Abstract
The invention relates to a method for activating one (A.sub.i) of the applications (A.sub.i -A.sub.n) of an on-board or embedded system, particularly of a chip card (2a) connected to a terminal (1) equipped with a reader, by means of a 'web' browser. The terminal (1) and the chip card (2a) each comprise, in addition to the conventional protocol layers (101-102) corresponding to the ISO 7816 standards, a specific layer (13, 23a). The latter comprises intelligent agents (132, 231a.sub.1) for establishing two-way data exchange sessions, enabling the chip card (2a) to offer a 'web' server functionality. In addition, the chip card (2a) comprises intelligent agents (ATS.sub.1 -ATS.sub.n) called script translators that interact with the applications (A.sub.i -A.sub.n), making it possible to activate a selected application (A.sub.i) using conventional commands corresponding to the ISO 7816 standards. In a variant of embodiment, provisions are made for a dynamic updating of the chip card (2a), particularly from the browser. The invention also relates to the corresponding on-board system.
