A public static QR proves only that someone obtained the code, not that they were present. For meaningful attendance, use a short check-in window, authenticated form or rotating token, then retain only the records the event actually needs.
Quick answer: A public static QR proves only that someone obtained the code, not that they were present. For meaningful attendance, use a short check-in window, authenticated form or rotating token, then retain only the records the event actually needs.
Implementation workflow
- Define whether attendance needs identity, presence or only an approximate count.
- Open a time-limited authenticated check-in at the event.
- Display the code where remote participants cannot easily capture it early.
- Close the link and review duplicates or anomalies.
Professional quality checks
- Explain what data is collected and why.
- Provide staff-assisted check-in for accessibility or device issues.
- Do not expose attendee lists publicly.
Before publishing, test the complete journey on mobile over both Wi-Fi and cellular data. Record the owner, objective, review date and fallback when the destination changes. For measured campaigns, give each meaningful touchpoint its own link so the data remains interpretable.
Measure the right outcome
Total clicks or scans are only an input signal. Reconcile them with post-click outcomes such as completed forms, bookings, reviews, downloads or purchases. Exclude obvious testing and automation, compare consistent periods and annotate destination changes.
Frequently asked questions
Can screenshots defeat attendance QR?
Yes, unless the workflow uses authentication, short windows or rotating tokens.
Should GPS be required?
Usually not; location collection adds privacy risk and can still be inaccurate or spoofed.
