Coinkite announces SATSCARD and TAPSIGNER — two NFC card products that bring Bitcoin to the tap-and-go form factor. SATSCARD is a reloadable Opendime in card form with ten address slots, while TAPSIGNER is a signing device the size of a credit card.
SATSCARD lets you load Bitcoin onto a card and hand it to someone as a bearer instrument — tap to verify, break the seal to sweep. TAPSIGNER turns any NFC-enabled phone into a hardware wallet interface. Both products made Bitcoin self-custody more accessible and physical than ever before.
Disclosure: Coinkite Inc. is the maker of this product and the publisher of this site.
