Cardless Cash Withdrawal Location Check Against QR Code Fraud

The system provides real-time feedback to the user by displaying the ATM location derived from the QR code and comparing it with the user's current location. This feedback loop allows users to verify whether they are at the correct ATM before completing the transaction, enabling them to detect and avoid fraudulent situations where QR codes may be manipulated or misplaced.

The patent introduces an intermediary verification step between the QR code scanning and the cash dispensing process. The system acts as a mediator by independently determining the ATM location from the QR code data, comparing it with the user's location, and only allowing the transaction to proceed if the locations match. This intermediary check prevents direct execution of potentially fraudulent transactions.

The location verification is performed preliminarily and automatically in the background before the user completes the transaction. The system determines the ATM location from the QR code, compares it with the user's current location, and prepares the verification result in advance. This preliminary action ensures that the security check is completed before the critical transaction moment, minimizing additional time required from the user.

The system performs the location verification process autonomously without requiring active user participation. The electronic device automatically retrieves location data, compares it with the ATM location, and presents the verification result to the user. This self-service approach minimizes the time burden on users while maintaining security, as the complex verification steps are handled automatically by the system.

The patent leverages existing multi-functional components in modern electronic devices to implement location verification without adding significant complexity. The device uses its existing camera to scan the QR code, its existing GPS or location services to determine current location, and its existing processor to compare the two locations. By making these existing components serve the additional function of fraud detection, the system avoids the need for dedicated specialized hardware, thereby limiting the increase in device complexity.

The location verification process merges multiple functions into a unified workflow: the QR code scanning function, the location determination function, and the fraud detection function are combined into a single integrated process. The system simultaneously processes the QR code data and location data, compares them, and generates a verification result, rather than treating these as separate sequential steps. This merging reduces the overall system complexity by eliminating redundant components and streamlining the verification architecture.
