Hold a fluorescent light bulb near this table and it will suddenly flicker on. It looks like magic, but it's simple science: An embedded circuit produces an electromagnetic field that acts on the mercury gas inside the bulbs, making them glow as if they're plugged in.
Sometimes it's the unseen that's the most terrifying. In the case of RFID we think there's plenty to dread, but never actually looked at those scary, scary waves. Thankfully someone at the Oslo School of Architecture and Design did.
