Regine at We Make Money Not Art has a great set of interviews up with artists using RFID. She writes:

I interviewed 5 artists (Paula Roush, Doria Fan, Joshua Klein, David Kousemaker and Meghan Trainor) as well as our favourite expert from Tokyo (Konomi Shin’ishi) about their experience with RFID technology. What comes below doesn’t reflect my presentation which was focusing on the ethical and cultural implications of the technology. I used these interviews as background research and thought they might be useful mainly for the workshop participants but also for some readers

The words of these artists are inspiring and it’s great to see what they’re up to. Check it out!
