## 🔧 Troubleshooting

### Camera Won't Start
**Problem**: "Camera access denied" or no preview

**Solutions**:
1. Check browser settings for camera permissions
2. Settings → Safari/Chrome → Camera → Allow for site
3. Close other apps using the camera
4. Refresh the page and try again

### Codes Not Scanning
**Problem**: Camera shows but doesn't detect codes

**Solutions**:
1. Move closer/farther from the code (try 4-6 inches)
2. Improve lighting (turn on overhead lights)
3. Clean camera lens with soft cloth
4. Ensure code is not damaged or dirty
5. Try holding phone at different angles

### Scan Too Slow
**Problem**: Takes long time to detect

**Solutions**:
1. Ensure code is in the blue scanning box overlay
2. Hold very still for 1-2 seconds
3. Make sure lighting is good
4. Check that code is not reflective/glossy

### Multiple Scans of Same Item
**Problem**: Same item scans twice

**Solution**: Built-in duplicate prevention waits 1.5 seconds between scans of the same code. If quantity should increment, this is correct behavior!
