QR Code

Image can be used for message transactions. For the past couple of day I was experimenting QR code (off course out of curiosity), I accidentally came to know this term while wasting time on net. On further investigation I found it is interesting and worth to try.

QR code (Quick Response code) may be new to me but it was originally invented  by Denso-Wave in 1994. In an abstract point of view QR code can store small information (text, numbers, URL, Kanji/Kana character) begin the image.  And it is consider to best alternative to bar-codes. Bar-code has ability to store information in horizontal phase but QR code can store information both horizontally and vertically that make QR code to hold more data than ordinary bar-code.

Today QR code readers are compatible with all smart phones. They are used as an additional resource to the communication system.  For example I have seen a new paper ad that has QR code on the side. On taking a snap of the QR code with a smart phone that has installed QR reader, will  directly  take you to the website of the ad. (This is interesting isn’t.)

And it is not necessary that you have to own a smart phone to experiment this, pc based and online based tool are also available. Yet I have made a simple application that use the open library for encoding and decoding there by my application is cable of  generating  and reading QR codes on pc based platform (Linux / windows ).

    Great program! I`m using Linux and finally I can create and read QR codes in the same application. I have a suggestion, could You enhance Your application so that it works with other types of 2D barcodes also (for example Datamatrix)?

    I believe that you need to write extra on this topic QR Code for desktop – shakthydoss. It might not be a taboo subject but typically persons are not sufficient to speak on such topics.
