Bar Code Technologies is the best technology for contactless identification. At the conclusion of her for an effective regimen of material values ​​of the skin product, assign a unique code and will not be able to read it at the smallest pardons.

Boulo was discovered by American engineer David Collins in the 1950s.

A barcode is a symbol that can be stored from a small smog (strokes) and space between them (glades), which displays the machine code of letters and numbers in two systems.

Dash (smuga) - a dark area of ​​the image on a monochromatic light aphid, surrounded by straight parallel lines or concentric stakes. elements barcode to be applied to the surface of the nose, which has excellent light-technical characteristics. At the same time, strokes should be applied for the help of the barvniks, as if they were others, kindly glaze the light on on the date of the dinner hvil, and the background surface is kindly imagined, so and vikorystovuyutsya with optical reading.

Skip-space with strokes. For a large number of codes in the width of the probe, there is a single information, if there are no probes in any codes, there is an additional part of the image and the display of the function of the element-distributor.

Stroke coding. The barcodes have no lingering codes. The skin of them has its own powerful rules for the image of a symbol, tobto writing, order of words, punctuation marks, vimog for friend and decorating, conversions of pardons and other characteristics.

Rizni koduvannya is based on tributes, as well as types of tributes, as there may be mischief: deyaki code only numbers, іnshі - numbers, letters and deyak_ punctuation marks.

UPC code is a simple and practically symmetrical linear barcode. The code is stored in 2 groups of digits, 6 digits each in a skin group - left and right. The skin number of the left chi of the right group is codified behind the additional strokes: two lights and two dark ones. The skin stroke can be as wide as one, two, three or even one. First digit to code - tse so titles prefix - maє deyakiy logical, Ale is not important from a technical point of view. Remaining digit - check digit, to serve for detection mercy when reading the code by the scanner or manually entering numbers into the code from the keyboard.

There is no way to read the combination of strokes, the code is specially crafted, so it’s just as simple to read it in a straight line as it’s just to turn the product over. It is also not important that the entire barcode is displayed as photographic positive or negative. Tobto the barcode, applied by light smiles on a dark background, can be read absolutely like that by dark smiles on a light background. Moreover, the color of the strokes and the background is not necessarily guilty of being bilim and black, they can be combined with colors. UPC code reveals only numbers and any letters or some symbols.

EAN - European standard for bar code, signs for code identification of goods and virobnik. Є Bezlichchyu American UPC standard. Win є bezperervnim, I get a fix for dinner і high degree I can write down to display 13 digits from 0 to 9. The code value can be rotated (EAN-8) or thirteen (EAN-13) digits, moreover, 7 digits are coded in the first vipad, and in the other - only 12 digits, with a check sign є to confirm the correctness of the reading of the code. EAN barcode signs are stored in two strokes and two promises. Codes EAN-8 and EAN-13 include only numbers and some letters or symbols.

Vikoristannya barcodes EAN-13 would be handy, but not always possible. If the goods are small in size, then for the EAN-13 code you may not have enough space on the labels. Change the size of the code to a change in the width of the strokes. As the strokes will be overtaken, the separate building of the scanner may not be sufficient for reading the barcode. For the marketing of small products, the standard barcode is EAN-8, in the text of the sheet that only 8 digits are coded instead of 13. EAN-128 values ​​for the transmission of information about the vantage between industrial enterprises. Such a code can be revenge for information, For example, product code, terms of accessibility, rozmіri, obsyag, part code virobnik і in

15. Barcode formats: Code 39, Code 128. Structure, power, visual signs.

In Danish hour there are more than 50 barcode systems. Code 39: the first name is tied to the structure of the image of the signs "З з 9", three elements of the sign are from nine wide, and the width is high. Leather sign to the code of 39 representations with five strokes and with holes you can encode great Latin letters (from A to Z), numbers (from 0 to 9) and special symbols (for example, the dollar sign "$"). Code 39 discrete, controlled by name. The perevagoyu tsyogo code є. The structure of the Code 39 barcode is stored in six zones: Bile (vilny) field; Start symbol (Start); Coded information; Reversal symbol (check sum) - optional parameter; Zupinniy (Stop) symbol; Bile (vilny) field. A barcode to the Code 39 standard, on the form of Code 128, may not be a control character.

The Code 128 barcode standard is often derived from such widely expanded barcode standards, such as the EAN. Vіn can code not only numbers, but also letters of the Latin alphabet, but also special symbols. In addition, the digital code in the Code 128 format has become even more compact, it can be reached for the "sub-packaging" ranger, if two numbers are written into one module with a barcode. Lіternі symbols are encoded in a very special - "one-by-one" way, to rob the lіternіy code in the format Code 128 in the previous digital format. The structure of the Code 128 barcode is simple: Bile field; Start symbol (Start); Coded information; Reversal symbol (check mark); Zupinniy (Stop) symbol; Bile field. The specificity of Code 128 has a check mark binding. Code 128 symbolism is widely used for B2B deliveries to virobnits. Danish standard go for a zahalny zasosuvannya, for example, for marketing DVD-disks, dedicated to individuals and bagatokhs.

