Like most organizations you are obligated to know who is on site so you can account for them in an emergency. You may also want to know if a person comes into your building after normal business hours, or if they are on site alone, or if they are expected to depart at 9pm but did not, or how many people are onsite after 6pm and much more...
One of the benefits of WhosOnLocation is the way you can set up various business rules to automate notifications and alerts and make sure that nothing falls through the cracks. Triggers is the tool that you use to make all of this automation happen.
With Triggers, you can send notifications to anyone inside or outside of the organization, deny access to people who do not meet requirements, and give handy notices or messages with pop-ups.
