One of the varieties of wallets for cryptocurrency is hardware wallet. They are not only virtual repositories for Bitcoins, but you can even feel them physically in your hands because they look like a flash drive where you store your crypto-tokens. In this case, the device for operating cryptocurrency assets must be purchased – they are not provided on a free basis, like online clients or desktop applications.

Hardware wallet: how it works

A hardware wallet is a kind of offline storage for securing your cryptocurrency security assets. Here, the Internet does not have access to your private keys and other confidential information, which excludes the possibility of hacking and stealing funds. In addition, the use of such wallets when connecting to hacked devices or devices that do not have the required level of protection is safe.

Most hardware wallets are equipped with screens. In addition to the fact that it is very convenient because the screen displays the actual information when working with the storage, it is also an additional security feature – it is easier to pass verification and monitor the state of your balance.

Below we will consider the most popular hardware cryptocurrency wallets.

Keep Key – one of the pioneers, equipped with a screen

This product entered the world market in 2015 and quickly gained a leading position, as well as the love of users. It is the second Bitcoin wallet, which is equipped with a screen for the convenience of working with cryptocurrency.

The rather impressive size of the display allows for maximum security for the media, while some of the security measures are not available in other interpretations of hardware wallets, which makes it a reliable means of storing coins. OLED-display is used to check all transactions and confirm them by pressing a special button.

  • Variable checking – working with such a hardware storage implies passing a transaction check using the software of a particular device to which the wallet is connected;
  • Relative confidentiality – the security of confidential information depends on the software of the device to which the connection is made. It is necessary to take care of the quality of safety in advance;
