One step up from trepanation (ok, maybe two), some overly enthusiastic techies now are self-chipping themselves with Radio Frequency Identification (RFID) tags. RFID tags are contactless chips which are great at (for instance) counting a palletfull of boxed Wal-Mart crap at the loading dock. A reader held a few inches from something with a tag can pick up information about what the tagged item is, where it came from, how long it took to get there, and the like.
Unfortunately for would-be Bionic Cyberboys, the limited range and underwhelming consumer applications for these tags so far makes the self-chipping thing pretty weak. While the guy who was getting this surgery thought he'd be moving walls from afar as he pranced through his secret lair all Magneto-style, back in the real world he can unlock a screen saver or his front door. Yay.
