About

TAPSIGNER is a reusable, screenless NFC hardware signer from Coinkite. A compatible wallet builds and displays the transaction; the card holds the BIP-32 key and signs after a physical tap and PIN entry. Current integrations listed by the first-party site include Nunchuk, Cove, Bitcoin Keeper, and Sparrow. Recovery uses an encrypted XPRV backup plus a separate decryption key. Because the card has no display, transaction review depends on the companion wallet.
