Abstract

A smart card includes a plurality of application circuits that are each related to at least one application service securely contained within the card, each application circuit is energizable by an outside signal; a control unit making it possible to identify the energized application circuit and the related service and moreover to activate the service in response to activation authorization; and a biometric circuit for authenticating the user so as to generate the activation authorization.

Claims

1. A secured communication device, comprising:

a plurality of application circuits disposed in the device, which are each related to at least one application service securely contained within the device, each application circuit being excitable by an external signal received from a surrounding environment of the device, and selectively responsive to a given physical phenomenon of the surrounding environment of the device;

a control unit disposed in the device making it possible to identify the excited application service, the related application service and to activate said application service in response to an activation authorization; and

a biometric circuit disposed in the device for authenticating a user so as to generate said activation authorization,

wherein at least one of said plurality of application circuits, being coupled to said control unit and said biometric circuit within the device, detects said external signal based on the given physical phenomenon caused by said external signal,

wherein an authorization request is transmitted from said corresponding application circuit to said biometric circuit, and upon receiving the authorization request, said biometric circuit starts an authentication process for identifying the user,

wherein said biometric circuit performs biometric comparison with data contained in the device, and upon satisfactory comparison, an agreement signal is sent from said biometric circuit to said corresponding application circuit for granting said activation authorization, and

wherein said application service is activated based on said activation authorization such that said corresponding application circuit interacts with the surrounding environment.

2. The device according to claim 1, wherein the application circuits include a radiofrequency signal transceiver.

3. The device according to claim 1, wherein the application circuits include at least one metal connector.
