Has anyone taken a look at this Portal hardware wallet? Supposedly, it's built specifically for mobile devices. It looks pretty cool, and interacts with supported software wallets via NFC, but there's not a lot of detailed information on their website. Just some ambiguous descriptions of how it works, and other sales language. At $95, it's one of cheaper wallets on the market. If anyone has more information about it, or even just rumors, I'd be interested in hearing about it.
