http://en.wikipedia.org/wiki/QR_code

You each now have a QR Reader on your laptop. You can also use a smartphone app to access a QR code as well.

This is a scan bar reader to open up a file or link

One way to set up a QR code would be to load your file/podcast/video into a wiki.

Load the file you want and then go into the Wiki Management section... right click on the file that you want to link with a qr code. choose "Copy Link Location".

Go to goo.gl. Paste the Link Location into the shortener and click on details...

copy that qr code
