QR Code

Yesterday after I posted about the unique bar code, I remembered another type of code I bumped across few weeks back.It’s called a QR Code.  What is  QR Code?? Well it’s simply a two dimensional bar code. But the QR code is capable of carrying much more information than a bar code as it can carry data in the vertical direction as well as the horizontal.

Anyway this type of code looks really cool too. Using a QR code generator you can generate a QR Code with almost any text data you want. And as the bar code, you need to have a special reader to read this type of codes. But the best part is we can install this reader in our mobile phones and we can decrypt the QR code in few seconds.

Here I generated a code with my name and blog URL.

You can easily find QR code generators as well as readers on the web for free.
