ISO/IEC 15693 vs. NFC Forum Tag Types

Comparing 2 standards across 13 specifications. 12 key differences identified.

Comparing:
ISO/IEC 15693
NFC Forum Tag Types

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.

NFC Forum Tag Types (Types 1 through 5) are standardized memory and communication specifications established by the NFC Forum, operating at 13.56 MHz. They define how data is formatted in NFC Data Exchange Format (NDEF) across underlying ISO/IEC 14443 Type A/B, FeliCa, and ISO/IEC 15693 radio architectures.
