+ Resistant to fire, water, bugs, shock wave and rust (better than a piece of paper)

My reply to this would be that you can have multiple pieces of paper / multiple backups for just pennies, so if one backup location burns down, you have another backup elsewhere. That's good practice anyway (e.g. in a flood, that metal plate can easily be flushed out of your home), but too expensive to do with expensive metal cards.

+ Easy to use with NFC (no more metal letters)

Now, here it gets tricky. How do I write my seed phrase to this device, that is supposed to be super offline and super safe, whilst at the same time needing to use my phone for the process? I will never ever type my seed phrase into a phone app, so what to do?
On paper, I can write with a pen, and even a USB thumb drive is writeable by a live Tails OS. Would I need an external NFC transceiver for my offline PC? Does such thing exist and if so, is that open-source in its hardware and software / drivers?

Unfortunately, offline.

Hi

I agree with you, better to have more than one card. Depends of how much cryptocurrency you have, $ 49 by card make sense.

For now our app is only for iOS and Android, but soon we will have a version for desktop. So you can use any NFC reader/writer to connect on your desktop.

And yes, you can do all operations offline, airplane mode for example (we recommend this on app)

You need to decide what is better, leave your current seed only on paper or type the seed on CryptoPlatz App to save encrypted on the card, offline.
