QR CODES-----THEY MEAN A LOT-----

I came across these QR codes for the first time while reading a pc suite magazine 4-5 months.
And I was like “What are these ugly-dotted-weird-squared pictures?”

The whole magazine was full of those....and it was saying...”For more links and videos Scan the above QR code”

Then I asked one of my friends that had he ever saw these type of pictures before??..and he said..”Yeah..these are bar-code kind of things that are used by smart phone and IPAD users...”

As I didnt had a smart phone and nor did I own an IPAD....I considered it trivial.

But soon I started noticing these QR codes in a lot of things....Newspapers(TOI),Movie Posters,Under Advertisements and many more...So I started surfing Internet and found that “These QR codes means a lot”---

A Brief History.....

Denso Wave (Member of Toyota) created the Quick Response Code(QR code) back in 1994 to track parts in vehicle manufacturing. Unlike other 2D symbologies,these QR code didn't require a license for there use,which helps in its popularity.

QR code was designed to allow its contents to be decoded at high speed. Japan is currently the largest user of QR codes with UK and USA heading in the same direction. 

How They Work???....

The three prominent boxes in the corners of each code indicate the location of the image (So it can be centered by the image parser).Another smaller box in the lower-right aligns the Image. The rest of the blocks indicate the information specific to the international standards (which were approved in 2000) and finally the identifying data contained within the code.

What can they do??.....

QR Codes can have a lot of different types of Data..Here I have listed some of them for your understanding----

1.URLs.....You can embed any URL like http://www.google.com in these QR code..so that anyone can Scan them and can goto that particular URL.

2.Mails....You can embed your email Address in these Codes...like--mail to:amit.kumar.agarwal16@gmail.com..

3.Text and sms...You can embed some Messages or Advertisements into the QR....Which is being used now-a-days in a  lot of Ads and Campaigns..
