The screen will update itself in real-time, so that as employees punch in you will see them appear on the screen. When they punch out, you will see them disappear from the screen. After they have punched out, or switched out of an active time segment, you can view the completed time sheet on the View Time Sheets screen.
To see the GPS Location of a specific employee, just click on the employee in the list. The GPS marker for that employee will then be highlighted and you will see a bubble with the details of the recent in-punch.
This is a helpful screen when you want to see who is clocked in currently. Many companies find value in leaving this screen open on a computer while they work on other things. By doing so, they have a constantly updated list on their screen with notifications as workers clock in for work.
