Abstract
A tachograph includes at least one chip card reading unit and, at least one chip card with secure memory. Secured data transmission can be fed to the at least one chip card reading unit. On the at least one chip card, at least one user-defined piece of identification information is securely stored which is independent of a specified piece of identification information for a specified operation of the tachograph. The tachograph is constructed so as to authenticate the at least one chip card in accordance with the at least one piece of user-defined identification information, and to read data securely from the at least one chip card and/or to store data securely on the at least one chip card.
