Abstract
In an access control device including a lock with a locking element, an actuating element for the locking element, an electronic key, 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 and/or the locking element for selectively locking or unlocking the lock. The electronic key includes 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 carrying the key is provided. The receiver unit is designed as a device separate from the lock and comprises at least one capacitive coupling surface such that, at a contact of the capacitive coupling surface or an approach of the capacitive coupling surface by said person, an alternating current circuit is closed and an electric flux is created across the receiver unit, which can be detected by the receiver unit.
