A few times now I've gotten a citation because I didn't notice that the person was the wrong height. How can I tell whether someone is a different height than their information claims?
You can highlight their height information and then their face in inspect mode. This will allow you to detain or reject anyone with fake ID or falsified information.
You can visually check it for yourself by looking at the height markings behind the people, but most people move around and bop up and down, so it can be difficult to tell visually if they are "close" to their reported height.
