CampusSync - Integrated Campus Dining Ecosystem

A production-ready, campus-scale digital wallet and dining ecosystem for universities.

System Overview

CampusSync enables a unified e-wallet system where:

• Students prepay mess fees into a central wallet
• Only consumed meals are charged (consumption-based billing)
• Skipped meals remain as wallet balance
• Balance can be used across all messes and canteens
• Payments via QR code scanning
• Central accounting and vendor settlement
