What is a barcode? What does barcode mean

It is the bar code s in the grid in the vertical stripe interval is scanned after the computer preset information, such as shopping in the supermarket, after the weighing will automatically print out the barcode, which contains the product name and**, and the barcode is set in the computer when the merchant buys, for example, the first few represent the product name, the last few represent the price, so no matter how many varieties will not be mistaken.

It is the machine that can be recognized, recording the origin of the country, whether it is eaten or used, how much weight it is, what type of packaging, ** labeling and so on.

After all, it is impossible for the computer to recognize Chinese characters and letters, and if they are manually typed by the salesperson, it will be very slow, so the role of the barcode will come out.

For example, if you go to the supermarket to buy something, the cashier uses the scanned thing to take a picture of the barcode, and the price or something is displayed on the computer, and the barcode is the barcode, but it is only one of the barcodes.

A barcode is like an ID card for an item.

That's the ID card of the product, such as the barcode on the back of the book. Those are a column of numbers provided by the National Press and Publication Administration, and then generated by a barcode upgrader, and a column of numbers corresponds to only one barcode.

It is the back of the product with some black bars of different thicknesses...

Now all commodities, as long as they need to enter the market circulation, they need to add commodity barcodes to the product packaging.

This commodity barcode is generally 13 digits of data ean13 barcode type, the first 12 bits can be written by yourself, the last digit is the check code automatically generated by the software, then if the amount is more, you need to generate in batches, you can save the data in excel, and then use professional barcode software to make. Here's how;

First, place the barcode.

The data is saved in Excel, the first row is the column name, not the barcode data, and then arranged in the order of printing, and the cell attribute is better to be "text type":

2. Open the barcode software to create a new label and import the product barcode data into the barcode software Double-click to open the Zhonglang barcode software, create a new label paper according to the actual size of the label paper, and set the actual paper size and layout parameters;

Then click the "Database Settings" icon in the upper toolbar, click "Add" to select the corresponding type of database according to the prompts, and then click Browse to import the Excel data file and click "Test Connection" to load the data

3. Draw a barcode and add variable data Click the "Barcode" icon in the left toolbar, draw a barcode style on the canvas, and double-click to open its "Barcode" window, and modify the default barcode type to EAN13 product barcode:

After <> product barcode data is added, you can see the check code that has been automatically generated, the barcode display data is one more check digit data than the original data in excel, after the product barcode data is added, you can click the print preview button in the upper toolbar to view the preview effect, you can turn the page to view, you can click the icon after checking, and connect the printer to print in batches:

Barcodes are a must-have for today's goods, and now it is difficult to circulate in the market without barcodes! Barcodes are required both online and offline. Having a barcode is equivalent to having an ID card.

Each barcode represents all the information of the product, such as **, raw materials, origin, etc.!

Barcode is a kind of data input computer that uses photoelectric scanning and reading equipment. It is a set of bars and empty symbols arranged according to certain coding rules, implying certain characters, numbers and symbol information, which is used to indicate the name, place of origin, **, type, etc. of the article. "Bar" refers to the part with low reflectivity to light, and "empty" refers to the part with high light emissivity. As shown in Fig

There's another thing upstairs that doesn't add upstairs. In fact, there are 13 digits in the barcode. The first three digits of the barcode are the country of the product** and also represent the quality of the product in the country.

China's ** is 690 695, the closer to 690, the better the quality of the product (such as 690 is better than 691, 695 is the worst.) It is worth noting that this barcode is limited to China, and the barcode of foreign products is counted separately). The fourth to eighth places refer to the manufacturer's **.

The ninth to twelfth place is the product in the factory (you can take a look, such as Hengan Group's products, paper towels and other daily necessities manufacturers**, the products ** are different). The thirteenth digit is the check digit, which is calculated from the first twelve digits according to a certain algorithm.

To put it simply, barcodes have the following advantages:

Barcodes are by far the most economical and practical form of automatic identification technology.

a Fast input speed: Compared with keyboard input, barcode input is 5 times faster than keyboard input, and "instant data entry" can be realized.

b High reliability: the error rate of keyboard input data is 1 in 300%, the error rate of optical character recognition technology is 1 in 10,000, and the error rate of barcode technology is less than 1 in 1 million.

c. Large amount of information collection: the traditional one-dimensional barcode can collect information of dozens of characters at a time, and the two-dimensional barcode can carry thousands of characters of information, and has a certain automatic error correction ability.

D Flexible and practical: barcode identification can be used alone as a means of identification, and can also be used with relevant identification equipment to form a system to achieve automatic identification, and can also be connected with other control equipment to achieve automatic management. In addition, barcode labels are easy to make, there are no special requirements for equipment and materials, identification equipment is easy to operate, no special training is required, and the equipment is relatively inexpensive.

e.The cost is very low. In the retail sector, the cost of barcodes is almost 'zero' because they are printed on the packaging of goods.

Of course, now goods all over the world are inseparable from barcodes, which facilitate our lives and are indispensable in our lives.

Barcode technology is an automatic identification technology that is widely used in commerce, postal services, book management, warehousing, industrial production process control, transportation, packaging, distribution and other fields.

It first appeared in the 40s of the 20th century, and is "composed of a set of regularly arranged bars, spaces and their corresponding characters to represent a certain information". The automatic barcode identification system consists of a barcode label, a barcode generation device, a barcode reader, and a computer.

Barcode technology, which is a new technology that integrates coding, identification, data acquisition and processing. In order to enable the free and extensive circulation of goods in the world, enterprises must follow the relevant regulations of commodity bar code management, whether it is design and production, apply for registration or use commodity barcode.
