"Like any tech advancement, there are downsides. Concerns about the wrong people accessing personal information and tracking you via the chips have swirled since the FDA approved the first implantable microchip in 2004.
Naam and Pang both cited potential abuses, from hacking into the infrastructure and stealing your identity to invading your privacy and knowing your driving habits. There are questions about how long a felon would have to use a tracking implant. And, an implant, which has to be small and not use battery power -- might not be as secure as a heavily encrypted smartphone.
Troy Dunn, who attempts to locate missing persons on his TNT show “APB with Troy Dunn,” said a chip implant would make his job easier, but he is strongly against the practice for most people. “I only support GPS chip monitoring for convicted felons while in prison and on parole; for sex offenders forever; and for children if parents opt in,” he says. “I am adamantly against the chipping of anyone else.”
Using chip implants to locate abducted children could actually have the opposite effect. Pang says a microchip would make a missing person easier to rescue, but “Kidnappers want ransoms, not dead bodies. The most dangerous time for victims is during rescue attempts or when the kidnappers think the police are closing in.”
And beyond the obvious privacy issues, there’s something strange about injecting a chip in your body, Lipoff says. Yet pacemakers and other embedded devices are commonly used today. “People might find it a bit unsavory, but if it is not used to track you, and apart from the privacy issues, there are many interesting applications,” he says.
At least it’s better than having a barcode stitched onto our foreheads."
