What Are Qr Codes And How To Make One?

 What are QR Codes? 

A QR  also called Quick Response Code is similar to bar codes, QR code encodes information in a 2-D form like in the web pages. This can be decoded by QR Code readers or Camera phones to read the information or directly go to your web page. Anything can be encoded like text, URL or any other data.

It looks something like this:

QR also called Quick Response Code


These tiny little QR codes are nowadays seen everywhere, in advertising, marketing, social networking. These codes are directly linked to the URL of your website or Facebook landing page.

  How does the cell phone read these QR codes? 

All you need is a camera phone which supports Java or Symbian application, and your phone can read QR Codes. You need to install a QR code reader, like this one from Kaywa. It takes literally 1 minute for  Android phone and other smart phones to find and install the reader.

   What Makes QR Codes Different From A Barcode? 

Barcodes store data in the 1-d format in which scanner reads only the width and distance b/w the vertical lines.  Thus providing small storage of data and fits for only identification of data. But our QR code is more advanced. It encodes data both horizontally and vertically in tiny little square shape. This makes QR codes capable of storing several hundred times the amount of data than an ordinary barcode ( approx. 3-4 kb ).
