TDS 2.x RFID Converter

Convert and analyze RFID EPC codes with support for 8+ GS1 schemes. Based on GS1 EPC Tag Data Standard (TDS) 2.x with automatic scheme detection and IoT-ready Digital Link URIs.

Auto-Detect Decoder

Paste any EPC hex value and we'll automatically detect the scheme and decode all fields

EPC Encoder

Generate EPC hex codes from GTIN, serial numbers, and other identifiers
