Comparing:
Calypso
RAIN RFID / EPC Gen2

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.
