A: A bar code are nothing but a series of numbers when it reads those numbers depending on the software and intention it can do all sorts of things.
Barcodes are different width lines that are coded into either numbers or characters.

There are different barcode standards and usually the database will also include the standard so that the reader and POS software can work properly.

Hi friends.... I need such a software that, when audience sends a SMS on my mobile (which is connected to my laptop), that software reads the particular code and update the database with that code and that is displayed on the screen... For example, we have 3 boys named A, B and C. People send msg on my mobile as TUR A or TUR B or TUR C or sumthing like that. That software should read this code and according to, if it is for A, the votes of A get increased by 1 and similarly for B & c.
