Method for reading out access authorizations or ID's from at least one customer medium by means of at least one reader of an access control device and for evaluating the selected ID's or access authorizations

A method of reading out access authorizations or IDs from at least one customer medium by at least one reader (3, 4, 5) of an access control device (2) and for evaluating a selected ID or a selected access authorization,

• wherein all of the readers (3, 4, 5) are activated and perform a scan, in parallel, for at least one ID or access authorization, which is contained or stored in at least one customer medium,
• each selected ID or access authorization is transmitted to a controller of the access control device (2), which temporarily stores each selected ID or access authorization in the access control device (2), and transmits each selected ID or access authorization to an evaluation unit (1) in prescribed intervals or transmits each selected ID or access authorization to the evaluation unit (1) immediately after selection, while the readers (3, 4, 5) continue to scan for other possible IDs or access authorizations,
• if an evaluation in the evaluation unit (1) finds that the selected access authorization is valid or a valid access authorization was allocated to the selected ID, the readers (3, 4, 5) are deactivated, and access is granted by actuating and opening a locking element (6) of the access control device, and
• if, after a prescribed time since the readers (3, 4, 5) were activated that corresponds to the time required by a slowest reader (3, 4, 5) to read out an access authorization or an ID plus an applicable offset, and no further IDs or access authorizations are read out, transmitted to the evaluation unit, (1) and recognized as valid, then access is denied.
