An electronically controlled smart lock control module (hereinafter referred to as a smart lock) installed at the position of the fuel dispenser lock ensures the controlled opening and closing of the mechanical lock of the fuel dispenser. It also takes into account the transformation of the existing tanker in the market. The smart lock and associated control system can record the opening and closing of each dispenser door to avoid the oil stealing phenomenon caused by the uncontrolled opening of the current fuel dispenser.  And the remote authorization to switch lock can be realized with the matched POS machine.
