Secure Elements: Harnessing A Force of Nature

Yes! Couldn't agree more, a couple of other innovating features we have also developed to counter side-channel and supply chain attacks are a Web Authentication process for device genuinely and an anti-tamper self-destruct mechanism.

Thanks for your comment. We agree that an air-gapped computer can look less conspicuous to prying eyes than a specialized hardware wallet. However, since it's impossible to gauge exactly how much protection this gives individuals, it's somewhat out of the scope of this article, which is concerned with hardware security in worst-case scenarios.
