Solution Overview

Problem

The existing card payment method is prone to illegal use, leakage of personal information, difficulty in identifying the real cardholder, and separate management of online and offline payments, reward points, and discounts, leading to inconvenience for users.

Innovation Solution

A method and system that integrates online and offline payment systems by transmitting order information from a POS terminal to a user's electronic device, determining the best payment method based on discount and reward benefits, and requesting payment approval, allowing for secure and convenient payment without a magnetic credit card.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If card payment method is used, then payment can be made at POS terminal, but risk of illegal use and personal information leakage increases

Engineering Contradiction:

Improvepayment securityVSAvoidillegal use risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent creates a virtual copy of the card payment system through a mobile terminal application. Instead of using a physical magnetic stripe card that can be cloned, the system generates a virtual card representation in the mobile device that communicates with the POS terminal via NFC or other wireless technologies. This virtual copy eliminates the risk of magnetic stripe cloning while maintaining payment functionality.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The mobile terminal acts as an intermediary between the user's card information and the POS terminal. Rather than directly exposing the magnetic stripe data or requiring manual signature verification, the mobile device serves as a secure intermediary that transmits authenticated payment information to the terminal, reducing direct exposure of sensitive data.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If signature verification is used for cardholder identification, then authentication can be performed, but identification accuracy decreases due to easy forgery

Engineering Contradiction:

Improveauthentication processVSAvoidcardholder identification accuracy

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The patent replaces the mechanical signature verification process with electronic authentication methods. Instead of manually comparing signature patterns on paper, the system uses digital authentication mechanisms including biometric verification (fingerprint, facial recognition), PIN codes, or cryptographic authentication through the mobile terminal, which cannot be forged like handwritten signatures.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of manufacture

If online and offline payment systems are managed separately, then each system can be processed independently, but user convenience decreases due to multiple cards needed

Engineering Contradiction:

Improvesystem processing independenceVSAvoiduser convenience

Core Design Contradiction:

Ease of manufactureVSEase of operation

Solution Approach 1:

The patent merges online and offline payment capabilities into a single mobile terminal application. The mobile device stores multiple payment methods and card types (credit cards, debit cards, reward cards, membership cards) and can automatically select and present the appropriate card for the transaction type, eliminating the need for users to physically switch between multiple cards for different payment systems.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The mobile terminal application provides universal payment functionality that works across both online and offline channels. A single application serves multiple purposes: storing various card types, selecting appropriate payment methods based on transaction context, communicating with POS terminals via NFC, and interfacing with online payment systems, making the device a multi-functional payment solution.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Adaptability or versatility

If multiple cards (credit card, reward card, membership card) are required for payment, then various benefits can be accessed, but operation complexity increases

Engineering Contradiction:

Improvebenefit access capabilityVSAvoidnumber of cards to manage

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the payment information storage and management within the mobile terminal application. Different card types (credit cards, reward cards, membership cards) are stored as separate digital records with distinct properties and benefits. The application automatically segments the selection process by evaluating transaction context and card compatibility, presenting only relevant payment options to the user rather than requiring manual selection from all available cards.

Inventive Principle:

Principle #1Segmentation
