A method for the pairing of exactly one first type of technical devices, first technical device, with exactly one second type of technical devices, second technical device, wherein the method comprises the following steps: a) generating access identifiers of first technical devices, storing these ones with respect to the first technical devices and sending these ones to the first and second technical devices by the central computer system, b) receiving and storing the sent access identifier in the first and second technical devices, c) generating device identifiers of individual first technical devices, storing these ones with respect to the corresponding first technical devices and sending these ones to the first technical devices by the central computer system, d) receiving and storing the device identifier in the first technical devices, e) periodically repeatedly sending out access identifiers, which are receivable in the close range, by a transmitter in the first technical devices, wherein a data telegram is sent out, which contains the access identifier and the device identifier of the first technical device, f) receiving the access identifiers by the second technical device, wherein if a second technical device receives at least one admissible data telegram from at least one first technical device, the pairing with the first technical device will be initiated, g) in case of an initiation, sending a data set by the second technical device to the central computer, which data set contains at least: an unequivocal identifier of the second technical device and the device identifier of the first technical device, h) receiving the data set from the second technical device by the central computer and pairing the first technical device and the second technical device for a data exchange between both technical devices. a) generating access identifiers of first technical devices, storing these ones with respect to the first technical devices and sending these ones to the first and second technical devices by the central computer system, b) receiving and storing the sent access identifier in the first and second technical devices, c) generating device identifiers of individual first technical devices, storing these ones with respect to the corresponding first technical devices and sending these ones to the first technical devices by the central computer system, d) receiving and storing the device identifier in the first technical devices, e) periodically repeatedly sending out access identifiers, which are receivable in the close range, by a transmitter in the first technical devices, wherein a data telegram is sent out, which contains the access identifier and the device identifier of the first technical device, f) receiving the access identifiers by the second technical device, wherein if a second technical device receives at least one admissible data telegram from at least one first technical device, the pairing with the first technical device will be initiated, g) in case of an initiation, sending a data set by the second technical device to the central computer, which data set contains at least: an unequivocal identifier of the second technical device and the device identifier of the first technical device, h) receiving the data set from the second technical device by the central computer and pairing the first technical device and the second technical device for a data exchange between both technical devices.
