If you’re list most schools, you not only work with currently enrolled students but you also serve people from your community that are not enrolled or are prospective students. This means that they either don’t have Student ID number or they don’t remember it.
When a student signs into your lobby, how do you know he is who he says he is? How do you know he’s not posing as someone else? Don’t you wish there was a way to see a picture of the student who has signed in?
