A day will come when all you have to do to download/share a file with others is just scan it using your phone and voila!! You’re done. This is possible thanks to the very much expanding means of sharing files known as QR Codes. QR stands for Quick Response and is basically a 2/3-dimensional bar code that stores information of almost any kind. All you have to do to retrieve the data is scan it using your mobile device.
Here’s a tutorial on how to add these QR codes on your blog.
It’s really very simple, it’s just an addition of Google’s Chart API into the html of your blog.
- First you’ll need to create the QR code of what you want to share on your blog. It can be a link, an image, some information or any data. To create a QR code, you can use Google URL shortner Goo.gl and create one in a jiffy. Create a short URL of the link, for example “http://goo.gl/2whlk” is a short link for this website and add “.qr” to it’s end, like this “http://goo.gl/2whlk.qr” . It will look something like this(below), you will find the original QR Code here.
- Next step is to mess with your WordPress or blog theme. You’ll need to open the Single Post.php and add a line of code after the <?php – ?> tags. The code will look like this : <img src=”http://chart.apis.google.com/chart?cht=qr&chs=150×150&choe=<?php the_permalink(); ?>” width=”100″ height=”100″ />. You can then add necessary changes to add title and give it a center layout and other format stuff.
- Save/Update the file and you should be able to see it on your page.
- There is another hassle free way also. That includes the installation of a QR plugin on your blog known as the Super Cool QRCode WordPress plugin. Once installed you just have to paste the Goo.gl shortened URL with the .qr extension in the required column.
If you did not get it, then watch this video below.
That’s all folks. Download the QR Reader apps for your respective mobile devices and start playing with QR Codes. This is the future of sharing.
