Semacode
Semacode is a software company based in Waterloo, Ontario, Canada. It is also this company's trade name for their machine-readable International Organization for Standardization, ISO/IEC 16022 Data Matrix 2D barcode, barcodes, which are used to encode Internet Uniform Resource Locator, URLs. Semacodes are primarily aimed at being used with cellular phones which have built-in cameras, to quickly capture a Web site address for use in the phone's web browser. Semacodes are in fact DataMatrix encoded URLs. The Semacode website states that Semacode tags are an "open system" and that tag creation is "completely unrestricted," with the SDK software tools being free of charge for non-commercial use. Potential uses for Semacode tags are still being explored, and will complement development of the concept of using mobile phones as devices for information gathering and exchange.

Object Hyperlinking
Object hyperlinking is extending the Internet to objects and locations in the real world. Object hyperlinking aims to extend the Internet to the physical world by attaching tags with URLs to tangible objects or locations. These object tags can then be read by a wireless mobile device and information about objects and locations retrieved and displayed. However, object hyperlinking may also be sensible for contexts other than the Internet (e.g. with data objects in data base administering or with text content management). System components Linking an object or a location to the Internet is a more involved process than linking two web pages. An object hyperlinking system requires seven components: #A virtual or physical object tag to identify objects and locations. Some tagging systems are described below. To allow the object tags to be located they must be physically embedded in visual markers. For example, the Yellow arrow scheme ee belowprints SMS tags on large adhesive ye ...

DataMatrix
A Data Matrix is a two-dimensional code consisting of black and white "cells" or dots arranged in either a square (geometry), square or rectangle, rectangular pattern, also known as a matrix (mathematics), matrix. The information to be encoded can be text or numeric data. Usual data size is from a few bytes up to 1556 bytes. The length of the encoded data depends on the number of cells in the matrix. Error correction codes are often used to increase reliability: even if one or more cells are damaged so it is unreadable, the message can still be read. A Data Matrix symbol can store up to 2,335 alphanumeric characters. Data Matrix symbols are rectangular, usually square in shape and composed of square "cells" which represent bits. Depending on the coding used, a "light" cell represents a 0 and a "dark" cell is a 1, or vice versa. Every Data Matrix is composed of two solid adjacent borders in an "L" shape (called the "finder pattern") and two other borders consisting of alternating ...

Barcodes
A barcode or bar code is a method of representing data in a visual, Machine-readable data, 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 ''2D barcodes'' or ''matrix codes'', although they do not use bars as such. Both can be read using purpose-built 2D optical scanners, which exist in a few different forms. Matrix codes 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 code. A mobile device with a built-in camera, such as a smartphone, can function as the latter type of barcode reader usin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cauzin Softstrip
Cauzin Softstrip was the first commercial 2D barcode format. Introduced in 1985, it could store up to 1000 bytes per square inch, which was 20 to 100 times more than the bar codes of the day. It was designed for paper data storage, to allow magazines to distribute computer programs by simply printing a pattern on a page. Several computer magazines printed Softstrip data that encoded program source listings, or even executable programs. It is now known as Datastrip code. Softstrip format never became very popular for program distribution. It was intended to replace the tedium of entering type-in programs from magazines, but the format encoded less than a thousand bytes per square inch, on the format which meant that large files took up a lot of space in a magazine. The bar codes didn't work well if the magazine ink was smeared; and the reader hardware was relatively expensive at around US$200. The high cost of the unit and the added demands placed on publishers led to a chicken ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

SPARQCode
A SPARQCode is a matrix code (or two-dimensional bar code) encoding standard that is based on the physical QR Code definition created by Japanese corporation Denso-Wave. Overview The QR Code standard as defined by Denso-Wave in ISO/IEC 18004 covers the physical encoding method of a binary data stream. However, the Denso-Wave standard lacks an encoding standard for interpreting the data stream on the application layer for decoding URLs, phone numbers, and all other data types. NTT Docomo has established de facto standards for encoding some data types such as URLs, and contact information in Japan, but not all applications in other countries adhere to this convention as listed by the open-source project " zxing" for QR Code data types. Encoding standards The SPARQCode encoding standard specifies a convention for the following encoding data types. * E-mail address * Phone Number * SMS TEXT * MAP * URL * BIZCARD * MeCard * vCard * BlackBerry PIN * Geographic informatio ...

High Capacity Color Barcode
High Capacity Color Barcode (HCCB) is a technology developed by Microsoft for encoding data in a 2D "barcode" using clusters of colored triangles instead of the square pixels conventionally associated with 2D barcodes or QR codes. Data density is increased by using a palette of 4 or 8 colors for the triangles, although HCCB also permits the use of black and white when necessary. It has been licensed by the ISAN International Agency for use in its International Standard Audiovisual Number standard, and serves as the basis for the Microsoft Tag mobile tagging application. The technology was created by Gavin Jancke, an engineering director at Microsoft Research. Quoted by BBC News in 2007, he said that HCCB was not intended to replace conventional barcodes. "'It's more of a 'partner' barcode", he said. "The UPC barcodes will always be there. Ours is more of a niche barcode where you want to put a lot of information in a small space." Technology HCCB uses a grid of colored tria ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

PDF417
PDF417 is a stacked linear barcode format used in a variety of applications such as transport, identification cards, and inventory management. "PDF" stands for ''Portable Data File'', while "417" signifies that each pattern in the code consists of 4 bars and spaces in a pattern that is 17 units (modules) long. The PDF417 symbology was invented by Dr. Ynjiun P. Wang at Symbol Technologies in 1991. It is defined in ISO 15438. Design components of a PDF417 barcode The PDF417 bar code (also called a ''symbol'') consists of 3 to 90 rows, each of which is like a small linear bar code. Each row has: * A ''quiet zone''. This is a mandated minimum amount of white space before the bar code begins. * A start pattern which identifies the format as PDF417. * A "row left" codeword containing information about the row (such as the row number and error correction level) * 1–30 data ''codewords'': Codewords are a group of bars and spaces representing one or more numbers, letters, or ...
