A barcode is an optical machine-readable representation of data which is capable of presenting certain data of the products while a barcode system is a network of hardware and software, mostly consisting of mobile computers, printers , handheld scanners , infrastructure, and supporting software. Barcode systems are used to automate the process of data collection where traditional hand recording is neither time consuming or cost effective.
Major Group of Barcode:
Barcode which consist of sequence of printed lines, or bars, and intervening spaces. In the case of a UPC (Universal Product Code), the barcode contains the manufacturer ID number and the item number. Barcode data is determined by specification of number and width of the spaces of the lines. The UPC allows a cash register and a barcode reader to interpret the linear barcodes.
It is a graphical image that stores information both horizontally and vertically and thus can store up to 7,089 characters. 2D barcodes are also known as quick response codes because they enable fast data access. 2D barcodes are often used in conjunction with smart phones. The barcode reader which equipped in the phones interprets the encoded URL, which directs the browser to the relevant information on a Web site. This capability has made 2D barcodes useful for mobile marketing. Some 2D barcode systems also deliver information in a message for users without Web access.
3D barcodes use the same basic principle as linear and 2D barcodes. An image of some sort is applied to a product and then read by a device to log, categorize, inventory, or track an individual product. During manufacturing process, the 3D barcode is engraved or applied to the product itself. The 3D barcodes make it nearly impossible to alter or obstruct the barcode’s information and results in fewer inventory mistakes and in turn lowers operating costs of a manufacturing process.
