What are these squares? QR Code?

If you've been using a Smart Phone, you probably are familiar with these "squares" or the Quick Response Code or the QR code.  In general, these are a type of barcode that contains much more information than the traditional 2D barcode that you typically see such as the UPC.


You probably see them everywhere nowadays.  On a lot of products.  The idea is it allows you to use your smart phone, such as your HTC EVO 3D, to instantly search on information on the product. 

There are many "scanner" apps you could download from the Android Market.  For me, I've downloaded the free "ScanLife" app.  

It is pretty easy to use, you download from the Market, install it.  Then, when you want to scan something, you just open that app, point at the barcode in the "rectangle" box, it will then search and take you to the information.

For example, when I scan the QR code on this marigold plant tab, I brought me to the following website directly for information.

Usually, scanner apps like this also be able to scan 2D regular barcode.  For example, I used it for scan this barcode - 

It brings me to product information and where I can buy, etc details here

Of course, it is a type of information collections.  It's a type analytic data for businesses.  But for us the consumer, this could come in handle, when you are away from your computer and would like to look up some info.  It's a cool way to go.  You probably also have seen those QR codes on your boarding passes and other things.
