Welcome to barcodenepal
A bar code is simply a set of symbols used to represent alpha-numeric information. Basically, instead of seing the number "1", or the letter "A", you would see a series of bars, both fat and thin, used to represent that number.
So, why replace the alpha-numeric characters with a bar code in the first place, you might ask. Humans can easily determine that a strange combinations of lines and curves and dots are put together to form a letter or number, but computers aren't as quick in deciphering such information. Even though Optical Character Recognition has come a long way in recent years, it's much quicker and much more accurate for a mechanical device to decode and series of black and white lines than it is to read human text.
