Looking for a new and innovative way to leave a message? Or do you want to be especially dorky and put a QR code on your business card? Jump on the bandwagon and visit the QR Code Generator. It's free, easy to use and it works!

As an added bonus, on particularly slow days you can leave messages for your coworkers embedded in these QR codes. If they don't own a smartphone, it will take a while before they figure out what it says. Much more likely is that they throw it away without ever knowing there was a message in there.
