Electronic padlock (CAD) intended to be placed on an electrical device, said electronic padlock comprising: - an electromechanical system (EM) supplied with power by a power source and capable of allowing or preventing the opening of the electronic padlock, - a communication interface for exchanging data through a communication link with one or more mobile terminals, - processing means (CPU1) that are arranged to handle requests to open or to close the electronic padlock (CAD) transmitted by said one or more mobile terminals, - a non-volatile memory (M1), where the processing means include: - a module for storing, in the non-volatile memory (M1), close requests transmitted by each mobile terminal through the communication link, - a module for generating a different unique code associated with each stored close request, - a module for transmitting the unique code to the mobile terminal that has transmitted the close request, - a module for storing, in the non-volatile memory (M1), an image of said unique code in conjunction with the stored close request, - a module for comparing the unique code received from a mobile terminal with the image thereof when an open request is transmitted by said mobile terminal, characterized in that the processing means (CPU1) include: - a module for verifying pending close requests and a module for allowing the opening of the electronic padlock, which modules are activated by the comparison module if the unique code received in the open request is identical to the stored image and if no other close request is stored, - a module for erasing the image of the unique code from its non-volatile memory (M1) when it allows opening following receipt of an open request. - an electromechanical system (EM) supplied with power by a power source and capable of allowing or preventing the opening of the electronic padlock, - a communication interface for exchanging data through a communication link with one or more mobile terminals, - processing means (CPU1) that are arranged to handle requests to open or to close the electronic padlock (CAD) transmitted by said one or more mobile terminals, - a non-volatile memory (M1), - a module for storing, in the non-volatile memory (M1), close requests transmitted by each mobile terminal through the communication link, - a module for generating a different unique code associated with each stored close request, - a module for transmitting the unique code to the mobile terminal that has transmitted the close request, - a module for storing, in the non-volatile memory (M1), an image of said unique code in conjunction with the stored close request, - a module for comparing the unique code received from a mobile terminal with the image thereof when an open request is transmitted by said mobile terminal, - a module for verifying pending close requests and a module for allowing the opening of the electronic padlock, which modules are activated by the comparison module if the unique code received in the open request is identical to the stored image and if no other close request is stored, - a module for erasing the image of the unique code from its non-volatile memory (M1) when it allows opening following receipt of an open request. <EOS>
