Wireless communication device, power transmitter, and IC card device
First Claim
1. A wireless communication device, comprising:
- a power receiving wireless communicator to receive power and perform wireless communication utilizing the power;
a storage to store a portion of the power received by the power receiving wireless communicator;
a first wireless communicator to perform wireless communication faster and more efficiently than the power receiving wireless communicator by utilizing the power stored in the storage, when an amount of the power stored in the storage unit exceeds a first reference level; and
a controller to generate a first trigger signal indicating that the amount of the power stored in the storage has exceeded the first reference level;
wherein the power receiving wireless communicator includes;
a power receiver to receive the power and supply the portion of the power to the storage; and
a second wireless communicator to perform wireless communication by utilizing the power received by the power receiver;
wherein the second wireless communicator transmits an RF signal including the first trigger signal; and
wherein the first wireless communicator starts wireless communication when the first trigger signal is supplied from the controller.
