GS1 DataMatrix Guideline Overview and technical introduction to the use of GS1 DataMatrix

Aug 30, 2024 · The Function 1 character (FNC1) has a dual purpose in symbols: It is used as a start character or part of a double character start pattern, and to terminate non pre-defined length Application Identifier element strings.

The GS1 General Specifications have always stated that the Function 1 Symbol Character (FNC1) must be used as the data separator in all GS1 barcodes that use the GS1 AI standards. As FNC1 has no ASCII value, when it is used as a separator character it …

Jul 9, 2015 · FNC1 - Structured Data flag character indicating GS1 formatting (in first message character position) or an AIM-standardised industry formatting (in second position) AND as an element separator formatting character (in third and subsequent positions), amongst other uses.

GS1 specifications call for the FNC1 character to be used as a data field separator at the end of a variable-length data field. In IDAutomation GS1 QR-Code symbols the first FNC1 is included with the ~1 character and additional FNC1 characters may be encoded with ~1 in any mode.

The post explains the bullet points in the GS1 Application Identifier Specifications for GS1 barcode users. The Application Identifier (AI) is defined by the digits after the FNC1 character; it must be the first character in a GS1 barcode.

May 11, 2024 · The Function 1 character, or FNC1, is a special character within certain GS1 barcodes. It is primarily used to identify a barcode as a GS1 barcode.

The GS1-128 barcode is a subset of the Code 128 symbology, which contains a flagging character, Function Code 1 (FNC1)).

El carácter de Función 1 o FNC1 es un requerimiento para la correcta estructura de algunas de las simbologías de los Estándares GS1. Se suele utilizar sobre todo en los códigos que concatenan información, como el GS1-128 o el GS1 DataMatrix. El carácter FNC1 tiene dos aplicaciones fundamentales en las simbologías GS1:

GS1 offers a standard to help accomplish this: The GS1 Logistic Label. This guideline provides guidance on how to physically identify logistic units using the GS1 Logistic Label. It is based on the GS1 Standards described in the GS1 General Specifications, and on best practices gathered in various implementation projects around the world.
