摘要： A data carrier (1) comprises at least one optically variable element (2), at least one surface element (3a), and at least one security element (4) comprising at least part of the at least one optically variable element (2) and at least part of the at least one surface element (3a). The at least one surface element (3a) is configured to guide impinging electromagnetic radiation (EM) towards the at least one optically variable element (2). The data carrier (1) is configured such, that electromagnetic radiation (EM) is impinging on the at least one surface element (3a) under at least a first arrival angle (α1) when the data carrier (1) is seen under a first observation angle (γ1), and such, that electromagnetic radiation (EM) is impinging on the at least one surface element (3a) under at least a second arrival angle (β1) being different from the first arrival angle (α1) when the data carrier (1) is seen under a second observation angle (γ2) being different from the first observation angle (γ1). The at least one optically variable element (2) is configured to reflect at least a first reflection spectrum (R1a) upon impingement of the electromagnetic radiation (EM) being impinging on the at least one surface element (3a) under the first arrival angle (α1), whereby the at least one security element (4) appears according to at least a first appearance (A1a), and is further configured to reflect at least a second reflection spectrum (R2a) upon impingement of the electromagnetic radiation (EM) being impinging on the at least one surface element (3a) under the second arrival angle (β1), whereby the at least one security element (4) appears according to at least a second appearance (A2a) being different from the first appearance (A1a).

摘要： The invention is a method for managing, in a card, a PIN code having a value and a state which can be set either to locked or to unlocked. The card triggers the generation of a cryptogram only if the user has been successfully authenticated using its biometric sensor. The card sends the cryptogram to a remote server (40) via a communicating device (30). Only if the cryptogram is found to be valid, the remote server identifies an admin code and a user code value both associated to the card and sends the admin code and the user code value to the communicating device. The communicating device provides the user with the user code value through its user interface, identifies a data comprising the admin code then sends said data to the card which sets the state of the PIN code to unlocked by using said data.

摘要： The invention is a method for managing a biometric smart card (10) associated to a user (50). The biometric smart card comprises a reference biometric data (21) previously enrolled by the user, a secure element (20), a biometric sensor (40) and a controller (30) coupled to the biometric sensor (40). The controller comprises a first firmware (31). The method comprises the following steps: - the secure element receives a second firmware (32) originated from a remote server (90), - establishing a secure channel between the secure element and the controller by using keys pre-stored in said secure element and controller, - the secure element sends the second firmware to the controller through the secure channel, and - the secure element applies a policy to deactivate the first firmware and activate the second firmware.
