A barcode consists of dashes and gaps in different widths. Due to this construction, it is often referred to as bar code. The coded information of this simple graphic can be read out with the corresponding reader. Nothing else, for example, the scanners, which probably everyone from the checkout in the supermarket should know.
The idea behind it is not new. The first attempts were already made at the end of the 1940s. With the introduction of UPC and EAN, barcodes have become increasingly important and have become increasingly widespread. Today, they are an integral part of any product that is commercially available.
Application and advantages
Barcodes play an important role in the trade of goods. They are used to encrypt the various item numbers (UPC or EAN codes, respectively since 2009 the Global Trade Item Number). Barcodes have some decisive advantages. Important is the significantly faster handling, which makes them possible. Without a barcode, for example, the article number should be typed in the supermarket for each individual product, or the item including the price entered. Instead, the goods can be easily scanned. This saves time and also reduces the error rate, as typing errors can be excluded. Of course the advantages are not limited to the trade. Storage is also greatly simplified by the possibility of scanning. After all, the goods need to be scanned here, both at the input and the output, so that it is always apparent how high the current stock of a particular product is.
Create barcode online
In order for the whole thing to work, it is first of all necessary to generate the appropriate code. The right tool for this purpose is a bar code generator. For example, the ISBN or EAN number is entered and converted into the correct sequence of strokes. The generated online barcode can then be saved and printed. This can take place in the form of labels with which the goods are labeled. However, at least in the case of larger companies, it is customary that the bar code including the number is printed directly on the packaging.
