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.
Recommended templates
Zoom Meeting QR Code
Create a QR code from a Zoom join link so attendees can scan and join quickly from slides, badges, agendas, or signage.
Google Maps QR Code
Choose whether scanners need a place pin or directions, then verify the Maps opening flow before using the QR for stores, events, parking, or pickup.
Apple Maps QR Code
Turn an address, place, or Apple Maps share link into a QR code that opens Apple Maps in one scan.
Location QR Code
Turn an address or coordinates into a location QR code that opens maps in one scan.
Directions QR Code
Create a directions QR code so people can start navigation in one scan (great for parking, pickup, and events).
URL QR Code
Convert a website link to a QR code instantly, then download a clean SVG or PNG.
Use cases & print ideas
Matching pages that explain where this QR type works best before you open the generator.
For events, the QR should open a fast, mobile-friendly page and be scannable from a distance.
Before you print#
- Use a stable link that will not expire before the event.
- Test on iPhone and Android with mobile data.
- Print larger if people will scan from 1–2 meters away.
During the event#
- Add a clear call-to-action near the QR.
- Keep a backup link visible in case scanning fails.
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
How big should event QR codes be?
Print larger if people scan from 1-2 meters, especially on posters.
Do I need a backup link?
Yes. Add a short URL near the QR in case scanning fails.
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.
