How to make an event QR code
- Type the event name as you want it to appear in the calendar, for example “Riya & Arjun – Sangeet” rather than just “Function”.
- Pick the start date and time. Use the time where the event happens; your computer’s time zone is used to convert it.
- Add an end time. If you leave it empty, the event is saved as one hour long.
- Add the venue in the Location field. A full address lets the calendar app offer directions.
- Scan the preview with an iPhone and an Android phone, tap “Add to calendar”, and check that the date and time are right before printing.
Field-by-field help
- Event title
- Shown as the calendar entry name. Commas, semicolons and line breaks are escaped automatically so they do not break the event.
- Start and end
- Stored in UTC inside the code. A guest in another city sees the event at the correct local time, which matters for online events and webinars.
- Location
- A street address, a hall name with city, or a meeting link. Keep it short; long text makes the code denser.
- Description
- Optional notes such as dress code, gate number or a contact phone. Two or three short lines are plenty.
Where event QR codes help
Wedding and party invitations
Print the code on the card or the back of it. Guests save the date once instead of typing it, and the venue address comes with it.
Workshops, webinars and meetups
Put the code on the poster or the last slide of a talk so people save the next session before they leave.
School and college notices
Exam dates, parent–teacher meetings and fee deadlines go straight into parents’ calendars.
Shop sales and launches
A counter sign with the sale dates reminds customers to come back on the day.
What is inside an event QR code
The code contains a small iCalendar (VEVENT) block, the same standard that email invitations use. It lists the title, start, end, location and description as plain text.
There is no link to a server, so the code keeps working forever and nobody can see who scanned it. The flip side is that you cannot edit it after printing.
| Phone | What happens on scan |
|---|---|
| iPhone (iOS 11+) | Camera shows a banner; tapping it opens “Add Event” |
| Android with Google Lens | Shows an “Add to calendar” action |
| Older Android camera apps | May show the text only; use Google Lens |
Limits to know
- The event is fixed once printed. If the date or venue changes, you need a new code, so print only after details are final.
- Some older Android phones open the event text instead of offering “Add to calendar”. Google Lens and most scanner apps handle it.
- The code holds a single event. Recurring events (every Monday) and reminders are not included; guests can set those in their calendar.
- Very long descriptions make the code dense and harder to scan from a distance. Keep the notes short and link to a web page for the rest.
Questions people ask
Will the time be correct for guests in another city?
Yes. The time is stored in UTC and converted to the scanning phone’s time zone. Enter it as the local time where the event takes place, with your computer set to that time zone.
Can I make an all-day event?
Set the start to the morning and the end to the evening of the same day. True all-day events are not supported by every phone camera.
Does the guest need an app?
No. The built-in camera on recent iPhones and most Android phones reads event codes and opens the calendar.
