Method of setting up a communication session via an SWP interface

Abstract

Disclosed are methods performed by, and devices including, a microcircuit card that makes it possible to set up a communication session between the microcircuit card and a contactless communication module via an SWP interface. An implementation of the method comprises: an initialization phase for the SWP interface; and a negotiation phase between the microcircuit card and the contactless communication module, the contactless communication module being suitable for maintaining the power supply of said microcircuit card during these phases. Among other reasons, the method is remarkable in that the microcircuit card prolongs said negotiation phase until the end of a procedure internal to the microcircuit card.
