The following data is encrypted into digital values (read from left to right):
- Producer country codes. At the same time, some of the codes are not found in trade, but are used only within the organization, and are also used for printed publications. All other values are those by which you can recognize the country.
- Manufacturer's registration number.
- Product code.
- The check mark for scanner verification and online verification is also used to decipher the code manually.
- Optional free field.

There are cases when a country code is indicated that does not correspond to the manufacturer:
- the goods are manufactured at a subsidiary located in another country;
- the manufacturer is registered in one country, and the release of goods is organized outside it;
- the goods are manufactured unofficially.
In order to check the originality of the product, you can use a certain calculation.
Consider the barcode 4814723005800. You can check the code for authenticity using simple arithmetic operations:
- Plus the numbers in even positions: 8+4+2+0+5+0=19
- The result is multiplied by three: 19 × 3 = 57
- We determine the sum of all the numbers indicated in odd places. The control sign (last) does not need to be counted: 4+1+7+3+0+8=23
- Adding 2 sums: 57+23=80
- From the last number (80) we select the last digit, that is, 0.
- Subtract the found figure from 10: 10-0=10. Authentication is based on this last digit 0.
- The resulting total digit must be equal to the last check digit in the barcode: 0=0.
If subtracting from 10 results in a single number, then it is the final number, by which you can check whether the barcode is legal.

Who Invented the Barcode

In 1948, Bernard Silver, while a student at an institute in Philadelphia, learned of a request from the president of a local food chain to develop a system to control a product with certain data about it. Silver pitched the idea to his friends Norman Joseph Woodland and Jordin Johanson. They started working on the project. The first operating system was based on the use of expensive UV inks. Later it became clear that they quickly fade. Woodland was confident that the system could be implemented and continued to work on it.
The following solution was based on Morse code. Dots and dashes stretched into strokes and merged into code.
In order to recognize strokes, he used optical sound recording technology for the film industry. The request for funding for the development of the system was refused by IBM. About a year later, on October 7, 1952, Silver and Woodland received a patent for the invention. The patent was later sold to Philco, who resold it to RCA. The first item the store sold by number was chewing gum from Wrigley.
