We often see some black and white straight strips on the packaging of goods

That's the commodity identification code, every commodity has it, and every commodity will be entered into the computer, so we can only take things away after we buy something, after checking out, the cashier recognizes the identification code on it.

This so-called black and white barcode is called a barcode, and we can identify various information about the product through the barcode of the product.

When we buy any product, as long as the product meets the normal product specifications, there will be a barcode on the back of the product. There will be differences in the subdivision of the barcode of different types of goods, but because the barcode itself has a fixed specification, we can distinguish all kinds of information of the signboard code by scanning the barcode of the product, and the barcode of all goods is unique.

1. The official name of this barcode is the meaning of barcode.

Behind the outer packaging of the product, each package will have a fixed barcode, through which we can judge the basic information of the product. When we scan the barcode through a special instrument, the back of the barcode will not only indicate the productivity of the product, but also the manufacturer and product name, as well as the production date and postal information. <>

2. All regular goods will have a barcode.

In modern society, all goods sold in the market need to have a barcode, and this barcode is also more common for us to be able to distinguish whether the goods are legitimate. Although some products are sold in bulk, there will also be a fixed barcode on the total packaging of the goods sold in bulk. At the bottom of the barcode, we can also see the permutations and combinations of numbers, which can be simply understood as supplementary information to the barcode.

3. There are slight differences between barcodes and ***.

For consumers, consumers often use the best of various goods, and when making payments, some stores also support the payment by scanning the code. For manufacturers and sellers, the industrial end of the *** will generally be replaced by a barcode, this barcode is also a fixed mark of related goods, merchants and factories will identify the details of the item through the barcode and the number behind it, so as to manage and store the item. <>

That's a barcode, also known as a product identification number. Each item has this barcode. It is used to query the manufacturer and **.

That's the barcode, mainly used in supermarkets or stores to facilitate the scanning of the code and enter **, so that the goods selected by the customer can appear on the computer and then proceed to the follow-up checkout.

The barcode of the product.

In fact, every product has such a black and white or other color bar, that is, the product identification code. The product identification code is like people's ID card, representing the identity of the product. You may also notice that under these black and white bars, there is also a set of numbers.

When the merchant buys the goods, this set of numbers is entered into the computer, and then the computer has a memory and can identify the ** of the product. As long as the cashier scans the barcode with the barcode scanner, the item will be displayed on the cash register**.

The product barcode is the ID card of the product.

The product barcode is developed by the International Article Number Association, which is not repeated and unique in the world. There is only one single item of a product**. Different specifications, different packaging, different **, different tastes, different colors, as long as it is not the same product, different barcodes must be used.

Just like us humans, no matter how tall, short, fat or thin, even if they are twins, they can't use the same ID card. <>

An integral part of a product's barcode.

The barcode we use today is a universal commodity barcode, which is also the most widely used barcode in the world. In order to be able to achieve the uniqueness of the commodity, the bar code is basically composed of several parts: country or region** + manufacturer ** + product ** + check code.

For example, in the barcode of 6901234567892, 690 represents the country**, 1234 represents the manufacturer**, 56789 represents the product**, and 2 represents the check code. <>

What are some of the black and white strips of paper that we often see on product packaging?

As I briefly mentioned earlier, the black and white straight strips on the packaging of the goods are actually the identification codes of the goods. In order to distinguish it from other goods, it represents the uniqueness of the product. Today's barcodes are basically made up of 13 digits. <>
