What is an iCalendar QR code and how does it work
An iCalendar QR code is a QR code that stores a calendar event as a vEvent block with title, start time, end time, location and description. Scan it with any phone camera and the calendar app opens with the event already filled in, ready to save to Apple Calendar, Google Calendar, Microsoft Outlook or Thunderbird in one tap. The vEvent format follows the open IETF RFC 5545 standard, so it works across major calendar apps worldwide. No app install, no manual typing and no broken sharing links after printing.
You can add your logo, brand colours and AI-generated designs so the code matches your wedding invite, conference schedule, classroom syllabus, webinar page, worship bulletin, sports poster, concert flyer, trade-show signage, appointment card or training email. Print it on save-the-date cards, event programmes, semester handouts, webinar pages, worship sheets, season schedules, tour flyers, booth signs, appointment cards or welcome packs. iCalendar QR codes store the vEvent text directly in the pattern, so the event details stay fixed after printing and can be scanned offline with any phone camera.
