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 .
The GS1-128 symbology is a subset of the more general Code 128 symbology. By agreement between AIM and GS1, use of the Function 1 Symbol Character (FNC1) in Code 128 symbols in the first symbol character position following the start character has been reserved exclusively for the GS1 system. Code 128 is fully described in ISO/IEC 15417
[9] [10] Codablock A was based on stacked Code 39 barcodes and wasn’t widely used because of Code 39 restrictions. The next Codablock F [11] [12] was based on stacked Code 128 symbology and was standardized as AIM standard in 1995. [13] As this time Codablock F is officially accessed as historical standard and isn’t recommended to use in ...
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 ...
Rectangular Micro QR Code can encode GS1 Data with FNC1 in first position. [2]: 7.4.8.2 Encoding mode indicator 101 switch the barcode symbol in GS1 Application Identifiers [9] mode. FNC1 cannot be used as split FNC1 character like in Code 128 symbol. Instead of this, % character should be used in alphanumeric mode or GS (0x1D) in byte mode.
DotCode barcode was invented in 2008 [1] by Dr. Andrew Longacre from Hand Held Products company and standardized in 2009 [6] by AIM as “Bar code symbology specification - DotCode”. [7] In 2019 DotCode was reviewed as “ISS DotCode Symbology Specification 4.0”. [2] Set of patents is registered, which are related with DotCode encoding and ...
However there are even more symbols and codes care takers should be aware of in order to protect children from predators. SEE ALSO: Mother horrified after learning what heart symbol on daughter's ...
There are in fact several types of linear bar codes, including Code 128, a bar code standard widely used in coding standards such as GS1 and ISBT 128. Higher capacity delivery systems are available using 2-dimensional or reduced space symbology bar codes. These codes can carry much more information in each symbol.
