First you need some data (like a picture).
Then transform the data into a line.
Then devide this line in areas and each
area should reprecent a number. Add these
numbers strings together and then parse to
a long and return the long.

I haven't done this at all and I have no
idea what I am taking about but this sound
rather good to me.

Hope you understand.

The most easy way is to buy a device that can read a barcode and that you can connect to your computer. Otherwise, you will have to make your own reader.
Then you can read out your hardware port with software, or when you are lucky, a driver is provided with the reader.
Anyway, your reader should come with documentation about what the reader returns, signals and stuff.
If you make your own reader, you can define it as you want.
