1. A method for selective wireless charging of a slave device, said method comprising:
- using one or more antennas to form an RF beam using RF signals from a transmitter in a master device;
selectively charging said slave device if said slave device has authorized being charged;
selectively confining said RF beam to a space where said slave device is situated for charging said slave device; and
said selectively charging comprises said slave device registering and providing identifying information in a slave information 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.
