I work in a tertiary institution and there have been a lot of discussions about implementing IDs with those chips. They have met with fierce resistance, surprisingly from many lecturers. The main idea behind the usage of IDs with RFID chips is to monitor "hot zones" on campus and with a view to better allocate funds and resources. So if many students use a particular building but it doesn't have lots of facilities such as car parks, wifi hotspots, etc., then they can use the data to support upgrading those facilities.
Several lecturers deemed it the most gross invasion of their privacy since they do not at all support the idea of being tracked as they move around campus. I have no real issue with it, because if you are where you're supposed to be, you have no worries. Regarding the original student, before you begin a school, you are issued with the rules. The ID wasn't a sudden thing, and if she and her family didn't want or support the idea of it, why did they bother enrolling her there in the first place?
