A storage apparatus includes a first memory, which is nonvolatile, a first controller that controls the first memory, a wireless antenna, a second memory, which is operable based on power supplied from the wireless antenna, and a second controller that is operable based on the power supplied from the wireless antenna, and performs communication using the wireless antenna. When performing communication with an external apparatus using the wireless antenna, the second controller performs authentication of the external apparatus, and stores in the second memory an authentication result indicating whether the authentication succeeded or failed. If the authentication result indicates that the authentication succeeded, the second controller permits reading by the external apparatus of first data from the second memory by communication using the wireless antenna or writing by the external apparatus of second data to the second memory by communication using the wireless antenna.
