QR codes are machine-readable optical labels first designed in 1994 for the automotive industry in Japan. Typically, a smartphone is used as a QR code scanner to convert the code into some useful form (such as a standard URL for a website, thereby obviating the need for a user to type it into a web browser).
We're trying to be as eco-friendly as possible, so this July we'll be hanging posters with the QR code above around the LATEA theater entrance so patrons can view our festibill program insert directly on their smart phones. Try it out now and yes we are tree lovers in Colorado.
