  • Enter Cyborg: the Dawn of Human Microchips

    When biohacker and magician Anastasia Synn holds her phone over her heart, it speaks: “This is the day I married my best friend.” Her wedding video begins to play.

    A small, glass-encased microchip implanted under her skin holds close the memory of her marriage to fellow magician The Amazing Johnathan. Next to it, another implant holds his ashes. They were previously implanted in her arm, alongside a magnet, so Johnathan could keep performing his favorite trick after his 2022 death.

    “After my husband died, I wanted to have his ashes implanted, and it just made sense to have our wedding video, have his funeral video,” Synn said. “I had a chip that told his favorite joke, and I have one in my hand that calls his phone. I don’t scan them all the time, because it’s emotional for me still.”

    The microchips — more specifically, radio frequency identification tags, which operate without a power source — can be programmed to trigger different actions. Synn had her first chip trigger a fat noise on her phone. Some of her chips are functional, like the one that serves as her housekey.

    Though functionality would become the dominant use of RFID chips, the first human implantation was an artistic endeavor by Brazilian artist Eduardo Kac in 1997. Kac implanted an RFID chip meant for animals into his ankle, and added himself to a U.S. pet ID registry in a project titled “Time Capsule.” He still has the implant today.

    In 1998, University of Reading professor Kevin Warwick had a small RFID tag implanted in his arm for 10 days. He, not Kac, is commonly identified as the first human to receive such an implant. Because the chips are unpowered, they are limited in range. Still, Warwick’s chip could be programmed to open doors ahead of him and log into computers, both of which remain popular applications of RFID implants. 

    When the DIY-cybernetics community coalesced around implanted chips, they followed in Warwick’s footsteps, creating new ways to interact with their environment and devices. At home and in garages, they pursued a transhumanist vision by pushing the limits of human capability. It was in this environment that Amal Graafstra, who had his first chip implanted in 2005, decided to start Dangerous Things, now a leading RFID implant manufacturer.

    “I started seeing a lot of people doing implant installations using stuff they were pulling out of car keys, doing it in a haphazard way,” Graafstra said. As a business, he wanted to “focus on two things: One, making sure the thing people are putting in their body is actually safe, and two, the way they’re getting installed is actually safe.”

    Constructing body-safe chips was straightforward enough: Dangerous Things source their own materials before manufacture and do batch testing for quality control. Nothing goes in that isn’t vetted, and defects are caught early — Synn herself prefers Dangerous Things’ glass-encased RFID chips for longevity. 

    Safe installation would take a bit more work. Even the easy installs, like smaller chips that can be inserted with a needle, require sterility and a level of anatomical knowledge. Graafstra turned to piercers, attending the annual Association of Professional Piercers conference and explaining the technology.

    Today, Dangerous Things has an array of installation partners — body modification artists who can safely install the chips. One of them is Katie Lynn Patterson, a Texas-based body piercer at Stubborn Anchor Studios, who does a few installations a month. While she doesn’t have implants herself, she sees biohacking as a natural extension of body modification.

    “I was so in love with the idea that a human can customize themselves, push their bodies to their limits, and ascend to a higher state of mind,” she said. “That later came to include embracing the modern marriage between body modification and technology, and its relation to the future of biohacking.”

    According to Patterson, healing and aftercare for the microchip implants is relatively fast — full healing usually takes up to four weeks with precautions like cleaning the implant site and minimizing movement. The wound itself typically closes within a week, but the body needs more time to create a pocket of scar tissue that helps anchor the device. While the procedure has similar risks to getting a piercing — rejection, infection, migration, irritation, and scarring — these can be minimized by proper, safe installation from an experienced artist.

    Though Graafstra would eventually come to work closely with body modification professionals like Patterson, he didn’t consider himself part of the body modification community, at least at first. He had no tattoos or piercings, seeing them as an aesthetic addition he had no interest in. Shortly after his first implant in 2005 went viral, however, BME covered the story

    “It never really crossed my mind as a body mod in that way — it was, for me, just a practical, functional thing,” Graafstra said. “It really opened me up to the idea that there might be a philosophical and psychological aspect to this, rather than just the pragmatic aspect of enhancement capabilities.”

