Checking a link QR before printing
Verify the destination
Scan with a separate device and read the URL before opening it. Confirm that the page is the intended one and behaves well on a phone.
Preserve the margin
Leave the white quiet zone around the code. Decorative material too close to the modules can interfere with detection.
Use the final size
A code that works on a large monitor may fail after being printed small. Test a sample at the actual size and with the actual material. SVG is useful for clean scaling, while PNG needs enough pixels for the final placement.
Try the workflow
Use the full destination, including https://. Scan the downloaded code with a second device before adding it to a printed card.
