Abstract: A method implemented in an electronic entity capable of implementing a plurality of applications includes the following steps: detecting an electrical signal (D; D?); reading, in a memory of the electronic entity, information relating, among the plurality of applications, to a previously selected application; and transmitting a command (CMD) to deliver an indication associated with the application to which the read information relates. An associated electronic entity is also described.

Abstract: A calibration method for calibrating a clock of a circuit for a smart card, which includes operations for: at a first instant, storing (S310) first time data from a terminal in the clock; at a second instant, reading (S320) second time data from the clock and corresponding to the first time data incremented by the clock as a function of a first duration between the first instant and the second instant; comparing (S330) the second time data with third time data corresponding to the first time data incremented, by the terminal or by a remote server, as a function of the first duration between the first instant and the second instant; as a function of the result of the comparison, calculating (S340) first calibration data; and storing (S350) the first calibration data in the clock. The reading of the second time data may be in a contactless manner.
