When William Koretsky's car crashed at high speed in May 2006, the unconscious police sergeant couldn't tell doctors about his type 1 diabetes. His RFID implant did it for him. A quick scan of his arm revealed a 16-digit code that pulled up his complete medical history, making him the first emergency patient ever identified by a chip embedded in his body. The technology that had spent decades tracking shipping pallets and retail inventory had just proven it could save a human life.
From Warehouses to Flesh
RFID didn't start as a biohacking tool. During World War II, Sir Robert Alexander Watson-Watt developed radio frequency signals to distinguish friendly aircraft from enemy planes—the original "Identify Friend or Foe" system. By the 1970s, Charles Walton had miniaturized the concept into a passive transponder that could unlock doors. Retailers loved it. Wal-Mart, Tesco, and the U.S. Department of Defense deployed RFID tags across their supply chains, tracking millions of products with invisible radio waves.
The leap from cardboard boxes to human tissue happened in 1998 with the first documented human implant. But the technology remained a curiosity until 2004, when the FDA approved VeriChip—a glass cylinder the size of a rice grain—as the world's first implantable identification device for humans.
The pitch was simple: inject a 12mm chip under your skin, and emergency responders could scan your arm to access your medical records. For $200 to $400 upfront plus $20 to $80 annually in database fees, you'd never be an anonymous patient again. VeriChip identified 45 million at-risk Americans who might benefit: diabetics, cardiac patients, people with Alzheimer's, anyone with a condition that could render them unable to communicate.
The Corporate Chip Party
On August 1, 2017, something shifted. Three Square Market, a Wisconsin vending machine company, threw a "chip party" for its employees. Fifty of the company's 80 workers lined up to have RFID chips injected between their thumbs and forefingers. CEO Todd Westby compared the sensation to "somebody stepping on a pinky toe with a dress shoe on." The procedure took seconds.
These weren't medical chips. Partnering with Swedish company BioHax, Three Square Market deployed workplace chips that opened doors, logged into computers, operated copy machines, and purchased snacks from break-room kiosks. Wave your hand, get a Coke. No badges, no passwords, no wallet required.
The 62.5% participation rate was striking. This wasn't a medical necessity or a security mandate—it was voluntary convenience. And the chips were permanent. Employees who left the company would keep their implants, though whether they'd still function for anything useful remained unclear.
Three Square Market insisted the chips had no GPS capability, though Westby noted future versions could include tracking. That distinction matters less than it seems. The chips are passive devices, only transmitting when activated by an external scanner. They can't broadcast your location to satellites. But every door you open, every computer you access, every purchase you make creates a digital trail of exactly where you've been and when.
The Body Rejects What It Doesn't Recognize
The medical community has been less enthusiastic than tech evangelists. Hand surgeons have raised concerns about implantation occurring outside medical environments, often performed by technicians rather than physicians. The potential complications read like a warning label: infection, tendon damage, toxic metal absorption, allergic reactions to anything that isn't 100% silicone.
Manufacturers treat chips with chemicals to prevent them from migrating through tissue, but bodies don't always cooperate with engineering specifications. Long-term health effects remain poorly studied, partly because the technology is too new and partly because voluntary human experimentation doesn't generate the same research funding as pharmaceutical trials.
The database security issues cut deeper than physical safety. VeriChip's terms and conditions explicitly exclude the company from liability for hacking, data breaches, or information accuracy. Your medical history sits in a password-protected online database, accessible to anyone with a scanner and your 16-digit code. The European Group on Ethics in Science and New Technologies examined RFID implants in 2005 and found the privacy implications troubling enough that Europeans and Canadians—with stronger privacy traditions than Americans—showed greater resistance to adoption.
Wisconsin passed a law in 2006 prohibiting forced implantation without consent, a protection that sounds reassuring until you consider it had to be written at all.
The Voluntary Surveillance State
The biohacking movement frames RFID implants as human augmentation, a way to merge with technology rather than merely use it. But the trajectory from Koretsky's life-saving emergency scan to Three Square Market's break-room purchases reveals something more ambiguous. We're not just tracking humans the way we track inventory—we're adopting the same logic that made inventory tracking valuable in the first place: efficiency, convenience, and the elimination of friction.
Every technology that embeds itself in daily life does so by solving a small problem. RFID tags made supply chains faster. Implanted chips make medical emergencies safer and office buildings more convenient. Each use case sounds reasonable in isolation. The pattern only becomes visible when you step back and see how voluntary adoption creates infrastructure that assumes everyone will eventually participate.
IDTechEx projected the healthcare RFID market would grow from $90 million in 2006 to $2.1 billion by 2016, making it the second-largest application after retail. Those numbers suggest an industry betting that the question isn't whether humans will be chipped, but how quickly we'll accept it as normal.
Koretsky's chip saved his life. Three Square Market's employees gained convenience. Both outcomes are real. So is the fact that a technology designed to track objects has found its most enthusiastic adopters among people willing to become objects themselves—scannable, trackable, and permanently logged in a database they don't control.
