APPARATUS FOR ACCESS CONTROL, AND READ/WRITE DEVICE Russian patent published in 2012 - IPC G08B13/26 G06K7/08 

FIELD: information technology.

SUBSTANCE: access control device has 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 a processing circuit for determining access authorisation based on the received identification data, wherein the processing circuit interacts 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 are transmitted, and a device for coupling the capacitive near field to the person carrying the key, wherein the receiver unit is designed as a wall or table reading device separate from the lock and the actuating element, and has at least two electrodes and includes 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 current flows through the receiver unit, which can be detected by the receiver unit.

EFFECT: easier access monitoring and improved system for controlling access, aimed at increasing reliability.
