Solution

The correct option is A Bar code

Codes consisting of light and dark marks which may be optically read is known as Bar code.

A bar code (often seen as a single word, barcode) is the small image of lines (bars) and spaces that is affixed to retail store items, identification cards, and postal mail to identify a particular product number, person, or location.

Barcode scanners can be extremely simple devices made up of a light source, a photo diode and a simple decoder or complex CCD or camera based scanners. Learn how barcode scanners work and how to scan barcodes into a computer. Each uses a slightly different technology for reading and decoding a barcode.

Contains a very limited amount of data. It is typically just an identifier on a database of that particular product. In the case of UPC codes there is a standardized database so your code is assigned to you for each product. In 2D and larger barcodes you can pretty much put in whatever information you like.
