The queuing system is primarily composed of vehicle queuing and number calling systems, vehicle registration and reservation clients, WeChat official account, cloud database, and LED display screens.

The vehicle queuing system quickly registers incoming vehicles, sequentially calling vehicles in line, allowing drivers to check queuing information at any time. It comes with display devices (optional between LED and LCD screens). Whales Technology's vehicle queuing system enhances user-friendliness by re-calling vehicles that haven't arrived and allows for specific vehicle calling or real-time queuing adjustments. It can also voice-announce license plate numbers and queuing numbers. The system pre-records information for electronic automatic billing, and can be authorized and charged on a monthly basis.
