The present invention relates to a method for carrying out passage and authorisation checks of objects, such as persons or vehicles, with the aid of an identification system that uses radio frequencies, so-called RFID (Radio Frequency Identification) or corresponding radio links, said system including identification tags (ID-tags) ( 1 ) and communicators ( 2 ), wherein each ID-tag is designed to receive a signal sent by a communicator ( 2 ) and to reflect or re-send said signal in a modulated state, wherein the communicators are connected to central computer ( 7 ) and a database ( 8 ). The invention is characterised in that the memory ( 5 ) of the ID-tags includes a code which identifies the object to which the ID-tag truly belongs, said code being caused to be transferred to said computer ( 7 ) via a communicator ( 2 ); in that one or more ID-tags is/are caused to be read by a communicator ( 2 ) essentially simultaneously; in that an object-specific machine-readable parameter, such as the facial appearance of a person or the colour or shape of an object, or some other machine readable parameter, is caused to be read mechanically by a reading device ( 9 ) for one or more objects within the reading area of said device; in that the parameter read in respect of one or more objects is caused to be transferred to said computer ( 7 ); in that the computer ( 7 ) is caused to compare the read parameters with respect to the object or objects that has or have been read with corresponding stored object-specific parameters for read ID-tags; and in that in the event of a predetermined deviation between said parameters one or more ID-tags are considered not to belong to the passing objects. |
