Abstract

An entity of the smart card type has an application layer linked to a communication protocol layer. A time manager containing a timer interfaces with the protocol layer. The time manager substantially periodically constructs waiting time extension requests transmitted to a terminal through the protocol layer as long as data are being processed in the application layer. The application layer is thus freed from any time constraint.
