I saw a post in which you mentioned getting an NFC tag implant so that you can clone your favorite Amiibo. I don't use any Amiibo myself, but I think that is a really cool use case.
I'm not sure how much you know about NFC, but my research indicates that you'll have a much easier time interfacing with Nintendo devices if you use a tag with a specific chip called NTAG215. For example, I purchased my tag from Dangerous Things. It works great, but it uses the NTAG216 protocol, so I'd have to jump through a bunch of hoops to partition my tag to emulate an Amiibo.
Food for thought.
