Abstract (en)

[origin: US5585614A] This access control device has at least one local control device (10) connected to a central control device (11) containing a local computer (18), an issuing station (12) for control cards and a lockable entry installation (13). At the issuing station (12) are issued portable control cards (47) with an electronic identity number is stored at each issue. A transmitting device 921) fitted at the entry installation (13) transmits a continuous series of signals corresponding to identity numbers recognized by the local computer (18) as valid. As soon as the comparator circuit finds a correspondence between transmitted and stored identity numbers, the transmission circuit of the control card is activated to send a release signal to open the entry installation, whereby the power to transmit the release signal is taken from the signals transmitted by the transmission device.
