That also makes it less secure and exponentially easier to brute force compared to a passphrase of let's say 8 random words.
Not if it is backed by strong tamper-resistant hardware security which has brute force prevention mechanisms. We use smartcards that have been battle-tested in the banking industry for more than 50 years. Regardless, you can still use a passphrase with the product if you value that more for the security of your assets even with Cypherock X1.
I knew you would say that, and it's, of course, in your best interest to sell as many as possible. Buyers would obviously want to buy only one and have it work for a lifetime.
Not necessarily. Also, the same could be argued for any other hardware wallet.
Does that mean that the recovered seed in that case pops up on the screen of your cell-phone or is shown in some native software environment by Cypherock?
This is more relevant in the case if ever Cypherock goes out of business. We will have our own open-source IOS and Android apps as well for this. But the seed phrase can be recovered directly on the smartphone without our assistance directly from the cards when you enter the correct PIN if set. Although it is definitely not recommended for your hardware wallet seed phrases and should be used only if Cypherock ever goes out of business.
