1. A system for controlling functional devices comprising:

  • a functional device;

    an unpowered token comprising an identifier for, and located in the vicinity of, the functional device;

    an electronic bridge connected to the functional device and configured to receive control instructions and pass the control instructions to the functional device;

    a server connected to the electronic bridge and configured to generate said control instructions;

    wherein the server is configured to;

    receive, from a personal mobile electronic device located in the vicinity of the functional device, the respective identifier of the functional device and an identification of the personal mobile electronic device;

    retrieve from a database a permission level for a user associated with the identification to access the functional device; and

    if the permission level indicates that permission is granted, generate a TCP/IP packet comprising an access granted control instruction and send the packet to the electronic bridge, upon which said electronic bridge passes the access granted control instruction to the functional device causing it to operate; and

    wherein the electronic bridge has;

    circuits adapted to detect trains of digital pulses from at least one other functional device; and

    a central processing unit configured to receive said trains of digital pulses from said circuits, start processing said trains of digital pulses into strings of data signals without first determining a protocol format of said trains of digital pulses, build further TCP/IP packets including said strings of data signals, and send said further TCP/IP packets to the server.
