Document Summary
The Calypso Card API is a high-level API used by the Ticketing Layer standardizing the way to interact with a Calypso product (card, SAM, etc.). It defines the interfaces and classes needed to operate a Calypso card transaction and recover a Calypso card image.
The Calypso Card API is proposed in 2 programming languages Java & C++, but these versions are based on the same object-oriented model.
