In an apparatus for access control with a lock having a blocking element, with an operating element for the blocking element, an electronic key, a reception unit for receiving identified on data for the key and an evaluation circuit for establishing the access authorization on the basis of the received identification data, the evaluation circuit interacts with the operating element and/or the blocking element for the purpose of selectively releasing or blocking the lock. The electronic key has means for producing a capacitive near field which is used to transmit the identification data. In addition, a device for coupling the capacitive near field onto the person carrying the key is provided. The reception unit is in the form of a device which is separate from the lock, and comprises at least one capacitive coupling face, so that when the capacitive coupling face is touched or when the capacitive coupling face is approached by the person an AC circuit is closed and a flow of electricity is produced through the reception unit and can be detected by the reception unit. |
