Modern QR Code reader-apps can read VCalendar events from a QR-code and add them to your calendar. What string should I enter in a textfield for creating such a VCalendar event?
Example: http://keremerkan.net/qr-code-and-2d-code-generator/

I've tried:
BEGIN:VEVENT SUMMARY:Test Meeting DTSTART:20080811T190000Z DTEND:20080811T200000Z END:VEVENT

But my QR-code reader reads it as text and doesn't recognize it as a calendar event. Any ideas?

Thanks,

Mike.
