What Part of a Barcode Is the Family Code
What is a barcode?
A barcode, consisting of bars and spaces, is a machine-readable representation of numerals and characters. Today, stripes as shown below on packages of products sold at supermarkets, convenience stores and other stores are ubiquitous. These are barcodes. A barcode consists of confined and spaces of varying width that can be read with an optical barcode scanner.
Barcode components
①Tranquility Zone (margin)
Tranquillity Zone is a blank margin located at either end of a barcode. The minimal margin betwixt barcodes (distance from the outermost bar of one barcode to the outermost bar of another barcode) is 2.five mm. If the width of a Placidity Zone is bereft, barcodes are hard for a scanner to read.
②Start Character/Terminate Graphic symbol
The Start Character and the Stop Character are characters representing the showtime and the end of the data, respectively. The characters differ depending on the barcode type.
③Cheque Digit (Symbol cheque graphic symbol)
The Check Digit is a digit for checking whether the encoded barcode data are right.
Barcode types
Common product codes
Mutual product codes are broadly divided into ii groups: UPC and EAN.
- ・ UPC = Universal Product Code
Common product lawmaking standardized in the U.S. - ・ EAN = European Article Number
Mutual product code standardized in Europe based on UPC
In Japan, as a kind of EAN, Jan (Japanese Article Number) is used. EAN (Jan) consists of thirteen digits in the standard version and 8 digits in the shortened version. UPC consists of 12 digits and 7 digits (including the check digit) in the standard and shortened versions, respectively. EAN/UPC has been standardized as an ISO standard (ISO/IEC15420) and a JIS standard (JISX0507). In Nihon, Jan codes are affixed to nutrient, sundry articles, etc. and are mainly used in Point Of Sales (POS) systems.
The composition of a mutual product lawmaking is common in all countries, and a country lawmaking has been assigned to each land.
For example, "49" and "45" are assigned to Japan.
- ・ GS1 Company Prefix
Code obtained past each manufacturer past awarding to the Distribution Systems Research Institute (GS1 Japan) via the Chamber of Commerce and Manufacture of each municipality/prefecture - ・ Production Item Lawmaking
Code determined by each manufacturer, similar to a product lawmaking - ・ Check Digit
Value calculated based on the GS1 Company Prefix and the Product Item Code, which improves the reliability of the data
NW-seven (CODABAR)
NW-7 has a modular composition that can be easily printed with a printer. Information technology is used for shipping labels for door-to-door delivery service, envelopes for photo processing service, etc. Information that tin can be encoded are numerals (0 to nine) and symbols ("-", "$", ":", "/", "+" and ";"). For the Start Character and the Stop Character, A, B, C or D can be selected.
InterLeaved 2 of 5
InterLeaved 2 of 5 enables high-density press, and is used in the logistics field (eastward.g., container boxes) and for small labels affixed to noble metallic and small products. Information technology was standardized as a distribution product barcode symbol (JIS-X-0502) in 1987 and as JIS (JISX0505) in 2004.
CODE39
CODE39 enables the representation of alphabetical characters, and has been adopted as a war machine standard of the U.S Department of Defense (MIL-STD). It is widely used in the factory automation (FA) field and for AIAG, ODETTE and EIAJ tags. Information that tin be encoded are numerals (0 to 9), symbols ("-", " " (space), "$", "/", "+", "%" and ".") and alphabetical messages (A to Z).
CODE128
CODE128 tin encode all 128 characters of ASCII. Information technology is used mainly in the factory automation (FA) and office automation (OA) fields. Information that can be encoded are all 128 characters of ASCII. Information technology comprises three lawmaking sets.
GS1 Databar
GS1 Databar has iii types of seven symbols. GS1 Databar tin can represent data in a smaller expanse than existing barcodes. By using Application Identifiers (AIs), which are standardized by the GS1 Japan, information on product attributes, including expiration dates and lot numbers, can be represented. In 2015, labeling GS1 Databar symbols on all upstanding pharmaceuticals was fabricated obligatory.
