+### QR Code Sharing Feature
+The application includes dynamic QR code generation for easy campaign and response wall sharing.
+
+**Key Features:**
+- **Campaign QR Codes**: Generate scannable QR codes for campaign pages
+- **Response Wall QR Codes**: Share response walls with QR codes for mobile scanning
+- **High-Quality Generation**: 400x400px PNG images with high error correction (level H)
+- **Download Support**: One-click download of QR code images for printing or sharing
+- **Social Integration**: QR code button alongside social share buttons (Facebook, Twitter, LinkedIn, etc.)
+- **Caching**: QR codes cached for 1 hour to improve performance
+
+**How to Use:**
+1. Visit any campaign page or response wall
+2. Click the QR code icon (📱) in the social share buttons section
+3. A modal appears with the generated QR code
+4. Scan with any smartphone camera to visit the page
+5. Click "Download QR Code" to save the image for printing or sharing
+
+**Technical Implementation:**
+- Backend endpoint: `GET /api/campaigns/:slug/qrcode?type=campaign|response-wall`
+- Uses `qrcode` npm package for generation
+- Proper MIME type and cache headers
+- Modal UI with download functionality
+
+**Use Cases:**
+- Print QR codes on flyers and posters for offline campaign promotion
+- Share QR codes in presentations and meetings
+- Include in email newsletters for mobile-friendly access
+- Display at events for easy sign-up
+
