Paging boards are communication tools used to display messages or announcements in high-traffic areas, such as airports, train stations, or hospitals. They can be electronic or manual and often use scrolling text, flashing lights, or a combination of visual and auditory cues to attract attention and convey information. Electronic paging boards may feature LED or LCD displays and can be easily updated to show real-time data, such as flight statuses or waiting times. Manual paging boards might use letter boards or flip cards to display messages that are updated periodically. Paging boards play a critical role in keeping people informed and ensuring smooth operations in busy environments.
