GS1 Data Capture Standards
GS1 data capture standards include barcode and radio-frequency identification (RFID) data carriers, which allow GS1 Identification keys and supplementary data to be affixed directly to a physical object. These standards specify consistent interfaces to readers, printers, and other hardware and software components that connect the data carriers to business applications.
Using Application Identifiers, GS1 data carriers are capable of holding varying amounts of data to accommodate different needs for different products and processes. The data encoded in GS1 data carriers not only uniquely identifies products at every level of packaging, it provides access to product information and visibility of product movement through the supply chain.
Barcodes are symbols that can be scanned electronically using laser or camera-based systems. They are used to encode information such as product numbers, serial numbers and batch numbers.
The Electronic Product Code™ (EPC) is syntax for unique identifiers assigned to physical objects, unit loads, locations, or other identifiable entity playing a role in business operations.
When unique EPCs are encoded on to individual RFID tags, radio waves can be used to capture the unique identifiers at extremely high rates and at distances without line-of-sight contact.
