What is a barcode you may ask.

A barcode is an optical machine readable representation of data, which shows data about the object to which it attaches. Originally barcodes represented data by varying the widths and spacings of parallel lines, and therefore were referred to as linear or one-dimensional (1D). Later they evolved into rectangles, dots, hexagons and other geometric patterns in two dimensions (2D).

So how do barcodes work?

A barcode is simply machine readable language. The bar code is a set of lines and spaces that represents a set of characters. These characters can be alphabetic or numeric depending on the type of bar code used. Below are some individual letters and characters.
