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.

n0nce has a point, people don't want to be online at all when they are dealing with their seed words.
Device with CryptoPlatz app needs to be online to download and install it, so desktop app is must have option for everyone.
Airplane mode but most people could make a mistake and just used app online.

Can you tell me what android version is oldest supported by your app?
Older phones might not be able to install app so that could be one more issue I faced before with other Android apps.

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?

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.

I need your help again from all of you. What do you think will be a good price to sell? Our plain is to sell for $ 100,00 But we would like to know your opinion.

If we change the Indiegogo campaign for example to $ 50,00 are you going to buy on Indiegogo today?

I don't know how much is production cost going to be to assemble Crypto Platz, and that is probably depending on location of country you are ordering all the source materials.
For Indiegogo campaign price of $50 would be much better, and it's comparable with stainless steel plates and some other cards that store seed words.
I am not sure if I would pre-order this card right now before I see some early testing reviews, but you could give reduced price and start spreading the word on twitter and social media.

Now we are giving 50% discount exclusive for Indiegogo campaign, CryptoPlatz Vault now is €49,00. The campaign will finish in less than 30 days.

Thank you for advices

I would have a good look at a few factors -
1. Costs - production, postage, website, wages, advertising and anything thing else - don’t forget anything !
2. Your DIRECT competitors prices
3. Future of the company and product - will you be producing version 2, limited editions etc
Have you produced a business plan? If not, do one - it may sound boring, but it will help.
Hope this helps and importantly, don’t sell yourself short

The password is optional, if you use, will be encrypted.

Am I correct in assuming that without the password, anyone that gets their hands on the metal card in question, can easily decrypt or rather access the information that's stored in it?

The question is also what is stored. Is it a plain text (words) or for example entropy (as seed words <-> entropy are exchangeable). But it would require an algorithm inside the application which would "understand" the seed words (verify checksum etc). And I suppose it would not support seeds other than BIP39, maybe would be even limited to English dictionary. Much simpler would be to store any text provided by user, without parsing it.

Hi

The CryptoPlatz App and Card (vault) accept any text (passwords, mnemonics, 12 words, 24 words, bip39...) in any language (English, French, Spanish, Portuguese, Chinese...).

If you use a password to encrypt, the text will be encypted with AES-256. Does not matter what text is it.

Yes, you are correct. This is a prototype in PVC. Because that we are on https://www.indiegogo.com/projects/cryptoplatz-card to manufactory in metal stainless.

I guess you could create some free campaign or beta testing for this prototype PVC cards, and if everything works fine you could probably collect funds easier on indiegogo.
Problem I have with stainless steel material over NFC chip is that it could block the antenna signal and not work in the real life.

I was looking at the differences. These comparisons between a software run device and a piece of metal is actually not relevant at all.

A metal really does not need to have encrypted. With a cleaver combination someone easily can hide some information which even if it ends up to the wrong guy still they can not get the idea of what was there.
In a metal sheet it's obviously does not make sense to have password.
Well nothing has forever warranty or guarantee
Open source of course nothing to do with a piece of metal.

I agree with you, but save encrypted it is a good feature. But, if somebody don't want to encrypt, he can save in plain text, like metal plate.

We have published our open source code on GitHub

Yes, but they can't have my coins if I have one or more strong passphrases on top of my paper or metal plate.
CryptoPlatz is encrypted, but if customer used weak password that it can be hacked and extracted by someone who knows how to do it.
I am not saying CryptoPlatzdon't have some advantages, but it's certainly not universally perfect solution.

I agree with you, it is important to have more than one backup of seed recovery phrase

When compare with metal plat, there are a lot of benefit, but the most important is you can save the passphrase encrypted with AES-256. So if anyone put the hands on the card, they can't read the passphrase.

After reading about the card i see it's only for storage and we can't use it to spend or deposit bitcoins. The main idea is to save a passphrase, mnemonic, or passwords. And it has a limit of 888 characters.

To access to the data we need the APP and the password, if we forget the password then all our data will be gone.

From my point of view it doesn't worth to spend money on a hardware to storage data with a password, there are a lot of ways to do that. Even we can use PGP to encrypt any data and then Decrypt it with a key.

I don't say the product is bad, it has some great features, but if i will have a crypto card i would use one that allows me to make payments.

Hi

Yes, you are right. The card is not to spend crypto, there is another options to this, like Coinbase Card and Binance Card.

CryptoPlatz Card it is to save you passphrase or mnemonic on a device more resistant than a piece of paper.

You can use PGP and others ways, you are right again. But CryptoPlatz App are focus on the end user, that need to keep his "seed passphrase" store safe, but don't have the skills to do this alone.

CryptoPlatz it is compatible with Trezor, Ledger, Exodus, TrustWallet and any other wallet that demand you to save the seed recovery phrase on a paper.

What makes it compatible with wallet or not?
In my opinion you just use NFC to transfer some data to the card (so you have NFC chip in/on the card) and as it could be any data, it has nothing to do with BIP39 compability.
And as I understand, the same application is needed to read from NFC chip and restore the content, right? That would be very very very risky. Now, on market we have in general Tile trackers and Apple AirTags. In the past there was also TrackR - one year ago they stopped supporting their product, removed apps from the mobile stores and suddenly all the products they sold during last years became a plastic junk.

Remember, our app will be open source on GitHub, so anyone can read and copy.

But more important, if you know the password used to encrypt the data (seed), you can decrypt using AES-256 algorithm.

So you don't need our app, it just exist just to be easy to use. Cheesy
