For a couple of years now, I've had my eye on the community of people who've had RFID or NFC chips implanted somewhere in their bodies, usually in the back of the hand. If you've ever used a badge to unlock a door at work or tapped your phone on a point-of-sale terminal to buy something, you've used one of these two technologies in your everyday life to do something useful. What I've wanted to do for a while was use an implanted chip as a second authentication factor to my servers for better security. As for why I couldn't just use something like a key fob or a card or something.. there were a bunch of reasons, most of them having to do with only being able to find what I needed in bulk or the cost being too high because the equipment was aimed at corporate IT departments, where they have a need to crank out a couple of dozen ID badges an hour. There is also the fact that, while I've been curious about various forms of body modification over the years I never really got into into them for a couple of reasons that probably aren't terribly interesting so why not do something useful?
Due to the fact that not everybody is going to be okay with me talking about an elective medical procedure, I'm going to put the rest of this article after the fold.
