Disclosed is an access control device including a lock with a locking element, an actuating element for the locking element, an electronic key, an electrical circuit including a receiver unit for receiving key identification data and an evaluation circuit for determining access authorization based on the received identification data, said evaluation circuit cooperating with the actuating element and/or the locking element for selectively locking or unlocking the lock, wherein the electronic key comprises means for generating a capacitive near field via which the identification data is emitted, and a device for coupling the capacitive near field to a person carrying the key, and that the receiver unit of the lock comprises at least one capacitive coupling surface such that an alternating current circuit closes at a contact of the lock, or an approach of the lock, by said person and an electric flux is created across the lock, which can be detected by the receiver unit.
