What is a QR Barcode? What should I use them for?

March 31, 2011

A QR Barcode (Quick Response Barcode) is a 2D barcode that can store certain information such as URLs, Phone Numbers, E-mail addresses, etc. These QR barcodes can be read from web cams or mobile phone cameras.

What do we use QR Barcodes for?
We store Android Widgets URLs into them so that you can download the widgets in a few seconds from your Android Device.

How to read QR Barcodes with your Android Device:
You need to get a barcode reader application such as “Barcode Scanner”. Once you install it your device will be able to read the QR Barcodes.

I have downloaded Viber but can’t figure out how to use it through wi-fi. Can you help me? Keep it simple, I am over 60!

Hi Rena,

You just need to have your wi-fi connected and that’s it. Viber automatically uses the wi-fi network for working.
