Solution Overview

Problem

Traditional ATMs require physical payment cards for transactions, leading to theft and skimming risks, while cardless systems lack user control over transaction details.

Innovation Solution

A cardless ATM system using a mobile device to input transaction details and receive a unique identifier from the ATM, which is authenticated and transmitted to a processing server to release transaction account details securely, allowing transactions without a physical card.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a physical payment card is used for ATM transactions, then traditional transaction processing is enabled, but the risk of theft and skimming increases

Engineering Contradiction:

Improvetransaction securityVSAvoidtheft and skimming risks

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the physical payment card with a virtual card represented as a graphic on a mobile device display. The virtual card contains encoded account information that can be transmitted wirelessly to the ATM, eliminating the need for physical card handling while maintaining transaction functionality and security.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent replaces the mechanical insertion of a physical card into the ATM with a wireless communication process. The mobile device transmits card information electronically to the ATM via wireless signals, eliminating the mechanical card insertion step and associated skimming risks.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If mobile device with near field communication is used for cardless transactions, then physical card theft is reduced, but the device complexity and cost increase

Engineering Contradiction:

Improveprotection against physical card theftVSAvoidmobile device requirements

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent enables any mobile device with a display and wireless capability to function as a payment card, regardless of whether it has specialized near field communication hardware. The system works with standard mobile devices, eliminating the need for expensive specialized components while maintaining cardless transaction capability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If cardless ATM system is implemented, then physical card presentation is eliminated, but user control over transaction details is reduced

Engineering Contradiction:

Improveelimination of physical card handlingVSAvoiduser control over transactions

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent requires the user to manually input transaction details (amount, account selection) into the mobile device before initiating the transaction. This preliminary input ensures the user has full control over transaction parameters, and the system only transmits the information the user has explicitly provided after authentication.

Inventive Principle:

Principle #10Preliminary action

AI summary

A method for initiating a cardless automated teller machine (ATM) transaction via a mobile computing device includes: storing, in a memory of a mobile computing device, at least transaction account data and authentication data; receiving, by an input device of the mobile computing device, at least desired transaction data and authentication information; receiving, by the input device of the mobile computing device, a unique identifier associated with an automated teller machine (ATM); authenticating, by an authentication module of the mobile computing device, the received authentication information based on the stored authentication data; and electronically transmitting, by a transmitting device of the mobile computing device, at least the received desired data and unique identifier and a result of the authentication to an external computing system.
