What is an iCalendar QR code and how does it work
An iCalendar QR code is a QR code that encodes a calendar event (a vEvent block with title, start time, end time, location and description). Scan with any phone camera, the calendar app opens with the event pre-populated for one-tap save into Apple Calendar, Google Calendar, Microsoft Outlook or Thunderbird. The vEvent format is defined by the open IETF RFC 5545 standard, so codes work across every major calendar app worldwide. No app install, no manual typing, no broken share links once printed.
Add your logo, brand colors and AI-designed pixel art so codes match your wedding-invitation stationery, conference-program layout, classroom syllabus, webinar landing page, religious-service bulletin, sports-team poster, concert flyer, trade-show booth signage, medical appointment card or subscription-cohort welcome email. Print on save-the-dates, conference programs, semester syllabi, webinar landing pages, worship bulletins, season schedules, tour flyers, booth signage, appointment cards or training-cohort welcome packets. iCalendar QRs encode the vEvent text directly into the pixel pattern, so the event data stays permanent once printed and works offline on any phone camera worldwide.
