Mobile Gateway Fund Transfer via Internal Account IDs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing use of mobile devices for financial transactions poses challenges in managing funds, as users may conduct transactions based on current balances without considering upcoming automatic payments, leading to unintended depletion of savings accounts. There is a need to keep the user interface simple while preventing premature access to secondary savings accounts.
Innovation Solution
A network and method that allows automatic transfer of funds from a main account to a linked sub-account upon specific triggering transactions, such as deposits or debit transactions, with immediate posting and notification to the user, using a transaction processing system with data structures for main and sub-accounts and internal account IDs to segregate and manage these transfers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automatic funds transfer is posted at the end of the day, then batch processing efficiency is maintained, but real-time balance accuracy deteriorates leading to unintended transactions
Solution Approach 1:
The system performs preliminary actions by posting automatic funds transfers immediately when triggering transactions occur, rather than waiting for end-of-day batch processing. This ensures balances are updated in real-time before consumers can initiate transactions, preventing unintended overdrafts while maintaining simple user interface.
2Ease of operation
If user interface is kept simple, then ease of operation is improved, but visibility and control over sub-accounts deteriorates
Solution Approach 1:
The system extracts sub-account management from the main user interface, keeping it simple for consumers. Sub-accounts are managed separately with internal account IDs, and automatic transfers are initiated based on main account transactions without requiring complex user configuration or visibility of sub-account details.
Solution Approach 2:
The system uses an intermediary mechanism where the mobile gateway and transaction processing system automatically match main account transactions with corresponding sub-account transfers based on transaction types and amounts. This intermediary process occurs transparently without requiring user intervention or complex interface interactions.
3Reliability
If funds are transferred immediately upon triggering transaction, then real-time balance accuracy is improved, but transaction processing complexity increases
Solution Approach 1:
The system changes the timing parameter of funds transfer from end-of-day batch processing to immediate real-time processing. When a triggering transaction is detected, the system immediately posts the automatic funds transfer to the sub-account, ensuring real-time balance accuracy. The complexity is managed through automated matching rules based on transaction types and amounts.
Data Source
AI summary
Users of mobile devices communicate through a mobile gateway to a transaction processing system. The transaction processing system manages accounts, such as debit card accounts, for the users. The accounts include a main account for each user and sub accounts that are linked or related to the main account. Funds may be transferred between a main account and its linked sub accounts, including automatic funds transfer when a transaction (e.g., a payroll deposit from an employer or a debit transaction at a specified retailer) is made against the main account and meets certain parameters established by a user. Access to linked sub accounts is made through use of internal account IDs, rather than the account number of the main account.
