Abstract
There is provided a mobile terminal and an IC chip management method that make it possible to protect an IC chip from unauthorized access. An IC chip of a device includes a memory forming a protection-target region that is a storage region for predetermined information targeted for protection and a specific-state region that is a storage region for state information representing a specific state of a user. The device includes the IC chip and a control section that performs control so as to bring the protection-target region to a usage-unpermitted state in the case where, in the IC chip, the state information is changed to information representing a state in which the predetermined information is not used. The present technology can be applied to a near-field wireless communication system.
