QR codes are bar codes that can hold secret messages or URL’s that you can create and then read with a smart phone.  All someone needs to read a QR code is a smart phone with a camera and a free app like Red Laser.  QR codes can be a convenient way to transfer a long URL to a cell phone.  They can be used on print advertisements or can be scanned directly from a computer screen.  Best of all QR codes are free and easy to make!
