Barcodes are a graphic representation of specific characters through a combination of dark and light elements, determined according to the adopted rules for the structure of a given code (symbolism). There are data encoding characters and auxiliary characters specific to a given symbology. Symbolism is a description of the rules for creating particular types of codes, i.e. the way in which the characters of the handwriting, readable visually, are represented by light and dark elements of different width.
A bar code symbol is a set of elements whose structure results from a given symbolism and from visually legible characters presented graphically. EAN Barcode India allows automatic identification. Objects are identified without direct human intervention. This technique has been used in the world for several decades. Bar codes are the most common way of identifying and marking data today.
Markings like barcodes appear to be very complicated, but perversely they are the easiest way to catalog products. Today’s article will help you understand how they are built and why. At the end of each barcode, there is a check digit, which is responsible for the correctness of scanning. It allows you to diagnose, for example, a print or data transfer error. Analyzing the above information, it can be noticed that the number of digits in a bar code depends on many factors.
Applications of Bar codes
A barcode is a graphical representation of information about a product. The product barcode is designed for electronic readers. Its purpose is to enable automatic reading of information. The main application of the bar code is the automatic identification of products in broadly understood logistics.
The use of barcodes is becoming more common. Bar codes ensure fast, easy, and error-free data entry. Suitable for the application and use of codes increases the efficiency of the company’s operations. Assortment states can be registered to the program directly in the warehouse. The terminal can be placed on a trolley and scanned with a barcode reader according to the EAN13 code. Barcodes have many advantages that translate into a set of good practices from hundreds of companies. First of all, they are a carrier of information (indexing) – both consecutive document numbers as well as appropriate designations of the system operator, office/branch (if there are several in the company), etc. When encountering a barcode, scanning applications recognize a new document, which means that the operator can place 60-80 sheets in the feeder of the desk scanner.
How to generate a barcode?
In the age of the Internet, barcode generators are relatively easy to find. However, not all of them meet stringent international standards. So how do you get a barcode? First of all, thanks to specialized software that will take care of such elements as the presence of a check digit or the height and thickness of the stripes in the code. This technology is used primarily by specialized companies in the printing and self-identification industries. In the case of small-sized goods that do not contain EAN-13, the EAN-8 bar code is used.
