+## OCR Feature
+
+### Cum functioneaza
+
+1. **Upload imagine** - Trage sau selecteaza poza bonului
+2. **Procesare OCR** - Click pe "Proceseaza cu OCR"
+3. **Previzualizare** - Datele extrase sunt afisate cu indicatori de incredere
+4. **Aplicare** - Click "Aplica datele in formular" pentru auto-fill
+
+### Campuri extrase automat
+
+| Camp | Acuratete estimata |
+|------|-------------------|
+| Suma (TOTAL) | 90-95% |
+| Data | 85-90% |
+| Numar bon | 80-85% |
+| Furnizor | 70-80% |
+| CUI | 85-90% |
+| Tip document | 95%+ |
+
+### OCR System Dependencies (Linux/Docker)
+
+Pentru functionarea OCR trebuie instalate:
+
+```bash
+# Ubuntu/Debian
+apt-get install -y \
+    tesseract-ocr \
+    tesseract-ocr-ron \
+    tesseract-ocr-eng \
+    poppler-utils \
+    libgl1-mesa-glx \
+    libglib2.0-0
+
+# Fedora/RHEL
+dnf install -y \
+    tesseract \
+    tesseract-langpack-ron \
+    tesseract-langpack-eng \
+    poppler-utils
+```
+
+**Note:** PaddleOCR (engine principal) se instaleaza automat cu pip. Tesseract este folosit ca fallback.
+
+### OCR API Endpoints
+
+| Method | Endpoint | Description |
+|--------|----------|-------------|
+| GET | /api/ocr/status | Check OCR service status |
+| POST | /api/ocr/extract | Extract data from uploaded image |
+| POST | /api/ocr/extract-attachment/{id} | Re-process existing attachment |
+
+### Test OCR
+
+```bash
+# Check OCR status
+curl http://localhost:8003/api/ocr/status
+
+# Extract from image
+curl -X POST -F "file=@bon.jpg" http://localhost:8003/api/ocr/extract

+## Troubleshooting
+
+### OCR not working
+
+1. Check OCR status: `curl http://localhost:8003/api/ocr/status`
+2. Install system dependencies (tesseract, poppler)
+3. Verify PaddleOCR installed: `python -c "from paddleocr import PaddleOCR"`
+
+### Low OCR accuracy
+
+- Ensure good lighting when taking receipt photos
+- Keep receipt flat (no folds/wrinkles)
+- Try PDF instead of JPG for scanned documents
+- Check if text is in focus
