Simply indispensable in modern companies: the barcode

Nowadays, barcodes are part of classic everyday life almost everywhere in the world. The small-format codes have been found on most supermarket items for decades, among other things. But how does a barcode actually work exactly? We explain how the small data storage devices work.Structure and functioning of a barcodeA barcode is an encoding consisting of bars and bars and can be found on most products in the retail trade. The barcode stores important product information, which can then be read using a barcode scanner.

Most supermarket checkouts, for example, have such a scanner. The scanner reads the name, the article number and the price of a product at the checkout, and this information can then also be seen on the receipt. But barcodes can do much more. For example, companies can use them to automate their warehousing, optimize business processes and track the shipment of goods.

Even ID cards and event tickets can be verified quickly and easily by means of an imprinted barcode.Meanwhile, barcodes can be read with a normal smartphone if a corresponding barcode scanner app has been installed on the mobile phone. Consumers can thus find out about a product's ingredients and check where a particular food was produced, among other things.Different types of barcodesDepending on the type of use, a distinction is made between different barcode types. The best known European barcode is the EAN 13, which stands for "European Article Number". The code consists of 13 positions, the last digit is a check digit.

EAN codes are mainly used for product identification. Other common barcodes include the GS1 DataBar, which can have up to 74 numeric and 41 alphanumeric characters. This particular barcode is primarily used for storing complex information, such as weight or best-before date. The so-called QR code is also becoming increasingly popular.

The 2D barcode was developed in Japan in 1994, the abbreviation QR stands for "Quick Response".The advantages of barcode useCompared to manual data entry, two major advantages of a barcode are obvious: With the barcode, things simply go faster and typing errors are eliminated right from the start. Data capture is often completely automatic, especially in logistics. A barcode usually only has to be printed once on a product. Changes to product data, such as price, are made in the merchandise management system and are irrelevant to the information on the barcode.First own steps with the barcodeThe arguments for the operational use of barcodes are clearly convincing.

Therefore, more and more small and medium-sized entrepreneurs dare to take their first own steps with the use of barcodes. A free barcode generator is an excellent way to create and try out a barcode. In addition to your own email address, you only need to enter the information that is to be stored in the barcode. The internet tool saves this information and sends the code immediately by email.

The finished barcode can then be printed on a product, but also on business stationery or on your own website.