    For Graafstra, the philosophical aspect now has a new dimension: With the rapid rise of generative AI, he’s concerned that verifying someone’s identity, or even humanity, online is growing increasingly difficult. While some have proposed biometric data as a better identification tool, Graafstra’s not convinced. It’s too easy to fake, he says, and erodes an individual’s ability to remain private — with gait analysis and facial recognition, any camera is a means for revealing identity. He argues that public key encryption, like that used for accessing Bitcoin wallets, could be a solution. 

    The biggest downside of such systems is their unbreakableness: “if you lose your key, you’re fucked,” Graafstra said. But if the key is stored on an implanted RFID tag, “your digital identity and your biological identity are together.”

    It’s not something he expects to see anytime soon, if ever. But it is an inversion of a commonly expressed fear about microchip implants. 

    Even back in 1998, Warwick raised concerns about implanted RFID tags being used by employers to track employees, down to monitoring time spent in bathrooms. In 2004, after the Food and Drug Administration approved VeriChip, the first human-use microchip, similar concerns emerged about potential government tracking. According to documents filed with the Securities Exchange Commission, the company that owned VeriChip ceased actively marketing it in 2008 after sales lagged significantly behind projections. And during the COVID-19 pandemic, conspiracy theories about microchips in vaccines spread, often accusing global elites of planning the pandemic as an excuse to inject the world population with tracking devices.

    The concerns have led to legal action: 13 states have issued preemptive bans on businesses requiring employees to get chipped. In 2019, Nevada went further, introducing an Assembly bill threatening anyone who established or participated in a voluntary implantation program with a felony conviction. Though it passed unanimously in the Assembly, it faced a harder fight in the Nevada Senate when local biohackers showed up to counter the bill. 

    Synn, who had just returned to Las Vegas after touring with her husband, attended at the urging of two biohacker friends. She was frustrated to see that misunderstandings of the technology seemed to be a major motivation for the bill. 

    “I babbled for, like, eight minutes straight without letting them get a word in edgewise,” Synn said. “And then I stopped. One senator looks at me, and she just laughs, and looks at everyone else. And she goes ‘ok, so, wow, thank you. We did not know any of that, thank you.’ And that senator voted against the bill.”

    The law Nevada eventually passed only restricted coerced implantation, in line with other states’ bans, and even included language clarifying that it did not forbid voluntary implants. Synn was even invited back to talk to legislators about transhumanism.

    It’s a moment she’s proud of. Synn herself had been somewhat skeptical at first, but quickly fell in love with the magnets and chips she had implanted. She now has so many she’s lost the exact count, but it’s somewhere around 54. And she’s always happy to “spread the cyborg love” by giving others their first implant.

    “It’s fun just to make yourself something more than you are,” she said. “I don’t charge people for it, and usually I even give them the chips for free … so I feel like I’m the spreader of the cyborg myth. You want to become a cyborg? I got you. It’s free. I’ll help you out, right here, right now.”

    Amal Graafstra Gets an RFID Implant

    “The future is here.
    It’s just not widely distributed yet.”

    -William Gibson

    Of all the fears associated with the technological advancements of the computer age — and there are many — the most long-standing and pervasive is, arguably, humans being tagged and monitored in some fashion, often either by bar codes

    or microchips. And it’s not an entirely unfounded fear; outfitting pet animals with chips has become standard procedure for identity purposes, and has generally met with great success. Small, low-frequency RFID (Radio Frequency IDentification) tags are encoded with information about the subject and are subsequently embedded in them, rendering their details available to anybody within arm’s reach — who happens to have an RFID reader. Even with basic knowledge about the technology, it’s quite easy to imagine the potentially frightening implementations of it. Needless to say, convincing humans that an RFID implant is right for them can be a hard sell; even ostensibly useful applications of the technology, such as Spanish clubs offering their VIP customers the option of receiving an implant that acts as a debit card — so as to avoid carrying a wallet or purse — can be revealed for their sinister capabilities.

