Last I checked, Teachers already have a pretty good idea of who hangs out with who. In fact, a very good sense. Why? Teachers are there at lunch. Administrators walk around at lunch. At school events.
The one thing I could think of your point being valid is in possible drug deals, if the school noticed 2 (or more) students going to one remote place every [few] weeks/days. However, I highly doubt they'd be doing real analysis from the data collected.
Also, kids could easily block the RFID's signal with aluminum foil.
