A method carried out by a smart card including a fingerprint sensor, the method including an authentication phase including: acquiring a sequence of object prints from objects detected over time by the fingerprint sensor; comparing the sequence of object prints with reference data defining a reference sequence of object prints according to at least two different print types; and determining that the authentication phase is successful if the sequence of object prints coincides with the reference data. During a digital enrollment phase, the smart card generates, from at least one fingerprint, called enrollment fingerprint, digital enrollment data; and records these digital enrollment data so as to allow subsequent digital authentication from said digital enrollment data.

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.

To ensure the quality of NFC communication between a contactless card and a smartphone, a positioning pattern, for example a portion of the card visual, is displayed on the screen of the smartphone. This is a visual aid to help the user to position the contactless card, in proximity to the smartphone, toward a position where a card indicator for which provision is made on the card, typically the portion complementary to the card visual, is aligned with the displayed pattern. The positioning is made easy as the positioning pattern and the card indicator are preferably chosen to be visually complementary. Also, the contactless card is in the appropriate position when the card indicator visually complements the positioning pattern. The positioning pattern is thus displayed at a location of the screen allowing the best NFC coupling between the card and the smartphone.

Disclosed is a method for managing the connections between a secure element and a server of a communication network, the secure element being incorporated in a host device. The method includes the following steps: &#x2014;determination of a theoretical time period between two consecutive instants of connection, &#x2014;determination of a real time period between two consecutive instants of connection between the secure element and the server, &#x2014;comparison of the determined theoretical time period with the determined real time period, and if the determined theoretical time period is different from the determined real time period: &#x2014;determination of a new theoretical time period.
