Identification
EPC
Electronic Product Code
The GS1 identifier scheme used inside UHF RFID tags — a serialised, machine-readable extension of GTIN for the supply chain.
EPC is the binary identifier carried on a UHF RFID Gen2 tag. The most common form is SGTIN-96, which packs a GTIN plus a serial number into 96 bits.
EPC events flowing through EPCIS are how brands and retailers know which serial moved through which facility — feeding inventory accuracy, recall execution and DPP lifecycle data.
