Are Ballet Cold Storage cards safe from electronic hacking?

Ballet Cold Storage cards have no electronic components, so it is impossible to hack it through an internet or local connection. The only way to read the private key entropy and passphrase entropy from a Ballet Cold Storage card is visually, after you physically remove the tamper-evident sticker and scratch-off material. Although the physical Ballet Cold Storage 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 wallets. 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 entropy and passphrase entropy 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.
