Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current methods for disabling payment functions on lost or stolen transaction cards can be intimidating or dangerous for merchants, as fraudsters may pose a threat, and existing systems lack efficient mechanisms to automatically render such cards useless.

Innovation Solution

A computer-implemented method and point-of-sale terminal system that receives payment account data, transmits authorization requests, and upon receiving a status response indicating the card is lost or stolen, activates disabling components to physically or electronically disable the card's payment functionality, such as destroying the magnetic strip or micromodule.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the card issuer transmits a capture request to the merchant, then the transaction card can be disabled, but the merchant faces safety risks and intimidation from fraudsters

Engineering Contradiction:

Improvecard disabling reliabilityVSAvoidmerchant safety risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system enables self-service by allowing the point-of-sale terminal to automatically detect capture status codes and trigger disabling components without requiring manual merchant intervention. The terminal autonomously determines when to disable the card based on authorization response codes, eliminating the need for merchants to manually handle potentially dangerous situations while ensuring reliable card disabling.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The point-of-sale terminal acts as an intermediary between the card issuer and the disabling mechanism. It receives authorization requests, processes response codes, and automatically activates disabling components when capture is indicated. This intermediary role removes the merchant from direct involvement in the disabling process, reducing safety risks while maintaining system reliability.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If manual card capture procedures are used, then merchants can disable lost or stolen cards, but the process is time-consuming and exposes merchants to danger

Engineering Contradiction:

Improvecard disabling effectivenessVSAvoidcard disabling time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary action by pre-configuring the point-of-sale terminal with disabling components and automated detection logic. When a capture status code is received, the terminal immediately activates the disabling mechanism without requiring time-consuming manual procedures. This preliminary setup enables instant card disabling, reducing time loss while maintaining effectiveness.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The automated system performs the disabling action itself based on detected status codes, eliminating the need for merchants to manually execute time-consuming capture procedures. The terminal autonomously determines when disabling is needed and executes it immediately, reducing both time loss and merchant exposure to danger while ensuring reliable card disabling.

Inventive Principle:

Principle #25Self-service

3Ease of operation

If automated disabling components are integrated into the point-of-sale terminal, then card disabling is faster and safer, but the device complexity increases

Engineering Contradiction:

Improvecard disabling easeVSAvoidpoint-of-sale terminal complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system merges the disabling components directly into the existing point-of-sale terminal structure, combining multiple functions (authorization processing, status code detection, and card disabling) into a single integrated device. This merging approach improves ease of operation by automating the process while managing complexity through unified design rather than separate standalone components.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The point-of-sale terminal is designed with multi-functionality, serving both as a transaction processing device and as a card disabling system. By making the terminal universal, the patent avoids adding separate dedicated disabling devices, thereby improving ease of operation while controlling overall system complexity through consolidated functionality.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

The disclosure includes systems and methods for disabling a payment function of a transaction card. The system receives payment account data from a transaction card and transmits a payment authorization request message to a card issuer associated with the transaction card. The system receives, from the card issuer, an authorization request response message. The authorization request response message declines the transaction and includes a status response code corresponding to a status of the transaction card. The system determines whether the status response code indicates that the transaction card is to be captured, and if so, disables the payment function of the transaction card via activation of a disabling system.
