Abstract: This invention concerns a computer communication method using asynchronous messages in a distributed software architecture, for example of type AAA-MOM (Agent Anytime Anywhere—Message Oriented Middleware), including a disconnectable platform such as a smartcard. This communication is carried out between firstly a card agent (CA), stored in a removable platform (31, 32), connectable to a terminal (21, 22), and secondly at least one standard software agent (AS). This standard agent can be stored in this computer network (1), in another removable platform. A message sent by the card agent (CA) to a standard agent (AS) or sent by a standard agent (AS) to the card agent (CA), is stored in the network by at least one intermediate agent (CEPA, CAPA) managing the communications of this card agent (CA) with the network (1).
