Mobile Device Credit Issuance via Wallet Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for mobile devices to pay for goods and services lack efficient systems for providing and utilizing credits, vouchers, or coupons, especially in point-of-sale transactions, and do not effectively integrate advertising sponsorship models.
Innovation Solution
A system that allows mobile devices to receive and utilize credits via a communications network, incorporating a billing system, wallet service server, and issuer to manage and deliver monetary value codes, which can be sponsored by advertisers, enabling users to purchase goods and services while potentially receiving advertisements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mobile devices are used for point-of-sale transactions using NFC capabilities, then payment functionality is enabled, but the system lacks integrated credit provision and advertising sponsorship mechanisms
Solution Approach 1:
The mobile device is designed to perform multiple functions: it serves as a payment instrument via NFC, a credit storage device, an advertising interface, and a communication terminal. The system integrates billing, wallet services, and advertising sponsorship capabilities into a single unified platform, allowing one device to handle diverse operations without requiring separate specialized systems for each function.
Solution Approach 2:
A wallet service server acts as an intermediary between the mobile device, billing system, and advertising sponsors. This intermediary component manages the complex interactions by coordinating credit issuance, tracking advertising sponsorship, and facilitating transactions, thereby reducing the complexity burden on the mobile device itself while enabling integrated functionality.
2Productivity
If credits are provided to users via mobile devices, then purchasing capability is enhanced, but the system does not effectively integrate advertising sponsorship models
Solution Approach 1:
The system merges advertising sponsorship with credit provision by allowing advertisers to sponsor credits that are loaded onto mobile devices. The billing system tracks both the credit balance and the associated advertising sponsorship, combining commercial advertising functions with financial transaction functions into a single integrated workflow that simultaneously delivers value to users and generates revenue for advertisers.
Solution Approach 2:
The system implements feedback mechanisms where the billing system monitors credit usage and advertising sponsorship status, then provides feedback to both the mobile device and advertisers. This enables dynamic adjustment of credit provision based on advertising sponsorship levels and usage patterns, creating a self-regulating system that balances purchasing capability with advertising integration.
3Reliability
If a billing system and wallet service server are implemented, then credit management is improved, but system complexity increases
Solution Approach 1:
The credit management system is segmented into distinct functional modules: a billing system that handles credit issuance and tracking, a wallet service server that manages mobile device accounts, and a point-of-sale system that processes transactions. Each module operates independently with well-defined interfaces, improving reliability through specialized functionality while managing overall system complexity through modular architecture.
Solution Approach 2:
The system uses digital copies of credit information stored in the mobile device's wallet, eliminating the need for physical cash or traditional card-based systems. The billing system and wallet service server maintain synchronized digital records that can be accessed and updated in real-time, improving reliability through consistent data management while reducing physical system complexity.

AI summary
System and method for delivering upon request credits having monetary value to a mobile device using a communications network. An account of available credit for the user of the mobile device is maintained and authorization to issue credit is generated when a request for credit for the mobile device is received and there is available credit in the account associated with the mobile device equal to or greater than the requested credit. Credit may be sponsored by one or more sponsors and issued to the user, upon authorization, to enable the user to use the mobile device to purchase items, e.g., at a point of sale terminal.
