QR Code Guide: What to Encode and How to Use It | SmartToolz

What can a QR code contain?

Common uses include website URLs, plain text, contact details, Wi-Fi information and other structured strings supported by the scanning app. Decide what the recipient should do after scanning before creating the code.

Keep the destination useful

If the QR code points to a website, make sure the destination works on phones and does not require unnecessary steps. For printed material, avoid changing the destination without testing the final printed code.

Test before publishing

Scan the generated code with more than one phone when possible. Test it at the approximate distance and lighting where people will use it. A code that scans perfectly on a large monitor may be harder to scan when printed very small.

For clean results

• Leave a clear margin around the QR pattern.
• Use strong contrast between the code and its background.
• Avoid covering the pattern with text or decoration.
• Test the final image or print before sharing it.
