I bet Tweetious has a few of their cards.

This edition -photo below- was exclusively available through Kickstarter. Later on, -after fulfilling their Kickstarter rewards- they started selling those wallets through their site & Amazon. (+ added moar variations such ETH, USDT etc.) My Kickstarter reward was sent from Spain. https://www.kickstarter.com/projects/materialbitcoin/material-bitcoin/description https://www.talkimg.com/images/2024/01/10/sif7q.jpeg They've been around since at least 2022, but haven't seen anyone really talk about them.

It has sort of a metallic strip to cover the pk on the backside - I would not use it personally - do not know the maker or their key generation process.
there are many out there very similar to this as well. https://www.etsy.com/listing/1251032626/bitcoin-wallet-card-personalised-name? https://www.etsy.com/listing/1148605388/bitcoin-btc-wallet-card-aluminum-custom? I also have one of these https://seedhammer.com/ which allows me to create my own steel plates for single sig wallets or multisig wallets - 3 different plate sizes depending on needs. Title: Re: Material Bitcoin - a new cold card I have not seen before Post by: RickDeckard on January 10, 2024, 10:13:50 PM I remember this one and I am sure that @The Sceptical Chymist does[1] as well. I'll just highlight a quote of mine from the thread:
Apparently this company - based in Spain - started in 2019 and got their funding from Kickstarter[1] and "309 backers pledged €36,575 to help bring this project to life". In the comments[2] section of KS they keep referring that they have no way of knowing the private keys that are engraved and they also say that their private key (the one that supposedly "is generated by a state-of-the-art, open source, offline, cryptographic engine") is generated by Electrum. Even if they were the most honest company in the world, I wouldn't believe that there can't be a malicious actor, or even worse, that they do something manually during the process that could put in jeopardy the safety of their wallets. They reassure their clients by saying that their "autonomous" process has been certified by Lambda Telematics[3] but I don't see quite well how this certification could have been issued. Perhaps Lambda Telematics wrote the code that their "robots" use to manufacture their cards? If so, what stops someone to hide a malicious entry in the numerous lines of code so that every private key is sent to some random address without anyone knowing? What is even more weird - How come that with just ~40.000€ - they were able to build a production line (I suppose that there is one) that engraves the plates and packs them in a security bag with no Human intervention when 70% of the funding went into developing the product[1]?

Other than that I wouldn't feel much comfortable using it to store anything of value.
