Tapsigner is a #Bitcoin cold storage device designed by Coinkite.
It's an NFC card with a secure element, offering a secure yet convenient way to store Bitcoin.
Unlike traditional hardware wallets, Tapsigner doesn't store private keys and generates them during setup.
To sign a transaction, you tap it close to an NFC-compatible device and enter a PIN.
If lost, recovery requires an encrypted backup file and the decryption key on the card.
Tapsigner supports multi-sig setups and works with specific wallets like Nunchuk and Sparrow Wallet.
It's affordable at around $40 and enhances Bitcoin security while providing a user-friendly tap-and-sign experience.
