Microchips in everything: threat of privacy invasion?

A video screen in a grocery store showing ads to you because of a radio frequency ID (RFID) chip in your shoe? Could happen, says privacy lobbyist Katherine Albrecht. She fears the chips, which currently cost less than a dime and don't contain batteries, will be installed everywhere. If that occurs, she says, "You've essentially created a world in which there is no privacy." But a spokesman for Gillette says the primary use of RFID chips will be to reduce the cost of misplaced or stolen inventory. "We have no interest in collecting data beyond the shelf," he says. Albrecht counters that any technology is likely to be abused unless it's regulated. (Source: corante.com)
