Card Wallet Review (2020) | Coinfinity’s COLDEST Version Of A Hardware Wallet!
In this Card Wallet Review, I am going to dive into why this wallet if built for the coldest of cold who like to HODL!
Outside of exchanges, few cryptocurrency markets are as thriving as safekeeping. At this stage in Bitcoin’s life expectancy, trading crypto as well as keeping crypto appear to be the most prominent use situations for crypto –– in that order. Consequently, a flourishing aftermarket for crypto storage services has sprung up, both custodial as well as non-custodial, hot and cold, on the internet as well as offline.
Card Wallet from Coinfinity is the most recent product to go into the fray, offering a protected method for keeping BTC as well as ETH offline.
As the risks of keeping funds on the internet in custodial purses as well as exchanges have been highlighted with a wide variety of hacks as well as departure frauds, the freezer company has grown. From hardware purses looking like elegant thumb drives to gadgets disguised as calculators as well as charge card, the variety of methods to self-custody digital possessions seems unlimited.
So, What Is Card Wallet?
The just named Card Wallet by Coinfinity does precisely what it sounds like. On the surface, this plastic card appears like an incredibly low-tech method to store bitcoin core or ether, however its unprepossessing exterior is misleading. Peer a little closer at the credit scores card-shaped wallet as well as you’ll discover some fascinating details. There are all type of anti-counterfeiting steps at play on the Card Wallet’s service, including microprinting as well as constant color gradient methods, providing it a look much more similar to money.
The banknote-based style makes sense once you discover that Coinfinity –– Austria’s first Bitcoin business — developed this device in conjunction with the Austrian State Printing House. They’re best known for printing passports, a skill they’ve refined over the course of 200 years, and thus know a thing or two about anti-counterfeiting. The notion of forgery sounds strange in a crypto context.
After all, bitcoins are impossible to falsify. The reason why the Austrian State Printing House has gone to town on the anti-forgery techniques they’ve used is to prevent fake cards from entering circulation and to provide guarantees that the private key, which was generated offline, remains offline. The private key for the cryptocurrency address printed on the card is concealed beneath a hologram on the back. It’s accompanied by a warning not to scratch this area –– not even a little, just to test it –– as to do so would be to risk the security of your funds.
The Card Wallet is basically a modern version of the Casascius physical bitcoins that have become collector’s items today. The code printed beneath the Card Wallet’s seal can be thought of as Schrödingers key: until the moment it is observed through scratching off the protective covering, it effectively doesn’t exist. The manufacturer has no record of it.
As a result, you can send funds to the address printed on the front of the card, but you can’t retrieve them until you reveal that seal, and doing so will essentially penalize you to the tune of the $67 the Card Wallet retails for. Think of it as an extremely high BTC network fee, and use it as an incentive not to dip into the funds stored on the card, save for an emergency.
Of course, technically nothing is stored on the card: it simply holds the secret code needed to send the bitcoin from the address in which it is currently locked on the BTC network to a new address on the network. To all intents and purposes, though, Card Wallet might as well physically hold those coins, since without it to hand, you’ll never be able to move those coins again.
How Is Card Wallet Different Than A Normal Hardware Wallet Like Trezor Or Ledger?
Unlike a hardware wallet, there’s nothing to power up or plug in here, but that doesn’t mean that testing the Card Wallet is an entirely analog experience. There is, after all, the QR code printed on the wallet, which, when scanned, reads the BTC address printed along the center. In testing, I scan the code using the Bitcoin.com Wallet and am prompted to select the amount of BTC I wish to send.
When I drag the slider, the funds are released and that’s it: the first satoshis prepare to wing their way to my Card Wallet. When the time comes to move or sell that bitcoin, I will remove the security seal and import the private key that’s revealed underneath into a noncustodial wallet such as Electrum.
In theory, you could continue to use the wallet address securely, even with the seal scratched off, provided you destroyed the exposed private key. There would be little advantage to doing so, however, and it makes sense to view the wallet as compromised once the key has been revealed.
Is The Card Wallet Secure?
On the reverse of the card, there’s another QR code that can be scanned, marked Chainlockcode (CLC). This requires installation of a dedicated mobile app, which will display the balance of the card –– and of any other Card Wallets you wish to integrate into it –– allowing you to manage all your cards within one app without revealing their private keys.
