Bar codes are located on any item you purchase these days at supermarkets or shopping malls. All the stuff, from the hugest washing machine to a packet of chocolates, has this special set of symbols that distinguishes it away from all similar merchandise.

Height, width and spacing of the bars within the bar code are all symbols for what they actually represent. Depending on the types of symbols that are used in the code, each bar represents a type of data, whether it be numbers or alphabets.

Photo devices in the symbol scanners translate the bars into electric signals which can then be “read”.

The electrical signals become readable when specific software is used for converting them, and the way that the code is written is based on how tall the bars are or how spaced apart they may be.
