About

It's a wireless NFC smart card that holds your Bitcoin private key (XPRV) and will sign transactions with a simple tap on your phone. Verifiable entropy, meaning you know 100% that no one but the TAPSIGNER itself has the private key that controls the Bitcoin. Can be easily and securely backed up into a file. A simple Bitcoin wallet in your pocket. Think of it as a Bitcoin private key on a card! You can sign mobile wallet transactions by tapping the card on your phone. Your mobile wallet provides most of the wallet logic and TAPSIGNER holds the secrets. It's essentially a hardware wallet you can slip inside your regular wallet. TAPSIGNER's lower cost makes hardware wallet features and security available to a wider market around the world. TAPSIGNER is a great way to keep your keys separate from your wallet(s). The card form factor makes it easy to carry and easy to conceal. Partially signed Bitcoin transactions (PSBTs) via HWI.
