According to one embodiment, a wireless communication device includes a first interface, a first memory, a wireless antenna, a second memory and a second interface. The first interface is capable to electrically connect to a first host device. The first interface communicates with the first host device in accordance with an SD interface. The first memory includes a nonvolatile memory which operates based on power supplied through the first interface from the first host device. The wireless antenna generates power based on a radio wave from a second host device. The second memory is capable to operate based on power generated by the wireless antenna. The second memory has a memory capacity lower than the first memory. The second interface is capable to operate based on power generated by the wireless antenna. The second interface is connected to the second memory and the first interface.
