Abstract
The method comprises the steps of: coupling the card (24) as initially configured for the default application, with a terminal (14) of the default application, executing a special transaction for reconfiguring the software of the card for the target application so that the card as reconfigured in this way emulates a card specific to the target application; coupling the card as reconfigured in this way with a terminal (18) of the target application; and executing a transaction of the target application. Subsequently, the card as reconfigured for the target application can be coupled with a terminal of the default application, and another special transaction can be executed to return the card to its software configuration for the default application. In particular, the default application can be a SIM card application for GSM radiotelephony, and the target application can be a token-carrier type application.
