Abstract
The disclosure relates to a method for reading at least one attribute stored in an ID token, wherein the ID token is assigned to a user, said method comprising: determining, by a terminal, of whether a contact-based interface of the ID token is present and can be used for data exchange with the terminal. If the ID token does not have the contact-based interface or this cannot be used, implementing a zero-knowledge authentication protocol via a contactless interface of the terminal and ID token;and deriving an ID token identifier by the terminal. If the ID token has the contact-based interface and this can be used, authenticating the user to the ID token via the contact-based interface; accessing to an ID token identifier by the terminal; sending of the ID token identifier from the terminal to an ID provider computer; use of the ID token identifier by the ID provider computer in order to authenticate the ID provider computer to the ID token; andread access of the ID provider computer to the at least one attribute stored in the ID token.
