What is QR code? How to generate it?

Quick Response (QR) code is a matrix barcode. This matrix barcode is a two-dimensional code that can be read by QR barcode readers and even camera mobile phones. Unlike a normal barcode that has a series of lines, a QR code survey is made up of black modules arranged in a square pattern on a white background. The function however remains the same: to store information.


Originally, this code was used only to track parts in vehicle production. These days it is used for other things such as storing contact information, URLs or texts. The encoded information can be interpreted by a camera phone that is equipped with a dedicated software or application. When a phone camera scans and interprets a QR code survey that contains a URL of a web page, the page will automatically opens in your phone’s browser. This process is called hard-linking or object hyper-linking.


In recent years, the code has been commonly used as a marketing tool. It is not uncommon to see it on a billboard or in a magazine. Targeted customers can scan the code using their phone and instantly receive information about the advertised product. In Japan, the QR code is used in almost everything such as for buying an application for your smart phone, subscribing to your favorite celebrity’s blog, or buying the latest digital music release.


Mobile phones that are equipped by a dedicated scanner camera are almost widely sold in countries such as Japan, South Korea and The Netherlands. However, most Blackberry devices and Android or Symbian based devices sold worldwide are also equipped with a scanner software. If you are a Blackberry user, you do not have to ask another user’s PIN number to add him/her on your Blackberry Messenger. You can just scan the other device’s QR code and that person will be added into your contact list.

You only have to visit one of these websites, enter the type of information (data or text) that you want to store in the code. You are usually asked to fill in your personal details such as your name, company or employer, phone number, e-mail or other similar information. The website will then generate a code that contains your personal information just like what you have typed earlier. You can then print the image and distribute it as you like.
