Mobile-Auth Cash Dispensing Terminal With Remote Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ATM systems require users to insert a card and enter a PIN, which can be inconvenient and may not provide the best exchange rates for foreign travelers, necessitating improved methods for banking transactions.
Innovation Solution
A cash-dispensing banking terminal that uses a mobile device to authenticate and authorize transactions remotely, allowing for cash withdrawals without a keypad, card reader, or extensive user interface, utilizing NFC and QR codes to validate transactions pre-created on a mobile device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional ATM systems use card readers and keypads for authentication, then security is maintained through physical card presence and PIN entry, but user convenience is reduced and the system complexity increases
Solution Approach 1:
The patent extracts the authentication function from the physical ATM terminal and relocates it to the user's mobile device. The mobile device stores cryptographic credentials and performs authentication locally, then communicates only a verification token to the ATM. This removes the need for card readers, keypads, and complex input interfaces at the ATM terminal.
Solution Approach 2:
The patent introduces a cryptographic intermediary system consisting of mobile device software and backend servers. This intermediary handles the complex authentication logic, credential verification, and transaction authorization, allowing the ATM terminal itself to remain simple while maintaining strong security through remote verification.
2Productivity
If ATMs require physical card insertion and PIN entry, then authentication security is maintained, but transaction speed and efficiency are reduced
Solution Approach 1:
The patent implements preliminary authentication actions where the user's mobile device stores cryptographic credentials and pre-establishes trust relationships with the banking system. Before visiting the ATM, the user has already completed account linking and authentication setup in the mobile app, enabling rapid verification at the terminal without manual card insertion or PIN entry.
Solution Approach 2:
The patent replaces mechanical authentication methods (card swiping, magnetic stripe reading, physical keypad entry) with electronic cryptographic verification. The mobile device uses secure element hardware and cryptographic protocols to authenticate the user, then communicates verification tokens to the ATM via NFC or other wireless interfaces, eliminating mechanical wear and human error.
3Adaptability or versatility
If traditional ATMs use extensive user interfaces with multiple buttons and displays, then user input flexibility is maintained, but the device complexity and maintenance requirements increase
Solution Approach 1:
The patent makes the user's mobile device the universal interface for all banking transactions. The mobile app provides all necessary input capabilities (account selection, transaction type, amount entry) and displays transaction information, making the ATM terminal itself a simple cash dispensing device with minimal interface requirements. This multi-functional approach consolidates interface complexity into the user's existing device.
4Reliability
If ATMs provide cash dispensing with traditional authentication methods, then service reliability is maintained, but exchange rate competitiveness for foreign travelers is reduced
Solution Approach 1:
The patent enables dynamic transaction processing where the system can adapt to different user needs and locations. The mobile-based system allows users to initiate transactions remotely, check real-time exchange rates, and receive notifications when optimal rates are available. This dynamic approach enables the bank to offer competitive exchange rates to foreign travelers by providing real-time market data and flexible transaction timing.

Function Achieved in This Case
Enables secure, efficient, and convenient cash withdrawals by validating transactions remotely, reducing the need for physical card presence and providing improved exchange rates through mobile authentication.
Implementation Method 1
The receiver may receive the banking transaction request using wireless near field communication (NFC) traveling a distance of three feet or less and the transmitter may be an NFC wireless transmitter.

AI summary
A cash-dispensing banking terminal has a housing, a transmitter, a receiver, a cash dispenser, and a processor to control the cash dispenser. A pre-created transaction request was earlier created with a mobile device before a banking customer and the mobile device arrive at the cash-dispensing banking terminal. A remote computing device authenticates and authorizes the transaction request before the customer and the mobile device arrive at the cash-dispensing banking terminal. When the transaction is authenticated and authorized, a remote computer generates an executable transaction request and generates and sends a transaction identifier associated with an executable transaction request to the mobile device. The receiver receives the transaction identifier from the mobile device, when the customer is at the banking terminal. The remote computer and/or other devices verify the transaction identifier is valid. The banking terminal performs the transaction request while the customer is at the banking terminal.
