A barcode is a machine-readable representation of data that describes the object it is attached to. There are two different types of barcodes, 1 dimension and 2 dimension. 1 dimension barcodes hold the data for specific objects in the width and spacing of the parallel lines and can only be scanned vertically. These barcodes are commonly used in retail tags and grocery packaging. The first three digits of a 1D barcode identify the product manufacturers and their country of origin and are referred to as the company prefix. 1 dimension barcodes have an 85 character limit and do not support attributes. Unlike 1 dimensional barcodes, 2 dimension barcodes can hold hundreds of characters. 2D barcodes can hold a lot of information and remain legible even when printed at a small size or etched onto a product giving them the ability to mark very small items. 2D barcodes are used in a wide range of industries such as manufacturing, warehousing, logistics, and healthcare. These barcodes are not limited to text, they can contain images, websites, music and more. The first barcode ever scanned was a UPC code on a 10-pack of Wrigley’s Juicy Fruit Gum at a grocery store in 1974. Both types of barcodes can be scanned by Zebra Technology devices such as scanners, mobile computers, and tablets. There are over 5 billion barcodes scanned daily and they have created a new way of doing business by enabling flawless interaction with products from around the world.
