Abstract
A communication control method for a communication device includes (i) blocking communication of the communication device with a wireless device by causing a metal-containing member to be close to the communication antenna among a plurality of antennas, or by covering at least a part of the communication antenna with the metal-containing member; (ii) charging a capacitor by the communication device, based on energy acquired by an energy acquisition antenna of the communication device, regardless of whether the communication device can communicate with the wireless device, to keep a voltage of the capacitor equal to or higher than the predetermined value; and (iii) resuming communication of the communication device with the wireless device when the metal-containing member is stopped from being close to the communication antenna or when at least a part of the communication antenna is stopped from being covered with the metal-containing member.
