Abstract: 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.

Abstract: The disclosure relates to an enrolment method carried out by a smart card using an internal or external electrical power supply, comprising: determining an applied mode among a first and second mode in which the electrical power supply is respectively below and above a predefined threshold; obtaining of N fingerprints in the form of image pixels, N being an integer greater than or equal to 2; extracting digital data representative of characteristic points of the fingerprints by a reading of the pixels at a predetermined resolution level; and generating a fingerprint template by aggregation of the digital data, the enrolment further comprising: determining based on the applied mode of at least one among the number N and the resolution level, so that the fingerprint template has a higher definition in the second mode than in the first mode.

Abstract: A card includes a secure element hosting applications instances. An external interface receive, from an external card reader, an application selection command selecting one application instance from a set of one or more selectable application instances. A biometric interface is configured to acquire biometrics of a user via biometric sensor. A processor compares the acquired biometric data to reference biometric data stored in the card and set the selectable application instance set depending on the outcome of the biometric data comparison. An instance of a non-biometric application is provided in the set only in case of positive comparison. A non-biometric application is thus now biometric-secured. Personalized parameters configuring the instance of a same application may be determined based on the acquired biometrics, allowing configurations of the card to be proposed for several different users.

Abstract: 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.

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.
