PIN can be remembered also which makes it exponentially better than seed or passphrase.
That also makes it less secure and exponentially easier to brute force compared to a passphrase of lets say 8 random words. Relying on your memory is also not recommended especially when a person gets older.
The idea is it is much easier to hide in plain site it than the 24 words which has higher pattern matching as seen recently. Additionally, with securing the seed phrases, the more obscure the setup is, the harder it is to make it inheritable.
No argument there.
Not required since you can buy another device, and it will function like the old device.
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.
Else, you can also recover back your seed phrase from the two cards with the help of an NFC-enabled smartphone.
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?
