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.
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.
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.
Use a username for profiles and a permanent invite for groups.
Do short links help?
Yes. Shorter links scan faster on small prints.
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.
