EPCglobal US helps subscribers deploy standards-compliant solutions.
The organization leverages the EPCglobal system of standards, which provides a cohesive global framework for the identification, capture and exchange of RFID data. EPCglobal US has built a community of members, including suppliers, retailers, associations and solution providers, within and across industries, to help drive best practices, solve business issues and provide ongoing guidance during deployment. As a not-for-profit subsidiary of GS1 US, EPCglobal US can help subscribers extend and enhance existing investments in the GS1 system of identification (GTIN, GLN, SSCC), as well as data synchronization (the 1SYNC data pool) and Electronic Data Interchange (EDI).
