Cardless Cash Withdrawal Authentication for Cross-Bank ATM Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cash withdrawal systems at ATMs limit users to their own bank's ATMs and increase fraud vulnerabilities when using cardless transactions.
Innovation Solution
An interoperable system that generates an authentication code on a user's device, validates the withdrawal request, identifies the issuer system, and authorizes fund dispensing at any ATM or merchant point-of-sale without a physical payment device, enabling transactions across different banks and countries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cardless cash withdrawal is enabled at proprietary ATMs, then ease of operation is improved, but vulnerability to fraud increases
Solution Approach 1:
The system generates an authentication code in advance that is displayed on the user's mobile device. This code serves as preliminary verification before the actual withdrawal transaction occurs at the ATM, ensuring that only authorized users can initiate cardless withdrawals while maintaining ease of operation
Solution Approach 2:
The authentication code acts as an intermediary element between the user's mobile device and the ATM transaction. The code is transmitted from the mobile device to the ATM to verify the user's identity, providing a secure bridge that enables cardless withdrawal while preventing fraud
2Adaptability or versatility
If cross-bank ATM interoperability is implemented, then adaptability is improved, but system complexity increases
Solution Approach 1:
The authentication code system is designed to be universally applicable across multiple banks and ATM networks. The same code generation and verification mechanism works regardless of which bank's ATM is used, enabling cross-bank interoperability without requiring bank-specific implementations that would increase system complexity
Solution Approach 2:
The system uses the user's existing mobile device as a copy of their payment credentials. Instead of requiring physical cards or bank-specific interfaces, the mobile device replicates authentication functionality across different banks, simplifying the interoperability architecture while enhancing adaptability

AI summary
A method for dispensing funds including receiving a withdrawal initiation request generated by a user device of a user, generating an authentication code associated with the withdrawal initiation request, receiving a withdrawal completion request from at least one of an automated teller machine (ATM) and/or a merchant point-of-sale (POS) device, validating the withdrawal completion, identifying an issuer system associated with the withdrawal completion request, generating an authorization request, transmitting the authorization request to the issuer system, receiving an authorization response, and transmitting a cash dispense message to cause the at least one of the ATM and/or the merchant POS device to dispense the withdrawal amount. Systems and computer program products for dispensing funds are also disclosed.
