A bar code consists of a series of parallel, adjacent bars and spaces.
Predefined bar and space patterns or “symbologies’ are used to
encode small strings of character data into a printed symbol.
Barcodes can be thought of as a printed type of the Morse code
with narrow bars (and spaces) representing dots, and wide bars
