The Online Bus Pass System provides a digital platform for students and regular passengers to apply for, manage, and renew bus passes. The system involves three primary users: Passengers, Employees, and Administrators. Administrators have complete control over the system. All user details, bus pass records, payment transactions, route information, and system logs are securely stored in the database.
Online Bus Pass System Design Flow Summary:
Passenger submits registration/application details → System processes request → Payment is completed through Payment Gateway → Employee verifies application → System generates bus pass → Passenger downloads the approved pass → Administrator monitors and manages the entire process.
