Calypso vs. ISO/IEC 15693

Comparing 2 standards across 12 specifications. 11 key differences identified.

Comparing:
Calypso
ISO/IEC 15693

Calypso is an open international contactless electronic ticketing standard managed by the Calypso Networks Association, operating under ISO/IEC 14443 Type B (and Type A). Developed by European transit operators to prevent proprietary lock-in with NXP MIFARE, it powers major transit networks including the Paris Navigo, Lisbon Viva, and Belgium MoBIB.

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.
