First a bit of info:

A QR Code (Quick Response Barcode) is a system to store information on a dot matrix or a two-dimensional bar code created by Japanese corporation Denso-Wave in 1994, are characterized by the three squares that are in the corners and to detect the position of the code reader. The letters "QR" is derived from the English phrase "Quick Response" as the creator code aimed to allow its contents to be read at high speed. QR Codes are common in Japan, where they are the most popular two-dimensional code in that country.


While as many use it to download apps putting telefonito against the screen, many do not know that they can create your QR codes very simply with your Android, and would be good that we started to use more because it is much more comfortable and avoids errors of links ..

Only the BarCodeScanner abris, you give the menu and then share, gives you the option to select contacts, applications, favorite websites, etc. .. and will generate the code to toke

When you see the code on the screen you hit the menu and share again. You can send the code by mail, Facebbok, Twitter, bluetooth, etc, etc

If you are a Firefox user you can install this addons

Once installed next to the clock you see a square that if you pass the pointer shows you the QR code of the page you are viewing. The only thing that's wrong is that, for now, may not be copied to the clipboard, only read the phone. But I take a picture of the code and upload it as an image, it works well.

If you want to put the image in a post only subis to some host (eg Tinypic) and voila!

Well if anyone wants to add something or ask no problem ...
