Smart signage refers to digital displays that use technology to convey information in real-time. These signs can show various content, such as advertisements, announcements, or wayfinding information, and can be updated remotely. They often utilize LED or LCD screens and can be found in places like shopping malls, airports, and public transportation systems. The key feature of smart signage is its ability to interact with users and adapt to their needs. For example, some systems can display targeted messages based on the time of day or audience demographics. Additionally, smart signage can integrate with other technologies, such as sensors and mobile apps, to enhance user experience.
