Student Attendance

Hello
I hope everyone is doing well, I have an issue while displaying the Currently Available Student in the Lab.

I want to Create a Dashboard of total students in a Lab with their "Name", "Total Time in Lab" and their "Arrival/Check-in Time" after they Check In. Once a student checks out, their information will drop out from the Dashboard.

Check the "Dasboard" sheet for and example of what a Dashboard would look like at two intervals: 1) 04:26 PM, and 2) 05:00 PM

Students will use RFID to check in. Ideally, I would prefer to have a message box or window of the Dashboard I described. This Dashboard will eventually get displayed On TV from a Computer in Lab for students to know for the time they have spent in Lab.
