Refund by Location

Overview

I developed an innovative blockchain-based system that automates the refund process by leveraging geolocation data. This solution addresses the challenge of verifying customer presence at specific locations before processing refunds, ensuring transparency and reducing fraud in refund transactions.

Key Features

• Geolocation Verification: Utilizes mobile device GPS to confirm customer presence at designated locations
• Smart Contract Automation: Employs blockchain technology to create trustless, automated refund execution based on predefined conditions
• Cross-platform Mobile Interface: Built with Flutter to provide a seamless user experience across iOS and Android devices
• Secure Transaction Processing: Implements cryptographic verification to ensure data integrity and prevent location spoofing
• Real-time Status Updates: Provides instant feedback on refund eligibility and processing status

Technical Implementation

• Frontend: Flutter/Dart for a responsive and intuitive mobile application interface
• Blockchain Integration: Smart contracts written in Solidity for transparent, immutable transaction records
• Security: Implements multi-layer verification to prevent GPS spoofing and fraudulent claims
• Scalability: Designed with optimized contract architecture to minimize gas costs and support high transaction volumes
• Location Services: Integrates with device GPS and mapping APIs for precise location validation

Current Usage

The system is applicable in various scenarios where location-based verification is critical, such as event ticket refunds, service guarantees, and promotional offers. It helps businesses implement location-contingent policies while providing customers with a transparent and efficient refund process.

Business Impact

This solution significantly reduces manual processing costs and fraud-related losses for businesses offering location-based services or guarantees. It increases customer trust through transparent verification processes and immediate refund execution when conditions are met. The technology has particular relevance in the events industry, travel and tourism, and retail sectors where physical presence verification is essential for policy enforcement.
