SATSCARD is a physical bearer Bitcoin card product that allows bitcoin to change hands multiple times without requiring an on-chain transaction for each transfer. SATSCARD's Twitter Score is 14 out of 1000 as of October 2026, ranking #69,177 among 498,348 tracked accounts.
SATSCARD was developed by Coinkite, the hardware Bitcoin security company, and announced alongside TAPSIGNER in January 2022. Conceived as an NFC card equivalent of OPENDIME, it offers ten independent key slots, each capable of holding bitcoin at a sealed slot address. When the card changes hands, no blockchain transaction is needed, making the transfer function similarly to physical cash. A recipient can verify the sealed slot, pass the card on again, or permanently unseal the slot and sweep its funds into another wallet.
SATSCARD carries a factory-signed certificate embedded at manufacture, which compatible open-source software can verify without any internet connection. Nunchuk is among the compatible companion wallets, supporting Android, iOS, and desktop platforms for interacting with the card.
SATSCARD has 5,860 followers as of October 2026 and has published 383 posts. The account has been mentioned by 31 accounts a total of 96 times.
