Satscard
Physical NFC card for gifting and trading Bitcoin like cash - tap to verify, hand over to transfer ownership.
Why We Recommend Satscard
Satscard is a non-custodial bearer device where the private key is generated and stored inside an EAL6+ certified secure element chip. The key never leaves the card or touches the internet, and users can add their own entropy (such as dice rolls) during setup to ensure keys cannot be pre-generated by the manufacturer.
The product is made by Coinkite, the same company behind the Coldcard hardware wallet and Opendime devices. Coinkite has been producing Bitcoin-focused hardware for years and is widely regarded as security-focused within the Bitcoin community. The SATSCARD protocol is fully open and auditable, allowing independent verification of how keys are generated and used.
There are no widely documented security breaches of Satscard. The device operates without any third-party servers or custody - whoever physically holds an unredeemed card controls the associated Bitcoin.
Best For
Satscard is ideal for anyone who wants to gift, tip, or trade Bitcoin in person without relying on exchanges or on-chain transactions for every transfer. The cash-like design makes it perfect for physical handoffs where possession equals ownership.
Beginners benefit from the simple user experience - there are no seed phrases to manage, just tap the card with an NFC-enabled phone to check the balance or scan the printed QR code on the back to deposit funds. The familiar credit card form factor feels intuitive compared to USB devices or complex wallet setups.
Bitcoin enthusiasts and privacy-conscious users appreciate the anonymous, trust-minimized design. No personal data is sent to servers, and physical transfers happen without creating blockchain transactions. The 10 reusable slots make it practical for multiple gifts or trades from a single card.
