Digital Tag System for Cross-Platform Payment Interoperability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Peer-to-peer applications face interoperability issues and user identification challenges due to the use of different aliases across various applications, limiting their ability to facilitate seamless transactions between users on different platforms.
Innovation Solution
A digital tag system that allows users to send and receive payments by generating a unique identifier linked to their accounts, enabling transactions across different peer-to-peer applications through a digital tag computer that processes transfer requests and messages, ensuring secure and seamless fund transfers without exposing actual account numbers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If different aliases are used to identify users in peer-to-peer applications, then user identification within a single application is simplified, but interoperability between different applications becomes complicated
Solution Approach 1:
The patent introduces a universal identifier system that acts as an intermediary between different peer-to-peer applications. This universal identifier replaces the need for direct compatibility between different application-specific aliases, allowing users to be identified across platforms without requiring each application to understand the others' identification systems.
Solution Approach 2:
The patent creates a universal identifier that can function across multiple different peer-to-peer applications simultaneously. This single identifier system serves multiple functions: it works within individual applications for simple identification and also enables cross-application interoperability, eliminating the need for separate alias systems for each platform.
2Productivity
If account numbers are directly exposed for transactions, then transaction processing is simplified, but security is compromised
Solution Approach 1:
The patent introduces a intermediary layer in the transaction process where the universal identifier system mediates between the user and the actual account number. This intermediary mechanism allows transactions to be processed efficiently using the universal identifier while preventing direct exposure of sensitive account numbers, thus maintaining both productivity and security.
Solution Approach 2:
The patent creates a copy or representation of the account identification function through the universal identifier. Instead of using the actual account number directly in transactions, the system uses this copied identification mechanism that performs the same function of identifying the account for transaction purposes without revealing the sensitive underlying account number.

AI summary
A method is disclosed. The method comprises receiving, by a digital tag computer from a receiver user device a transfer request comprising a digital tag associated with the receiver, a digital tag associated with a sender, and a transfer amount. The method then generates an identifier to be associated with the received transfer request. The digital tag computer then transmits the transfer request to a sender user device associated with the second user, where the transfer request includes the identifier associated with the request. After transmitting the transfer request, the digital tag computer receives a transfer message relating to the transfer request. Then, after receiving the transfer message, the digital tag computer transmits the transfer message.
