Abstract (en)
An access control system (10) comprises a radio interface (12) configured to communicate with a portable user device (20), an electroacoustic transducer (13, 14), and a control circuit (11). The control circuit (11) is configured to selectively activate an actuator (7) in an access grant procedure based on a propagation time of the acoustic signal between the electroacoustic transducer (13, 14) and the portable user device (20).
