Logging onto your computer may become as easy as waving your hand. Radio frequency identification computer chips may be what makes it all possible.

Inserted into the hand, the computer chips have already improved life for Amal Graafstra, a 29-year-old entrepreneur based in Vancouver, Canada, according to Reuters

"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 told Reuters. "RFID is for me."

The chips cost about $2 and are activated when they come within three inches of a reader, which is installed in computers and other electronic equipment. The reader can be bought for about $50.

Graafstra said several of his friends have the implants.

"I can't feel it at all. It doesn't impede me. It doesn't hurt at all. I almost can't tell it's there," agreed Jennifer Tomblin, a 23-year-old marketing student and Graafstra's girlfriend.
