I got one of these implanted in my wrist around ten years ago. AMA?

Does it use active RFID, or passive? If the former, when does the battery die? If the latter, is it possible for someone to burn you from inside by emitting the right microwave frequency with enough power?

  Passive. Not sure but it sits right under some thin skin so if they have a powerful enough microwave beam on that location it'd probably burn me equally from both sides.

For what use? How does the implanting procedure work? What about maintenance and replacement

  My friend owned a piercing shop and put one in himself which he used with his front door lock (plus a pass code).I was interested in RFID so I asked him to give me one. No maintenance. I don't even use it anymore so not sure it still works tbh. Another friend of mine had hers removed it wasn't a big deal her GP did it. Implant procedure at the time was a large needle through a pinched flap of skin then another tool which held the chip (it looks like a grain of rice) is pushed into the hole. The person then pushed it around through the skin to position it and you get a bandaid.

    In pets, the chips are just injected straight out of a large diameter needle into an area with loose skin (e.g. neck scruff). Millions and millions of pets have them.

      It's probably the process for humans now too. Mine was quite a while ago. I know friends who have had implant birth control just had the needle.

Does it have a cryptographic handshake or it outputs its secret for anybody with a scanner?
- sanswork 10y ago
  It broadcasts its ID to anyone with a scanner. I wouldn't call it a secret though.

RFID chips get obsolete. Eg original Mifire chip is considered insecure and should be replaced. Do you know which chip you have in? I saw the related Mythbusters episode and they mention it not easy to remove the chip after some years.

  Mine was never secure it just broadcasts an ID there is no key signing or anything. My friend had hers removed after closer to five years. GP used a scalpel to make a small cut and pulled it out. The process seems to be the same for women who get Implanon.
