Employees at a Wisconsin tech company are volunteering to have microchips implanted into their hands. The chips, equipped with radio-frequency identification technology, will open doors, grant food purchases in the break room, speed up computer log-ins and provide access to copy machines. More than 50 of the company's 80 employees have opted in to the voluntary program.

But attorneys seem less thrilled about the idea. Private practice labor lawyers brought up issues of worker privacy, data collection policies, data misuse and medical liability, while one general counsel questioned the business goals and costs of the program.

“It's interesting, but the way I see it, unless there's a real need in an organization for driving accountability and tracking, it doesn't make business sense for me as a manager or executive in an organization,” said John Kuo, general counsel of medical device company Varian Medical Systems. “Why not just let your employees wear card keys that have RFID technology?”
