1. A system for charging devices, the system comprising:
- a slave device comprising;
an antenna to receive a radio frequency (RF) beam; and
a power generation module connected to the antenna that converts RF energy received by the slave antenna to power;
a master device comprising;
a directional antenna to direct said RF beam to the antenna of the slave device; and
a module that provides power to the directional antenna of the master device; and
a database that stores identifying information of a set of slaves devices that are authorized to receive the directional RF beam from the master device,wherein the master device (1) monitors a power status of the slave device, (2) receives an identifying information of the slave device before the slave device is fully charged, (3) compares the received identification of the slave device with the identifying information of the authorized set of slave devices, and (4) continues to direct the directional RF beam to the slave device only when the identifying information of the slave device matches the identifying information of one of the slave devices in the set of authorized slave devices.