Most people are unlikely to need this, since typing the wallet address into a block explorer achieves the same result, but if you’re a serial Card Wallet collector, it might prove useful While Coinfinity doesn’t support BCH at this time, bitcoin cash holders have the option of generating their own paper wallets, which can be printed at home.
Card Wallet: Final Verdict
This theoretically provides the same security guarantees, and with the wallet folded and sealed correctly, it is effectively tamper-proof, albeit without the same allure as Card Wallet’s impressive shiny hologram. Cold storing cryptocurrency isn’t about showing off, however, and the winning wallet is the one that keeps your funds the safest. Some bitcoiners will balk at paying $67, in the Card Wallet, for a cold storage solution they could roughly replicate at home for the cost of a sheet of printer paper.
Others will appreciate the imperviousness of the Coinfinity card, its convenient credit card shape, and its superior tamper-proof seal. As such, its value is really in the eyes of the beholder. For the same price you could pick up a basic hardware wallet, which will allow you to send, receive, and store a range of cryptocurrencies.
That said, there’s something magical about the seal on the Coinfinity that challenges you not to sully it, but rather to sporadically send funds to it, building up your nest egg over time.

BC VAULT vs KeepKey (2020) | How Important Is Multi-Sig, Really?
BC VAULT vs KeepKey! In this comparison, we are going to do a head-to-head of two of the most competitive and popular new cryptocurrency hardware wallets in this edition of the hardware wallet roundups.
I am going to dive into which of these hardware wallets is better and more secure. How big is your portfolio? Do you need mobile AND desktop support? Do you use any 3rd party wallets for integration? Do you need web-based access instead of a required download?
These are all questions you will need to consider when deciding which of these wallets will be best for you. At the end of the day, the coin support is one of the most important factors (besides security) when deciding which hardware wallet is best for you.
Ultimately, if it doesn’t support the coins you want to store offline, it won’t work for your particular situation. So keep that in mind as we dive into what I consider to be the most important factors when making such an important decision, such as choosing a cryptocurrency hardware wallet.
BC VAULT: Overview
Unlike most other popular cryptocurrency hardware wallets, like Ledger Nano X and Trezor Model T, you do not set up a recovery seed card before you initialize the device. In fact, there is a gyro sensor for you to randomly generate private keys by physically shaking the device (seriously).
You can also hold more than 2000 unique wallets within the web app, and can granularly set specific passwords for each one and setup multiple PIN’s to not only make it more secure, but also allows for an easy way to share the device and use Multi-Sig. In fact, this is the first device that natively allows you to use Multi-Sig on a per wallet basis and set multiple PIN’s.
This wallet does not use HD wallets, so each wallet has its own unique backup. This does make it more secure, however, if you lose or forget the global PIN and global password for the device, your funds are locked inside forever. They do have an encrypted QR code backup for each individual wallet, or you can create a backup on the included micro SD card that comes in the box.
BC VAULT: Security
The storage is reliable. The BC Vault’s private keys have complete encryption and they are stored in the FRAM device. The FRAM is fully tamper-resistant and thanks to the reversible USB 3.0 Type-C connector any damage occurring from mechanical error is fully prevented.
In addition to the secure FeRAM that is securely encrypted, and the large display which is useful when confirming transactions, you have peace of mind not having to worry about anyone locating or using a recovery seed phrase to render your funds useless.
You can also import any private keys you have elsewhere via the SD card as well, so you can easily interchange private keys from other wallets if you have them in the correct format.
BC VAULT: User Experience (UX)
This wallet has some pretty unique features I will admit, and it’s pretty refreshing. For example, you can use multiple cryptocurrencies at once. There are no “apps” you need to install or fear or worry of running out of space that most wallets have when upgrading the firmware.
Additionally, the amount of coins and wallets that can be used/stored simultaneously is astounding. As mentioned above, you can have up to 2000 unique wallets and can interchange multiple cryptos in multiple wallets.
BC VAULT: Coin Support
This is usually one of the most important factors when deciding on a hardware wallet (with the exception of security). If the wallet doesn’t currently support the coins you need to store offline, you can’t really take it too seriously as a deciding factor for purchase. Regardless of whether or not they claim to add more coins in the future.
