Indeed, society has yet to answer such basic questions as whether an implanted tag is the property of the person it's implanted in or the company that issued the tag. When you leave a job, you typically turn in your keys, Foster and Jaeger point out. Would you have to have an implant surgically removed with each job change?
Although mandating that everyone be chipped seems far from likely, Jaeger and Foster are concerned that supposedly voluntary implantation would be anything but. Responding to a proposal to chip guest workers entering the United States for employment, they write: "Guest workers might ostensibly consent to having chips implanted. But would chipping them be truly voluntary? Such 'voluntary' actions may determine a person's ability to earn a living, and the worker might not view the implantation as something he or she could refuse. What person facing poverty at home and given the prospect of a job in a different country would be in a position to argue?"
With thousands of people already implanted, it's past time to answer these thorny questions.
