What is a barcode?

The barcode is a number of rows of different thickness of printed in a parallel sequence, with a numeric code above or under guidance. The barcodes are printed on paper or inserted into the product and can only be read by a scanner or barcode reader. When this light is directed to a barcode, a number of numeric values ​​that are inserted into the code are displayed in the scanner, which then converts these input data into numbers and sends this information to a computer processor. Barcode software is used to convert code to product information.

Any data linked to this code is located software. This information may include product name, price, weight, production, created date, issuer and receiver. Reducing the price of computer and processor memory has increased the sophistication of information available from the barcode.

The purpose of the barcode is to allow a computer tracking system to quickly pick up detailed product information via a single key or barcode number. The amount of information that ktEré can be connected to a barcode, only the software used is limited. There are certain standards in various industries for which field information and names will be provided.

This type of agreement increases the adoption rate of technology and increases the quality of systems while maintaining lower costs. An example of this type of cooperation is the universal product code (UPC). UPC was developed into a standard 11 -digit code in the middle of the 70s in the mid -70s to identify any product.

The wide acceptance of the project was slow. The high costs of locating scanners at each cash register and the need to move to centralized computer systems often outweigh the benefits. These systems are now used for proper monitoring and maintain of the relational database of costs, suppliers, inventory levels and sales activities, increasing efficiency.

in a wide range of industries exists nAt least 15 different types of barcode standards. Libraries, postal offices, manufacturers and ticket systems have all received a barcode as a reliable, cost -effective way of monitoring the product. Each industry has set up its own standard coding sequence.

New technology extends the amount of data that can be coded in a barcode and now contain numeric codes and symbols of alpha. The first barcode patent was released in October 1949 by Norman Woodland and Bernard Silver for the classification apparatus and method. This patent included printing formulas and technology needed to read code.
