Since I started using my smartphone a couple of months ago, I also started using a -for me- very stunning new technology: the QR-Code. (Or maybe not that new, since it was created on 1994. See wikipedia for more info.)
In short words, it is like a bar code, but bidimensional. Not a linear sequence of characters, but a matrix of dots, black modules arranged in a square pattern on a white background. The information encoded can be text, URL or other data.
And why did I notice it? QR is short for Quick Response because cell phones can read them very quickly. I found in the Internet a nice software for my blackberry, and there was a QR code there. I placed my mobile in front of it, the smartphone detected it and started automatically downloading and installing the software. Nothing easier.
If it is the future or not, we’ll see. In Japan it is very common, and in the rest of the world it is quickly being added to our daily environment, as shows this post from supermarketnews.com.
So would it be useful to add it to our VFC card or our blog? Of course it would. And how? Well, go to the next site to generate your own QR Code.
Next is the code to this blog. Try to scan it with your smartphone. And regards.
