What is a QR code?

Believe it or not QR or Quick Repsonse codes have been around for a while now. QR Codes are common in Japan, where they are currently the most popular type of two dimensional codes.

A QR Code is a matrix code (or two-dimensional bar code) created by Japanese corporation Denso-Wave in 1994. The creator intended the code to allow its contents to be decoded at high speed.

QR Codes storing addresses and URLs may appear in magazines, on signs, buses, business cards or just about any object that users might need information about. Users with a camera phone equipped with the correct reader software can scan the image of the QR Code causing the phone’s browser to launch and redirect to the programmed URL.

You can use your phone to read QR codes by installing Kaywa Reader.

And make your own QR code like we have below on the same kaywa site.
