Gentlemen, take your tinfoil hats out. The time is near when you’ll be a likely candidate to be sprinkled with RFID powder. It’s a little bit like Pixie dust, except this dust lets Big Brother keep a better eye on you. What is this, you say? Well, seems Hitachi recently announced the development of the world’s smallest RFID chip, at 0.05mm square. That’s actually 64 times smaller than the Mu-Chip you see on that dude’s thumb. The new chip, pictured on the right next to a human hair, is 5 microns thick, and will have a 128-bit ROM for storing a unique 38-digit ID number.
Aside from the obvious (and severely paranoid) applications, we could start seeing these being embedded in currency, ID cards and even gift certificates. Hitachi plans to bring this to market within 2 to 3 years.
