Cardless ATM Withdrawal via QR Code Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ATM systems require a payment card for fund withdrawals, limiting access for individuals without a card, particularly in situations like natural disasters where infrastructure for card distribution is lacking.
Innovation Solution
A method and system for cardless withdrawal from ATMs, involving user input of a unique code, device identifier, and transaction amount, which are transmitted electronically to authenticate and authorize the withdrawal, allowing dispensing of funds without a card.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a payment card is required for ATM withdrawals, then transaction security is maintained, but accessibility for individuals without cards is limited
Solution Approach 1:
The patent uses a QR code (visual copy) that contains encoded account information, replacing the physical payment card. The QR code serves as a digital representation of the card data, allowing the ATM to read and process withdrawal requests without requiring the actual card presentment
Solution Approach 2:
The patent replaces the mechanical card insertion process with an optical scanning system. The ATM uses a camera or scanner to capture the QR code image and extract data optically, eliminating the need for physical card slots, magnetic stripe readers, or chip readers
2Productivity
If payment cards are distributed to recipients, then fund access is enabled, but infrastructure requirements and distribution time increase
Solution Approach 1:
Instead of producing and distributing physical cards through complex supply chains, the system generates digital QR codes that can be instantly delivered via mobile devices. This eliminates card printing, shipping, and physical distribution infrastructure while maintaining secure access credentials
Solution Approach 2:
The system pre-generates QR codes containing all necessary account information before the user needs to access funds. These codes can be distributed in advance through any digital channel (SMS, email, mobile app), allowing immediate ATM access without waiting for physical card delivery

AI summary
A method for cardless withdrawal from an automated teller machine includes: receiving, by an input device of an automated teller machine (ATM), user input comprising at least: a first code, a device identifier associated with a computing device, and a transaction amount; electronically transmitting, by the ATM, at least the first code, device identifier, and the transaction amount to a first computing system; receiving, by a receiving device of the ATM, a transaction account number from the first computing system; electronically transmitting, by the ATM, a withdrawal request including at least the transaction account number and the transaction amount to an acquiring institution; receiving, by the receiving device of the ATM, an indication from the acquiring institution that indicates approval of the withdrawal request; and dispensing, by a dispensing module of the ATM, one or more payment instruments having a value equivalent to the transaction amount.
