Verfahren und System zur Zugangskontrolle

A method for access control is proposed, wherein verification of an access authorisation is effected by way of evaluating an ID sent at regular intervals from a mobile electronic device nearest an access control device (3, 4, 5, 6) or a data carrier nearest an access control device (3, 4, 5, 6) via the Bluetooth Low Energy Standard as part of a "broadcasting", to which at least one access authorisation is unequivocally assigned, which is received by BLE transceiver units (TRX-1, TRX-2, TRX-3, TRX-4) connected to a computer comprising a CPU and storage means within range of the mobile electronic device or the data carrier, wherein localisation of the mobile electronic devices or the data carriers is carried out by means of evaluation of the RSSI (Received Signal Strength Indicator), wherein the signal strength is measured, with which that signal of a mobile electronic device or a data carrier is received, which contains the ID of BLE transceiver units (TRX-1, TRX-2, TRX-3, TRX-4).
