We recently started a site on those increasingly popular "QR codes" that offers you the ability to create your own QR code for free. Choose different colors, borders, and sizes. There are tutorial videos on the site in case you need help.
Use our QR Code Generator to make as many QR codes as you like. For websites, maps, vcards, etc.
Please give it a test run and let me know what you think and any suggestions would be helpful.
