Improve scanning by using suitable contrast, size and clear space around the code.

When this task helps
A QR code needs good contrast and a clear margin around it so different cameras can recognize it easily.
Worked example
A menu QR code can point to a public page on your site. Enter the full https:// URL and open it while signed out to confirm visitors can access it.
What to check before starting
Test the code on more than one device before printing or publishing it. For printed material, test at the real final size.
Choosing the settings
Use a dark code on a light background, retain the quiet margin and avoid stretching. Scan with two devices and test the final print size at a realistic distance.
Limits that affect the result
A static QR stores the supplied address. Changing the destination may require a new code unless you control an intermediate page. External link availability is not guaranteed.
Mistake to avoid
Avoid low contrast, distorted codes or design elements touching the edges of the QR pattern.
Illustrative example: size and quality depend on the source file.
