Dynamic ATM Transaction Limits via Mobile Device Location Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current financial transaction systems face challenges in balancing fraud prevention with customer convenience, particularly at ATMs, where transaction limits can hinder users from accessing their funds beyond daily withdrawal limits without verifying the user's location.
Innovation Solution
A computer-based system dynamically adjusts transaction limits for financial accounts by verifying the location of a customer's mobile device associated with the account, allowing temporary increases or decreases based on active or passive location responses and risk scores, enabling transactions beyond daily limits if the device is proximate to the ATM.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transaction limits are imposed on financial transactions at ATMs, then fraud risk is reduced, but customer convenience deteriorates
Solution Approach 1:
The patent implements dynamic transaction limits that adjust in real-time based on location verification. The system transitions from static predetermined limits to dynamic limits that are temporarily increased when the customer's mobile device is verified to be near the ATM, thereby resolving the contradiction between fraud prevention and customer convenience
Solution Approach 2:
The patent introduces location verification of mobile devices as an intermediary mechanism between the customer and the transaction limit enforcement. This intermediary provides additional security verification while enabling convenient temporary limit increases, addressing both fraud prevention and customer convenience requirements
2Ease of operation
If transaction limits are increased to allow larger withdrawals, then customer convenience is improved, but fraud risk increases
Solution Approach 1:
The system dynamically adjusts transaction limits based on real-time location verification rather than using fixed high limits. This allows the system to permit higher limits only when needed (when customer is verified present at ATM) while maintaining low limits otherwise, thus improving convenience without permanently increasing fraud risk
Solution Approach 2:
The patent changes the transaction limit parameter dynamically based on location verification status. The limit transitions from a static low value to a temporarily elevated value only when the customer's mobile device is verified to be in proximity to the ATM, balancing convenience and fraud prevention
3Reliability
If location verification is implemented to dynamically adjust limits, then fraud prevention is enhanced, but system complexity increases
Solution Approach 1:
The patent leverages the mobile device's existing GPS/location capabilities for authentication purposes. By reusing the mobile device's built-in location functionality rather than introducing new hardware, the system enhances fraud prevention while minimizing the increase in overall system complexity
Solution Approach 2:
The system uses the customer's own mobile device to provide location verification information. The mobile device autonomously provides its location data through GPS or other location services, eliminating the need for additional verification hardware or complex manual verification processes

AI summary
An example method includes receiving information related to a transaction with a financial account initiated by a customer at a financial terminal, the financial account including a transaction limit. Based on the information related to the transaction exceeding the transaction limit for the financial account, the method includes identifying a mobile device associated with the financial account and receiving location information of the mobile device via one or both of a passive location response or an active location response. Based on the location information of the mobile device, the method includes determining that the mobile device is located within a predetermined distance from a location of the financial terminal and temporarily changing the transaction limit for the financial account by a variable amount based on whether the location information of the mobile device was received via the one or both of the passive or the active location response.
