Abstract: A mobile terminal is provided by an issuing authority for capturing biometric data of a user for transmission to a security document. The mobile terminal includes a data storage unit containing a credential, an authentication module, a sensor for capturing the biometric data of the user and a control unit that is configured to capture the biometric data of the user only upon successful reciprocal authentication of the user and the mobile terminal. An authenticity test module tests the authenticity of the captured biometric data captured. If authentic, the captured biometric data is stored in the data storage unit in protected form. Readout of the biometric data from the mobile terminal, by an operator of the issuing authority, is permitted only if the operator has been authenticated to the mobile terminal using additional authentication data.

Abstract: The invention relates to a security or valuable document having at least first and second display devices (118; 128), a processor (102, 108) for driving the at least first and second display devices, an interface (112) for supplying power to the processor from an external power source (114, 136).
