A cinema/entertainment venue locker management system built for multi-branch operations. Admins manage company settings, branches, PC stations, movie schedules, and staff accounts from a central dashboard, while counter operators log in to a dedicated interface to record customer deposits and print thermal receipts instantly. Serial numbers are generated atomically at the database level, so simultaneous prints across multiple PCs and branches never collide. Includes role-based access control, CSRF protection, password hashing, and a searchable receipt history/reporting module.