EAN-13 barcode (translated as European Article Number, plus a number of changes to International Article Number, if the EAN abbreviation is saved) - 13-digit (12 digits plus check digit) barcode standard, which is unavailable for the 12-digit UPC standard. 1970 by George Joseph Laurel. EAN-13 regulations for the organization of standardization EAN 13.

13 digits of the EAN-13 barcode are grouped with the following rank:

• Liva group: Figures 2-7. The liva group also includes the first figure, in which to lay down the reversal of the pairing.
• Group rights: Digits 8-13, 13th digit є control.

Barcodes EAN-13 to be sold in all goods The digits are encoded in the EAN-13 codes є international product numbers, in Japan as Japanese Article Numbers (JAN). All digits encoded in UPC and EAN barcodes, look like Global Trade Item Numbers (GTIN), stink can be encoded in other EAN barcodes.

structure

The GTIN-13 digits encoded in the barcode are stored from the following components:

The EAN prefix, the first three digits, call in to start, in the national organization of the EAN registration of the virobnik (you can not go to the place of the actual product).
If the ISBN is rewritten in EAN-13, the EAN prefix will be 978 or 979. The prefix 979 will be if the ISMN is rewritten (the same prefix for ISBN) and 977 for ISSN.

The code of the enterprise is used optionally only in quiet cases, it is necessary. Vin consists of 1-8 digits, in the presence of the number of GTIN-13, which is necessary for the virobnik for identifying new product lines (in the ISBN and ISSN standards, a component can be selected for the purpose of creating a video message) , deregistered ob'yazkovі specimens.Vіn last on subblocks for vіdavtsіv; Bagatіm regions in the ISSN and ISBN registries are seen by a number of prefіxіv.

The product code, which can be stored in 1-9 digits (in ISBN and ISSN, in the case of a unique identification of the publication from one and the same view; Seeing so і do not publish і do not go into sales).

check digit

The check digit is violated modulo 10 with wagons of 3 and 1. Zokrem, if all the numbers, multiplied by the wag of the series, last by 10 without surplus, the EAN system will detect all one-time pardons. However, if the difference is to go by the value - the guy is a number, the EAN system does not capture all the sums of permutation.
The second number is vikoristovuєtsya yak umovne code designated for joke information about the line of products, fixed in the database; tse number zvychayay not break on the components in your system.

prefixes EAN

First two or three digits of the GTIN, whether a product is to be used, a virobnik will be stored in the national organization of the EAN. It is necessary to note that the EAN-13 codes were quickly repaired from 0, so it’s just a larger form of 12-digit UPC, represented by the same barcode. However, the rest of the hour more and more goods, which are sold outside the United States and Canada, get EAN-13, which can be repaired from 0, so now the code looks like EAN-US.

Regional codes 200-299 Most EAN Organizational Members provide a wide range of internal victorian in razdrіbnіy trade (or all-in-between enterprises). activities of enterprises distribution trade vikoristovuyt yogo for vlastnyh (for the strongest trademark chi ni) goods trade marks); deyaki vikoristovoyt, shonaimensche, part of the prefix for goods, packed in stores, for example, you can speak at the checkout before selling customers. The size of the identifier for the product, the barcode can be used to explain the information about the price, the number of any goods (in the presence of the seller's account); The identifier for the product can be assigned by the EAN system administrator, or the values ​​itself can be used. Companies that traditionally used UPC barcodes, now switch to EAN prefixes: 04 (for goods) and 02 (for goods packaged in stores).

Check Digit Role

Before koduvannya check digit is counted after additional digits. Vona rozrakhovuє The control will be a figure, as it is necessary to add to the sum, the amount of money was 10 without surplus (this is a counter element for module 10). for more I will describe again For the algorithm see also ISBN check digit calculation. The Global Identification Number (GLN) is also a vicarious method.

Wiglyad yakє barcode?

stroke - ean code 13 visually viglyadaє yak a row of swarms of black and big smogs, supplemented with a set of Arabic numbers.

• The first 2-3 digits on the left side indicate the relevance to the specific country. Russia is assigned a range of 460-469.
• Step 4-5 symbols - the code of the virobnik for the company's product.
• The 5-digit code characterizes the non-middle item, being its unique number.
• Check digit.

Do not wait for a product that is rooted in a particular country, but only a barcode of the country itself. The legal and viral addresses of the company often do not get lost, the virobnik can be a daughter's company or a foreign branch and so on. Programs for generating bar codes ean 13 online

For quick otrimannya barcode є special services - online generator.

Yak pratsyuє online generator?

• A collection of koristuvachev will be used to vibrate bazhanu koduvannya, for example, EAN-13.
• Offensive croc - enter 12 digits, in which information will be encoded. I will stop, 13th, no need to enter the number, the program will be opened automatically.
• Stuck on the button "Create barcode"
• The readings of the generation will have an EAN-13 barcode, which is ready to be locked or saved in the required graphical format.

You can open the decal of barcodes one hour, writing numbers one to one.

Online generator is also available, if you need to insert a barcode for the victorian in the company boundaries; in the first place, it is necessary to read the number "2". However, for the release of products on the market, it is necessary to correct the barcodes from the official administrator.
