EPC Tag Data Standard TDS

This standard defines the Electronic Product Code (EPC), including its representation at various levels of the GS1 System Architecture and its correspondence to GS1 keys and other existing codes. It also defines the data that is carried on Gen 2 RFID tags, including the EPC, "user memory" data, control information, and tag manufacture information.

This document is for EPC Middleware vendors, RFID tag users and encoders, reader vendors, application developers, and system integrators.
