It is the name given to the symbol formed by long and short black bars consisting of lines of different thickness drawn in a rectangular shape, parallel to and the spaces between these lines. Barcodes allow data to be transferred from one environment to another automatically and without error.
Many information such as product stock codes such as reference numbers can be easily accessed via barcodes. Barcodes enable this information to be entered into the computer environment in a much faster and healthier way than manually.
It started to be developed by Bernand Silver in 1940 to quickly register the products of an American supermarket chain. The system developed by Bernand emerged with a method similar to Morse code. Later, this system gave way to thin lines. This method, which is still used today, is the most widely used barcode system.
What Do the Lines on the Barcode Mean?
Barcodes consist of lines and spaces of different thickness. The black lines on the barcodes indicate the number 1 and the spaces on the barcodes indicate the number 0. The meanings of the lines vary according to their thickness. The thinnest black line denotes one unit (1), while the thickest black line denotes four units (1111).
The same is true for spaces as in lines. The narrowest space is one unit (0), the widest space is four units (0000).
The most widely used and best known barcode type in our country is the EAN - 13 barcode. This barcode consists of 13 digits. The first of these numbers divided into 4 parts consists of 3 numbers. The first part shows the country or symbol code. This code varies from country to country. Each country has its own codes.
The second part shows the firm code. This part consists of 4 numbers. The third part consists of 5 numbers and is used for product promotion. The last digit is for the fourth part. This section is created as a result of calculations so that the barcode can be read correctly.
