What is a Barcode

The barcode is present in every product that you buy today. Therefore, it is very essential to ensure to understand what barcode actually stands for and what is its use in the marketing section.

A barcode is a sequence of lines of different thickness which are printed on the product in a parallel series, having a numeric code below or above the lines. Barcodes are printed on the paper or implanted on the products and can only be read by a barcode reader or a scanner. A barcode reader releases a specific light frequency. When this light is given over the barcode, the sequence of numeric value which is embedded on the barcode is displayed to the scanner, which than changes the input data into numbers and sends this information to the computer. Barcode software is used to change the data code into product information.

Any data which is related to this code is to be found by the barcode software. This type of information involve the product price, name, date created, weight, issuer, manufacture and receiver. Reduction in the price of computer processor and memory has increased the difficulty of the information available for the barcode. The principle of a barcode is to quickly take the detailed information of the product through a specific key number. The amounts of information that are related with the barcode are limited with the software used.

This type of contract increases the approval rate of technology and improves the excellence of the system and also maintaining the lower cost. An example of this type of corporation is Universal Product Code (UPC). In the grocery store industry, the UPC was developed into an 11 digit code in 1970s, in turn to identify any product. But still wide acceptance of this project was quiet slow. The high cost of scanners and many other issues makes this difficult. These systems today are used in a proper way and maintain the relational database of suppliers, sales activity, inventory levels, cost and increasing efficiency.

Different companies’ barcodes uses different types of bar combinations and numbers. Some of the larger manufacture uses longer numbers, but this depends on how many numbers are listed. Every number present in the barcode has a meaning. For example, if the number in the barcode starts with the a 0, than it is known as standard UPC number, and if the numbers begins with 1, than it is called as random-weight item, meaning that the product depends upon its weight, and if the number begins with 3, than it is pharmaceutical. There are many variation of this numbers, and each one represents something different.