    Does Biblical Scripture
    warn us of the coming
    of Amal Graafstra?

    That’s the wonderful thing about technology though — as scary and awful as some may find specific uses of certain things, there are always those who can see the other side of the coin. In this case it’s Amal Graafstra, a Washington state native and business owner who recently underwent the minor procedure of getting an RFID implant in his left hand, and has lightly documented the process on his personal web site. A lifelong tinkerer, Amal describes himself as the kind of guy who, if he lost an arm in a horrible accident, would be “totally bummed about losing my beloved arm, but also kind of excited about what kind of bionic apparatus I might get to tinker with as an experiment.” Eventually, he’d like to outfit everything from his car to his home with sensors; BME recently spoke to Amal about his venture into the world of implant technology.

    BME:

    What’s your background with RFID technology?

    AG:

    I have no RFID background at this point, though I do have an extensive tinkering and gadgetry background. I like to mod things, and I g.uess it was only natural that it extended to my own body. I became interested in RFID and other alternate means of identification a while back. I constantly lose my keys and my wallet — yeah, I’m one of those guys. So I was sitting around thinking about keys and credit cards, and the obvious truth that these chunks of metal and pieces of plastic were really representing me and basically identifying me to whatever mechanisms and systems they worked with, be it my front door deadbolt or my bank account. I basically just wanted to get rid of my keys and wallet.

    BME:

    Why choose RFID over other similar technologies?

    AG:

    Well, a lot of people ask why not use BioMetrics, the approach that uses your own body and features to identify you… and I guess I have my own Big Brother paranoia. Given the choice of Orwellian societies, I’d rather live in one based on RFID tags than fingerprints, DNA, or facial structure; an RFID tag system is easy to manage and opt out of, whereas DNA sampling or facial recognition, well, isn’t. As for the future of my involvement with RFID past my own projects, I’m already talking to many of my clients — I provide services to medical clinics and other medical related industries — for tracking products and items, such as blood test vials, throughout the entire process: From collection to testing to storage, and eventually to disposal or whatever it’s final destination is.

    BME:

    What are the specifications of your implant? Are there more powerful options available?

    AG:

    I have no RFID background at this point, though I do have an extensive tinkering and gadgetry background. I like to mod things, and I guess it was only natural that it extended to my own body. I became interested in RFID and other alternate means of identification a while back. I constantly lose my keys and my wallet — yeah, I’m one of those guys. So I was sitting around thinking about keys and credit cards, and the obvious truth that these chunks of metal and pieces of plastic were really representing me and basically identifying me to whatever mechanisms and systems they worked with, be it my front door deadbolt or my bank account. I basically just wanted to get rid of my keys and wallet.

    BME:

    You mean for security purposes? That seems like it would be a concern, considering your desired uses for the technology (home and automobile entry, wallet replacement, and so on).

    AG:

    Yeah. Though there is already encryption in use with RFID tags; gas pumps that use those keyfob speedpasses are based on encrypted RFID. There are RFID chips in car keys already that are encrypted and use a challenge/response system to ensure you can’t fake it, but these systems have already been cracked. As far as I know, there aren’t any implant-grade chips that even offer this encryption yet.

    For me personally though, with the read range being only an inch, stealing my RFID tag ID would be a rather personal encounter. Getting that tag ID duplicated would be another difficult task for your average carjacker — it would honestly be easier to just smash my window. I could also employ a two-phase system that would require my chip ID and, say, a voice recognition pattern match, a fingerprint match, or some other quick method of identification if it came down to it — maybe even detecting my Bluetooth enabled cell phone would be enough. Bottom line though, any security system you employ can be hacked, thwarted, or otherwise subverted — even deadbolt locks. It takes me about ten minutes to pick a good deadbolt lock with a $30 lock pick set; I once let a friend into his house by picking his deadbolt and his doorknob lock in less than five minutes. It really shook him up that it was so easy to get in, but I pointed out that anyone can break a window or “credit card” the door-jam just as easily. 99% of the day, we feel safe because of the illusion of security, not the actual existence of it. Take driving for example… you rely on others to stay on their side of the line; your life is in the hands of every driver around you.

