Cardless ATM Authentication via Mobile Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ATM systems rely on traditional card-based authentication methods, which can be inconvenient and less secure compared to modern mobile device security features.
Innovation Solution
Implementing a cardless authentication method that uses a mobile device to authenticate users at an ATM, leveraging authentication information such as passwords, biometric data, or QR codes generated by the mobile device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional card-based authentication is used at ATM, then the system is simple to operate, but security is compromised and transaction limits are restricted
Solution Approach 1:
The patent introduces a mobile device as an intermediary between the user and the ATM system. The mobile device generates authentication information (such as dynamic codes or biometric data) that serves as a mediator to prove user identity without requiring physical card insertion. This intermediary approach enhances security while maintaining user convenience.
Solution Approach 2:
The patent replaces the mechanical card insertion process with an electronic/digital authentication method. Instead of physically inserting a card into the ATM, users authenticate through their mobile devices using electronic credentials, biometric scanners, or generated codes. This substitution eliminates the need for physical cards while improving security and convenience.
2Adaptability or versatility
If card-based authentication is used, then the system architecture is simple, but service options and transaction limits are restricted
Solution Approach 1:
The patent implements a universal authentication framework where the mobile device can serve multiple authentication purposes (generating codes, biometric verification, location-based authentication). This multi-functional approach allows the system to support diverse service options and transaction types without requiring separate authentication mechanisms for each service.
Solution Approach 2:
The patent adds a new dimension to authentication by incorporating mobile device capabilities (such as GPS location, device identifiers, biometric sensors) that exist outside the traditional ATM card paradigm. This dimensional expansion enables enhanced service options and higher transaction limits by leveraging additional authentication vectors beyond simple card presence.

AI summary
Systems and methods for cardless authentication of a user at an automated teller machine are described. A method includes detecting, by a mobile device of a customer, a proximity notification including an identifier broadcast from an automated teller machine within a designated time range, the automated teller machine having a transaction card withdrawal limit; transmitting the identifier, a customer token, and a device token to a bank computer system; transmitting a signal to the automated teller machine to initiate the pre-staged cash withdrawal; and providing authentication information to the automated teller machine for authentication to enable the user to perform the pre-staged cash withdrawal at the automated teller machine with an increased cash withdrawal limit, where the increased cash withdrawal limit is higher than the transaction card withdrawal limit and the transaction amount exceeds the transaction card withdrawal limit.
