Abstract:
A method of communication between a terminal and a smart card, said terminal being operatively connected to a smart card reader for communicating with the smart card and a data transmission network (RI), said terminal comprising a first network (RI) access protocol stack, comprising a specified number of communication software layers (C1-C4), and said smart card and smart card reader comprising a second protocol stack and a third protocol stack, each comprising at least lower order software communication layers (CC2-CC1, CCa2-CCa1), to allow data exchange between the smart card and said terminal,said method comprising establishing a first preliminary phase, an interface by a first specific software item in smart card for said lower order communication layers (CCa2-CCa1) of the third protocol stack with at least one application registered in the smart card, establishing a second preliminary phase, which consists of installing, in the terminal, a second specific software item, which functions as an interface with said lower order communication layers (CC2-CC1), of the second protocol stack and with specified layers of said first protocol stack (C2, C3), wherein said first and second specific software items in addition comprise at least one pair of primary coupled software entities, each of said entities cooperating with each other in order, and establishing a session for a bi-directional data exchange between at least one of said terminal and said smart card, and said data transmission network (RI), so that all or part of said data travels through said smart card.
