What is QR A QR Code is a matrix code (or two-dimensional bar code)

The initials "QR" mean "Quick Response". The "quick" part of "quick response" refers to the intention that these images, when scanned, allow the contents to be decoded very quickly,  and therefore a
 o series of text words could be read
 o or a URL could be found

Originally created by Denso-Wave in Japan - QR Codes are common in Japan (2008-2009). Most current Japanese mobile phones can read this code with their camera.

Micro QR Code is a smaller version of the QR Code standard. Works when a phone cannot handle large scans

 
In 2009 April, Simon and his group (Team anyshirt.ca)

in the course MGD415 at UTM (University of Toronto) demonstrated a new technology that allows mobile devices to "read" an image, which then allows you to connect to a website.

Shown in the pic to the left is a T-shirt made by Simon, with the QR code for my name "Richardson"

this pic shows Simon "reading" the QR code with his SmartPhone, and, with a connection to the web turned on, his phone then brings up the webpage associated with the particular QR code

How did it start Initial appplication was for identifying auto parts in manufacturing.

By 2009, QR Codes now have many applications - one of the most opular apps thatis getting the greatest recognition is how the technology is used in camera-equipped mobile phones - commonly referred to as mobile tagging.

Watch the video for an intro to the basic functionality of QR codes, as well as some history on how they started, and also some insight as to how they are being used in late 2009.

Branavaa also included the clip from the CSI New York Episode in which QR codes are discussed.

In December 2009, UTSC student Branavaa D. finished his report on the basics of QR codes and for the sake of students having an intro to the topic, we have included the report here, in a PDF document, which you can access by clicking on the screen capture to the left.