Needless to say, they have some unique choices for coin support HERE.
KeepKey: Overview
KeepKey has been one of my absolute favorite hardware wallets to use in 2019. I was asked to test and report back issues with the ShapeShift beta that was a complete overhaul and utilized the KeepKey as it’s cornerstone of promoting keeping possession of your private keys under your control while you conduct trades, which has never been done before.
It was an ambitious goal, but they pulled it off in spades, and as a result it resulted in one of the best user experiences while using a hardware wallet I’ve ever encountered. It was quick, safe, and makes it easier than ever to manage your assets, portfolio, and trades all while keeping all your keys on a hardware wallet and never forfeiting custody. This is truly a game-changer and will pave the way for future hardware wallets moving into the next decade.
Let’s find out why below!
KeepKey: Security
KeepKey has a true random number generator (TRNG) for it’s PIN interface for extra physical security. In addition to offline storage, KeepKey’s PIN code and number randomization makes sure that
1) Your wallet is secure from physical theft.
2) That a hacker couldn’t steal bitcoins from your wallet with malware.
KeepKey is an HD wallet, meaning your entire wallet can be backed up with the 12 words generated on setup. 12 words is the default setting, although KeepKey supports seed lengths of 18 and 24.
The seed is generated using entropy from both the device itself and the computer used for setup. The seed is generated offline on the KeepKey and displayed on the device’s screen. The device’s offline screen makes sure the seed is never displayed on an internet-connected device.
KeepKey: User Experience (UX)
w,This is a complete overhaul that includes all of their services including: Instant Trades, Real-Time Market Data via CoinCap, In-App Crypto Purchases, and KeepKey Integration. That last part is of particular interest to me because I’ve wanted to find a way to execute purchases and trades while having my KeepKey connected, while ensuring that my private keys are protected throughout the entire process.
This is a very important detail, especially if you want to make purchases online with that extra protection and also ensure that my private keys are never compromised in a trade. This truly is the ultimate non-custodial hardware wallet solution. Here’s a few screenshots and user flows based on my experience using this web app.
KeepKey: Coin Support
Natively, this wallet in the current form supports over 40 assets with more on the way! Here is a current list of assets that are supported right now. Now let’s get into the nitty-gritty. For years, KeepKey only supported: Bitcoin, Litecoin, Ethereum, Namecoin, Dogecoin, and Dash. For a hardware wallet that needs to compete in this market place, that needed a serious upgrade.
Luckily, they have been making some AMAZING changes and not only added a ton of ERC-20 Support, but more importantly, they are revamping their entire platform to have one fluid, seamless application that integrates all of their core services (See my previous post for details on this). This is extremely powerful, and a decision that I believe will catapult them ahead of the competition. They are currently in a closed beta, and it is expected that they will be releasing this later in 2019. Stay tuned for news on this.
Some of the notable coins that have been added are:
-Chainlink (LINK)
-DigixDAO (DGD)
-Binance Coin (BNB)
-Dai (DAI)
-Maker (MKR)
-TrueUSD (TUSD)
BC VAULT vs KeepKey: Conclusion
Honestly, this is a tough one. My experience has been extremely pleasant when using both of these hardware wallets and I use them both for different coins and different use cases. Having said that, I enjoy the trading and portfolio experience on the KeepKey better.
The BC Vault is a VERY unique and robust wallet, especially if you want to secure share this hardware wallet with multiple people and want to use multi-sig to have shared wallets with multiple “voters” required in order to spend a transaction.
As of the time of this writing, you can can get a Keepkey for under $50 during this holiday season special and comes in multiple colors, so you will get a high quality device that is easy to use and uniquely allows you to trade your assets without ever releasing custody of your private keys.
This is a VERY big deal, and has not been done yet on any other hardware wallet. Although, Shapeshift has recently added some limited support for Trezor and Ledger Nano S.
All this to say, if you want a robust “vault” that is very intricate and allows for multiple users to use it safely, go with the BC VAULT. If you like to trade and want a very user friendly way to manage your portfolio, you can’t go wrong with the KeepKey.
BC VAULT vs Keepkey! What do you think? Would you choose the BC VAULT over the D’CENT Wallet? Let us know down below in the comments!
