Nice read. One thing I would definitely want to have in my hand is a hardware cryptocurrency wallet, but that'll require power source and some interaction interface. However, existing microchip implants can be used to increase security level for some apps/wallets. For example, you may have an app that require not only password, but also your NFC tag to read (concat both, for example). If hackers steal your password, they won't be able to login without reading NFC, and vice versa, if your NFC content is leaked, they still need password.

All the available chips are in essence low-cost and thus low-security NFC/RFID tags. Depending on application it means that either the tag is trivially cloneable or is trivially cloneable by any reader that is able to read it (ie. the authentication protocols are typically "backwards" and the reader authenticates to the tag, not the other way around which would actually make sense). Probably only massively deployed NFC protocol which actually somewhat makes sense security-wise is EMV NFC (and that is in fact only straightforward mapping of how contact EMV cards work into NFC and it's limitations).

>but that'll require power source and some interaction interface. Oh, I dunno - here's an RFID transmitter which only uses 2 pins on an ATTiny, neither of which are power or ground: https://trmm.net/AVR_RFID https://trmm.net/AVR_RFID Okay, technically the power source is the external RFID reader and the interaction interface is hardcoded, but that would work fine for something like a crypto key.
