The Coinfinity Card Wallet is a unique cold storage solution produced in Austria. This Coinfinity Card Wallet review will explore what it is and whether you should use it to store your bitcoin.
What is the Card Wallet?
The Card Wallet is a cold storage device developed by Bitcoin broker Coinfinity and the Austrian State Printing House. It allows users to safely store bitcoin (BTC) in a tamper-proof card, long term. 
Unlike online wallets that can get hacked, the Card Wallet is offline, thereby, protecting users’ digital assets from online attacks. Moreover, it’s easier to use than most hardware wallets which typically require technical knowledge to set up, and regular updates. 
The Card Wallet is available for purchase on its website or at Bitcoin broker Coinfinity’s physical office in Graz, Austria. The wallet’s creators have developed two separate wallets for bitcoin, retailing at € 39,90.
Keep in mind that the Card Wallet is for long-term storage. Therefore, it’s not ideal for the regular use of crypto assets. Although the Card wallet looks like a debit or credit card, you cannot use it at a point-of-sale terminal because it doesn’t have a magnetic stripe or chip.
How Does the Card Wallet Work?

 
Upon receiving the Card Wallet, you’ll notice that the wallet’s address is printed on the card’s surface. You can use this address to send BTC from a bitcoin exchange or another wallet to the Coinfinity Card Wallet. 
The private key is printed on the back of the card but sealed for security purposes. Don’t remove the seal since the private key enables you to unlock your coins should you ever need to transfer or sell them. If you leave it exposed, someone else could use it to steal your cryptocurrency.
A step-by-step process of transferring coins from a Card Wallet
Here’s how you can transfer your coins from a Coinfinity Card Wallet.

First, get instructions from your wallet app provider on how to empty private keys using the sweep function.
Once you have the guide, go to a safe place where you can transfer the coins from the Card wallet to an online wallet app. For instance, avoid places with cameras that could pick up your wallet’s private key. Also, use a secure and virus-free device.
Open the wallet app and initiate the private key import.
Scratch off the seal to view the Card Wallet’s private key.
Scan the QR code to import your private key. The wallet will activate the sweep function. If this doesn’t happen, start it manually.
If you can, set a high transaction fee so that your transaction can be confirmed as quickly as possible.
Reseal the private key with a Chainlock Visual Cover or opaque tape. Don’t forget to back it up before resealing.
Check the wallet app for the successful transfer of your coins. If your assets are in the wallet app, it means your Card Wallet is empty. Additionally, it indicates that your coins are now under a different public key (wallet address). Nonetheless, the private key remains the same.

Stay Safe
You must not use the Card Wallet after private key importation because its offline security will be lost. As a result, you’ll need a new Card Wallet for long-term storage. However, you can maintain the offline security of the Card Wallet by using the provider’s coin transfer service.
Card Wallet’s security experts import the private key on an air-gapped offline computer, maintaining the offline security of the Card Wallet. You can contact Card Wallet’s customer support to request this service.
How Does Card Wallet Keep Your Funds Secure?
The Card Wallet’s developers use Secure Entropy Technology (SET) to randomly generate private keys. The wallets are also manufactured in an isolated offline system in a highly secure room of the Austrian State Printing House.
The cards’ private keys are sealed before leaving the production machine and erased. Therefore, the workers inside the room never see the private keys, ensuring privacy and security for Card Wallet users. 
Should You Use the Coinfinity Card Wallet?

Yes.
Card Wallet is affordable and maintains a high level of security thanks to the SET method that the manufacturers use to generate private keys. 
The Austrian State Printing House has more than 200 years of experience producing security and identity documents with exceptional security standards.  This guarantees the Card Wallet users nothing but the best security.
Moreover, the Card Wallet is easy to use since it doesn’t require a technical setup process or any setup at all. The private key importation procedure is also pretty straightforward, and anyone can do it. To get your hands on a Card Wallet, click here .
