A barcode is an optical machine-readable image of a data. It initially symbolizes data in the spacing and the widths of parallel lines. It can also be referred to as linear or one dimensional symbologies.



The first application of barcodes was to mechanize grocery checkout systems. It has become more or less universal today. Their application has extended to numerous other functions as well. These are generally referred to as Auto ID Data Capture.

Barcodes work on the principle of optical technology. The label is scanned on the device and reads the code. There is also a program you can install to scan these codes. In Japan, the majority of cell phones have integrated scanning software.

Ever since their creation in the twentieth century, barcodes have gradually become a vital part of the modern business world. Their application is extensive. The technology behind it is continuously improving. A number of its modern uses include maintaining track of the huge figure of items in a store. It also decreases cases of shoplifting.

Printing barcodes

To be able to print barcodes on to a product the user will need a barcode printer. A barcode printer is a computer accessory made especially to print labels that could be read by a barcode. After printing, it can now be attached to objects. It is most commonly seen in cartons about to be shipped, or in retail items like books, gadgets and apparels.

The majority of printers use one of two special printing technologies. First is the direct thermal printer that makes use of a printhead to create heat. It chemically reacts in a special paper that creates those lines and bars we normally see. The heat generated makes a paper turn black. Thermal transfer printers also use heat, only in a different way. The heat soften a resin or waxy like substance on a ribbon that runs on top of the tag or label material.

The heat liquidizes the ink from the ribbon and transfers it to the special paper. These are generally cheaper, but they make labels that can become unreadable if exposed to direct sunlight, heat, or chemical vapors.

Many different businesses use such printers, like the huge warehouses and manufacturing plants. They can operate faster, have big paper capacities and lasts for much longer. The desktop barcode printers are most prevalent in the retail outlets and other related shops.

It has greatly improved the retail system. You would hardly see long queues in the cashier anymore because of this new technology. Inquiries have also been made much easier in the customer service booth. It takes only a second of scanning the barcode for the complete details to show in the computer.
