What is a QR code?

QR codes are two-dimensional embedded codes that are designed to be read by QR code readers.  Originally QR codes were developed in the 1990's as a form of inventory tracking, however, with the increased usage of mobile devices in later years, QR codes began to be used as a method of connecting mobile device users to specific pieces of web-based information.
