Abstract
According to one embodiment, a memory device includes a nonvolatile memory, a first controller which controls the nonvolatile memory, a wireless antenna, a memory, a second controller, and a third controller. The wireless antenna generates electric power based on a radio wave from a first external device. The memory is operable based on the generated electric power. The second controller is operable based on the generated electric power and controls communication using the wireless antenna. The third controller controls data copy or transfer between the nonvolatile memory and the memory. The third controller receives, from a second external device, identification information and stores the identification information in the memory. The second controller transmits login information and identification information stored in the memory to the first external device via the wireless antenna.
