Tamahagane Bitcoin Cards are an easy and safe way to store Bitcoin offline and they make a beautiful gift. These attractive metal cards can survive fire, flood, and natural disasters, will not fade or break down, and allow any amount of value to be physically carried and stored easily.

Until now Bitcoin has not been an accessible gift. But Tamahagane Bitcoin Cards are easy to give or to receive and store. They are metal cards with permanent laser engraving. They contain a secret phrase that’s hidden by a secure, tamper-evident covering. There are no passwords to lose, the card itself is all you need.

Digital gold

Bitcoin is a new decentralized monetary asset, akin to gold. It combines the scarce, money-like nature of gold with the digital transferability of modern currency. It has gone through three major cycles of adoption so far, each cycle ending with a floor value that is 100x the previous cycle.

As it gains rapidly maturing support within the traditional financial system it will continue to become a more accessible investment.

A physical offline Bitcoin wallet

The beautiful engraving includes a public address that can be used to add Bitcoin to the card, allowing it to function as secure cold storage. The secret phrase can be uncovered when it’s needed to transfer the Bitcoin funds.

How does it work and why is it secure?

A Tamahagane Bitcoin card is a "cold storage" Bitcoin wallet. The secret phrase which provides access to the wallet is engraved on it and hidden by a tamper-evident covering. It also has a public Bitcoin address to receive funds.

The wallet is generated on a system that's completely and permanently offline, never connected to the Internet. The seed phrase is then engraved on the card and immediately concealed by the tamper-evident covering, and the system is immediately reset with all data securely wiped each time.

The tamper-evident sticker that covers the secret phrase cannot be removed and replaced without visible evidence, and its unique code verifies that it has not been replaced by a new one. This guarantees that the secret phrase has not been seen by anyone except the recipient.
