I think many of you have seen the barcode. Barcode is representation of data in computer readable format.In industrial production of any product,it is necessary to count each product in various stages of processing.Usually serial number of a product is coded in barcodes.There are around 200 and odd number of barcode formats.However, only few formats are universally excepted.
A simple linear barcode is shown in image below.
This barcode helps in reading the data by automated computer systems. You might have seen the usage of this code in Big bazzare or alike stores.
Another interesting code a 2-d version of barcode is a QR code(Quick Response code). It is very famous in Japan. The QR code can encode not only number but also data in large amount compared to linear barcode.
This code can be read by barcode readers. Now there is an option in android mobile to read the data. If you have android mobile you can data hidden /coded in the above QR code.(The above QR code has my personal information).
To generate QR code there are softwares as well on line links. Example: http://qrcode.kaywa.com/
I love this symbolic language of coding the information.
