If that sounds far-fetched, you obviously haven't been to Sweden recently, where thousands of people have reportedly had chips implanted in their bodies.
A company called Biohax has already "installed" around 4,000 chips in customers, inserted just below the thumb. They can use the implant to open secure doors, pay for tickets, and share emergency information with medical personnel. The chip is about the size of a Tylenol pill, and the procedure -- which costs $180 -- is similar to getting a tetanus shot.
"The chip implant is a secure way of ensuring that a person's digital identity is linked to their physical identity. It enables access management in a way that protects individual self-sovereignty and allows users to control the privacy of their online activity," Dr. Stewart Southey, the Chief Medical Officer at Biohax International, told Fox News.
Another doctor agrees that getting "chipped" is practical and even advantageous. As far back as 2014, experts have outlined a number of benefits, some medical and some consumer-based.
"From a medical perspective, in the ER we have patients come in every day who are confused or comatose and we cannot get any medical history from them," says Dr. Larry Burchett, a medical expert and author who runs DoctorLarry.com. "If we had access to that info because they have a chip in their skin, that could be lifesaving."
