Push hard on my skin, and you’ll find that the source is two lumps of glass, metal, and plastic embedded in my right hand: a years-old magnet in the ring finger and a newer NFC chip in my thumb webbing. Before getting the magnet, I read paeans to the coming cyborg revolution. After putting it in, I had people tell me my hand would fall off. Since getting the NFC chip in June, I’ve read that I’m carrying the Mark of the Beast and found instructions for how to disable it with a taser. Well, I come from the future, and I’m here to tell you: transcending the limits of the flesh can be downright dull.

The woman writing above can sense/feel local magnetic activity – whether it is microwave ovens, hard drives, regular metal or other magnets. It has added another dimension to her senses, and likes it – although her friend who had the same magnet inserted is now over it.

And her NFC chip – it is pretty much useless at present, not enough uses for it. And situations where she would love to use it, like replacing her employer’s security keycard, aren’t an option because it is non-standard. Still it is interesting that she purchased the chip and installation kit online and inserted it herself.

You can guarantee one day there will be an Apple of implanted chips that will provide you with secure identification that can’t easily be stolen from you. Just not yet (except for that Spanish nightclub a decade ago!)
