Opened this thread and was about reading on but, when I saw how long it was, I jumped to the summary at the bottom and then back to read up from the beginning. To be frank, it was an interesting read and review as, most of my curiosity was answered along the lines just as they developed.
Like Charles-Tim, one of my concerns was
This air-gapped operation greatly reduces the risk of attacks from malware or from hacking, as the wallet never exposes sensitive information.
According to what I saw about it online, before the seed phrase backup is done on the cards, it requires Internet connection. Is it true? For the seed phrase backup, it is displayed on the phone. The phone that can mistakenly be online or that people might not on the airplane mode while setting it up.
Having it in a mobile device that would have internet on it during the setup. I guess the right idea here would be, turning the internet data service off or WiFi before going through the pairing the cards to the wallet that is, right?
Another of my concerns was the NFC technology as mentioned; haven’t seen some videos on social media where NFC enabled devices were just brought close to card holders bags and possibly their pockets and have transactions confirmed raised concerns for me but,
The fact that the transaction would be originated in the app and only signed with the card thereafter before it’s finally broadcasted gives me some great comfort.
Given that the card is made of high quality plastic and labeled to be almost indestructible, how would it do with fire though, what’s the melting point for the card if you’ve got any idea and would heat affects its internal components like, the chips even without the card melting?
In all, the over all design looks good and the black card is sleek, I like it!
