Cloning a Verichip Yourself

Posted by Xavier Ashe on January 2, 2007


I used a relatively sophisticated piece of electronics to clone a
Verichip.
This made things trivially easy. Even though I had never seen a
Verichip before in my life, I just had to write a hundred lines of code;
but because I used my proxmarkii, I've heard claims that it is impossible
to talk to a Verichip without expensive equipment.

Also, I embarrassed myself in front of a documentary crew when I couldn't
clone the Verichip that their presenter had had implanted. (He was a
fairly big guy, and the chip was very deep beneath his skin, so I didn't
have enough read range to do it with my proxmarkii. We tried shoving
the antenna into his arm, but I think we just pushed the chip deeper. A
proxmark3—which can read them at the correct operating frequency of
134 kHz, instead of 125 kHz—would have worked fine, and in fact I
had brought two of them; but I destroyed both, through my own stupidity,
before I got a chance to do the demo. If you build a proxmark3, then
don't forget to populate D10/D11.)

I therefore wanted an inexpensive cloner, with decent read range and
a simple user interface. It should be easy to build, and it should
not require a PC to operate. This will make it easy for you to clone
a Verichip yourself, even if you don't have a lot of money, or any
knowledge of electronics. The device will also be simpler to use, and
have fewer parts to fail; if more journalists have chips implanted, then
this reduces the chance that I will screw up the demo for them as well.

This device can read and replay a Verichip's ID. If you can get the
antenna close to your victim's shoulder, then your circuit board
is electrically indistinguishable from their implanted chip forever
after. Full schematics and documentation are given below.

Details on Cq.cx.  Good project to do for the new year.
