RAIN RFID / EPC Gen2 vs. ISO/IEC 14443
Comparing 2 standards across 15 specifications. 15 key differences identified.
RAIN RFID (ISO/IEC 18000-63 / GS1 EPC Gen2) is an Ultra-High Frequency (UHF, 860–960 MHz) wireless standard utilizing electromagnetic backscatter coupling. Enabling simultaneous inventory reading of hundreds of passive tags per second over distances up to 12 meters, it is the global standard for retail apparel, aviation baggage, and logistics supply chains.
ISO/IEC 14443 is the international standard governing contactless Proximity Integrated Circuit Cards (PICC) and Proximity Coupling Devices (PCD) operating at 13.56 MHz over distances up to 10 cm. It defines two distinct physical and framing architectures—Type A and Type B—and forms the foundation of EMV contactless payment cards and ICAO biometric ePassports.
