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.

Abstract: A security device includes a body and a contact interface including an external connection for external communication and an internal connection for internal communication. The body includes at least a first substrate and a second substrate lying in respective parallel planes. The contact interface is electrically connected to the first substrate and to the second substrate by the internal connection. The security device is a chip card, for example a bank card, or an identity document.

Abstract: A microcircuit card (31) comprising a microcircuit and a card body, characterized in that this card body is formed of a base (10) in which is formed a cavity provided with a bottom and an internal part fixed in the cavity and to which the microcircuit is joined, the internal part and the microcircuit (12) together constituting at least a part of a second microcircuit card (11) including at least a part of the body of said second card.
