If the camera won't start
- Use a secure page: browsers only grant camera access over https (or localhost). If the permission prompt never appears, make sure the page is loaded over https.
- Check the permission: if you denied camera access before, re-allow it in your browser's site settings, then reload the page.
- Free up the camera: close video-call or camera apps that might be holding the camera.
Tips
- Lighting: Ensure even lighting; avoid glare on glossy prints.
- Distance: Move closer or farther to focus; fill ~60-80% of the frame.
- Contrast: Codes with strong contrast scan more reliably.
- Privacy: Scanning runs locally in your browser.
