+# tallyflow-iot Review
+
+**Tech Stack:** Rust (Cargo workspace) + Leptos (web UI)
+
+## Structure
+- `core/`: Main service/library
+  - RFID drivers (Impinj, Zebra)
+  - Barcode support (Zebra, SNAPI)
+  - REST API v1
+  - Real-time tag streaming
+  - Reader config/control
+  - Can run as Windows service
+- `web/`: Leptos CSR web interface
+  - Reader health monitoring
+  - Live tag streaming with filtering
+  - Start/stop controls
+  - Imports types directly from `core` (no duplication)
+
+## Key Capabilities
+- Hardware abstraction for multiple RFID vendors
+- Real-time data pipeline from readers → REST → web UI
+- Designed for always-on IoT deployment
+- Strong documentation (REST_API.md, LIBRARY.md, etc.)
+
+## Relevance to TallyFlow Platform
+- Primary ingestion layer for RFID/IoT data
+- Feeds the web app, reporting, and exception systems
+- Complements tallyflow-web (which consumes the data)
+
+## Next Steps for Review
+- Inspect `core/src/` for reader driver implementations
+- Review REST API endpoints in REST_API.md
+- Check web/ Leptos components for UI patterns
