QR code

 
 
QR code (Quick Response) is a matrix code created by Japanese corporation Denso-Wave.
It is a two-dimensional bar code which can store up to 7kB of data, such as: plain text, mobile telephone numbers along with a SMS message, contact cards (e.g VCards), geographic information, images and other information.

QR code: Welcome to Mobilefish.com

Example QR code, the message is: Welcome to Mobilefish.com

If a mobile phone is equipped with the correct reader software it can scan the QR Code.
Dependant on the keyword found, the mobile phone determines which action to be taken.

For example:
If the keyword http:// is found, it will cause the phone's browser to launch and redirect to the programmed URL.
The keyword is always the first few charaters of the message.

QR Code is open in the sense that the specification of QR Code is disclosed and that the patent right owned by Denso Wave is not exercised.
