The difference between signboards and wayfinding

Quick answer：

Signboards are typically used to identify or indicate a specific location, such as a store or building. Wayfinding, on the other hand, is a system used to guide people through a complex environment, such as a city or a large building. While signboards can be part of a wayfinding system, they focus more on the identification of specific places, while wayfinding systems provide a broader navigation context.
