A QR code (quick response code) is a type of 2D bar code that is used to provide fast access to information through an app on a smart phone. These codes originated in 1994 in Japan to track parts in vehicle manufacturing. Now, mobile tagging is used as the reader uses their QR reader app to click a photo of the code and read the message, open a website, view a video or even respond to a poll via SMS message.
