Do Ballet Cold Storage cards have any potential vulnerabilities?

Ballet Cold Storage cards are physical bearer assets like cash or gold; whoever has physical possession of the card has full control of the coins stored on it. Therefore they do not have protection against physical theft or loss. Nor are they fireproof or safe from corrosive chemicals. However, they are waterproof and extremely durable in normal conditions. It is the sole responsibility of the user to protect against these risks. We strongly recommend that you store your Ballet Cold Storage cards in a safe place and keep it a secret. The best protection from theft is to not let anyone know that you own cryptocurrency. Although the physical Ballet Cold Storage cards itself is safe from electronic hacking and malware, you should be aware that any cryptocurrency wallet is only as secure as the computer or mobile device it is running on. That applies equally to hardware wallets, software wallets, and Ballet non-electronic cold storage cards. Electronic hardware wallets and Ballet wallets are designed for offline cryptocurrency storage, but both require that you use a computer in order to send a transaction. Electronic hardware wallets connect to a computer by USB, bluetooth, or other type of electronic connection. Ballet Cold Storage cards “connect” visually, either by the user scanning the private key with the camera or typing the private key and passphrase manually. This process is safe, but only if the computer itself has not been compromised. If a sophisticated attacker gains physical or remote access to your computer or mobile device, it would be possible to install malware or a fake version of the app that will steal the coins from your wallet when you connect to send a transaction, or trick you to send your coins to an address controlled by the attacker.
