1. A method for access control, in an access control system with one or more lane access, each lane (D, E, F, H) having an access control device (3, 4, 5, 6) assigned thereto, which comprises at least one bluetooth low energy standard transceiver unit (TRX-1, TRX-2, TRX-3, TRX-4), wherein verification of access authorization comprisesevaluating an ID sent at regular intervals from the mobile electronic device nearest the access control device (3, 4, 5, 6) or a data carrier nearest the access control device (3, 4, 5, 6), via the bluetooth low energy standard transceiver unit (TRX-1, TRX-2, TRX-3, TRX-4), as part of a “

    , to which at least one access authorization is unequivocally assigned,receiving the at least one access authorization by the bluetooth low energy standard transceiver units (TRX-1, TRX-2, TRX-3, TRX-4) connected to a computer comprising a central processing unit and storage means within range of the mobile electronic device or the data carrier,localizing the mobile electronic devices or the data carriers by evaluating a Received Signal Strength Indicator (RSSI), by measuring the received signal strength of the mobile electronic device or the data carrier, which contains the ID of the bluetooth low energy standard transceiver units (TRX-1, TRX-2, TRX-3, TRX-4);

    using a ratio of the Received Signal Strength Indicators, of which the bluetooth low energy standard transceiver units (TRX-1, TRX-2, TRX-3, TRX-4) of the access control system have received the signal of the mobile electronic device or the data carrier containing the ID;

    ascertaining the ratio of distances of the mobile electronic device or the data carrier to the bluetooth low energy standard transceiver units (TRX-1, TRX-2, TRX-3, TRX-4); and

    ascertaining the lane in which the mobile electronic device or the data carrier is located by using the relative distances of the mobile electronic device or the data carrier to the bluetooth low energy standard transceiver units (TRX-1, TRX-2, TRX-3, TRX-4).
