Особая маркировка на товарах в виде штрих-кода familiar to everyone, but not everyone knows how to extract information from it. Meanwhile, it serves as the carrier of all important information about the products and is the main assistant in the accounting of goods sold by any trading enterprise.
Who came up with a barcode
The idea of creating a code containing basic information about the product belongs to Bernard Sylver, a graduate student at Drexel University of Philadelphia.
Having tried all sorts of marking methods, heHe dwelt on a method involving the use of ultraviolet ink. The technology turned out to be imperfect - the use of such ink was financially costly, and over time they turned pale and soon disappeared completely.
The impetus to the creation of a bar code became Morse code, Silver transformed the points and dashes into lines, having received a better method of marking.
Barcode appeared in 1949, but the lack of special equipment for reading information prevented the timely implementation of development in various industries. For encoding information about the product, it began to be used 10 years later, when computers and laser equipment appeared.
Initially, the barcode was oval, and the first product sold by scanning information from it was Wrigley chewing gum (1974).
Barcode Encrypted Information
Today, almost all productshas its own unique code. The manufacturer reserves the right not to put it on goods, but in this case, their implementation will be difficult or not at all - the vast majority of outlets do not accept products without a bar code.
It encrypts the following information:
- producing country;
- manufacturer;
- product code.
How to decode a barcode
The European Standard Barcode (EAN) has 13figures, less often - 8 (applied on packages of very small sizes), ITF system has 14 figures. Each digit is encoded with strokes and spaces to read information by the device.
The first 2 or 3 digits are the country code where the product was manufactured. The most common codes are:
- 30 - 37 - France;
- 45 - 49 - Japan;
- 50 - United Kingdom;
- 84 - Spain;
- 400-440 - Germany;
- 460 - 469 - Russia;
- 690 - China;
- 481 - Belarus;
- 890 - India.
The following 5 digits are assigned by the authorized body of each country to the manufacturer.
Цифры, за исключением последней, являются кодом product, which is set by the manufacturer. These numbers contain identification data - name, article, grade, size, color, weight, etc.
The last digit of the code is the control one, with its help the authenticity of the application and, accordingly, the product is verified.
How to verify the authenticity of the goods using a barcode
Barcoding products and products significantlysimplifies the work of manufacturers, logistics companies, retail outlets. In addition, each person can check the goods for authenticity by arithmetic calculations using the numbers printed on the bar code.
It is important to understand that this method does not have a 100% guarantee, since it is possible to place a counterfeit product or food product in the original primary packaging.
The calculation sequence is the following (the check digit is never taken into account):
- add together all the numbers that are in even places;
- multiply the result by 3;
- add numbers to odd places;
- add together the results obtained in the two previous actions;
- delete the first digit from the amount;
- subtract 10 from the last result.
Products are considered original if the result of the calculation corresponds to the check digit.
Example - product with barcode 8904091116621:
- I + 4 + I + 1 + 6 + 2 = 31;
- 31 x 3 = 93;
- 8 + 0 + 0 + 1 + 1 + 6 = 16;
- 93 + 16 = 109;
- the first digit is removed from the result, it turns out 09, i.e. 9;
- 10 - i = 1.
The number 1 corresponds to the check digit, this gives grounds to assume that the product is original.
How is the reading of information
Today, barcode technology allows you to encrypt a large amount of information, and bar codes are increasingly applied to products in the form of smaller matrices.
Organizations involved in transportation, acceptance andsales of products put it on the account in the program barcoding products. For maximum control of their movement, up to the sale to the end user, a computer and a laser scanner are used.
Laser beams, hitting the bar code, fixchanges in the reflected light. Information about these changes comes to the computer in the form of characters encrypted in a barcode. A comparison of the received characters with those available in the database is launched. When an exact match is found, information is displayed on the screen.
Bar-coding of goods allows you to get the necessary information for a fraction of a second, which greatly simplifies the process of moving them.
Barcode products in 1C
Some organizations prefer to useown system of bar-coding of goods for the convenience of tracking their internal movement. In addition, upon acceptance, the integrity of the package may be compromised, making the scanning process impossible. In this case, creating your own barcode is a must.
So that the reading process does not slow down, it is advisable to use unique codes.
In the 1C: 8.2 program, barcoding of goods is carried out in the nomenclature cards. Barcodes are displayed in all tabular parts in the “Products” tab, in the nomenclature list.
If for some reason the information from the barcode is not read by the scanner, it is possible to enter it manually using the commands “Enter barcode” or “Barcode search”.
Barcode retail merchandise
The use of bar-coding products in retail stores will assist in many ways:
- implementation;
- accounting for movement within the outlet (for example, from a warehouse to a trading floor);
- pricing;
- establishment of a discount system.
For the successful implementation of the automatic information reading process, you need to configure the necessary parameters in the 1C system and purchase equipment.
Program settings are changed in the tabs: “Store”, “Warehouses”, “Goods”, “Prices”, “Discounts”, “Access Rights”.
The necessary equipment for work are:
- scanner - wired or wireless, for a small retail store you will need one hand scanner;
- fiscal registrar - stores information in memory and prints checks, its operation is controlled by software installed on the computer;
- label printer - for the point where new price tags are often printed, small thermal printers are suitable.
Today, the use of barcodes allows in a short time to get all the important information about any product and to carry out the process of its movement as quickly as possible.
