A subset of hackers have RFID implants, but there is a limited catalog. When [Miana] looked for a device that would open a secure door at her work, she did not find the implant she needed, even though the lock was susceptible to cloned-chip attacks. Since no one made the implant, she set herself to the task. [Miana] is no stranger to implants, with 26 at the time of her talk at DEFCON31, including a couple of custom glowing ones, but this was her first venture into electronic implants. Or electronics at all. The full video after the break describes the important terms.
The PCB antenna in an RFID circuit must be accurately tuned, which is this project’s crux. Simulators exist to design and test virtual antennas, but they are priced for corporations, not individuals. Even with simulators, you have to know the specifics of your chip, and [Miana] could not buy the bare chips or find a datasheet. She bought a pack of iCLASS cards from the manufacturer and dissolved the PVC with acetone to measure the chip’s capacitance. Later, she found the datasheet and confirmed her readings. There are calculators in lieu of a simulator, so there was enough information to design a PCB and place an order.
The first batch of units can only trigger the base station from one position. To make the second version, [Miana] bought a Vector Network Analyzer to see which frequency the chip and antenna resonated. The solution to making adjustments after printing is to add a capacitor to the circuit, and its size will tune the system. The updated design works so a populated board is coated and implanted, and you can see an animated loop of [Miana] opening the lock with her bare hand.
Biohacking can be anything from improving how we read our heart rate to implanting a Raspberry Pi.

“And then they feasted on snuff and cold cuts of meat at the local inn”
Wonderful. You get fired you end up with a useless implant.
There is a very likely chance that your next employer with have a compatible system!
WEF compliance will see to it.
And every time somebody clones your tag ID you have to cut the thing out and replace it.
Most of them are reprogrammable by design. That’s never been an issue for me
Hey, thanks for the talk and joining us here!
That just opens up another problem, you can have it reprogrammed on you by a hacker too. Perhaps from a closer range but the risk is there.
Radio communications are still black magic. You really need an EE specializing in radio if you want to get these things to work really well.
Implant a Flipper Zero…no longer a one-trick pony.
God, that reminds me of the time L0pht Anonym shoved an entire wifi router with onboard storage and a wireless charging interface into her arm.
Err, I meant Lepht Anonym. I got them confused with L0pht Heavy Industries.
I’m interested in the race between implant rejection and technological obsolescence, but not interested enough to run it in my own body.
Yes to play with that you’d have to have an obsession bordering on paraphilia.
Mine are still going strong 8 years later with no issues! I’ve also always had a use for them
I’ve had mine only four years. I was surprised, though I shouldn’t have been, one day when I stuck a magnet to it and it held.
That airlock type door for a work environment is pretty cool
It’s just a nicer looking version of the no-tailgating gate, isn’t it? It’s designed to make us feel slightly less like worker meat units.
Makes me want to start looking for an additional implant. Perhaps RFID with LED.
When burning lasers are within our capacity, sign me up.
After decades of study, self discipline and meditation I have achieved the power of spontaneous pyro-flatulation!
Very impressive work! Under “disadvantages”, I believe many implants may not be compatible with an MRI (magnetic resonance imaging). So, you could have x-rays and CAT scans but not MRIs done. I’m curious if you have information about this.
