How to Create an Event QR Code
1. Enter Event & Timing Details
Set your event title, physical location or virtual URL, start date and time, end date, and description.
2. Standard iCalendar VEVENT Protocol
HoldQR formats your event into standard RFC 5545 iCalendar syntax natively recognized by iOS Calendar and Google Calendar.
3. Print on Invites, Posters & Tickets
Download vector SVG or high-res PNG to add to event posters, wedding invitation cards, conference name badges, and tickets.
Eliminating No-Shows with Calendar QR Codes
Automatic Phone Reminders
When attendees scan and save your event, their mobile operating system automatically schedules native 15-minute and 1-hour notifications before the start time, dramatically reducing no-shows and late arrivals.
Wedding & Conference Badges
Print calendar QR codes on wedding invitation envelopes, save-the-date magnets, or corporate badge schedules so attendees don’t miss keynote speeches or cocktail hour start times.
Frequently Asked Questions
How does an attendee add the event to their calendar?
When an iPhone or Android user points their camera at your event QR code, a notification prompt appears asking "Add to Calendar". Tapping it opens their native calendar app with the date, time, venue, and description already entered, ready to save with 1 tap.
Does this work with both Google Calendar and Apple Calendar?
Yes! The standard iCalendar (VEVENT) schema is the universal format supported by Apple iOS Calendar, Google Calendar, Microsoft Outlook, and Yahoo Calendar.
Do attendees need an active internet connection to save the event?
No! The event timing, title, and venue details are stored completely offline inside the QR code dots. The calendar app opens and saves the event locally even in airplane mode.
Can I change the event date or time after printing posters?
Because static calendar QR codes permanently encode the date and time in the print, you cannot change the schedule without reprinting. If your event schedule might change, explore HoldQR dynamic QR codes pointing to a live schedule landing page.
