1. A control system for remotely controlling a supply of power to a plurality of electrical appliances, the system comprising:

  • one or more sockets attached to the main power supply, wherein a first electrical appliance of the plurality of electrical appliances is connectable to the main power supply via a first socket of the one or more sockets to which a plug of the first electrical appliance is attached;

    a transceiver located at one of the first socket and the plug of the first electrical appliance, wherein the transceiver is automatically activated responsive to inserting the plug of the first electrical appliance in the first socket, wherein the transceiver is communicatively connected to the control system;

    a tag provided at a second one of the first socket and the plug of the first electrical appliance, wherein the tag is in close proximity to the transceiver and is capable of receiving communication from the transceiver, wherein the tag includes an inductor that is coupled to a first relay switch in one of the first socket and the plug of the first electrical appliance, wherein the first relay switch, when closed, connects the first electrical appliance and the main power supply in series, and wherein the inductor holds the first relay switch closed while the tag is being stimulated by the transceiver; and

    a controller that is communicatively connected to the transceiver and which;

    interrogates, via the transceiver, the tag to determine a unique identifier of the tag, wherein the unique identifier enables the control system to control whether power is applied to the transceiver;

    receives, from the transceiver, the unique identifier of the tag;

    in response to the receiving an instruction to disconnect power to the first electrical appliance, deactivates the transceiver, wherein deactivation of the transceiver deactivates the plug of the first electrical appliance at the first socket and disconnects the main power supply from the first electrical appliance; and

    in response to the control system receiving an instruction to connect power to the first electrical appliance, activates the transceiver, wherein activation of the transceiver stimulates the tag and activates the plug of the first electrical appliance at the first socket to connect the main power supply to the first electrical appliance.
