Solution Overview

Problem

Existing payment systems using magnetic cards and RFID devices lack sufficient security, as traditional security measures like PINs and chip technologies are not foolproof against theft and skimming, and existing solutions for improving transaction security have limitations.

Innovation Solution

A payment device and method that uses an enabling card with a processor and coil to simulate a magnetic card swipe by generating a magnetic field based on encrypted information received from a mobile device via Bluetooth, allowing secure transactions without storing sensitive information on the card.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional magnetic stripe cards are used, then compatibility with existing POS terminals is maintained, but security is vulnerable to theft and skimming

Engineering Contradiction:

Improvetransaction securityVSAvoidtheft and skimming vulnerability

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts sensitive card information from the physical card itself and relocates it to a mobile device. The enabling card contains only minimal identification data, while the actual credit card information is stored securely in a mobile application. This extraction eliminates the risk of skimming and theft of card data, as the sensitive information never resides on the enabling card.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a mobile device as an intermediary between the enabling card and the POS terminal. The mobile device holds the encrypted credit card information and communicates with the POS terminal wirelessly. This intermediary layer ensures that the enabling card itself does not contain sensitive data, while still enabling transaction completion through wireless communication.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If PIN codes are required for transactions, then transaction authentication is improved, but PIN disclosure risk increases

Engineering Contradiction:

Improvetransaction authenticationVSAvoidPIN disclosure risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the authentication mechanism from the traditional PIN entry method. Instead of requiring users to manually enter their PIN, the system uses wireless communication to automatically transmit encrypted card information from the mobile device to the POS terminal. This eliminates the PIN entry step and associated disclosure risks while maintaining strong authentication through encrypted data transmission.

Inventive Principle:

Principle #2Taking out (Extraction)

3Reliability

If chip technology (EMV) is implemented, then transaction security is enhanced, but device complexity and cost increase

Engineering Contradiction:

Improvetransaction securityVSAvoidchip embedding and infrastructure requirements

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the complex chip technology requirement from the card system and replaces it with a wireless communication-based solution. Instead of embedding chips in cards and requiring chip readers at POS terminals, the system uses wireless transmission from mobile devices to communicate card information securely. This simplifies the infrastructure while maintaining enhanced security through encryption and wireless authentication.

Inventive Principle:

Principle #2Taking out (Extraction)

4Ease of operation

If RFID devices are used, then contactless payment capability is provided, but security remains vulnerable to theft

Engineering Contradiction:

Improvecontactless payment capabilityVSAvoidsecurity against theft

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent extracts the sensitive payment information from any physical or contactless card and relocates it to a mobile device. The enabling card used in contactless transactions contains only minimal data, while the actual credit card information is stored encrypted in a mobile application. This extraction maintains contactless payment convenience while eliminating the security vulnerabilities associated with RFID card theft.

Inventive Principle:

Principle #2Taking out (Extraction)