    BME:

    Now, who actually performed the implant procedure?

    AG:

    As I have not asked the doctor for permission to publish their name, I can’t give that out, but they happen to be a cosmetic surgeon, so it seemed the natural choice. However, it was not hard to find someone to do the procedure; I have many MDs for clients and the day I got my chips, I asked two and both said they’d do it. I also stopped into a tattoo shop and asked them if they’d do the procedure and, while they couldn’t help me, they gave me the number of someone who does body mods and said they would probably do it without a problem. However, since I had two willing MDs I didn’t bother following up — I was just curious to see how hard it might be to get someone to put this thing in me.

    BME:

    Can you walk me through the procedure itself?

    AG:

    Sure, it was actually rather simple. Normally, the RFID chip is implanted with a needle and syringe and is as simple as a swab of anesthetic, inject, band-aid, done. However, we couldn’t find a needle 2mm in size in stock, so we resorted to a scalpel. The chip itself was placed into a container with a powerful disinfectant. I was asked if I had any allergies to any medications or latex or anything like that, and I then washed my hands with soap. The tools were taken out of their sealed sterile bags, and I was told not to touch them or the clean sheet on the little table, so I just sat down in a chair and my hand was swabbed with some form of disinfectant. From the color of it, I’d guess it was iodine based. A local anesthesthetic was injected (because I’m kind of a wussy), and within a minute we were cutting into my skin. The chip itself is encased in glass and is solid inside, probably containing some kind of epoxy resin of some sort, so there is little chance of crushing or breaking it. The chip was removed from the liquid it was soaking in with metal tongs and dried, then inserted into the cut.

    The chip is placed between the skin layer (all the way under the skin) and the muscle layer, but honestly, it could have gone anywhere. The main concern is migration and read-range. You don’t want a chip too deep to get an effective read from, but you also don’t want it scooting around under your skin once it’s in. This implant surface has nothing on it; it’s simply glass touching my body. However, the implants dogs and cats get normally have a “cup” or half-coating on them which is a porous polypropylene polymer sheath that allows development of fibrocytes and collagen fibers to grow around the implant and impede migration. The doctor wasn’t too worried about my implant moving around on me though — and really the only problem if it does move is knowing where it is so you can scan it!

    After the chip was in place, the doc used skin glue instead of stitches to close it up. After it was closed, some steri-strips were placed over the site to help hold it together, and then a non-stick gauze bandage pad was taped over top, then some really fancy loose gauze was wrapped around my hand, making me look like a burn victim. I was told not to flex or move my left hand or use it for anything for at least a couple days. I was then given the standard, “if it gets red or infected call me, etc.” patient care information. The whole procedure took about five minutes to prep for, one minute to actually perform, and five minutes to bandage up and go through the patient care information.

    BME:

    How did it feel? Do you maybe have any piercings or tattoos you could compare it to?

    AG:

    I don’t actually have any modifications myself, aside from this RFID tag now. But, I am planning on getting at least two tattoos sometime soon; once my left hand is healed up, I plan on getting the kanji for patience in the webbing between thumb and index finger — basically overtop the RFID tag. In the same place on my right hand, I plan on getting the kanji for now, but I may wait a while; I’m still deciding if I want to put another RFID chip into my right hand. Aside from that, I like to look at female nipple piercing.

    As for the implant, it was odd feeling it being pushed under the surface of my skin. Without feeling pain, I was able to really get a feel for just how utilitarian our bodies actually are and how separate everything is — how separate the skin layer really is from the muscle layer under it. It really is just a rubbery protective coating. Complex and amazing, but far less mysterious to me now.

