Offline Cash (The Bitcoin Note)
Physical secure Bitcoin that you can easily share, spend, or hold.
Offline Cash sells physical Bitcoin notes designed as self-custodial bearer instruments. Each note embeds an NFC chip holding two private keys (a plaintext user key and an encrypted manufacturer key) and a Bitcoin P2SH address requiring both keys before the claim-by date, or only the user key after it. An open source client app communicates with a note server to verify, re-key and claim notes. The first release is limited to 2100 packs.
