CA 2554391

A portable data carrier (10) and a method (B1-B10), as well as a storage medium with instructions, for transferring data by means of a portable data carrier are provided. The portable data carrier comprises a carrier storage (12) for storing data containing a biometric template (13) and an application- specific function (15) as well as carrier communication means (11) for contactless receipt and transmission of data. The portable data carrier is characterised in that it further comprises carrier processing means (16) for comparing the biometric template with a biometric sample (23) received from an external arrangement (20), and that it is arranged to complete a handshake process with the external arrangement as well as perform the application- specific function and transmit a result of the same to the external arrangement, only if the biometric sample matches the biometric template.

L'invention concerne un support (10) de données portable, et un procédé associé (B1-B10), ainsi qu'un support de stockage comprenant des instructions de transfert de données au moyen d'un support de données portable. Le support de données portable comprend un dispositif (12) de stockage de données contenant un modèle biométrique (13) et une fonction (15) spécifique à l'application, ainsi qu'un moyen (11) de communication de réception et de transmission sans contact des données. Le support de données portable se caractérise en ce qu'il comprend également un moyen (16) de traitement permettant de comparer le modèle biométrique avec un échantillon biométrique (23) reçu d'un dispositif externe (20), et en ce qu'il permet de compléter un processus d'établissement de liaison avec le dispositif externe, d'exécuter la fonction spécifique à l'application et de transmettre un résultat de celle-ci au dispositif externe, seulement si l'échantillon biométrique correspond au modèle biométrique.
