QR means Quick Response!

A QR code is a specific barcode (or two-dimensional code), readable by dedicated QR barcode readers and camera phones. The code consists of black modules arranged in a square pattern on a white background. The information encoded can be text, a web address or other data.

Although initially used for tracking parts in vehicle manufacturing, QR codes are now used in a much broader context, including both commercial tracking applications and convenience-oriented applications aimed at mobile phone users (known as mobile tagging).

QR codes can be used to display text to the user, to add a vCard contact to the user's device, to open a URL or to compose an email or text message. Users can also generate and print their own QR codes for others to scan and use by visiting one of several free QR code generating sites.

QR codes storing addresses and website links may appear in magazines, on signs, buses, business cards, or on just about any object. 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. This act of linking from physical world objects is known as a hardlink or physical world hyperlinks.

Most smart phone operating system supports QR codes by natively including the barcode scanner, However, on the Apple iPhone, a QR code reader is not natively included, but over 50 free Apps are available with reader and browser redirection capability.
