Abstract: A method for determining a behavior of a smart card, which may be implemented by a server. The method includes operations for obtaining a first reference time data corresponding to a time for setting a smart card clock, and a second reference time data corresponding to a time for reading a first time data from the clock, determining a time drift associated with the smart card based on the first reference time data and on the second reference time data, and determining a behavior of the smart card from the time drift.

Abstract: A card includes a secure element hosting a plurality of applications, at least one external interface and a user interface having user-selectable modes. Each mode is associated with multiple applications. A store at the secure element holds response data for responding to the external card reader and correspondence data. The response data includes data about the applications hosted by the card and the correspondence data indicates, for each mode, a correspondence between the mode and the response data to be sent for that mode. The card allows a user to select one of the plurality of modes for use when the card next communicates with the external reader. The card stores a mode indicator indicative of a mode selected by the user at the user interface and stores a usage indicator indicative of whether the card has communicated with an external reader since the mode indicator was stored.
