GS1 also acts as the secretariat for ISO's Automatic identification and data capture techniques technical committee (ISO/IEC JTC 1/SC 31). [12] GS1 standards are developed and maintained through the GS1 Global Standards Management Process (GSMP), a community-based forum that brings together representatives from different industries and businesses.
The Global Trade Item Number (GTIN) is an identifier for trade items, developed by the international organization GS1. [1] 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.
An example of a generic RFID chip. Some produce traceability makers use matrix barcodes to record data on specific produce. The international standards organization EPCglobal under GS1 has ratified the EPC network standards (esp. the EPC information services EPCIS standard) which codify the syntax and semantics for supply chain events and the secure method for selectively sharing supply chain ...
The check digit is an additional digit, used to verify that a barcode has been scanned correctly. It is computed modulo 10, where the weights in the checksum calculation alternate 3 and 1. In particular, since the weights are relatively prime to 10, the EAN-13 system will detect all single digit errors.
In order to automate the reading process, the SSCC is often encoded in a barcode, generally GS1-128, and can also be encoded in an RFID tag. It is used in electronic commerce transactions. The SSCC comprises an extension digit, a GS1 company prefix, a serial reference, and a check digit. It is all numeric.
GS1 identification keys [4] includes detailed information about 12 GS1 ID keys, their purpose, use, allocation and maintenance rules, etc. GS1 Application Identifiers [5] defines the prefixes (AIs) used in barcodes and EPC/RFID-tags to define the meaning and format of identifiers, and currently lists 516 kinds of identifiers.
Within a product's supply chain, traceability may be both a regulatory and an ethical or environmental issue. [3] Traceability is increasingly becoming a core criterion for sustainability efforts related to supply chains wherein knowing the producer, workers and other links stands as a necessary factor that underlies credible claims of social, economic, or environmental impacts.

GEPIR is a lookup service coordinated by the GS1 GO that provides all end users with the ability to look up information about GS1 Identification Keys. [ 6 ] Depending on the service, systems are provided by GS1 Member Organisations (MOs) or 3rd party service providers, or both.
