My problem is all the school administrators talking about how this improves campus safety. Even though it can only track tagged kids. The guy with high powered rifle walking onto the campus cant be sensed or tracked by the system.
The other thing is these are active battery powered tags, which are very expensive. Why cant they just have standard cards with passive rfid chips, like a lot of us use for mass transit. Then instead of a tracking system switch all the doors in the school to remain locked at all times and only unlock for an ID swipe. With the kids badges opening doors they need to get into (main doors, bathrooms, even classrooms for their specific classes) and Staff cards open most doors. Then the guy with a gun comes to the campus and can't get in the door to start with (unless they shoot out the lock but that starts police response) The campus is more safe because most doors are closed and locked by default making it harder to go from room to room.
I think these things are a privacy night mare. Most kids will keep them in purses or wallets, if I worked in retail the first thing I do is place readers by the doors and checkout registers that ping the cards since I can read them in someones purse or pocket. I only get a number but I will know how often that number enters the store, when and what they spend money on. If they use a credit card at checkout I now know the name of the person and can attach it to the ID number. There are no laws preventing me from doing this. If the tags where passive this would be almost impossible.
