About Tapsigner

The Tapsigner is a credit-card-shaped NFC-based Bitcoin signing device from Coinkite. It stores a single Bitcoin private key and signs transactions when tapped against an NFC-enabled phone. Designed for simplicity and portability, it targets users who want a minimal, low-cost Bitcoin signing solution without the complexity of a full hardware wallet. It works with compatible wallet apps like Nunchuk.