    Also, I had never had skin glue on me before and had my doubts — especially since I went right out and disobeyed the doctor’s orders. Only an hour after the procedure, I had to move a bunch of rack mount servers from one rack to another — a two hour process of lifting and using a screwdriver and such. I babied that hand, but as the anesthesia wore off, I could feel a little bit of pain in it. I pressed on though, confident my skin glue had come apart. However, when I took off the outer bandages things looked fine, no blood or tearing.

    BME:

    Was there an aftercare process you had to follow?

    AG:

    Not really, just to keep it dry; let it heal up; don’t take off the steri-strips, just let them fall off on their own. After a few days the skin was strong enough to hold up to almost normal use of the hand. But after moving servers all night, the next few days of typing and paper pushing were cake compared.

    BME:

    Do you notice the implant at all?

    AG:

    Not at all, really, aside from a slight sensitivity around the implant site. I’m sure the sensitivity will pass and it will be completely unobtrusive.

    BME:

    Are you happy with the results so far?

    AG:

    I am. The biggest challenge will be to come up with a computer system stable and reliable enough to let me in the door; that will be the real test. Ultimately, I will have to get an encrypted tag and find a sensor that can read the tag and interface well with a PC as well as a microcontroller, such as a BASIC STAMP or PIC processor. Chances are, the only reliable hardware I’ll be able to come up with is a dedicated microcontroller that can be programmed with “allowed” tags via a PC… but the actual work of letting people in the door will be done by microcontroller. That removes the stability, and power consumption of the PC, from the equation.

    NOTE: Amal does not have a Verichip!

    BME:

    Ideally, what sort of accessibility do you hope to see this implant give you in the future?

    AG:

    Well, because I’m writing my own software and soldering up my own stuff, pretty much anything I want. Well, more accurately, anything I have the time and inspiration to do. Ultimately though, I think true keyless access will require an implantable chip with a very strong encryption system; right now I’m only looking at this type of thing in a personal context.

    As for society at large, nightclubs in Spain are already using RFID chips to let customers put drinks on their tabs and enter VIP lounge areas, and I think Australian pubs are doing the same as well. I’m not sure if they use encrypted implants or not. I was more interested in just getting something simple, cheap, and fun to play with.

    The chip itself is only $1.50, and I was able to get a 125KHz sensor/reader for $50, so the total project cost so far is about $60 with shipping and everything. An electronic strike for the front door will probably run anywhere from $50 to $80 I’d imagine, and the time and cables to get it all hooked up to a computer. The biggest issue for keyless entry, besides security concerns, is the computer. I need to keep a working, stable, reliable computer running at all times to monitor the sensor and activate the door strike to let me in. For the car though, this is not practical. There are other alternatives including microcontrollers that would work, but the main thing is that you need power for this system to work. So really, keyless entry is only a luxury… I’d still have to carry keys around in my pocket — I just hope the number of keys could be reduced. A car key would not be required, as you would not be going anywhere fast with a dead car battery anyways, but a house key might be nice if the power was out and you couldn’t get in.

    Amal’s approach to impending technology is likely one of the best there is: Get to know it personally, learn how to use it properly, and don’t let it take advantage of you. If his experiment works as planned, he’ll have taken a bold step in a direction that many of us have purposefully avoided and made it work for him. Or, in his own words: “It’s one small step for hand, one giant leap for keyless entry.

    Follow-up Letter:

    Hey Jordan,

    I just ran across your RFID article with Amal. I couldn’t believe what I was reading, especially since I sold him the RFID chip and reader! I remember him asking about the biobond stuff and now I know why. I had no idea someone was going to be crazy techie enough to put one in their own hand. Wild.

    Anyhow, I was surprised to see a whole article about someone using an RFID reader and chip from us with no mention or link.

    I have no idea what policies the site has about such things, but I’m a small business doing everything I can to grow and I think this article will generate some publicity and would love to let people know where the RFID reader + chip came from.
