Would you mind sharing your reasons for getting a magnetic implant? According the the wiki article, it's mainly used for "feeling" magnetic fields?
> You can't change the data on it, so if you get skimmed you need a new implant.
If it's basically an NFC tag, can't you make it read-write? Or is this potentially doing something more than that?
Also, how did you get the magnet implanted? Despite having no use for it myself, I still kinda want one.
It's impossible for an implant to be 0 risk.
Removal is more complicated than implanting.
You can't change the data on it, so if you get skimmed you need a new implant.
However if it is re-writable (some are) you'll need to know someone/buy expensive specialized hardware.
I say all the above as someone with a magnet implant in my finger for the past 6 years. I still love having done it. But for practical uses like payment systems in an implant sounds like a horrible idea. (https://en.wikipedia.org/wiki/Magnetic_implant)
