We have noted that Facebook has started to test using QR Codes on their applications.
QR Codes are Quick response Codes ... Quick , because it is easily read. Response , because you can store plenty of information on it. Code, simply becaause it is a Code and needs to be decoded to be used.
A QR Code is a matrix code (or two-dimensional bar code) created by Japanese corporation Denso-Wave in 1994. The "QR" is derived from "Quick Response", as the creator intended the code to allow its contents to be decoded at high speed. It was invented by the Japanese company Denso Wave
QR Codes became first common in Japan, and has slowly spread over the rest of the world. Most new mobile phones will have a QR Code application. With this application you can scan a CR Code with the camera on your phone and the application will then generate an Url for a web address.

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).
You might have noticed that QR Codes may appear in magazines, on signs, buses, business cards, or just about any object that users might need information about. Users with a camera phone equipped with the correct reader software can scan the image of the QR Code causing the phone's browser to launch and redirect to the programmed URL.
This act of linking from physical world objects is known as a hardlink or physical world hyperlinks. Google's mobile Android operating system supports the use of QR codes by natively including the barcode scanner (ZXing) on some models and the browser supports URI redirection, which allows QR Codes to send data to existing applications on the device. Nokia's symbian operating system is also provided with a barcode scanner, which is able to read QR Codes.
Users can also generate and print their own QR Code for others to scan and use by visiting one of several free QR Code generating sites. Such as : Beetag
and many others.So how will this be used ?
Well by including QR Codes on things that you want people to remember, you give other people an easy way of remembering it.
