ArcPay — Reach Out and Pay

Inspiration

We asked ourselves: What if paying was as effortless as Tony Stark firing a repulsor beam?
While the world still fumbles with cards, cash, and clunky mobile apps, we imagined a system where your palm becomes your passport to seamless transactions.

ArcPay was inspired by:

Iron Man’s sleek tech integration
Wakandan biometric precision
The need for contactless, wallet-free payments

Enter ArcPay — making “reach out and pay” the new global standard.

What It Does

ArcPay redefines the payment experience:

✅ Palm Authentication — Your unique palmprint becomes your payment ID
✅ Instant Transactions — Just scan and go
✅ Military-Grade Security — CNN-powered verification with 98.7% accuracy
✅ Full Payment Ecosystem — From user wallets to merchant dashboards

“No cards. No phones. Just you.”

How We Built It

🧠 The Arc Reactor Core (Backend)

Flask — High-performance Python server powering payments
TensorFlow/Keras — Custom CNN trained on 10,000+ palm images
MongoDB Atlas — Lightning-fast vector similarity search for palm matching

🖥️ The HUD Interface (Frontend)

React + Vite — Modern, responsive UI
Framer Motion — Smooth, futuristic transitions
Expo Camera — Precision palm scanning through mobile

🤖 Machine Learning Pipeline

Image Preprocessing — OpenCV-based alignment & enhancement
Feature Extraction — CNN with triplet loss for robust feature learning
Matching Engine — Cosine similarity-based palmprint matching in MongoDB

🔥 Challenges We Overcame
