A QR Code (it stands for "Quick Response") is a mobile phone readable bar code that can store website URL's, plain text, phone numbers, email addresses and pretty much any other alphanumeric data.
There are many QR Code Generators on the web that will allow you to create either dynamic or static QR codes and download them for immediate use.
Storing up to 4296 characters they are internationally standardized under ISO 18004, so a QR code is a QR code all over the world - they've been big in Japan forever, broke into Europe and the UK a few years back, and are now popular in North America.
Think "print-based hypertext links" and you'll get the idea.

Tips and Tricks
- decide which web page the user should get when they scan the code (the landing page) (advanced: you can use different codes to track which poster got them to a single page)
- know the format of your original material
- go to a free qr code generator site (such as www.qrstuff.com)
- put in the web URL that the user goes to
- download the resulting code image
- add the image to the flier
- for image based source, use an image compositor like GIMP (free) or other
- for text or other source, add the QR image using the existing tool
- save the result and print
- General experience is that it takes less than 15-30 minutes to do this the first time, plus whatever time you put into creating the landing page. After that, it is just an extra couple minutes.
- Use the tools you know best, almost anything can add an image to a source document.
- You can make this part of a header/footer and create a template for all your fliers.
