Off-Grid payments and ID
summary
A working system combines a biometric smart card (fingerprint sensor, e‑ink display, secure enclave, Bluetooth/NFC/USB) with mobile wallets and a permissioned distributed ledger (forks of Ripple and BRD, planned Finract and Mojaloop integration). Cards hold a tiny offline ledger with anti‑double‑spend measures like an expiring offline currency and periodic sync; prototypes cost ~$10–15 now, target $4–10 in volume. Field tests touch ~2,000 users, rechargeable cards last months, custom low‑power SoC and agent onboarding are required, software will be open source and hardware pushed toward open standards.
