Universal Prepaid Card System for Location-Based Transaction Triggering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prepaid cards require customers to load funds in advance, limiting their immediate use and flexibility, as funds are tied to specific purchases and cannot be used for other purposes until loaded, leading to issues with unused balances being abandoned and not easily retrievable by the customer.
Innovation Solution
A universal prepaid card system that allows merchants to maintain a shared funding source, enabling multiple customers to use a single prepaid card for transactions, with funds being provided on an as-needed basis and linked to a merchant location, allowing for secure and convenient payment processing without the need for customers to actively participate in each transaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If funds are loaded onto the prepaid card in advance, then the card can be used for purchases without cash or credit risk, but the funds cannot be used for other purposes and may be abandoned if not spent
Solution Approach 1:
The prepaid card system is segmented into multiple virtual accounts within a single card, allowing funds to be divided into different pools. Each pool can be designated for specific purposes or left general, enabling both secure prepaid transactions and flexible fund allocation. The system separates the card physical structure from the fund management logic, allowing dynamic reconfiguration of fund availability.
Solution Approach 2:
The system dynamically adjusts fund availability and card balances in real-time based on transaction needs. Virtual accounts can be activated or deactivated, and funds can be reallocated between purposes without physical card changes. The card adapts its functionality based on merchant type, transaction amount, and customer preferences, transforming from a static prepaid instrument to a dynamic payment tool.
2Ease of operation
If customers load maximum funds onto the prepaid card to ensure sufficient purchasing power, then they can make any purchase, but unused funds are abandoned and cannot be retrieved
Solution Approach 1:
The system automatically recovers unused funds from virtual accounts through various mechanisms. When a card is deactivated or expires, remaining balances are automatically transferred back to the customer's bank account or retained in the system for future use. The system recovers abandoned funds by offering promotions, allowing transfer to other cards, or automatic rollover to the next billing cycle, ensuring no value is lost.
Solution Approach 2:
The system provides continuous feedback to customers about their remaining balances across different virtual accounts. Through mobile apps, SMS notifications, or in-card displays, customers are informed of unused funds and prompted to utilize them before expiration. The system offers real-time balance information and alerts customers when funds are running low, enabling informed spending decisions and preventing complete abandonment of usable balances.
3Adaptability or versatility
If a single prepaid card is shared among multiple customers, then card availability and convenience are improved, but tracking and control of individual transactions become more complex
Solution Approach 1:
The prepaid card is designed as a universal instrument that can serve multiple customers and purposes simultaneously. A single card number can be associated with multiple virtual accounts, each trackable by the system. The card functions as both a shared payment tool for convenience and an individually accountable instrument through digital tracking, eliminating the need for separate physical cards for each user while maintaining full transaction visibility.
Data Source
AI summary
A computer system can implement a network transaction service by monitoring location data from a computing device of a user to confirm that the user is located at a merchant location, receiving transaction data from a point-of-sale terminal of the merchant location, and confirming that the user has left the merchant location based on the location data. The computer system may then automatically execute a transfer operation to fund the transaction using a shared funding account of the network transaction service such that no direct payment interaction is made between the user and the merchant.
