Terminal Balance Insufficiency Handling via Linked Account Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic payment systems on terminals lack efficient mechanisms for handling insufficiencies in shared account balances during transactions, leading to cumbersome processes for users and potential delays in settlement.
Innovation Solution
A terminal-based system that displays balance insufficiency information and allows users to input instructions for settling transactions using either the shared account or a linked account, enabling seamless payment processing by transferring funds from one account to another if the shared account balance is insufficient.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the system uses a shared account for settlement, then multiple users can carry out settlement with the same account, but the balance insufficiency problem arises when the shared account balance is insufficient
Solution Approach 1:
The system performs preliminary balance verification before settlement execution. When the shared account balance is insufficient, the system proactively identifies this condition and triggers a fund transfer request to the linked account in advance, ensuring the settlement can proceed without failure.
Solution Approach 2:
The system introduces a linked account as an intermediary resource to supplement the shared account balance. When the shared account lacks sufficient funds, the linked account acts as a backup source, automatically transferring funds to ensure the settlement transaction can be completed reliably.
2Productivity
If the system automatically transfers funds from linked accounts when shared account balance is insufficient, then settlement can proceed smoothly, but the user may not be aware of the fund transfer and associated charges
Solution Approach 1:
The system implements feedback mechanisms by displaying fund transfer information and charge details to the user before the automatic transfer is executed. The terminal shows the amount to be transferred, the source account, and any associated charges, allowing the user to review and understand the transaction before it occurs.
Solution Approach 2:
The system displays fund transfer information in advance before executing the automatic transfer. This preliminary information presentation ensures users are aware of the upcoming fund movement and associated costs, preventing information loss while maintaining efficient automatic processing.
3Ease of operation
If the system requires user input to select account for settlement, then user control over payment source is improved, but the settlement process becomes more complex and time-consuming
Solution Approach 1:
The system performs preliminary checks to determine whether the shared account has sufficient balance before requiring user input. When the balance is sufficient, the system automatically proceeds with settlement using the shared account without requiring user selection, thus saving time. User input is only required when necessary, balancing control with efficiency.
Solution Approach 2:
The system enables self-service by automatically selecting the appropriate account for settlement based on predefined rules and account configurations. When the shared account has sufficient funds, the system autonomously completes the transaction without user intervention, reducing settlement time while maintaining user control through prior account setup options.

AI summary
A non-transitory computer-readable medium stores instructions which, when executed by at least one processor of a terminal that executes processing relating to payment, cause the at least one processor to perform processing related to a first settlement based on a first account with which a user of the terminal is able to carry out settlement; control a display region of the terminal to display first information related to an insufficiency of a balance of the first account, the first information being based on an amount of the first settlement and the balance of the first account; and based on a first input being received at the display region while the first information is displayed, perform the processing related to the first settlement based on at least a second account different from the first account.
