Scanning Tips
PDF Scanning
To scan from a PDF, take a screenshot of the code and use the "Paste" tab, or convert the PDF page to an image first.
Focus and Light
Ensure the QR code is well-lit and not blurry. Avoid reflections on glossy surfaces.
Contrast Matters
Scanning works best when there is high contrast between the pattern and background.
Steady Hand
When using the camera, keep the device steady for at least a second to allow the decoder to lock in.
Flat Surfaces
QR codes on curved surfaces (like bottles) are harder to read. Try to flatten the surface if possible.
