Abstract: A method for reading an identity document, a readout terminal and a readout system, which simplifies the multiple reading of identity documents. According to the method, an authentication key and an information item are stored in hidden fashion in the chip of the identity document.

Abstract: The present invention relates to a method for carrying out an identity check in a screening corridor (10), in which the individuals (20) to be screened carry, when passing through the screening corridor (10), a mobile apparatus (22) that permits a determination of the position of the individual (20) within the screening corridor (10), the mobile apparatuses (22) of the individuals (20) to be screened transmit to a screening entity (100) in each case via a communication link, as identification data of the individual, the individual's (20) biometric reference values to be checked in each case, the screening entity (100) position-dependently detects, by means of at least one detection device (40), biometric actual values of the individuals (20) to be screened, the positions of the individuals (20) to be screened within the screening corridor (10) are determined with the aid of the mobile apparatuses (22) carried by said individuals, and the screening entity (100) checks for agreement the position-dependently det

Abstract: A method for replacing the operating software of a limited-resource portable data carrier at a terminal includes controlling the operation of the data carrier and executing at least one function provided by the data carrier. The terminal includes new operating software, a bootstrap loader for loading new operating software, and a terminal certificate providing authorization for transmitting a loading key. In authentication of the terminal, the terminal certificate is transmitted to the data carrier and verified there and a loading key is transmitted to the data carrier. The operation control of the data carrier changes over to the bootstrap loader which deletes the present operating software of the data carrier and transmits the new operating software using the loading key from the terminal. The new operating software is then verified and activated by the bootstrap loader which transfers the control of the data carrier to the new operating software.
