Calypso: a full set of providers in a truly competitive environment

In the page Providers, the openness of Calypso is demonstrated in each category of manufacturers providing a part of a ticketing system: IC manufacturers, card embedders, fare collection providers, etc.

And from2011, for terminal manufacturers, there is no more Calypso license, because only the SAM (Secure Application Module) is subject to license: all terminal manufacturers are able to provide Calypso terminals.
