Step 1

Two types of barcodes are most commonly encountered: European 13-digit and American 12-digit. They are fully compatible with each other. Let us dwell on the first of them in more detail. In such a barcode, the first three digits are the country code, the next four are the manufacturer's code, the next 5 are the product code (they contain the product name, its consumer properties, dimensions, weight and color) and, finally, the last digit is called the control one. It is used to check the correctness of the code.

Step 2

A barcode by itself cannot guarantee the quality of a product, but at the same time it is an authenticity marker, since any officially registered product has its own unique number.

There is one interesting method of checking a barcode, as they say, in the field.

Let's say we have some kind of barcode. We take (counting from left to right) and add the numbers in even places. The resulting sum must be multiplied by 3. Next, add up all the numbers in odd places (we do not take the check digit). It turned out two sums. We add them up. In the resulting number, we discard the tens place and subtract 10 from what remains after this discarding. If the result is a check digit, then the barcode is genuine.
