50 years ago, on April 3, 1973, IBM introduced the Universal Product Code linear bar coding technology. Now barcodes are used almost everywhere: in stores and warehouses, in medical laboratories and at the post office, at rental offices and in transport. What is hidden behind the barcode and how to decipher it – in the material “Kommersant”.
Stores use barcodes to track inventory, reduce checkout queues, and prevent store theft. The barcode first appeared on Juicy Fruit chewing gum. The stickers were applied in a supermarket in Troy, Ohio, United States, in June 1974. The tutu is now in the Smithsonian Institution’s Museum of American History.
The first three digits indicate the country in which the product was released. Behind the next four digits is the registration number of the manufacturing company. It is assigned by a special regional organization. Another five digits is the product code. It is invented by the manufacturer or seller himself. The last digit of the barcode is considered a verification digit. It can be used to detect fakes.
The modern barcode contains information about the country of origin, the manufacturing company and technical characteristics – name, article number, color, weight and size. Some of this information is read only with the help of scanners, some can be calculated “by eye”.
