At many schools, Visitor Management is simply a notebook or sign-in sheet left near a front door. While a system like this will capture visitor data, it makes a number of assumptions that are simply unrealistic in today's world:
- First, a sign-in book assumes a guest is actually going to stop and sign in. If the station is unstaffed, guests may view the process as optional or as an inconvenience and simply walk by.
- Second, a guest can simply write any name in the book, and the discrepancy usually won't be caught until much later.
