QR is the abbreviation for Quick Response, as the creator intended the code to allow its contents to be decoded at high speed.

The technology has seen a large uptake in Japan and South Korea. However, broke into Europe a while back, and is now getting traction in USA. QR codes storing addresses and Uniform Resource Locators (URLs) may appear in magazines, on signs, buses, business cards, or almost any object about which users might need information. Users with a camera phone equipped with the correct reader application can scan the image of the QR code to display text, contact information, connect to a wireless network, or open a web page in the phone’s browser.
