  • Aimee Mullins gave an interesting TED talk a few years back, in which she described her lower-leg prostheses as devices that had augmented her body rather than just provided more or less adequate replacements for her real legs. For "simple" body parts like lower legs, I reckon the field of prosthetics is sufficiently…
  • Hi Liza. To answer your questions - from my perspective anyway: Several reasons: Implants: * I keep losing my keys and access badges to the various places I patronize that use them, and I hate wearing watches, bracelets or jewelry (that I would lose also, no doubt). My NFC / RFID implants stay with me at all time, and…
  • An image being worth a thousand words, here's a video of me authenticating under Linux with my NFC implant (left hand) and my RFID implant (right hand): And here's another trick you can do with my scripts: use a cellphone as an external NFC reader to authenticate under Linux: It's a bit of a Rube Goldberg setup, and it's…
  • I wrote code to allow generic Linux login with any contactless card or tag that supplies a UID - that is, pretty much all of them. That includes low frequency RFID tags, provided your RFID reader is PC/SC-compatible. For instance, my Elatec TWN4 Multitech reads RFID and NFC tags, and I use it to log into my Linux box with…
  • A Proxmark is on by to-buy list. But with the xmas season idiocy in full swing, if I order now, I'll get it in January anyway. So I might as well wait a bit to order it. But yeah, right now the chip registers on the readers I need it to register on, so it'll do fine as it is for the time being.
  • Not sure. The German distributor I bought it from has this annoying habit of renaming the devices he sells with his own simpified naming scheme. But the specs say it supports 100,000 writes, so I'm guessing it can be rewritten, logically enough. I'm not really interested in writing to that one but I'll goof around with it.
  • I implanted a RFID implant today (EM4200, on the larger size). Indeed the range is excellent, even through my still-swollen hand. As a bonus, I've found a use for my TWN4 Multitech reader: while it's completely hopeless with my NFC implant, it works dandy reasonably well with the RFID one.
  • Yes, a LF chip is next on my list. I'm still trying to decide which model, for the sake of maximum compatibility with readers that are out there (EM4102 / 4200 probably), whether there are models that I can change the UID of - and without risking bricking it - and where to implant it so it's safe, convenient and leaves…
