METHOD FOR READING ACCESS AUTHORISATIONS OR IDS FROM AT LEAST ONE OF CUSTOMER MEDIUM USING SEVERAL READERS OF AN ACCESS CONTROL DEVICE AND FOR EVALUATING THE READ IDS OR ACCESS RIGHTS

摘要

In the context of the method for reading out access authorizations or IDs from at least one customer medium by means of at least one reading device (3, 4, 5) of an access control device (2) and for evaluating the read-out IDs or access authorizations, all reading devices (3, 4, 5) activates and performs a parallel scan for IDs or access permissions, the read out IDs or access permissions being transmitted to a controller of the access control device (2) which transmits them to an evaluation unit (1) while the reading devices (3, 4, 5) continue scan for possible IDs or access authorizations, wherein if an evaluation reveals that a read access authorization is valid or a valid access authorization is assigned to a read-out ID, the reading devices (3, 4, 5) are deactivated and the access is activated by actuation of a blocking element (6 ) of the access control device granted w ird and wherein, if after a predetermined time since the activation of the reading devices (3, 4, 5), which corresponds to the time required for the readout of an access authorization or an ID by the slowest reading device (3, 4, 5) plus an applicable offset , no further IDs or access permissions are recognized as being valid, access is denied.
