just fascinated with what QR codes are able to do

maybe this article is very 1950s for  you..... although the birth of QR code has been actually in 1994...... but for some of you, this can be VERY 2011.
scan this QR code using
a bar-code reader application in
your smartphone and see what
it gives you in return

  • making a video commercial for your new product and looking for ways to make it viral?
  • spreading around a web URL of a issue-based campaign which you are running in your community?
  • trying to motivate people to send a text msg to your company for your new promotional deal, without having your customers to type out a single thing?
  • making a new texture for your t-shirt which will take the mobile users to your personal blog site?
  • inviting guests to your brother's wedding ceremony without having to print out the expensively eco-unfriendly paper cards?
  • promoting a WE HAVE MOVED address location of your office/showroom without any text but of course with an interactive googleMap?
  • making a one-snap access for your coffee-shop customers to log into your wifi hotspot without having your customers to go through the hassle of device authentication?
  • driving traffic to your blog........... or facebook profile..... or twitter profile....... or youtube channel....... or any social network profile?
  • spreading out the link of a new iPhone application you have just released in the appStore?
  • or simply using your cellphone screen instead of carrying business cards, to exchange contact information with new people you have met at a business conference?
the answer is QR code.

QR code stands for QuickResponse code.
It was made first by a Toyota subsidiary called Denso-Wave in 1994.
This is a 2-dimensional matrix barcode (as opposed to the familiar 1-dimensional barcode which we see in our grocery products, cosmetics, stationaries, price-tags etc)
Hence, the number of unique combinations of pixels that can be made out of a 2-dimensional QR code is far more greater than the number of unique combinations that can be made out of a traditional 1-dimensional barcode.
As a result, unlike the traditional 1-dimensional barCode, a QR code not only gives information about an object, but it also brings in interactions with the person who is scanning the code - refer to the few examples i have tried to show above.
The QR code has been made primarily for the general smartphone users.
It can be read by QR barcode readers or cellphone cameras.
And it can be created by anyone for free using various sites available in the web - my personal favorite is
