Mobile Payment Method Using Real-Time Server Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional contactless stored value smart cards lack secure authentication and timely payment processing, leading to potential fraud and mismatched transaction records, which expose merchants to loss.
Innovation Solution
A mobile payment method using Near Field Communication (NFC) or QR code that enables real-time communication between transaction and payment devices with a payment institution server, ensuring secure and timely payment processing by verifying payment information and generating a payment request for immediate processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If batch settlement is used for payment processing, then transaction records are stored at the merchant without immediate transmission, but this increases the risk of mismatched records and potential loss
Solution Approach 1:
The system performs preliminary actions by transmitting transaction records immediately after each purchase rather than waiting for batch settlement. The mobile payment terminal sends transaction data to the server in real-time, enabling immediate verification and reducing the window for potential fraud or mismatches.
Solution Approach 2:
The system implements feedback mechanisms where the server immediately processes and verifies transaction records upon receipt. The server sends confirmation responses back to the mobile payment terminal, creating a closed-loop feedback system that ensures real-time validation and reduces reliance on end-of-day batch settlement.
2Ease of operation
If conventional contactless smart cards are used without authentication, then payment convenience is maintained, but card authentication security is insufficient
Solution Approach 1:
The system introduces a server as an intermediary between the mobile payment terminal and the payment processing system. The server receives transaction records, performs authentication verification, and validates transaction data, acting as a trusted mediator that enhances security without requiring changes to the convenient contactless payment interface.
Solution Approach 2:
Authentication verification is performed preliminarily by the server before finalizing the transaction. The system pre-validates transaction records and verifies card authentication data in real-time, preventing fraudulent transactions before they are completed, thus maintaining convenience while enhancing security.
Data Source
AI summary
A mobile payment method is to be implemented by a transaction device, and includes: receiving payment information, transmitting the payment information to a payment institution server, providing the payment information to a payment device, and receiving a payment result. The payment device is enabled to generate a payment request when the payment institution server determines that the payment information received from the payment device conforms to the payment information received from the transaction device, and to transmit the payment request to the payment institution server for subsequent processing of the payment according to the payment information included in the payment request.
