Our Access Control System (ACS) is developed as a standalone system which can operates separately or to be part of the complete eco-system to be integrated with the ticketing system. One of the business requirement was to standardize our user interface using the same design framework as the ticketing system for maintainability and scalability. Our complex rule engine is designed to handle rules for different types of events, especially for theme parks with complex requirements & usage, while also allowing for flexibility to extend in future requirements.
