Abstract
An electronic access authorization system maintains location-dependent and/or time-dependent validity data which can be read out wirelessly by an access control device (4), which data can be acquired online or, in the case of an accreditation, can be requested online as a special form of access authorization, and which can be transferred following successful issuance in electronic form to an electronic terminal (1) of a user. Changes, on the part of the issuer of the access authorization, to the validity data of the access authorization can be transferred via a data communication connection between a server (2) of the issuer of the access authorization and the electronic terminal (1) to the electronic access authorization stored in the electronic terminal (1) and displayed on a display device (5) of the electronic terminal.
