1. A master device for wirelessly providing power to a set of slave devices, the master device comprising:
- a power transmitter configured to wirelessly provide power to the set of slave devices;
the master device configured to;
receive an identification of each slave device in the set of slave devices;
compare the identification received from each of the slave devices with identifications of slave devices stored in a database, the database storing identification of slaves devices that are authorized to wirelessly receive power from the master device; and
wirelessly provide, utilizing the power transmitter, power to one or more slave devices in the set of slave devices having an identification that matches the identification of an authorized slave device stored in the database.

Abstract
Some embodiments provide a system for charging devices. The system includes a master device and a slave device. Some embodiments provide a method for charging devices in a system that includes a slave device and a master device. The slave device includes (1) an antenna to receive a radio frequency (RF) beam and (2) a power generation module connected to the antenna that converts RF energy received by the slave antenna to power. The master device includes (1) a directional antenna to direct RF power to the antenna of the slave device and (2) a module that provides power to the directional antenna of the master device.
