I'm looking for an app that will allow me to track my employees to see if they are in the building or not without having to search for them. For instance, when they sit down at their computer, they press a button on their computer and the president of the company is able to see if that person is signed in or not. Most people leave their computers on at night, so just looking at the network won't suffice. So, if they go to lunch, they click the "out" button and when they come back, they click the "in" button. Does anyone have any suggestions? It can be web based also. Any help would be appreciated.
