HID Prox & iCLASS vs. ISO/IEC 15693
Comparing 2 standards across 12 specifications. 12 key differences identified.
Comparing:
HID Prox & iCLASS
ISO/IEC 15693
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 15693 (NFC Forum Type 5) is an international standard for High-Frequency (13.56 MHz) Vicinity Integrated Circuit Cards (VICC). Engineered with relaxed power requirements and highly sensitive subcarrier modulation, it achieves read ranges up to 1 to 1.5 meters, making it the standard for library item tracking, ski resort passes, and pharmaceutical logistics.
