Game developer Zoe Quinn recently implanted an NFC chip in the space between her thumb and index finger. Appropriately enough, she's since programmed the chip to send a link to her Humble Bundle page for Deus Ex, a popular shooter game about cyborgs. So, if you bump into her, you can tap your phone against the base of her thumb and get a free video game about human/robot hybrids. Here's a video of the operation, which starts at about the four-minute mark. It's not for the squeamish, and it certainly doesn't help that she had to inject it herself with a giant needle.
This isn't Zoe's first stop on the road to cyborgdom either. She's already implanted a tiny magnet in the tip of her finger, enabling her to feel nearby magnetic fields of all sorts. That's notably less practical than an NFC chip, but certainly an interesting exploration in our relationship with machines. Apparently both are too small to screw with airport security, MRIs, or debit cards. The two implants also don't interfere with one another. As for the pain level of getting the implant, Zoe says it barely hurt compared to the magnet.
The NFC chip in question is an NXP NTAG216 which offers 888 bytes of data transmission; easily enough to issue commands and share links on smartphones, though she's still exploring the possibilities. For the immediate future, she aims to make a game that plays with her implant. Here's a quick look at what she can do now.
Zoe's got a background in body modification, realized this whole thing was crazy, and went ahead and did it anyway. When asked if other should try this, she says "DON'T BE CRAZY. ... I am a dumb, dumb person." The funny thing is, Zoe's not the first person to get this sort of implant, and likely not the last.
A few years down the line, procedures and products for these operations may very well be ironed out and regulated. In that hypothetical future, would you be interested in getting an NFC implant? Why or why not? Would you have the cojones to inject one into yourself if it meant you could get one now? What would you use it for?
