QR Code (Quick Response Code) - A trademarked name for a type of matrix barcode originally designed for the automotive industry. Recently, the system has become popular outside of the industry due to fast readability and large storage capacity compared to standard UPC barcodes. QR codes consist of black modules arranged in a square pattern on a white background. The information encoded can be made up of four standardized kinds (modes) of data (numeric, alphanumeric, byte/binary, Kanji), or by extensions supporting virtually any kind of data.
"While QR codes have been around in the business world for quite some time the possibilities in the online, educational, and entertainment fields are just being realized."
In simple terms a QR or Quick Response Code is a type of barcode. If your mobile phone has a QR Code Reader application installed you can take a picture of the Codes and they'll link your phone to a webpage or specific content.
The primary value of Quick Response (QR) codes is in accessing information quickly and easily. All you need to access a QR code is a Smartphone or cell phone (with a camera) and barcode reader (easily available as an app if your phone's not pre-equipped).
QR codes are a two dimensional barcode that stores 7,089 characters (numbers, alphabetic, symbols, binary and/or control codes). QR code was originally created in 1994 at the Toyota subsidiary, Denso-Wave - as the traditional barcode, used in manufacturing to track and inventory parts, had a limitation of storing only 20 digits. QR codes can hold several hundred digits and function even if they are partially damaged. They are also omni-directional, which means they are readable from any direction, ensuring high speed scanning.
QR codes can be read anytime, anywhere with mobile devices. This makes them easy to decode and convenient since special scanners are not required and the camera of mobile phones simply scans and presents the information contained in the codes. One of the largest barriers preventing people from using QR codes is simply a lack of awareness of the technology.
What do you need to recognize QR codes on your phone
There are various free QR code readers out there including neoreader, kaywa and quickmark. You don't need a particularly high end phone either - but it does need to be equipped with a camera. Many Android, Nokia, and Blackberry handsets come with QR code readers installed. QR reader software is available for most mobile platforms.
Uses for QR Codes:
While QR codes have been around in the business world for quite some time the possibilities in the online, educational, and entertainment fields are just being realized. You may find that scanning a QR Code and storing or accessing data directly using your mobile phone is more convenient than taking notes. Students can point their mobile phone cameras at the codes and have instant access to information. In a lecture, students could point their mobiles at a PowerPoint presentation to download it or save urls for later use.
Some of the items QR codes can be used for include: promoting Services, Business Cards, Google Places and/or Google Maps, Contact Information, Email Addresses, Dialing Phone Numbers, SMS to Phone Number, SMS to Short Code, Text, Displaying RSS Feeds.

Future of QR Codes:
The future success will not be attributed to simply linking to url's. The real enterprise solutions are where the codes will be monetized and customization for business and commercial use will be at the forefront of intelligent and professional use, examples of which are; e-government, tourism, advertising and targeted marketing, packaging, supply chain management, brand management and brand protection, logistics, track and trace, anti-counterfeit or smuggling, id & passports, transport and ticketing, parking, disability, crm, cross media campaigns, m-ticketing, m-payments, e-learning, complete integration of localization, personalization, objects and other data.
