How Event QR Codes Work
Event QR codes encode calendar data in the iCalendar (ICS) format — the universal standard for digital calendar events. When scanned, the user's phone prompts them to add the event to their calendar app with all the details pre-filled: title, start time, end time, location, and description.
This works with every major calendar app: Google Calendar, Apple Calendar, Outlook, Yahoo Calendar, and others. The event data is stored in the QR image — no internet connection needed at scan time.
How to Create an Event QR Code
- Enter the event title and set the start and end date/time.
- Add location and description (optional) — include the venue address and any agenda notes.
- Download and share your QR code. Print it on invitations, posters, or flyers.
Where to Use Event QR Codes
- Event invitations — physical or digital invites that add the event to guests' calendars
- Conference signage — "Scan to add this session to your calendar"
- Posters and flyers — promote upcoming events with one-scan calendar integration
- Meeting room displays — show scheduled meetings with QR codes to add them
- Wedding and party invitations — make sure guests don't forget the date
Frequently Asked Questions
Which calendar apps does this work with?
Event QR codes use the iCalendar (ICS) format, which is supported by Google Calendar, Apple Calendar, Microsoft Outlook, Yahoo Calendar, and virtually every other calendar application.
Can I include a meeting link (Zoom, Google Meet)?
Yes. Add the meeting URL in the description or location field. When the user adds the event to their calendar, the link will be right there in the event details.
What time zone is used?
The event uses your local timezone when you create it. The QR code stores the exact date and time, and the recipient's calendar app will display it in their local timezone if different.
