Abstract
An access control apparatus has a blocking element (1) which is moved by a motor (2) or similar actuator controlled via a control means.

The motor (2) can be driven by the first access authorization reader (12, 14) in the normal case, that is, upon valid reading of access authorization by the first access authorization reader (12, 14), by the second access authorization reader (13, 15) upon detection of a person and invalid reading of access authorization by the first access authorization reader (12, 14), and by the first access authorization reader again upon valid reading of access authorization of the detected person by the second access authorization reader (13, 15).
