A Swiss postal barcode encoding "RI 476 394 652 CH" in Code 128 (B & C) Code 128 is a high-density linear barcode symbology defined in ISO/IEC 15417:2007. [1] It is used for alphanumeric or numeric-only barcodes. It can encode all 128 characters of ASCII and, by use of an extension symbol (FNC4), the Latin-1 characters defined in ISO/IEC 8859-1.
Barcode library or Barcode SDK is a software library that can be used to add barcode features to desktop, web, mobile or embedded applications. Barcode library presents sets of subroutines or objects which allow to create barcode images and put them on surfaces or recognize machine-encoded text / data from scanned or captured by camera images with embedded barcodes.
The Code 16K (1988) is a multi-row bar code developed by Ted Williams at Laserlight Systems (USA) in 1992. In the US and France, the code is used in the electronics industry to identify chips and printed circuit boards. Medical applications in the USA are well known. Williams also developed Code 128, and the structure of 16K is based on Code 128.
DotCode can encode full 8-bit charset in two ways: [2]: 5.2.1.1 With Upper Shift, which requires 2 codewords on one (128 to 255) symbol; With Binary Latch, which requires 1 Binary Latch symbol and 6 codewords on every 5 bytes. Upper Shift modes can encode (128 to 255) extended ASCII characters in two codewords with returning to previous mode:
Code 39 (also known as Alpha39, Code 3 of 9, Code 3/9, Type 39, USS Code 39, or USD-3) is a variable length, discrete barcode symbology defined in ISO/IEC 16388:2007. The Code 39 specification defines 43 characters, consisting of uppercase letters (A through Z), numeric digits (0 through 9) and a number of special characters ...
Codablock symbologies [16] [17] has been developed as a stacked version of Code 39 and Code 128 barcodes and has some advantages of 2D barcodes. They allow to utilize rectangular space more effectively then 1D barcode and have additional checking characters to ensure the content of the overall message.
Plessey Code is a 1D linear barcode symbology based on pulse-width modulation, developed in 1971 by The Plessey Company plc, a British-based company. [1] It is one of the first barcode symbology , and is still used rarely in some libraries and for shelf tags in retail stores, in part as a solution to their internal requirement for stock control.
Although Codabar has not been registered for United States federal trademark status, its hyphenated variant, Code-a-bar, is a registered trademark. [ 2 ] Codabar was designed to be accurately read even when printed on dot matrix printers for multi-part forms such as FedEx airbills and blood bank forms, where variants are still in use as of 2007 ...
