Solution Overview

Problem

Existing payment methods using payment cards are vulnerable to data theft and fraud, as they require physical card handling and storage of personal information, which can lead to risks of card cloning and unauthorized transactions.

Innovation Solution

A method and system utilizing a mobile device to initiate payments by receiving merchant data, transmitting payment requests to a remote server, verifying customer identity, and implementing transactions between bank accounts, with features such as visual token capture, PIN verification, and encryption of transaction IDs to enhance security and reduce physical handling of sensitive information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a payment card is physically handled and inserted into a card reader, then the payment transaction can be completed, but the risk of data theft and fraud increases

Engineering Contradiction:
Improvetransaction securityVSAvoiddata theft risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the sensitive payment information from the physical payment card and stores it remotely on a server. The mobile device only contains a token or identifier, while the actual card details (card number, expiry date, CVV) are stored securely on the remote server. This extraction eliminates the risk of physical card data theft while maintaining transaction functionality.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a remote server as an intermediary between the mobile device and the payment network. The server acts as a mediator that securely stores payment information, verifies transactions, and communicates with the payment network on behalf of the user. This intermediary layer protects users from directly exposing sensitive card information to merchants or card readers.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If vendors retain card information for repeat orders, then convenience is improved, but the risk of information theft increases

Engineering Contradiction:
Improverepeat order convenienceVSAvoidinformation theft risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent extracts and removes sensitive card information from the vendor's systems. Instead of storing actual card details, the vendor's system only retains a token or reference identifier. When a repeat order is placed, the system retrieves the full card information from the secure remote server using this token, eliminating the need for vendors to store sensitive data locally.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent uses a token or identifier as a copy/reference to the actual card information. This copy allows the system to reference and process payment information without exposing or storing the sensitive original data. The token serves as a safe placeholder that can be stored and transmitted without security risks.

Inventive Principle:
Principle #26Copying

3Reliability

If a mobile device is used to initiate payments remotely, then security is improved, but the device complexity increases

Engineering Contradiction:
Improvepayment securityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent leverages the mobile device's existing universal capabilities (camera, communication interfaces, processing power) to perform payment functions. The same device that users already use for communication and information access is also used for secure payment initiation, eliminating the need for separate dedicated payment hardware and reducing overall system complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The mobile device autonomously performs multiple functions in the payment process: capturing merchant data via camera, communicating with the remote server, verifying transaction details, and initiating payments. This self-service capability eliminates the need for complex intermediary hardware and simplifies the overall system architecture.

Inventive Principle:
Principle #25Self-service
