Solution Overview

Problem

Consumers face limitations in conducting transactions at Automated Teller Machines (ATMs) without traditional plastic payment cards, seeking a method to interact with ATMs using mobile devices for cash withdrawals and other transactions.

Innovation Solution

Systems and methods enable mobile devices to initiate ATM transactions by capturing an ATM code, which is used to authenticate and facilitate transactions with the ATM, allowing users to perform various transactions without inserting a physical card, utilizing wireless communication techniques and dynamic or static ATM codes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional plastic cards are used for ATM transactions, then the transaction process is simple and secure, but consumers are limited in conducting transactions without physical cards

Engineering Contradiction:

Improvetransaction method flexibilityVSAvoidoperation simplicity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent creates a digital copy of the card account information stored in the mobile device's secure element, allowing the mobile device to function as a virtual replacement for the physical card. The近场通信模块 uses this digital copy to authenticate with the ATM, eliminating the need for physical card insertion while maintaining transaction security and simplicity

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent replaces the mechanical card insertion process with wireless近场通信. Instead of physically inserting a plastic card into the ATM's card reader, the mobile device uses electromagnetic fields to transmit authentication data, substituting a mechanical interaction with an electronic one while achieving the same transaction outcome

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If mobile devices are used to initiate ATM transactions, then cardless transactions are enabled, but the system complexity increases

Engineering Contradiction:

Improvetransaction method flexibilityVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a transaction management system as an intermediary between the mobile device and the ATM. This mediator handles the complex authentication protocols, secures the communication channels, and coordinates the transaction flow, allowing the mobile device and ATM to interact without either needing to understand the full complexity of the transaction process

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent divides the transaction system into distinct functional modules: the mobile device with its secure element and近场通信模块, the ATM with its card reader and display, and the transaction management system. Each segment handles specific tasks independently, reducing the complexity burden on any single component while enabling cardless transactions

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If physical cards are required for ATM transactions, then authentication is straightforward, but consumers must carry multiple cards for different accounts

Engineering Contradiction:

Improveaccount access flexibilityVSAvoidnumber of cards to carry

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent makes the mobile device a universal access tool by storing multiple account credentials in its secure element. A single mobile device can authenticate with ATMs for multiple different bank accounts, replacing the need to carry separate physical cards for each account while maintaining straightforward authentication through the近场通信 interface

Inventive Principle:

Principle #6Universality (Multi-functionality)
