BARCODE?

According to wikipedia, a barcode (also bar code) is an optical, machine-readable representation of data; the data usually describes something about the object that carries the barcode. Traditional barcodes systematically represent data by varying the widths and spacings of parallel lines, and may be referred to as linear or one-dimensional (1D).

The pattern or combination consists of black and white bars (elements) represents different text characters which follows a set algorithm for that particular barcode.

 Every product has a unique barcode all over the world. Barcode contains information about a product like; date of manufacturing and expiry price, weight of the product, name of the manufacturer etc. Barcode is allocated by an international institution set up for this purpose.

There are two types of Barcodes
