In an access control device including a lock (2) with a locking element, an actuating element (3) for the locking element, an electronic key (5), 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, the evaluation circuit cooperates with the actuating element (3) and/or the locking element for selectively locking or unlocking the lock (2). The electronic key (5) comprises means for generating a capacitive near field via which the identification data is emitted. Furthermore, a device for coupling the capacitive near field to the person (4) carrying the key (5) is provided, wherein the receiver unit of the lock (2) comprises at least one capacitive coupling surface such that an alternating current circuit closes at a contact of the lock (2), or an approach of the lock (2), by said person (4) and an electric flux is created across the lock (2), which can be detected by the receiver unit. |
