How we verify this guide
Before this page is included in the public guide directory, its examples are compared with the payload produced by the linked QRFlow generator and with the export and scan-readiness controls available in the current build. Camera, lighting, paper, print size, and destination apps can still change the result, so important print runs should always be tested on the final material and real devices.
Use cases & print ideas
Matching pages that explain where this QR type works best before you open the generator.
People scan more when the QR is labeled clearly. Keep it short and specific.
Good label examples#
- "Scan to save contact" (vCard)
- "Scan for LinkedIn"
- "Scan for portfolio" (URL)
- "Scan to message me" (WhatsApp)
Match the label to the QR type#
Use vCard/business card for saving contacts, or URL for profile and portfolio links.

Business card QR code not scanning? 8 print fixes
Diagnose a business card QR code that won't scan: test the file, then fix size, quiet zone, contrast, glare, blur, vCard density, styling, or print damage.
Create a Discord QR code for server invites, avoid expiring links, and share safely.
Static vs dynamic QR code explained: what changes, what scans faster, when redirect or editable QR is worth it, and when static is enough.
Can you change a QR code destination after printing? Only with a hosted redirect link you control. Compare that path with a fixed static URL before you print.
Exact WIFI: payload format, what “Encryption” means, and how to avoid scan failures on iPhone/Android (special chars, hidden networks).
Use 20-25 mm (0.8-1.0 in) for most business cards. Includes minimum size guidance for short URLs, larger sizing for vCards, quiet zone rules, and a card dimensions chart.
Which vCard fields actually get saved on iOS/Android, what to keep minimal, and how to avoid bloating the QR for better scans.
Quick answers
Common questions
Should I use static or dynamic QR for campaigns?
Use static for stable destinations. Use hosted dynamic QR only when you have an editable short link, saved edit key, and a reason to maintain the redirect after printing.
How do I add tracking without breaking scans?
Keep UTM parameters short and avoid long redirect chains to reduce QR density.
