This document contains a functional description of the Calypso ticketing card application.
Calypso contactless cards are contactless smartcards for payment of public transport compatible with the Calypso specification. They are used as part of a secure contactless system including a central system, reloading equipment, validators, and possible other equipments.
All parts of the system must be designed with some of the major goals of a secure contactless system in mind, particularly the speed and security of transactions. The present manual therefore contains some guidelines on the card uses, some typical transactions descriptions and guidelines on the overall system design.
