An electronic apparatus includes a first storage device and a processor. The processor causes a server device to register the electronic apparatus by transmitting a first signal including identification information for identifying the first storage device, transmits, to the server device, a second signal including identification information of the first storage device and inquiring whether or not it is registered in the server device that data stored in the first storage device is to be erased, and erases the data stored in the first storage device when the electronic apparatus receives a third signal instructing erasure of the data stored in the first storage device. The third signal is transmitted when the identification information of the first storage device matches the identification information of the first storage device and it is registered in the server device that the data stored in the first storage device is to be erased.
