What is a wallet card? A wallet card is a way to store crypto coins by printing the public and private keys on a plastic card. This “cold storage” method keeps your coins safe from hackers and malware that attempt to steal your private key from your computer. However, since the private key is on the card, the card itself must be kept safe. If I lose my card, can you send me the private key? To ensure maximum security, private keys are not saved. When the card is made, the public and private keys are created on a computer without access to the internet and then sent to the printer. The printed card is the only copy of the private key. If it’s lost, there is no way to recover it. Does the card come with coins already loaded? At this time, all the cards sold contain a 0 balance.
