Touchless ATM Transactions via QR Code Optical Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ATMs restrict transactions to a single financial institution, require physical interaction leading to germ transmission and wear, and lack flexibility in dispensing denominations, necessitating multiple visits for specific withdrawals.
Innovation Solution
A system utilizing a mobile device to request transactions through an interbank network, determining compatible ATMs via machine learning, and enabling touchless transactions using QR codes for secure, denomination-specific withdrawals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If ATMs require physical interaction (pressing input keys, touchscreen) to operate, then account holders can initiate transactions, but this creates an environment with the potential to transmit germs, bacteria, viruses, and other pathogens
Solution Approach 1:
The patent replaces the mechanical input system (physical keys, touchscreen) with an optical recognition system. The ATM captures an image of the QR code displayed on the user's mobile device using a camera, and the system processes this visual information to initiate transactions without requiring physical contact between the user and the ATM interface.
Solution Approach 2:
The QR code serves as an intermediary carrier of transaction information. Instead of direct physical interaction or direct data transmission, the transaction details are encoded in the QR code image, which acts as a medium that the ATM camera captures and processes, enabling contactless communication between user and ATM.
2Ease of operation
If ATMs require physical interaction, then transactions can be initiated, but ATMs have a shorter functional service lifespan or require more frequent repairs due to wear caused by use
Solution Approach 1:
The patent eliminates mechanical wear by replacing the physical keypad and touchscreen with a camera-based optical input system. The camera has no moving parts that wear from repeated use, and the image processing occurs electronically, thereby extending the ATM's functional service lifespan while maintaining transaction initiation capability.
3Ease of operation
If ATMs require physical interaction, then transactions can be initiated, but ATMs take time to perform transactions as they must idle until the account holder physically initiates the transaction
Solution Approach 1:
The system allows users to prepare and input transaction details in advance on their mobile devices before arriving at the ATM. The QR code is generated with all transaction information pre-configured, so when the user presents it at the ATM, the transaction can be quickly processed without requiring the user to manually input data at the ATM, thereby reducing idle time and improving productivity.
4Device complexity
If ATMs only offer currency in certain denominations, then the ATM can operate with limited cash handling, but this limits an account holder's ability to withdraw funds in specific denominations
Solution Approach 1:
The system provides feedback to users about ATM cash availability through the mobile device interface. Users can see which denominations are available at selected ATMs before traveling there, and the system can suggest alternative ATMs or denomination combinations that meet the user's needs, thereby maintaining flexibility despite the physical ATM's limited cash handling capabilities.
5Reliability
If account holders must be physically present in front of an ATM throughout the entire transaction process, then security can be maintained, but this is time-consuming for the account holder and inefficient for the ATM
Solution Approach 1:
Users complete all transaction setup, authentication, and confirmation steps in advance on their secure mobile devices before arriving at the ATM. The QR code contains pre-validated transaction information, allowing the ATM to quickly execute the transaction with minimal user presence required, thereby reducing transaction time while maintaining security through the mobile device's authentication mechanisms.

AI summary
Systems and methods are provided for services utilizing transaction devices such as Automated Teller Machines. An example method comprises receiving a request comprising at least one constraint for a transaction and providing at least one ATM that satisfies at least one constraint of the request. A second method comprises analyzing, via a language model, the request, and based on the analysis, determining the at least one ATM that satisfies at least one constraint of the request. A third method comprises utilizing a QR code to perform a transaction at an ATM without receiving tactile input.
