  Blockchain cards are physical devices that store private keys and other sensitive information related to digital currencies. These cards provide an extra layer of security by keeping the private keys offline and away from potential hackers. When a transaction needs to be made, the user can insert the blockchain card into a compatible device and authorize the transaction using the private key stored on the card. This ensures that even if the user's computer or online wallet is compromised, the private keys remain secure on the offline blockchain card.

Additionally, blockchain cards often come with built-in encryption and authentication features, further enhancing their security. Overall, the use of blockchain cards provides users with peace of mind knowing that their digital currencies are protected by an extra layer of security.
