event qr code calendar
Event QR Codes are useful on invitations, talks, conference schedules and posters. The iCalendar/VEVENT format is recognized by many calendar apps, but each app decides how to import the content. The best event QR is clear, short and explicit about start, end and location.
Times are serialized in UTC for interoperability.
Keep the description short to preserve scanning in small print.
Generating the same QR Code again, with the same four fields, produces the same UID, which helps calendar apps recognize it as the same event instead of creating a duplicate copy.
Yes. In addition to text, URL, Wi-Fi, email, phone and SMS, it generates vCard 4.0 contacts and iCalendar/VEVENT events for import by compatible apps.
Usually not without confirmation. Responsible apps show a preview and ask permission to save the event, because events can contain sensitive data or alarms.
Use clear times, test on target devices and prefer UTC in the payload when the event does not depend on a specific regional rule. For complex global events, a registration page with detected timezone is often more reliable.
Because the tool converts the chosen local time to UTC before generating the payload, reducing ambiguity when the invitation circulates among people in different time zones. The calendar app that scans the QR Code takes care of displaying the time already converted to the device's own time zone.
The QR Code is generated in your browser. Content, Wi-Fi, contact and event data are not sent to the server.
