Solution Overview

Problem

Existing systems rely on user identification of virtual transaction numbers, leading to potential transaction failures, improper transactions, and security risks due to incorrect identification.

Innovation Solution

A method and device that determine the location of a projectable transaction card and match it with a merchant location, automatically identifying and displaying a unique virtual transaction number associated with the merchant for secure and accurate transactions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If user identification of virtual transaction numbers is used, then the system is simple to operate, but transaction reliability deteriorates due to potential incorrect identification

Engineering Contradiction:

Improveuser identification processVSAvoidtransaction accuracy

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system performs automatic merchant identification and virtual transaction number selection based on location data, eliminating the need for user intervention. The device autonomously determines the merchant, retrieves the associated virtual transaction number, and displays it for use, allowing the system to serve itself rather than relying on user identification

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The manual user identification process is replaced with an automated electronic system that uses location-based data matching. The device automatically compares current location with stored merchant location data to identify the merchant and retrieve the corresponding virtual transaction number, substituting mechanical user action with electronic automation

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If automatic location-based identification is implemented, then transaction reliability improves, but device complexity increases

Engineering Contradiction:

Improvetransaction accuracyVSAvoidsystem architecture

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The projectable transaction card serves multiple functions: it acts as a payment instrument, a location tracking device, and an automatic virtual transaction number dispenser. By integrating these functions into a single device, the system achieves reliable automated identification without requiring multiple separate complex systems

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

Merchant location data and virtual transaction number associations are pre-stored in the device's database before actual use. When the card is presented at a merchant location, the system simply needs to match the current location with pre-stored data, eliminating the need for complex real-time computation or external database queries during the transaction

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If virtual transaction numbers are displayed continuously, then ease of operation is maintained, but security deteriorates due to potential exposure

Engineering Contradiction:

Improveaccessibility of transaction numberVSAvoidsecurity risk

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The display of the virtual transaction number is made dynamic rather than static. The number is projected only when needed at the merchant location and automatically removed afterward. This dynamic display behavior maintains ease of operation during transactions while minimizing security risks by limiting exposure time and context

Inventive Principle:

Principle #15Dynamics

AI summary

A device may determine information that identifies a location of a projectable transaction card that is capable of being used to conduct a transaction associated with a merchant. The device may determine that the location of the projectable transaction card matches a location associated with the merchant. The device may identify a virtual transaction number that is unique to the merchant, previously associated with the merchant, unique to an account associated with the projectable transaction card, and to be used in conducting the transaction. The device may provide the virtual transaction number for display on a display screen of the projectable transaction card. The virtual transaction number may not be displayed on the display screen of the projectable transaction card prior to a determination that the location of the projectable transaction card matches the location associated with the merchant.
