Payer-Centric Mobile Payment via Intermediary Gateway
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing payment methods risk personal information exposure and credit card skimming, leading to fraudulent activities and unwanted telemarketing, as payers must physically present credit cards for transactions, exposing sensitive information to participating stores.
Innovation Solution
A payer-centric payment system using a mobile terminal with local area wireless communication between a mobile terminal, an auxiliary terminal, and a participating store's terminal, allowing payment processing without revealing personal information to the store, using a payment processing system that transmits and processes payment information securely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a payer presents a credit card to a participating store for payment, then payment processing is enabled, but personal information is exposed to the store
Solution Approach 1:
The patent introduces a payment gateway server as an intermediary between the payer's terminal and the participating store. The server receives payment information from the terminal, processes it securely without exposing personal details to the store, and returns only payment results. This mediator architecture enables payment processing while preventing personal information leakage to the store.
2Productivity
If credit card information is read by a credit card reader at the participating store, then payment can be made, but credit card information is released to the store
Solution Approach 1:
The patent replaces the traditional mechanical credit card reading system with an electronic information transmission system. Instead of physically swiping or inserting a card at the store's reader, the payer's terminal electronically transmits payment information to the payment gateway server. This substitution eliminates the need for the store to physically handle or read the card, preventing information release while maintaining payment efficiency.
3Device complexity
If personal information is released to participating stores, then payment processing is simplified, but fraudulent use and unwanted solicitations increase
Solution Approach 1:
The patent extracts and separates personal information handling from the payment processing flow. The terminal generates payment information that excludes sensitive personal details, and the payment gateway server processes only this anonymized data. By taking out personal information from the transaction chain, the system simplifies payment processing while eliminating the basis for fraud and unwanted solicitations.

AI summary
Provided are a method and system for payer-centric payment using a mobile terminal through which payment is made while information about a payer is not released to a participating store. Specifically, a terminal of the participating store transmits payment information including a payment amount and participating store identification information to an auxiliary terminal, the auxiliary terminal transmits the payment information to the mobile terminal of the payer, the mobile terminal of the payer transmits the payment information and information about a payment means to pay the payment amount to a payment processing system, and finally, the payment processing system pays the payment amount by using the payment means and then transmits information about a result of payment processing to the mobile terminal of the payer and the terminal of the participating store.
