This year we are trying something new with our First Year students. Each new student is being given a little RFID tag to put on their keyring. Then we are going to try and use these to make lectures and social events a bit more fun, starting with the welcome party for new arrivals.
Normally we hand out free drinks tokens to students who can then exchange them at the bar for whatever they fancy. But that doesn't sound very high tech to me.
This year we are using the "tags of fun" instead. The "Tagomatic" at the bar will read each tag and register the student for a drink. Then we can reset the device when it is time for the second round. We will also be using the tags in lectures to award silly spot prizes.
