UOG Fee Token System is an OCI-based use case diagram modeling student fee token lifecycle management across three actor roles: students, administrators, and finance officers. The system orchestrates authentication via SSO Service, token generation and management, payment processing with verification workflows, and comprehensive audit logging with multi-channel notifications. This architecture demonstrates role-based access control, secure payment handling with KMS encryption, and compliance-ready audit trails essential for educational institutions managing fee collection at scale.
