How to create a QR code business card

If you own a smart phone - or an even smarter phone you probably already know what an QR code is. If you don't know I a sure you will have seen this somewhere on the web or in a magazine.

A QR code is a two-dimensional barcode. A big part of it consists of error correcting code and it somehow looks funny. I was looking for a possibility to share my contact coordinates or even calendar entries for smart-phones when I stumled across http://zxing.appspot.com/generator/

With that webpage you can create these QR codes for your business card, for coordinates and for calendar events. When you try the calendar event, test the QR code before you use it. Daylight savings time is a real *****. When I tested it on my HTC Desire with Barcode Scanner I experienced a strange bug. Every calendar event I created lasted only for 1 hour. Even when it was supposed to be longer.

Anyone with Blackberry or Iphone experiencing the same behaviour?
