Computer chips get under skin of enthusiasts

With a wave of his hand, Amal Graafstra, a 29-year-old entrepreneur based in Vancouver, Canada, opens his front door. With another, he logs onto his computer.

Tiny radio frequency identification (RFID) computer chips inserted into Graafstra's hands make it all possible.

"I just don't want to be without access to the things that I need to get access to. In the worst case scenario, if I'm in the alley naked, I want to still be able to get in (my house)," Graafstra said in an interview in New York, where he is promoting the technology. "RFID is for me."

The computer chips, which cost about $2, interact with a device installed in computers and other electronics. The chips are activated when they come within 3 inches of a so-called reader, which scans the data on the chips. The "reader" devices are available for as little as $50.

Information about where to buy the chips and readers is available online at the "tagged" forum, (http://tagged.kaos.gen.nz/) where enthusiasts of the technology chat and share information.
