One-Time Transaction Identifier for Cash-Based Online Payments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unbanked users lack a method to conduct online transactions using currency, as they do not have a bank account or payment card.
Innovation Solution
A system that generates a one-time identifier for a transaction, allowing unbanked users to complete online transactions using physical or digital currency by associating an authorization request message with an identifier request message using the one-time identifier, and facilitating transaction completion through a server computer and resource provider computer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If unbanked users want to conduct online transactions, then accessibility to online commerce is improved, but the requirement for bank accounts or payment cards creates a barrier that worsens accessibility for unbanked users
Solution Approach 1:
The patent introduces a server computer as an intermediary that generates one-time identifiers and processes authorization requests. This intermediary system bridges the gap between unbanked users with currency and online merchants, enabling transactions without traditional banking infrastructure. The server acts as a mediator that converts physical currency into digital transaction credentials through the one-time identifier mechanism.
Solution Approach 2:
The patent creates a digital copy or representation of physical currency through one-time identifiers. Instead of requiring users to have digital wallets or bank accounts, the system generates unique digital tokens that represent value, allowing unbanked users to transact by presenting these copied value representations at access devices.
2Adaptability or versatility
If a system is created to allow unbanked users to transact with currency, then inclusivity is improved, but the system complexity increases due to needing new infrastructure
Solution Approach 1:
The patent makes existing access devices universal by enabling them to process both traditional card-based transactions and new currency-based transactions through the one-time identifier system. The server computer provides a universal interface that works with various access devices without requiring modification to the devices themselves, thus reducing overall system complexity while maintaining inclusivity.
Solution Approach 2:
The system enables self-service functionality where unbanked users can independently convert physical currency to one-time identifiers at access devices without requiring bank staff or intermediaries. The automated server computer handles identifier generation, validation, and transaction processing, reducing the need for complex manual verification infrastructure.
3Reliability
If one-time identifiers are used for transactions, then security is improved through unique transaction tracking, but the processing time increases due to server communication requirements
Solution Approach 1:
The server computer generates and provides the one-time identifier to the access device in advance, before the actual transaction occurs. This preliminary action allows the access device to have the identifier ready for immediate use, reducing processing time during the actual transaction while maintaining security through the unique identifier.
Solution Approach 2:
The patent streamlines the authorization process by having the server computer pre-validate and associate the one-time identifier with the transaction amount and user credentials. During the actual transaction, the system skips lengthy verification steps by directly matching the presented identifier against pre-stored associations, thus maintaining security while reducing processing time.
Data Source
AI summary
Systems and methods of completing transactions with currency are described. One method includes receiving, by a server computer, an identifier request message with a transaction amount for a transaction with a user from a resource provider computer. The server computer sends to the resource provider computer an identifier response message with a one-time identifier. The user provides currency, such as physical currency, and the one-time identifier to an access device, or an operator associated with the access device. The server computer then receives an authorization request message including the transaction amount and the one-time identifier from the access device. The server computer associates the identifier request message with the authorization request message using the one-time identifier and sends, an authorization response message to the access device. The server computer then sends a transaction completion message to the resource provider computer.
