Autonomous bill splitting by indicating who order what

FairShare Project

Inspiration

Our inspiration came from a common everyday problem: splitting the bill when dining out with friends. We've all experienced the awkwardness and complexity of dividing expenses fairly. As computer science students, we saw an opportunity to leverage technology to solve this financial friction point while contributing something valuable to the financial sector.

What it does

FairShare transforms group expenses with AI-powered receipt scanning and intelligent bill splitting. Users simply snap a photo of their receipt, and our app automatically identifies items, calculates fair splits, and facilitates seamless payments between friends. It's designed to be a comprehensive financial tool that makes expense sharing effortless, accurate, and transparent.

How we built it

We built FairShare using React Native for cross-platform mobile development, integrated with OpenAI's Vision API for receipt processing. Our backend services are implemented with Express.js, while Firebase handles user authentication and data storage. We started with ideation on Saturday morning and continuously refined our UI/UX while implementing core functionality through an iterative development process.

Challenges we ran into

Learning React Native as first-time mobile developers
Integrating AI-based receipt parsing with acceptable accuracy
Connecting various components from different team members
Managing Git branches and resolving merge conflicts
Balancing development time with other hackathon events
Configuring packages and dependencies in a mobile environment

Accomplishments that we're proud of

We successfully built a functional mobile application in just 20 hours, despite none of our team members having prior React Native experience. We're particularly proud of implementing an AI-powered receipt scanning system that accurately detects items and facilitates fair splitting, all while creating an intuitive user interface that makes complicated financial interactions simple.

What we learned

This project provided invaluable experience with React Native, AI integration, and mobile app development workflows. We learned how to effectively collaborate under tight deadlines, partition work appropriately, and integrate diverse components into a cohesive application. The challenges we faced taught us to quickly adapt and find creative solutions to technical problems.

What's next for FairShare

We plan to implement secure transaction features like rotating QR codes, similar to Google Authenticator, for payment verification. Long-term, we're exploring advanced concepts like:
