You can transfer bitcoin off of a Physical Bitcoin card or coin by using the Ballet Crypto app. Simply select your card or coin in the app (add your card to the app if you haven’t already), tap “Send”, enter the amount you want to send and the destination bitcoin address of your choice, complete the security steps (enter passphrase entropy and scan private key entropy), and then finalize the transaction.
You can also transfer bitcoin off a Physical Bitcoin card or coin using any crypto wallet that supports BIP38 two-factor private keys.
