"The piercer — whose day is usually spent inserting rings into the eyebrows and navels of teenage girls — snapped on purple latex gloves and lifted a four-millimeter-wide sterilized needle to William Donelson's hand.

'I'm set,' Mr. Donelson said with a deep breath. He watched as the needle pierced the fleshy webbing between his thumb and forefinger and a microchip was slid under his skin. At last he would be able to do what he had long imagined: enhance his body's powers through technology.

By inserting the chip, a radio frequency identification device, Mr. Donelson would literally have at his fingertips the same magic that makes security gates swing open with a swipe of a card, and bridge and tunnel traffic flow smoothly with an E-ZPass. With a wave of his hand he planned to log on to his computer, open doors and unlock his car."
