What is QR code?

According to Wikipedia,a matrix code (or two-dimensional bar code) created by Japanese corporation Denso-Wave in 1994. The "QR" is derived from "Quick Response", as the creator intended the code to allow its contents to be decoded at high speed.

QR Codes are common in Japan, where they are currently the most popular type of two dimensional codes. Moreover, most current Japanese mobile phones can read this code with their camera.

I find that is a very interesting tool.In fact,if all products have QR code,we could use our smartphone with QR scanner to get enough information with just one click or something.

You could find a lot of QR code generator online,so you’re able to create a QR code to match any stuff you have,including your blog.

This is the QR code for my blog:

If you have Google Goggles or Barcode scanner in your mobile phone,just try to snap the QR code and see what you get.Is that great?
