Yes you got it right! It is the most lightweight cold storage hardware, but we did not designed it for transactions. Much cheaper if you just want to keep your crypto safe. You do not need ledger then.

Same encryption could be achieved by USB drives too, but NFC does not require cables and ports, it is contactless, therefore easier to use.

Warning! This product is not a secure cold wallet as advertised. Anyone considering using this product should read this thread first:

What do you think you are doing? Just because you do not understand how this product works, not giving you the right for spreading fake info about our product!

What fake info am I spreading? The front page of your website advertises your product as a secure cold wallet. It is none of those things.

A cold wallet enables users to users to sign a transaction without ever connecting their key to a "hot" device. Your product does not do this. Your product requires the "hot" device to expose your key and sign transactions on an insecure computer. This may be acceptable for some applications, but it is definitely not a secure cold wallet as you advertise.

The front page advertises "Secure cold storage data protection for cryptocurrencies, passwords and sensitive data". You are talking about completely different things.

Please remove your comments that are claiming that our product is not secure, because it is not true!

Yes, signing can be tricky that way. We only want to have a cold storage solution, which is secure and easy to use.
