Interleaved 2 Of 5
Interleaved 2 of 5 (ITF) is a continuous two-width barcode symbology encoding digits. It is used commercially on 135 film, for ITF-14 barcodes, and on cartons of some products, while the products inside are labeled with UPC or EAN. ITF encodes pairs of digits; the first digit is encoded in the five bars (or black lines), while the second digit is encoded in the five spaces (or white lines) interleaved with them. Two out of every five bars or spaces are wide (hence exactly 2 of 5). The digits are encoded to symbols as follows: where "n" is a narrow line (bar or space) and "W" a wide line (2.0 to 3.0 times the width of a narrow line). The wide lines form a two-out-of-five code with consecutive values of 1, 2, 4, 7, and 0, where the code 0 has a value of 11. This is similar to the POSTNET bar code. Before the actual pairs there is a start code consisting of nnnn (narrow bar - narrow space - narrow bar - narrow space), and after all symbols there is the stop code consisting of ...

Barcode25i
A barcode or bar code is a method of representing data in a visual, machine-readable form. Initially, barcodes represented data by varying the widths, spacings and sizes of parallel lines. These barcodes, now commonly referred to as linear or one-dimensional (1D), can be scanned by special optical scanners, called barcode readers, of which there are several types. Later, two-dimensional (2D) variants were developed, using rectangles, dots, hexagons and other patterns, called ''matrix codes'' or ''2D barcodes'', although they do not use bars as such. 2D barcodes can be read using purpose-built 2D optical scanners, which exist in a few different forms. 2D barcodes can also be read by a digital camera connected to a microcomputer running software that takes a photographic image of the barcode and analyzes the image to deconstruct and decode the 2D barcode. A mobile device with an inbuilt camera, such as smartphone, can function as the latter type of 2D barcode reader using specializ ...

POSTNET
POSTNET (Postal Numeric Encoding Technique) is a barcode symbology used by the United States Postal Service to assist in directing mail. The ZIP Code or ZIP+4 code is encoded in half- and full-height bars. Most often, the delivery point is added, usually being the last two digits of the address or PO box number. The barcode starts and ends with a full bar (often called a guard rail or frame bar and represented as the letter "S" in one version of the USPS TrueType Font) and has a check digit after the ZIP, ZIP+4, or delivery point. The encoding table is shown on the right. Each individual digit is represented by a set of five bars, two of which are full bars (i.e. two-out-of-five code). The full bars represent "on" bits in a pseudo-binary code in which the places represent, from left to right: 7, 4, 2, 1, and 0. (Though in this scheme, zero is encoded as 11 in decimal, or in POSTNET "binary" as 11000.) Encoding The following table shows the encoding for decimal digits: ...

Two-out-of-five Code
A two-out-of-five code is a constant-weight code that provides exactly ten possible combinations of two bits, and is thus used for representing the decimal digits using five bits. Each bit is assigned a weight, such that the set bits sum to the desired value, with an exception for zero. According to Federal Standard 1037C: * each decimal digit is represented by a binary numeral consisting of five bits of which two are of one kind, called ''ones'', and three are of the other kind, called ''zeros'', and * the usual weights assigned to the bit positions are 0-1-2-3-6. However, in this scheme, zero is encoded as binary ''01100''; strictly speaking the 0-1-2-3-6 previously claimed is just a mnemonic device. The weights give a unique encoding for most digits, but allow two encodings for 3: 0+3 or 10010 and 1+2 or 01100. The former is used to encode the digit 3, and the latter is used to represent the otherwise unrepresentable zero. The IBM 7070, IBM 7072, and IBM 7074 computers ...

Deutsche Post
The Deutsche Post AG, operating under the trade name Deutsche Post DHL Group, is a German multinational package delivery and supply chain management company headquartered in Bonn, Germany. It is one of the world's largest courier companies. The postal division delivers 61 million letters each day in Germany, making it Europe's largest such company. The Parcel division DHL is a wholly owned subsidiary claimed to be present in over 220 countries and territories. The Deutsche Post is the successor to the German mail authority Deutsche Bundespost, which was privatized in 1995 and became a fully independent company in 2000. Since its privatization, Deutsche Post has significantly expanded its business area through acquisitions. In late 2014, the group acquired StreetScooter GmbH, a small manufacturer of electric vehicles. Two years later, the group acquired UK Mail, a business-focused postal service in the UK for US$315.5 million (£243 million). The former company became a divi ...

DX Camera Auto-Sensing Code
DX (Digital indeX) encoding is an ANSI and I3A standard, originally introduced by Kodak in March 1983, for marking 135 and APS photographic film and film cartridges. It consists of several parts, a latent image DX film edge barcode on the film below the sprocket holes, a code on the cartridge used by automatic cameras, and a barcode on the cartridge read by photo-finishing machines. History In order to simplify the handling of 35 mm film in 135 format Kodak introduced the DX encoding method on 3 January 1983. In contrast to former solutions like Fuji's film speed encoding method in 1977, which was already using electrical contacts for film speed detection on 135 format cartridges, Kodak's later DX code system immediately met success in the marketplace. The first DX encoded film was the color negative film Kodacolor VR-1000 in March 1983. The first cameras to use the technology was the Konica TC-X SLR (1985), [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Global Trade Item Number
The Global Trade Item Number (GTIN) is an identifier for trade items, developed by the international organization GS1. Such identifiers are used to look up product information in a database (often by entering the number through a barcode scanner pointed at an actual product) which may belong to a retailer, manufacturer, collector, researcher, or other entity. The uniqueness and universality of the identifier is useful in establishing which product in one database corresponds to which product in another database, especially across organizational boundaries. Format and incorporated standards The GTIN standard has incorporated the International Standard Book Number (ISBN), International Standard Serial Number (ISSN), International Standard Music Number (ISMN), International Article Number (which includes the European Article Number and Japanese Article Number) and some Universal Product Codes (UPCs), into a universal number space. GTINs may be eight, 12, 13, or 14 digits long, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Universal Product Code
The Universal Product Code (UPC or UPC code) is a barcode symbology that is widely used worldwide for tracking trade items in stores. UPC (technically refers to UPC-A) consists of 12 digits that are uniquely assigned to each trade item. Along with the related International Article Number (EAN) barcode, the UPC is the barcode mainly used for scanning of trade items at the point of sale, per the specifications of the international GS1 organisation. UPC data structures are a component of Global Trade Item Numbers (GTINs) and follow the global GS1 specification, which is based on international standards. But some retailers (clothing, furniture) do not use the GS1 system (rather other barcode symbologies or article number systems). On the other hand, some retailers use the EAN/UPC barcode symbology, but without using a GTIN (for products sold in their own stores only). Research indicates that the adoption and diffusion of the UPC stimulated innovation and contributed to the growth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

European Article Number
The International Article Number (also known as European Article Number or EAN) is a standard describing a barcode symbology and numbering system used in global trade to identify a specific retail product type, in a specific packaging configuration, from a specific manufacturer. The standard has been subsumed in the Global Trade Item Number standard from the GS1 organization; the same numbers can be referred to as GTINs and can be encoded in other barcode symbologies defined by GS1. EAN barcodes are used worldwide for lookup at retail point of sale, but can also be used as numbers for other purposes such as wholesale ordering or accounting. These barcodes only represent the digits 0–9, unlike some other barcode symbologies which can represent additional characters. The most commonly used EAN standard is the thirteen-digit EAN-13, a superset of the original 12-digit Universal Product Code (UPC-A) standard developed in 1970 by George J. Laurer. An EAN-13 number includes a 3-di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
