Just hack the cards like Dems make up voter registrations with names such as Mickey Mouse and Adolf Hitler.

Principal: Mrs. Johnson will you please find out where Junior Barnes is located at this moment?
Mrs. Johnson: I can’t find him, sir, but I can see some little Hitler, Mickey Mouse, Bruce Springsteen, and Frank Sinatra are in the building!

If you're going to go to that much trouble - just jimmy the system so anybody authorizes everybody in the classroom.

Actually, for the motivated, no hacking is required. But at best, you could masquerade as someone. There are 2 types of RFID tokens, one RO and one is programmable (and different systems operate on different frequencies). The only information the card transmits is a very long unique serial number. Once read into the system, it looks up the serial number in it's internal database to see who the token belongs to. All you need to know is what frequency the system runs on (easy to find out) and you can buy a programmable token and make it whatever you want. This is why truly high security situations demand 2 factor or more for authentication... RFID-token+fingerprint for instance.

The point is to resist the concept openly and reject the ideal that the entity has the right to track you, trumping your individual rights. It's no different than helping the police without warrant bust down your neighbors door as long as they secretly agree to not bust down yours...
