HID Prox & iCLASS vs. ISO/IEC 14443
Comparing 2 standards across 12 specifications. 12 key differences identified.
Comparing:
HID Prox & iCLASS
ISO/IEC 14443
HID Prox and iCLASS are proprietary physical access control credentials developed by HID Global. They encompass legacy 125 kHz unencrypted Prox (such as 26-bit Wiegand H10301), 13.56 MHz read/write iCLASS smart cards, and modern Seos microprocessor cards utilizing AES-128 encryption.
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.
