A card comprising: a first external interface configured to receive, from an external card reader , an application selection command selecting an application instance from a set of one or more selectable application instances ; a second external interface or an internal biometric interface , either interface being configured to acquire biometric data; and a processor configured to compare the acquired biometric data to reference biometric data stored in the card; and to set the set of one or more selectable application instances depending on an outcome of the comparison of the acquired biometric data to the reference biometric data, wherein the set of one or more selectable application instances comprises the application instance configured with personalized parameters, wherein the personalized parameters depend on the outcome of the comparison of the acquired biometric data to the reference biometric data, wherein the personalized parameters are selected from one of the following sets: - in case the outcome of the comparison of the acquired biometric data to the reference biometric data is negative, requesting a personal code to a user to perform a function of the application instance, or not requesting the personal code in case the outcome of the comparison of the acquired biometric data to the reference biometric data is positive; - in case the outcome of the comparison of the acquired biometric data to the reference biometric data is negative, restricting a function of the application instance, or not restricting the function in case the outcome of the comparison of the acquired biometric data to the reference biometric data is positive. a first external interface configured to receive, from an external card reader , an application selection command selecting an application instance from a set of one or more selectable application instances ; a second external interface or an internal biometric interface , either interface being configured to acquire biometric data; and a processor configured to compare the acquired biometric data to reference biometric data stored in the card; and to set the set of one or more selectable application instances depending on an outcome of the comparison of the acquired biometric data to the reference biometric data, wherein the set of one or more selectable application instances comprises the application instance configured with personalized parameters, wherein the personalized parameters depend on the outcome of the comparison of the acquired biometric data to the reference biometric data, wherein the personalized parameters are selected from one of the following sets: - in case the outcome of the comparison of the acquired biometric data to the reference biometric data is negative, requesting a personal code to a user to perform a function of the application instance, or not requesting the personal code in case the outcome of the comparison of the acquired biometric data to the reference biometric data is positive; - in case the outcome of the comparison of the acquired biometric data to the reference biometric data is negative, restricting a function of the application instance, or not restricting the function in case the outcome of the comparison of the acquired biometric data to the reference biometric data is positive. - in case the outcome of the comparison of the acquired biometric data to the reference biometric data is negative, requesting a personal code to a user to perform a function of the application instance, or not requesting the personal code in case the outcome of the comparison of the acquired biometric data to the reference biometric data is positive; - in case the outcome of the comparison of the acquired biometric data to the reference biometric data is negative, restricting a function of the application instance, or not restricting the function in case the outcome of the comparison of the acquired biometric data to the reference biometric data is positive. <EOS>
