate data ensures that accurate, up-to-date rates are available when needed for transaction processing, eliminating delays that would occur if rates were fetched after the transaction is initiated.
Solution Approach 2:
The system implements feedback by continuously monitoring and updating exchange rate information for all currency accounts associated with the card. The system maintains current exchange rate data through ongoing queries to external sources, ensuring that the most accurate and recent rates are available for transaction processing. This feedback mechanism allows the system to provide precise exchange rate information without significantly increasing transaction processing time, as the rates are already cached and ready when transactions occur.
Data Source
AI summary
A processor-implemented method is disclosed. The method includes: configuring, by a processor, a value transfer card to be associated with a default currency account and one or more foreign currency accounts; receiving, by the processor, input including a selection of at least one of the one or more foreign currency accounts and a card control setting to be applied for the value transfer card in connection with the selected at least one foreign currency account; detecting, by the processor, a first transaction initiated using the value transfer card, wherein the detecting includes receiving a request to process the first transaction in a first currency associated with the selected at least one foreign currency account; determining, by the processor in real-time, that the first transaction results in violation of the card control setting for the value transfer card; and in response to determining that the first transaction results in violation of the card control setting for the value transfer card: querying, by the processor in real-time, an exchange rates database to obtain a current exchange rate between the first currency associated with the selected at least one foreign currency account and a second currency associated with a second one of the currency accounts; and processing the first transaction using the second currency account and the current exchange rate.
