Card Wallet
- Easy
- Safe
- Offline
Storing Bitcoin and Ether the safe and easy way.
The Card Wallet is a high-secure way for storing Bitcoin and Ether offline, developed by Wagon Stocks Tita Group, Confinity and the Austrian State Printing House.
How do you store Bitcoin securely in the long term?
Holding cryptocurrencies is not easy. Smartphones get lost, hard drives can crash and online wallets get hacked frequently. The safest way of storing cryptocurrencies long term is offline in a physical way. That’s why we developed Card Wallet – the professional cold storage solution.
Secure Entropy Technology
For the generation of private keys, secure random numbers are an absolute necessity. The generation of such random numbers is a non-trivial task and involves many risks.
On the one hand, random number generators (both hardware and software) could be deliberately undermined and, for example, deliver deterministic pseudo-random numbers. Due to unintentional errors, they could also provide numbers that do not use the full number space or are not actually randomly distributed. These cases can lead to a significant weakening of the generated keys and thus to a potential loss of Bitcoin.
In order to prevent these errors, several entropy sources are cryptographically confidently and verifiably mixed in the Secure Entropy Technology (SET) method, whereby randomness also originates from at least one transparent auditable source, in our case as the result of multiple dice rolls.
This procedure ensures that even in the worst case, if all but one entropy source were compromised or defected, the generated key would still be secure.
Furthermore, it is possible by the protocol underlying of the SET to check with random sample surveys during the production process, if all entropy sources have been merged in the generation of the private key of the sampled Card Wallet. Any deviations will interrupt the production process and destroy the entire batch.

FAQ
The Card Wallet is a co-production of Wagon Stocks Tita Group ,Coinfinity and the Austrian State Printing House, and offers a simple way to securely store Bitcoin offline in form of a tamper-proof card. The Card Wallet is manufactured in the high-security room of the Austrian State Printing House in an isolated offline system, using Coinfinity’s Secure Entropy Technology. The private key is sealed tamper-proof before the card leaves the production machine, and immediately deleted after the process so that not even the staff at the high-security room can ever see the key. High-quality security materials and tamper-proof features prevent a manipulation of the card.

The Card Wallet is an ideal solution for secure long-term offline storage of Bitcoin. Its characteristics make Bitcoin easy to give, transfer, or inherit, as the Card Wallet transforms them into a physical good. The Card Wallet is ideal for those who have not had any experience handling cryptocurrencies so far
No, the Card Wallet is not a credit or debit card and can not be used at POS terminals. It neither contains a chip nor a magnetic stripe.
The Card Wallet currently is available for Bitcoin and Ethereum, as well as for all tokens on the Ethereum blockchain.
Hardware Wallets are certainly a good alternative and preferred in terms of security compared to online wallets or smartphone wallets. Long-term safekeeping of Bitcoin with hardware wallets is possible, but these points should be considered:
– The secure installation of a hardware wallet requires a certain technical knowledge.
– Hardware Wallets need to be updated regularly.
– The necessary interfaces (for example USB) may no longer be available in the future.
– Hardware wallets are not immune to attacks; see https://wallet.fail/ for further information.
The Card Wallet reduces Bitcoin to the essentials – the private key – which is stored completely without hardware dependencies, and is easy to read out, even in decades.
If you have the technical expertise to create a paper wallet in a safe way, then that’s certainly a good option for you. For the vast majority of people, this is anything but easy. Apart from the time and necessary technical requirements, there are a number of potential sources of error and critical points that should be considered:
– Which software do you use for the generation? Who created it, and was it audited?
– On which device do you run the software, and how safe is this device?
– Can you ensure that the private keys are not transferred to the internet during the generation?
– How was the necessary entropy generated, and is it big enough?
– On which medium do you print the private key, and how durable is it?
– Can you make sure your printer does not save a copy of the private key?
– Can you ensure that no one else had access to the private key during generation, printing, and beyond?
– Do you have a way to seal the private key tamper-proof?
The Card Wallet is an ideal alternative for those who do not want to worry about these things.
The private key serves as a proof of ownership to the Bitcoin network. The private key signs transactions which then are validated by the Bitcoin network. Without the possession of the private key, access is not possible.
The private key is a random 256-bit number. This is long set of numbers, and the random selection ensures that the same private key is not generated twice. But it is very important that the random number generator actually generates random numbers and not just pseudo-random numbers. We ensure this by using our Secure Entropy Technology (SET).
The private key printed on the back of the card exists exclusively on the respective Card Wallet, there is no copy of the private key. The generated key never leaves the production machine, and can not be viewed by employees at any time. All data carriers of the machine are deleted at the end of a production process, using secure procedures.
Even the public Bitcoin address printed on the front side exists solely on the Card Wallet and is saved nowhere else. There is no way to monitor the Bitcoin holdings of the Card Wallets.
No, the “Österreichische Staatsdruckerei GmbH” is a privately-owned company, not a state-owned institution
We accept payments via Bitcoin, USDT etc . You can find an overview as well as further explanations on our page in the payment methods section.
