An encrypted NFC or Bluetooth bracelet, one sold with or separately to a phone would be nice. Pings it every so often. If it can't find it, automatically self locks. If it can't find for for X number of days and a password hasn't been entered in that time then it wipes || locks the phone.

Should be significantly more secure than Mifare though. Ideally something like a contactless OpenGPG card or similar.

Recently I searched for passive NFC ICs that'd be suitable for implementing that, but came up empty. Usecase was exactly that: A NFC device located at about the wrist. My laptop has a NFC reader at just the right place of the handrest to read it. And I'd probably transplant a NFC reader into my desktop computer's keyboard for the same purpose.

But first I'd need that NFC thingy.

Just had an idea, maybe not the wrist for mobile devices, maybe a ring that is always on the hand that is on the back of the phone. I don't know, but I can't help but think of how things can be more secure and that there is a market for those with security in mind.

Just found this also in my search while typing this comment.

Looks like it might be open source as well?

https://github.com/mclear/NFC_Ring_Control

Might be something to keep check on, it supposedly doesn't release until mid 2017.

EDIT: Just thought about if this is open source, anyone could possibly tie it in with automation apps such as Tasker and really do neat stuff.

I don't like rings (you put on your fingers). But that's just a personal preference. I'd be okay with wristbands though. Yes, the proximity to smartphone NFC readers would be a benefit of a ring.
