So you walk past a shop in the mall and spots this funny looking box stuck to the window and you think ‘What is that THING?’ Well, if it is black and white and looks like a pixelated patch, it’s a QR Code.

A QR Code is a matrix code (or two-dimensional bar code) created by Japanese corporation Denso-Wave and is the most popular open 2D-Code for Mobile Tagging. The “QR” stands for “Quick Response”, as the creator intended the code to allow its contents to be decoded at high speed.
