It is built on a sovereign digital identity MPI (Master Patient Index), HL7 FHIR R4 interoperable, and designed to operate in low-connectivity environments. *** ## What Oomus CampaignID does Oomus CampaignID enables national health programs and humanitarian organizations to: * **Generate** secure digital health cards at scale * **Distribute** cards via WhatsApp, SMS, and Google Wallet from a unified interface * **Verify** the authenticity of cards offline — no Internet connection required * **Deduplicate** identities automatically thanks to the probabilistic MPI engine * **Synchronize** data from DHIS2 Tracker in real time * **Govern** access, quotas, and approvals via an institutional RBAC system * **Issue** Sovereign Wallet Passes — signed digital passes, syncable offline * **Produce** physical PVC cards in two print qualities * **Bill** with full traceability — every debit automatically generates a signed formal invoice * **Access** sovereign identity from the mobile app **OOMUS Wallet** (iOS + Android) — bilingual FR/EN * **Verify** their identity with the 5-step KYC wizard (ID card + biometric selfie) — MPI trust score updated in real time * **View** the Sovereign Identity Register — IAL levels 0–3, unlocked features, cryptographic integrity *** ## Key capabilities * **Card Studio** — Visual editor with 11 card templates, real-time preview, export, 300/450/600 DPI options * **Sovereign digital identities** — 1 citizen = 1 MPI digital health identifier, cross-program, lifetime * **DHIS2 integration** — Automatic synchronization, attribute mapping, generation from enrollments * **Multichannel distribution** — WhatsApp (Meta Graph API), SMS (Orange API), Google Wallet * **Offline verification** — Static portal, browser-side cryptography, multilingual (FR/EN/WO) * **Sovereign Wallet** — Signed digital passes, offline bundle, device sync, audited revocation * **Financial simulation** — Pro forma estimate, admin approval workflow, PDF/Excel generation * **Physical PVC cards** — Standard and Industrial Offset, tracking timeline * **Billing Infrastructure** — Centralized accounting ledger with signed invoices and immutable audit * **Operational dashboard** — Real-time KPIs, advanced analytics, alerts * **Enterprise security** — 2FA TOTP, brute-force protection, JTI token revocation, institutional RBAC * **Bilingual mobile app** — OOMUS Wallet React Native / Expo SDK 54 — FR/EN, biometrics, offline-first * **5-step KYC wizard** — ID card verification + selfie, MPI trust score propagated in real time via WebSocket * **Real-time Citizen Wallet** — live activity, `ACTION_LABELS` human labels, filters, animated toasts * **Sovereign Identity Register** — IAL levels 0–3, cryptographic fingerprint, error reporting *** ## Who it's for | Target audience | Typical use case | | ---------------------------- | --------------------------------------------------------- | | National health programs | Vaccination, malaria, nutrition, HIV/PMTCT | | Ministries of Health | Universal health insurance card, national health identity | | Humanitarian agencies & NGOs | Refugee identification, mosquito net distribution | | Government agencies | National identity linked to health services | | Agricultural health programs | Farmer card / rural health | *** ## Available plans | Plan | Identities/month | SMS/month | WhatsApp/month | | --------------------------- | ---------------- | --------- | -------------- | | **Essential** | 10 000 | 50 000 | 10 000 | | **Regional Command** | 100 000 | 250 000 | 100 000 | | **National Infrastructure** | 1 000 000 | 3 000 000 | 1 000 000 | | **Sovereign Cloud** | Unlimited | Unlimited | Unlimited | *** ## Tech stack | Component | Technology | | -------------------- | ----------------------------------------------------------------- | | Frontend | Next.js + React + TypeScript | | Backend | FastAPI + Python + SQLAlchemy | | Database | PostgreSQL 16 | | Task queues | Celery + Redis | | File storage | S3-compatible | | Interoperability | HL7 FHIR R4 | | **Mobile app** | React Native 0.81.5 · Expo SDK 54 · TypeScript · i18next (FR/EN) | | **Mobile real-time** | WebSocket + Redis pubsub · SyncContext · `publish_wallet_event()` | | **KYC Trust Bridge** | `kyc_trust_bridge.py` · `MpiTrustScore` · `MpiVerificationEvent` | *** ## Start now Go to [Quick start](/getting-started/quick-start.md) to create your first program and generate your first cards. See the [Plans & Features](/getting-started/plans-and-pricing.md) to choose the plan suited to your program. *** *** ## Mobile app — OOMUS Wallet The mobile app **OOMUS Wallet** (React Native / Expo SDK 54) allows every citizen to access their sovereign MPI identity, their health passes, and control the sharing of their data from their phone. **Key features:** * SMS OTP login → 6-digit PIN → biometrics (Face ID / Fingerprint) * Sovereign identity card `SovereignCard` with HMAC-SHA256 QR * **5-step KYC wizard** — ID card + biometric selfie, MPI score updated in real time after completion * **Citizen Wallet** — WebSocket live activity, `ACTION_LABELS` human labels, All/Wallet/Health/Identity filters * **Sovereign Identity Register** — IAL levels 0–3, cryptographic fingerprint, error reporting, unlocked services * Management of health passes (vaccination, insurance, prescription…) with overlay `IAL level {n} required` * Sharing consents with 2-step GrantModal * Complete activity log — human labels, fallback `'System event'` * Health insurance module — coverage, procedure verification, history * **Bilingual FR/EN** — language selector in Settings, AsyncStorage persistence * Offline mode (SyncContext) — passes and identity cached, auto-sync when network returns **Getting started:** ```bash cd mobile npm install npx expo start # Expo Go QR code npx expo run:ios # iOS simulator npx expo run:android # Android emulator ``` **Environment variables:** ```bash EXPO_PUBLIC_API_URL=https://api.oomus.org # backend URL ``` *** > **Oomus CampaignID** — *One identity. One citizen. One sovereign health system.* --- # Agent Instructions This documentation is published with GitBook.
