Not this paper again. It can't be used for cryptographic usage and the title(which is the original title of the paper) is completely misleeading.

The device you're authenticating must have the secret you're authenticating with in it in a retrievable format. So it can't be used for e.g. disk encryption, etc, because the attacker can just get the secret from the device and decrypt.

All it can be used for is authentication, and for that they require a human security guard to ensure it's actually a human playing the authentication game. If you were to attach a computer, its likely it could impersonate you. So almost completely useless (except for getting people's hopes up).
