QR means “quick response”. QR codes were originally invented in Japan by Denso-Wave (a subsidiary of Toyota). The primary goal for QR codes was to help engineers and mechanics track machine parts as they are shipped and sorted in the manufacturing line. They then expanded its use to contain more information. Today QR Codes are an emerging standard for sharing information on mobile phones.

The use of QR Codes provides an interesting new medium for sharing and distribution information. Instead of having users remember a link to type and visit using their mobile phones, one can simply snap a picture of the QR Code and immediately be taken to the URL. A long email address, a calendar event, or even a text memo of personal thoughts or official announcements can be distributed as a small square print-out of QR Code.
