QR codes are pretty awesome right? They are the new cool thing to stick on websites, menus, billboards, real estate signs, shirts, etc.
I mean you hold your phone up to them and they can give you a secret message, they can send txt messages from your phone, or give you a URL to visit. Pretty stinking cool right?
Scan these on your phone and see what they do.
The only thing is that there is no way to tell a malicious QR Code from a good QR Code. So if your QR code app doesnt tell you explicitly what it is going to do before it does it you should obviously look for a new app.
