Use the final destination, create the code at a clear size, test it from the printed or displayed version, and place a readable destination or explanation beside it.
Create a useful QR code, test it on more than one device and help people understand where it will take them before they decide to scan safely. This guide explains a practical workflow, the limits to keep in mind and the checks worth making before you use the result.
Prepare the destination first
A QR code only represents the information placed inside it. Check the web address, text, contact detail or WiFi information carefully before creating the image.
Prefer a stable page you control for long term campaigns. If the destination changes, a static code will continue pointing to the old value.
Design for reliable scanning
Keep strong contrast between the dark pattern and its light background. Leave clear space around the code and avoid placing important graphics over its squares.
The physical size depends on viewing distance and printing quality. Test the actual poster, card or screen instead of checking only the large file on your computer.
Tell people what to expect
A short label beside the code builds confidence. Explain whether it opens a menu, form, contact card or payment page. Show a readable domain when a web link is involved.
Do not use a QR code to hide a surprising destination. Clear context helps visitors decide whether they want to scan.
Test and maintain it
Scan with more than one phone and camera application. Test under ordinary lighting and confirm that the final printed colours have enough contrast.
Review important campaign destinations over time. A working QR image is not useful if the page behind it has moved, expired or become unsafe.
Practical checklist
- Verify the destination before creating.
- Keep a clear margin around the pattern.
- Label what the code opens.
- Test the final printed or displayed version.

Frequently asked questions
Can a QR code expire?
A static QR image does not expire, but the page or service it points to can change or disappear.
Why will my QR code not scan?
Low contrast, a small size, a damaged pattern or insufficient clear space can prevent reliable scanning.
Should I put a logo inside the code?
Only when you can test the result carefully. Covering too much of the pattern can make scanning unreliable.
