Destination checks

Confirm the final URL uses HTTPS.
Remove accidental staging or preview links.
Check the page on mobile data as well as Wi-Fi.
Verify phone, email, event and Wi-Fi payloads on real devices.

Visual checks

Maintain strong foreground/background contrast.
Leave a clear quiet zone around the code.
Avoid covering finder patterns with a logo.
Test at the final printed size and expected scanning distance.

Campaign checks

Add a readable fallback URL or contact method. Save the exact QR asset used in production, record its destination, and re-test after any linked page changes.
