There's not a lot of middle ground on the subject of implanting electronic identification chips in humans.

Advocates of technologies like radio frequency identification tags say their potentially life-saving benefits far outweigh any Orwellian concerns about privacy. RFID tags sewn into clothing or even embedded under people's skin could curb identity theft, help identify disaster victims and improve medical care, they say.

Critics, however, say such technologies would make it easier for government agencies to track a person's every movement and allow widespread invasion of privacy. Abuse could take countless other forms, including corporations surreptitiously identifying shoppers for relentless sales pitches. Critics also speculate about a day when people's possessions will be tagged -- allowing nosy subway riders with the right technology to examine the contents of nearby purses and backpacks.

"Invasion of privacy is going to be impossible to avoid," said Katherine Albrecht, the founder and director of Consumers Against Supermarket Privacy Invasion and Numbering, or CASPIAN, a watchdog group created to monitor the use of data collected in the so-called loyalty programs used increasingly by supermarkets. Albrecht worries about a day when "every physical item is registered to its owner".

The overriding idea behind tagging people with chips -- whether through implants or wearable devices such as bracelets -- is to improve identification and, consequently, tighten access to restricted information or physical areas.

But on top of civil liberties and other policy issues, such technologies face visceral objections from many people who frown on the idea of being implanted with tags that can track them like migrating tuna. Complaints have led several companies to abandon plans to use RFID technologies in products, much less in human bodies.

The concept of implanting chips for tracking purposes was introduced to the general public more than a decade ago, when pet owners began using them to keep tabs on dogs and cats. The notion of embedding RFID tags in the human body, though, remained largely theoretical until the 11 September, 2001, terrorist attacks, when a technology executive saw firefighters writing their badge numbers on their arms so that they could be identified in case they became disfigured or trapped.

Richard Seelig, vice president of medical applications at security specialist Applied Digital Solutions, inserted a tracking tag in his own arm and told the company's chief executive that it worked. A new product, the VeriChip, was born.
