What is QR Code?

I was just wondering what are these images... I knew for sure that these were targeted for mobile phones. But noting more than that. What are they used for? How are they used?...

Most of you at some point of time definitely must have come across these boxes with black and white patterns. You generally find it in newspaper advertisements...Flex boards placed on highways....

Yesterday I figured out that these are bar codes designed for mobile phones. The bar code reader is your camera mobile phone.

I tried it..its really interesting.. you can read these QR barcodes with your mobile phone....just that you need to install a bar code reader software. Which can be freely downloaded from internet.


The interesting part is that you can create these codes you own..there are many web sites which offer this service.

Now, coming to the code..what data can be encoded.. Text, SMS, Phone Number, Address, URL.

Use Case1: Point your camera to a QR code placed in a flex board adv. go to the web site in one click.
Use Case2: Point your camera to a QR code in a news paper adv. call the guy in one click.
Use Case3: Point your camera to a QR code in a news paper adv. send an SMS

In fact, use of this code is limited to your imagination.

So, here's your home work.. scan the QR code I have given above with your mobile and see my secret message to you....enjoy!!
